The present disclosure relates to containment vessel support systems and the deployment, configuration, and modularity of nuclear power plants.
Pollution, cost, and other detrimental aspects of fossil fuels have led to an increasing focus on alternative energy sources such as wind, solar, geothermal, hydroelectric, and biofuels as valuable alternatives to fossil fuels; however, there are numerous limitations for renewable energy sources: siting constraints, environmental impacts, limited reliability, and low capacity. Inexorably, the global need for reliable, safe, secure, and inexpensive energy rapidly grows. Consumers of electricity, heat, utilities, and industrial commodities require energy sources that are sustainable, low-cost, produce low carbon emissions, and have high capacity factor. Novel nuclear power plant designs can meet this need. To overcome the drawbacks of earlier designs, such plants should be adaptable to areas with existing grid infrastructure, minimize development footprint (e.g., near expanding coastal population centers), and entail the least possible development of new transmission infrastructure. To be secure and sustainable, they must be robust against potential impacts of climate change, including sea level rise and dwindling supplies of freshwater for cooling. They should also be robust against mechanical failures, malicious attack, human error, and natural disasters, including seismic events and tsunamis. Low population density in proximity to development sites is preferable because it tends to mitigate emergency-planning concerns. Also, novel designs should avoid the exceedingly long lead times for key components that result from complex processes involved in finding and approving suitable sites and from stick-build construction processes that vary from site to site. Site-specific design, approval, and construction processes results in high construction costs and long project durations that make nuclear power projects difficult to finance and insure and more complex to operate. The inventors have identified needs that exist for methods and systems that standardize nuclear power plant site engineering, procurement, and construction, allowing for faster design and deployment to a wider range of potential sites. The inventors have also identified that novel baseload generating sources should complement increasing renewables penetration and provide capacity for load following and alternative product support in the form of process heat generation.
The inventors have recognized that manufactured nuclear plants (MNPs), e.g., nuclear plants partly or wholly manufactured in shipyards and towed to locations on or near shorelines, can meet the whole range of foregoing needs. For example, the inventors have recognized that offshore MNPs they require relatively little onshore land development (mostly for landfall of transmission lines) and are immersed in an inexhaustible supply of coolant water. If floating, they are inherently secure against sea-level rise, the direct impacts of earthquakes, and (if sufficiently far offshore) tsunamis. Security concerns are mitigated by the MNP's open sea-and-air environment, which make any form of approach relatively easy to detect. Also, a structure sealed against the oceanic environment is inherently more difficult to infiltrate, ceteris paribus, than a sprawling terrestrial facility. Further, sectional manufacture and assembly using well-known shipyard techniques can lower MNP cost as compared to terrestrial construction of a comparable-sized plant, because preassembled module size is severely constrained on land by the difficulty of overland transport. Practical shipyard module size for MNP construction is at least an order of magnitude greater than for terrestrial construction, and can be organized on the basis of efficiency and engineering considerations. Additionally, site-specific variations in context (terrain, geohydrology, settlement patterns, etc.), which have invariably raised construction costs for land-based plants despite efforts to standardize designs, are greatly mitigated for MNPs. Also, MNPs can be easily relocated at any time (e.g., for re-deployment, in response to changing security concerns, or for transport to a decommissioning location), in contrast to terrestrial nuclear power plants, which are non-relocatable.
Thus, the inventors have recognized that MNPs potentially offer an elegant solution to some of the most intractable costs of conventional, onshore nuclear power plants. MNPs may also be advantageously constructed in a standardized, modular manner using shipyard techniques and towed to its service location, where it may be anchored as a floating unit or grounded in relatively shallow water.
The inventors have recognized the important advent of commercially viable small modular reactors (SMRs), e.g., the NuScale Power Module™, which generates a quantity of steam capable of support an electrical power output of approximately 50 megawatts (MW). SMRs offer a number of potential advantages over the relatively large (i.e., gigawatt-scale) nuclear reactors previously employed for commercial power generation; these advantages include but are not limited to lower accident risk due to passive internal coolant circulation and other features, standardized mass manufacture, adjustment of total generating capacity of a multi-SMR facility by addition or removal of SMRs, swap-out and refueling capability for individual SMRs at a multi-SMR facility without shutdown of the whole facility, and deliverability by truck or barge enabled by small form factor (e.g., 2.7 meters wide by 20 meters high).
To reduce the per-unit cost of electricity from SMRs to competitive levels and thus enable the advantages of SMRs to be fully realized, multiple SMRs will typically be located at single generating facilities. Moreover, it is desirable that the economic and other advantages of MNPs be combined with the advantages of SMRs. However, nuclear power station designs incorporating SMRs into MNPs have not hitherto been disclosed.
There is therefore a need for systems and methods of incorporating SMRs into MNPs.
The prior art has provided for the manufacture of SMRs of various types, and for their deployment, singly or in groups, in nuclear power stations of various configurations. All such deployments and configurations, and the methods by which they are built, are readily distinguishable from the methods and systems of embodiments, as shall be made clear hereinbelow.
In particular, the prior art includes a number of types of constructed sites (a.k.a. “artificial islands”) for nuclear power plants either adjacent to, surrounded by, or floating upon bodies of water such as rivers, lakes, or seas; the text Islands for Offshore Nuclear Power (Binnie & Partners, London, 1982), whose contents are incorporated herein by reference, describes a range of such constructed sites, which are further discussed hereinbelow with reference to several of the Figures. Also comprised by the prior art are methods for the delivery of certain components of power plants by flotation to prepared onshore or near-shore sites. The methods of the prior art include the use of dredged channels to enable the delivery of power-plant components to a littoral site where the components may be grounded (e.g., by flooding and filling). The methods of the prior art also include partial disassembly of large reactor containments to enable passage along constrained delivery routes (e.g., the St. Lawrence Seaway); such disassembly requires technically difficult and therefore expensive welding assembly of the unified containment at the final installation site. The methods of the prior art also include the delivery and positioning (e.g., by grounding) of caissons for the construction of breakwaters or protective barriers around such plants. The methods of the prior art also include the deployment of SMRs in common enclosures, e.g., proposals by NuScale Power, Inc. for the colocation of some number of SMRs (e.g., six SMRs) of approximately 50 MW capacity each within a single structure, where the number of SMRs are be immersed in a single coolant pool. Also, the methods of the prior art provide the construction of vertically-oriented floating structures containing nuclear reactors.
All this prior art, as well as prior art not described herein, are fundamentally distinguishable from all of the embodiments. Embodiments comprise systems and methods for the delivery of nuclear generation facilities or portions of such facilities, including but not limited to SMRs, structures to house and service multiple SMRs, and turbine houses, by flotation and/or land transport in a manner that provides for the special security needs of modern nuclear power stations, and exploits the small size and other unique properties of integrated SMRs (e.g., self-containment of cores with primary heat-exchange loops). Embodiments advantageously enable the potential separate delivery by water and/or land of one or more SMRs, reactor house (structure that will house and service the SMRs), turbine house, and aircraft impact shield to offshore, littoral, and coastal sites. Moreover, embodiments include racked or arrayed SMRs in configurations that obviate the use of a single, massive aircraft impact shield structure custom-built onsite in favor of a relatively low-profile shield structure that can be assembled onsite from sub-modules, or delivered as a module, and readily mated with a flotation-delivered plant structures. These and other distinguishing aspects of embodiments along with various advantages will be clarified hereinbelow with reference to the Figures.

In embodiments, the term “ONP,” may be understood to encompass, except where context indicates otherwise, such an offshore nuclear platform, which in embodiments is assembled in a shipyard, primarily from manufactured components, and floated to a marine site where it will produce electricity or other products.

An individual ONP or “unit” typically contains one or more nuclear reactors, a turbine generator set, and associated systems for navigation, cooling, control, safety, power transmission, crew maintenance, and other functions. Units may be deployed in a variety of arrangements, e.g., as solitary units or in clusters. Unit deployment occurs in a complex environment having physical, economic, regulatory, political, military, and other facets that motivate implementation of both necessary and desirable system capabilities while constraining provision of those capabilities. Embodiments of the disclosure enable the provision of ONP capabilities within various constraints in a more economical manner than is enabled by the prior art.
The prior art includes methods for constructing terrestrial reactor systems and ocean-going reactors for vessel propulsive power (e.g., in submarines).

The prior art also includes designs for ONPs such as the U.S.S. Sturgis MH-1A floating nuclear power plant (c. 1968-76) and recent Russian and Chinese design proposals. Such designs have featured the mounting of relatively small reactors (e.g., ˜10-100 MW) in repurposed naval vessels or barge-like structures. None of these designs include inventive arrangements similar to those described herein. Nor do any of the methods of the prior art employ the fully modularized approach to construction described herein, which is employed in the assembly of some ONPs, in accordance with the many embodiments of the present disclosure.

The unit's environment may be defined by the capabilities that various stakeholders require, as well as the physical constraints of the environment, such as a marine environment.
In embodiments, the term “unit deployment” may be understood to encompass, except where context indicates otherwise, (system configurations) is a configuration of the structural modules and nuclear, marine, accessory, and contingency systems arranged as a unit superstructure that satisfies the requirements of a unit environment.
In embodiments, the term “function of interest” may be understood to encompass, except where context indicates otherwise, an action, process, or capability involved in the lifecycle of nuclear power plants and marine vessels performed by systems on, interfacing, or associated with one or more ONP Units.

In the drawings, like reference characters generally refer to the same parts throughout the different views. Also, the drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the of the examples in the disclosure. In the following description, various embodiments of the present disclosure are described with reference to the following drawings, in which:
Provided herein are methods, systems, components and the like for design, development, delivery, deployment, and operation of nuclear power plants, including offshore nuclear power (ONP) units, that are designed to be assembled in a shipyard from standardized, manufactured components and floated to a marine environment where they are operated to produce electricity for delivery to an electrical grid and/or for other purposes, such as to enable various industrial, agricultural or other processes and/or to enable production of various products. Also, provided herein are efficient and advantageous systems and methods for the support of a reactor containment vessel that includes an ONP in a manner that transfers the weight forces of the containment vessel to portions of the ONP and ultimately to the ONP's environment.
ONPs can meet the whole range of foregoing needs. For example, they require relatively little onshore land development (mostly for landfall of transmission lines) and are immersed in an inexhaustible supply of coolant water. If floating, they can be inherently secure against sea-level rise, the direct impacts of earthquakes, and (if sufficiently far offshore) tsunamis. Security concerns can be mitigated by the ONP's open sea-and-air environment, which can make any form of approach relatively easy to detect. Also, a structure sealed against the oceanic environment can be inherently more difficult to infiltrate, ceteris paribus, than a sprawling terrestrial facility. Further, modular manufacture and assembly with the contribution of well-known shipyard techniques can be shown to lower ONP cost and associated risk as compared to terrestrial construction of a comparable-sized plant, because preassembled module size can be severely constrained on land by the difficulty of overland transport. Practical shipyard module size for ONP construction is at least an order of magnitude greater than for terrestrial construction, and can be organized on the basis of efficiency and engineering considerations. Additionally, site-specific variations in context (terrain, geohydrology, settlement patterns, etc.), which have invariably raised construction costs for land-based plants despite efforts to standardize designs, can be greatly mitigated for ONPs. Also, ONPs can be easily relocated at any time (e.g., for re-deployment, in response to changing security concerns, or for transport to a decommissioning location), in contrast to terrestrial nuclear power plants, which are non-relocatable.
Thus, ONPs potentially offer an elegant solution to some of the most intractable costs of conventional, onshore nuclear power plants. It will be appreciated in light of the disclosure that ONPs also present many novel design challenges including, but are not limited to, vulnerability to loss of offsite power, continual erratic movement even of the most massive components (e.g., turbines, pumps, generators) due to wave action, the structural threat posed by extreme winds and waves, the corrosive effects of seawater, secure anchorage of the unit, vulnerability to submarine as well as other forms of assault, the secure loading of radioactive materials onto and off of the unit, and many combinations thereof. Other challenges of operation in a marine environment can include constraints on system delivery (such as water depths, heights of bridges that may block transport to marine sites, and the like), security challenges (such as resulting from the absence of conventional defense perimeters and remoteness of backup security operations), environmental sensitivity (e.g., system impacts on marine life), and the like. The inventors have therefore identified needs for nuclear power design and construction that is suitable for marine environments. Moreover, the inventors have identified needs for methods and systems of standardized ONP design and construction that allow for faster and lower-cost design, construction, and deployment to a wider range of available sites of ONPs meeting all relevant design challenges.
One inherent challenge of ONP design can be the disposition and support of essential components or subsystems within the overall ONP unit. In an onshore nuclear power plant, the main considerations governing disposition of components are simplicity and proximity: for example, a typical terrestrial-based turbine-house layout is linear, with turbines and other major components lined up in a row, with often a second, lower level for a condensate system. It will be appreciated in light of the disclosure that such terrestrial-based arrangements are not practical for some ONP designs. For example, one class of ONP designs has an overall buoy-like (vertical) geometry that is highly resistant to capsizing. In such a design, the approximate overall form of the plant is a vertically oriented cylinder. Conventional, linear, and terrestrial-based layouts are less favorable if they were incorporated into such buoy-like (vertical) geometry. Moreover, it will be appreciated in light of the disclosure that the terrestrial construction practice of supporting large, heavy components such as the reactor itself, generators, condensers, and the like using massive concrete plinths communicating their loads more or less directly to the Earth is unfavorable for ONP construction. Concrete is used in terrestrial-based system, but it provides less strength per unit mass (and per unit volume) than steel and it consumes available interior volume or mandates greater total displacement of a floating ONP. Further, loads borne by concrete structures in a floating structure must typically be communicated secondarily to steel structures in order to be communicated to that portion of the structure's hull in contact with the surrounding water. As such, a concrete plinth would tend to be additional to, rather than alternative to, steel supportive structures. Herein, “steel” refers broadly to any metallic substance used for structural purposes in an ONP.
In embodiments, this disclosure refers to various marine environments, including offshore marine environments (such as where a nuclear unit or platform is mounted or moored to an ocean floor, sea floor, or the like), coastal marine environments (such as where a unit or platform is mounted or moored on or near a coast or other interface of a body or water with land, such as in a natural or man-made bay, port, harbor, inlet, or the like), river marine environments (such as where a unit or platform is floated up river and mounted or moored on a river floor or near a river that serves as a water source for the unit or platform), lake marine environments and the like. Except where context indicates otherwise, references to any one of these marine environments should be understood to encompass similar embodiments for the other marine environments described throughout this disclosure. For example, a reference to an ONP, or offshore platform, should be understood to encompass not only ocean embodiments, but also embodiments where a platform is in or near a river environment, such as having been floated up river and positioned in or near the river, except where context specifically requires a more specific marine environment.
In various cases, this disclosure refers to a nuclear power platform, a nuclear platform, a nuclear power plant unit, a platform, and the like. Such references should be understood to be used interchangeably except where context indicates otherwise.
The inventors have identified a need for a system and method of arranging, interconnecting, assembling, and operating the essential components of a nuclear power plant in an offshore nuclear power plant, where such a system and method should include methods for the support of massive components while making little or no use of heavy concrete plinths or supports. In particular, for an ONP that is assembled in a shipyard from prefabricated sub-units and floated to a site where the ONP will produce power, the inventors have identified a need that exists for reactor containment-vessel support structures that are lighter, less voluminous, and easier to shape in a manufacturing facility and assemble in a shipyard than the concrete structures typically used for containment support in terrestrial nuclear power plants.
Herein, a “Unit” is an individual ONP, that is, a structure containing a nuclear power plant preferably assembled in a dry-dock or other berths at a shipyard and capable of being deployed to and operating in a marine environment. The Unit typically contains one or more nuclear reactors, a turbine generator set, supporting auxiliary systems, and accessory systems for adapting the ONP unit to the environment it is deployed in, such as for navigation, cooling, control, safety, power transmission, crew maintenance, and other functions. As shall be clarified with references to Figures herein, units may be deployed in a variety of arrangements, e.g., as solitary units or in clusters. Units operate in complex environments having physical, economic, regulatory, political, military, and other facets that dictate required system capabilities and constrain the operations of units. It can be shown that embodiments of the disclosure enable the provision of ONP capabilities within various constraints in a more economical manner than what was provided by the prior art.
Embodiments of the present disclosure include modularization of an ONP system across a range of material and functional levels in a manner that facilitates design, manufacture, and maintenance of the ONP as well as various interactions of the ONP system with its environment, both material (ocean, grid, etc.) and non-material (legal, financial, etc.). Such modularization will be clarified with reference to Figures hereinbelow. Herein, an “ONP system” may include a single ONP unit or a multiplicity of such units, and typically includes provisions for interaction of the system's one or more ONPs with their environment. Such provision will be clarified with reference to Figures herein. Herein, reference is often made to a single ONP for simplicity, but such reference does not exclude many embodiments including multiple ONPs
The associated systems 104, 106, 108, 110 can interact with the Unit Configuration via Interface Systems 122, 124, 126, 128. In embodiments, the terms “interface,” “interface system,” and “interfacing system” may be understood to encompass, except where context indicates otherwise, one or more systems, services, components, processes, or the like that facilitate interaction or interconnection of systems within an ONP or between one or more systems of the ONP with a system that is external to the ONP, or between the ONP and associated systems, or between systems associated with an ONP. Interface Systems may include software interfaces (including user interfaces for humans and machine interfaces, such as application programming interfaces (APIs), data interfaces, network interfaces (including ports, gateways, connectors, bridges, switches, routers, access points, and the like), communications interfaces, fluid interfaces (such as valves, pipes, conduits, hoses and the like), thermal interfaces (such as for enabling movement of heat by radiation, convection or the like), electrical interfaces (such as wires, switches, plugs, connectors and many others), structural interfaces (such as connectors, fasteners, inter-locks, and many others), or legal and fiscal interfaces (contracts, loans, deeds, and many others). Thus, Interface Systems may include both material and non-material systems and methods. For example, the Interface System 122 for interfacing the Unit Configuration 102 with Ownership 104 can include legal arrangements (e.g., deeds, contracts); the Interface system 128 for interfacing the Unit Configuration 102 with the Environment 110 can material arrangements (e.g., tethers, tenders, sensor and warning systems, buoyancy systems).
The Ownership system 104 can include Owners 130 and Interface Systems 122; the Implementation system 106 can include Implementers 132 (e.g., builders, defenders, maintainers) and Interface Systems 124; the Consumer's system can include Consumers 134 and Interface Systems 126; and the Environment system can include the natural Physical Environment 136 and Interface Systems 128. The physical environment for an ONP may be characterized by various relevant aspects, including topography (such as of the ocean floor or a coastline), seafloor depth, wave height (typical and extraordinary), tides, atmospheric conditions, climate, weather (typical and extraordinary), geology (including seismic and thermal activity and seafloor characteristics), marine conditions (such as marine life, water temperatures, salinity, and the like), and many other characteristics. Associated systems not depicted in
The Systems 202 may include one or more Plant Systems 210. In embodiments, the terms “plant system,” or “nuclear plant system,” and “power conversion plant system” may be understood to encompass, except where context indicates otherwise, systems involved in the operation of a nuclear reactor, the transport of heat, the conversion and transmission of power.
In embodiments, ONP Systems 202 may include one or more Marine Systems 212. In embodiments, the term “marine system” may be understood to encompass, except where context indicates otherwise, a system associated with the function of the unit as a marine vessel, including navigation, stability, structural integrity, and accommodation of crew.
In embodiments, ONP Systems 202 may include one or more Control Systems 214. In embodiments, the term “control system” may be understood to encompass, except where context indicates otherwise, a system of devices or set of devices (including enabled by various hardware, software, electrical, data, and communications systems, that manages, commands, directs or regulates the behavior of other device(s) or system(s) to achieve desired results. Control systems may include various combinations of local and remote control systems, human-operated control systems, machine-based control systems, feedback-based control systems, feed-forward control systems, autonomous control systems, and others.
In embodiments, ONP Systems 202 may include one or more Contingency Systems 216. In embodiments, the terms “contingency system” or “emergency system” may be understood to encompass, except where context indicates otherwise, a system on or interfacing with an ONP that can prevent, mitigate, or assist in recovery from accidents, which may include design-basis accidents (i.e., accidents that may occur within the normal operating activities of the ONP) and beyond-design-basis accidents and events, including both human initiated events (e.g.: terrorism or attacks), significant failure of ONP facilities, environmental events (e.g.: weather, seismic activity, and the like) and “acts of God.”
In embodiments, ONP Systems 202 may include one or more Accessory Systems 206. In embodiments, the term “accessory system” may be understood to encompass, except where context indicates otherwise, a system which, when included in or interfacing with an ONP unit, can tailor the unit to operating in different deployment scenarios and/or that can provide or enable an accessory function for the ONP (such as a function that can occur episodically like maintenance, refueling or repair that may involve moving items around the ONP). Accessories may be related to the plant functions, marine functions, and contingency functions, among others. For example, an accessory marine system could improve the stability of the foundation of a seafloor mounted ONP or can act as a breakwater depending on local wave conditions. An accessory plant system could provide an interface for transport of power/utility products or might use process heat to manufacture value-added industrial products local to the unit. An accessory system like a crane might be used to move units around during refueling or maintenance operations. These and many other accessory systems are encompassed in the present disclosure.
In embodiments, an ONP Unit Deployment may include one or more Associated Systems 208. In embodiments, the term “Associated system” may be understood to encompass, except where context indicates otherwise, a system interfacing with a single unit or a fleet of ONP units which performs a function related to the design, configuration, awareness, defense, operation, manufacturing, assembly, decommissioning of ONP units, and other associated contexts. In embodiments, this may include a system that performs a function that is not necessarily core to the operation of the ONP but that may involve interaction with an ONP, such as a weather prediction system, a tsunami or extreme-wave warning system, a smart grid system, an agricultural or industrial production system that uses power from the ONP, a desalination system, and many others.
In embodiments, an ONP Unit Deployment may include one or more Auxiliary Systems 218.
In embodiments, an ONP Unit Deployment may also include Associated Vessels and Facilities 220 that can be associated with the system but are not inextricable physical portions of it, e.g., tenders, crew transports, fuel transports, vehicles of defensive forces, supply depots, on-shore grid substations, manufacturing facilities and many more.
As also indicated in
A second compound configuration 524 is herein denoted the “ONP-M” configuration, where a nuclear module 526 can be grounded on the seafloor 526 and interfaced with an accessory unit 528, also preferably manufactured in a modular manner at a shipyard and towed to the service location. The ONP-M configuration 524 is typically suitable for water of moderate depth (for example, approximately 20-40 meters depth). A third compound configuration 530 is herein denoted the “ONP-S” configuration, where a floating nuclear module 532 can be interfaced with a floating accessory unit 534, also preferably manufactured in a modular manner at a shipyard and towed to the service location. The floating accessory unit 534 can be anchored to the seafloor 506 at its service site by tethers, e.g., tether 536. The ONP-S configuration 530 can be typically suitable for water of greater depth (for example, 60+ meters depth).
It will be clear that the categories of “simplex” and “compound” ONP configurations, and the particular examples shown herein, are illustrative only, and not restrictive of the range of ONP configurations in various embodiments.
Also herein, primary systems can be those performing functions definitive of the purpose of the ONP, e.g., generating steam from nuclear heat or generating electrical power from steam. Primary systems are closely aligned with integral systems. Auxiliary systems (typically instantiated in corresponding Auxiliary Modules 610), can be those that support the reliable operation of primary systems, e.g., by cooling, lubricating, powering, controlling, and monitoring primary systems.
The Nuclear Plant Module 604 can include a Containment Module 612 that can contain the nuclear reactor, a Fuel Module 614 that can perform fuel handling and spent-fuel storage functions, and one or more Auxiliary Modules 616.
Accessory Modules 618 can also include the Unit Modularization 600; these can include modularized systems for handling aspects of interaction with associated systems of ownership 620, implementation 622, physical environment 624, and consumers 626.
Unit Modularization can be responsive to at least two sets of criteria or constraints, which can be in aspects peculiar to the marine situation of an ONP and which may occasionally be in tension: (1) internal constraints on form and organization (e.g., it may be inherently advantageous to locate turbines and generators close together, or the Containment Module 612 and the Fuel Module 614), and (2) external constraints derived from the ONP's environment (e.g., physical, electrical fiscal). In various embodiments, the particular Modularization meets the foregoing criteria and others while maximizing shipyard manufacturability and minimizing cost.
Of note, modules and systems are not synonymous. Although in many cases a single system can be implemented in a single module, a system may extend across multiple modules or a single module may comprise more than one system, in whole or part. Moreover, modules can be combinable and nestable.
Modules of various types may be assembled, preferably but not necessarily or exclusively in a shipyard, to form an ONP unit 702 (with many possible variations as disclosed throughout). These module types can include skid modules (also referred to as Skids) 704, panel modules (also referred to as Panels) 706, block modules (also referred to as Blocks) 708, Megablock modules (also referred to as Megablocks) 710, and others. Modules can be assembled from other modules and from various categories of parts and materials; two notable part categories are components 712 and structural supports 714. Components 712 can be discrete units of machinery or structure that are typically produced by a particular manufacturer and delivered to the shipyard for incorporation into the ONP unit 702; a few exemplary components are vessels, pumps, sensors, computers, transformers, turbines, and generators. Structural supports 714 may be understood to encompass, except where context indicates otherwise, objects, systems or materials that can support a module, component, panel, skid, block, megablock, or other structural element, as by transferring load forces between one of the foregoing and the superstructure, hull, or frame of an ONP unit 702. In embodiments, modules may support other modules structurally; alternatively, or additionally, structural supports perform an independent structural function. The latter case is indicated by the arrow connecting structural supports 714 directly to blocks 708, i.e., structural supports may be incorporated in blocks without first being incorporated into an intermediate module. Similarly, components 712 may be incorporated in blocks without first being incorporated in an intermediate module. For simplicity, the fact that components and structural supports may be added directly to blocks or megablocks 710 or the ONP unit itself 702 is not explicitly indicated in
For simplicity, feedstocks such as sheet metal, steel plates, bar stock, coatings, and the like are not depicted in
In embodiments, an ONP 702 may include one or more skids 704. In embodiments, the term “skid” may be understood to encompass, except where context indicates otherwise, an open structural form on which one or more components 712 can be mounted and provided interface. The structure of the form can enable the transportation, handling, installing, and operating of the components. In embodiments, skid modules may be built at factories and transported to a shipyard for assembly into blocks or large components/equipment may be built into a skid at the shipyard.
In embodiments, an ONP 702 may include one or more panels 706. In embodiments, the term “panel module,” may be understood to encompass, except where context indicates otherwise, an open structural form consisting of flat or shaped metal panels onto which reinforcing supports, doors, walls, and fluid and utility routing can be installed. Panel modules are built at factories in shipyards called panel shops. A panel module may also be used for an externally facing section of the hull; such as a bottom panel, shell panel, deck panel, or bulkhead panel. In embodiments, the term “bulkhead panel” may be understood to encompass, except where context indicates otherwise, a panel that forms a gas impermeable and/or fluid-tight barrier.
In embodiments, an ONP 702 may include one or more Blocks 708. In embodiments, the term “Block module,” may be understood to encompass, except where context indicates otherwise, a closed structural form assembled from Panel modules, Skid modules, structural supports, and components in a factory at a shipyard and then relocated to a drydock for further assembly into the final ONP Unit. The Block module may or may not have one or more of its edges acting as the hull of a unit.
In embodiments, an ONP 702 may include one or more Megablocks 710. In embodiments, the term “mega-block module” may be understood to encompass, except where context indicates otherwise, a closed structural form assembled from multiple Block modules, such as joined in a dry-dock. Megablock modules may be suitable for transport between shipyards; which may help distribute the construction work, such as between a variety of shipyards. In embodiments, Megablocks may be skidded or floated in and out of drydock.
In a typical modular manufacturing flow, according to embodiments of the present disclosure, modules of lesser size can be lifted by cranes or otherwise approximated by shipyard facilities to enable them to be joined into large modules. Ultimately, the joining of Megablocks (and, potentially, modules of lesser scope) can produce a finished ONP Unit 702. The Blocks 708 and Megablocks 710 that can be handled by routine shipyard facilities can greatly exceed in size any prefabricated units that can be economically moved overland, e.g., in the construction of a terrestrial nuclear power plant: thus, the modularization of ONP manufacturing flow in a manner that enables assembly to occur at an existing or dedicated shipyard facility can enable the realization of advantages over the prior art. One notable advantage is standardization of modules and of methods for their creation and assembly into larger modules; with shipyard techniques, modules can be relatively large and therefore few in both type (e.g., the four sub-ONP module types depicted in
Typically, two or more Blocks and Megablocks can be joined to form a completed ONP, often with the addition of some lower-level modules, components, and materials as well.
In embodiments, an ONP unit may include a containment vessel (CV) for containing a nuclear reactor. The CV may be a pressure-vessel-type containment vessel that contains the reactor under pressure that exceeds atmospheric pressure during a contingency, such as the breach of a pressurized system within the containment.
Pressure vessel-type containment vessels of various shapes (e.g., spherical, cylindrical, cylinder capped with hemispheres) may be used in an ONP unit. In embodiments, there are certain advantages of spherical containment vessels, including that spherical containment vessels minimize containment mass and volume for a given design pressure, that spherical containment vessels have been used in licensed nuclear power plants, and that spherical containment vessels have favorable dimensions for reducing the overall volume of the Nuclear Systems Block (Block 114 in
The many embodiments of the present disclosure include transferring the weight of a CV or of another massive vessel to the primary frame of an ONP and thence to the ONP's environment in a manner that can be appropriate to a marine structure. Systems and methods for CV support in an ONP should entail minimal mass, volume, and cost. Because constraints on mass and volume apply in the marine architectural context that do not apply in to terrestrial nuclear power plants, acceptable direct cost of CV support may be higher for an ONP than a terrestrial nuclear power plant. Direct costs, if higher for a CV of given size, can be more than offset by the advantages enabled by other aspects of an appropriate CV support system.
In embodiments, a cellular lattice (e.g., lattice 1802) may be welded, such as from a series of metal (e.g., steel) plates. Welding may be accomplished by a special purpose welding robot that is configured to be disposed within a cell of the cellular lattice and configured with one or more robotic arms or similar facilities for undertaking welds on the interior angles of the cells. For example, a robot with six robotic arms, each having a welding tool, may be configured to be disposed in the interior of a hexagonal cellular lattice to support rapid assembly of the support lattice.

The present disclosure further provides that nuclear power has been shown to be the most rapidly deployable and reliable clean energy source available to humankind. New plants can accelerate decarbonization of the electric power grid, drive economic growth, deliver new jobs, and provide a vital opportunity for industrial exports. However, significant delays and increased costs have arisen from stagnant approaches to project management, construction methods and decommissioning. To pioneer industry innovation and elevate economic opportunities in nuclear fission, we can revitalize and improve these processes. This collaborative project proposes a disruptive, cross-industry approach to achieve major cost reductions, improve asset integrity, and develop the UK supply chain for new capabilities.
The present disclosure includes applying shipyard manufacturing methods to nuclear plant construction. By fabricating code-compliant nuclear plant components and combining them into modules in a controlled factory setting, vast improvements in scheduling, cost reduction, asset integrity and quality control can be produced. In addition, it can be shown that there are significant benefits for decommissioning that arise from utilizing a float-out NPP design, which allows for the possibility of dismantling and recycling at the end of life. Successful execution can stimulate cross-industry knowledge transfer, develop the supply chain, and open new revenue opportunities.
The approach aims to utilize shipyard construction to build a NPP as a complete float-out unit in a specially equipped shipyard and tow it to customer sites for onshore or shallow water installation. This can allow a single build site to deliver to any customer site with proximity to seas or waterways. Applying shipyard manufacturing to nuclear construction can have the potential to transform the value proposition for nuclear power. Shipyards can achieve world-class productivity through block construction, where modules can be manufactured and outfitted in assembly-line production. The blocks can then be assembled in a dry-dock to produce the final vessel. Fabricating nuclear components into modules in a controlled factory setting can be shown to allow for improvements in scheduling, cost, asset integrity, and quality control. Specialized techniques and equipment, which can be expensive or impractical for field use, can be made possible by outfitting a shipyard facility specifically for nuclear builds. Examples of the present disclosure include robotic manipulation, automated welding, coating, testing, and advanced joining such as laser or electron beam welding. The present disclosure envisions a high quality standardized plant design that can be enabled by single site build methodology. Benefits can also arise for decommissioning by enabling dismantling and recycling by towing the retired plant to a breaking yard equipped for this purpose. The NPP can be designed with this in mind to ensure that dismantling can be performed in a cost-effective manner. This is in contrast to existing NPPs which must be demolished in-place at end of life and where design for dismantling is not a high priority.
Aspects of the present disclosure include deployment of existing technology and leveraging advanced manufacturing capabilities to ensure maximum competitiveness in a global market. Examples include a reactor plant design optimized for the shipyard constructed power plant, a set of fabrication process, a quality assurance program satisfying regulatory requirements, and a demonstrator build to prove these developments in practice. In the many examples, one focus of this project is >1000 MWe light water reactors (LWR), but can also be applicable to advanced and small modular reactors (SMRs). The present disclosure includes viable methods of reducing the build cost of new nuclear plants to an extent that can create a step change in the ability to deliver electrical power and process heat to a significant fraction of the globe.
The design of the containment vessel (CV) can require expertise in marine engineering, pressure vessel engineering, and nuclear engineering. The CV can be designed in parallel with the reactor plant and ship structure to produce an optimal design. Categories of design codes and areas of applicability are illustrated in
In many aspects of the present disclosure, the Containment Vessel (CV) can include the following attractive attributes: CVs are required for all LWR designs including Boiling and Pressurized water reactors. The size and amount of erected steel involved can make it a useful demonstration of shipyard fabrication and erection.
A CV is a large pressure vessel built to nuclear design codes and as such it is an inherently multidisciplinary project. The skills and techniques required to build it will be applicable for constructing much of the rest of the project.
CV re-design as a barge-deliverable structure can be shown to represent a ready opportunity for a design for manufacture exercise. The size and form factor of the CV can be a significant driver of the size and height of the overall offshore nuclear plant structure which can make it an attractive item for design optimization with significant cost implications beyond the item itself.
In many examples, the outputs of this project can be shown to be at least a reactor plant design optimized for the shipyard constructed power plant, a set of fabrication process, a quality assurance program satisfying regulatory requirements, and a demonstrator build to prove these developments in practice. In one example, the focus of this project can be a >1000 MWe light water reactors (LWR). One results can be shown to include a viable method of reducing the build cost of new nuclear plants to an extent which will create a step change in the ability to deliver electrical power and process heat to a significant fraction of the globe.
In embodiments, the present methods and systems include a large boiling water reactor (BWR) based unit. The present methods and systems include a deployment model for the shipyard manufacture and marine delivery of nuclear power plants to significantly increase the attractiveness of nuclear project investment. The deployment model can be shown to reduce costs, speed delivery, reduce key project risks, enhance passive safety, and expand siting options for large-scale and small modular reactors (SMRs) based nuclear power plants.
In embodiments and with reference to
In embodiments, it can be shown that the deployment model may attack the fundamental drivers of nuclear costs and schedule overruns. These drivers include shipyards use block construction, a method involving the assembly of prefabricated sections; parallel production of modules to greatly reduce schedule risk; higher productivity and elimination of concrete radically reduces cost; shipyard production processes enable high levels of quality and inspection with much lower cost and impact on schedule; and large modules, weighing several thousand tonnes, can be manufactured at different shipyards, fully outfitted, and transported to the completion shipyard for final assembly.
In embodiments, there is adequate deep water access for delivery of the barge to one of the currently designated sites. In embodiments, barge design may be more compact than existing ABWR designs enabling siting flexibility within the permitted site envelope. In embodiments, barge delivery of the nuclear plants largely eliminates construction impact at the site
It will be appreciated in light of the disclosure that shipyard-based construction enables the possibility to streamline the regulatory oversight process over time. As such, regulators may see the same shipyard, same team, same process, same products, etc. This, in turn, may lead to easier regulatory approvals from one country to the next; reduces. regulatory cost over time; enables use of much more modern technology in regulatory review.
In embodiments, the methods and systems disclosed herein can enable vastly more opportunities to site plants. Importantly, there is no need to purchase the rights from an existing owner or spend the same amount of upfront capital to secure site control. The methods and systems may enable potentially the ability to leverage coastal transmission connections from existing or retired power plants (inclusive of nuclear, coal, gas, and wind). In embodiments, there is potential to co-locate with offshore wind project and leverage their transmission capacity. It will be appreciated in light of the disclosure that shipyard-based construction enables far better control of scheduling and cost risks. To that end, there can be faster overall delivery as factories and shipyards are designed to operate around tight schedules and make every effort to avoid delays that would lower overall throughput. Compared with stick-built construction, there can be much earlier detection of defects and faults. There may be tight tracking of parts and status with infrared barcodes throughout facility and possibly the broader supply chain. There may be substantially greater opportunity to reduce sequential delay linkages (delay will be longest individual delay instead of the sum of all individual delays). In embodiments, there can be a reduction in the risk of schedule exceedance directly translates to reduction in the risk of budget exceedance (which, can dramatically reducing interest payments). This deployment can be shown to avoid the quagmire of concurrent engineering and construction. It dramatically reduces the possibility of change orders and thereby the associated engineering and vendor expenses.
In embodiments, various system and methods can be configured to cause very little public disturbance. Beyond a few kilometers, it will be difficult to see the plant. In embodiments, there may be little site remediation required, especially relative to a terrestrial plant.
In embodiments, various system and methods can be configured to be one generation decisions such that the ability to provide clean energy for a pre-determined and relatively short timeframe changes the dimension of the decision for local populations.
In embodiments, various system and methods can be configured so spent fuel can be transported away from site and decommissioned in a nuclear qualified shipyard, much like nuclear-powered submarine or aircraft carrier. Decommissioning may be performed in the original shipyard or a dedicated, in-country shipyard, depending on host preference. In embodiments, various system and methods can be configured to require decommissioning and it is dramatically lower in cost as no materials have the potential to absorb radioactive materials.
In embodiments, various system and methods can be configured to reduces costs, speed delivery, reduce key project risks, enhance passive safety, and expand siting options for large-scale and SMR based nuclear power plants. It can be shown that such project costs may be reduced by 50% and dramatically speed deployment.
In embodiments, various system and methods can be configured for shipyard manufacturing, marine delivery of SMR plants for customer such as into the Great Lake such as Lake Huron and coastal plant locations elsewhere in the world. These plants may be bottom mounted, offshore sited, and GW-scale plants.
In embodiments, various system and methods can be configured so that all units will be transported to location via tugs or heavy lift ships. The vessels that prepare the deployment location are also within the scope of the product family. All units must be sufficiently protected against local environmental conditions. Breakwaters will mitigate tsunami, rogue wave, and ship collisions for near shore mounted units while mooring systems and floating barriers will protect units further out to sea.
In embodiments and with reference to
In embodiments, piping and equipment layout can be configured to support re-packaging of terrestrial plant footprint into offshore structure. Total building volume will be approximately similar, but overall shape will change. Elevations of Vessels and Piping will be kept as similar as possible to prevent unnecessary re-design of pumps, piping, and instrumentation.
In embodiments, various system and methods can be configured to include generally any reactor type can be modified to support the requirements for this product type, the following reactors are considered to be the most likely candidates due to their current market availability and licensed or license in-progress status: Mitsubishi Heavy Industries APWR, 4 loop PWR, 1; 700 MWe net; Korea Electric Power Corporation APR-1400, 2 loop PWR, 1; 400 MWe net; Korea Electric Power Corporation APR+, 2 loop PWR, 1; 500 MWe net; Toshiba/Westinghouse AP1000, 2 loop PWR, 1; 100 MWe net; General Electric/Hitachi ABWR, BWR, 10 Internal Pumps, 1; 350 MWe net; General Electric/Hitachi ESWR, BWR, Natural Circulation, 1; 500 MWe net.
It will be appreciated in light of the disclosure that some of these designs offer advantages relative to their peers for an offshore deployment, especially the designs such as AP1000 and ESBWR which utilize “passive” cooling of the core. This allows for relative independence from offsite electrical power during an accident scenario. Additionally, the reduced number of pumps and safety related systems required for these plants would simplify maintenance and construction costs. That said, the importance of availability of design and engineering support from the nuclear vendor outweighs the relative engineering merits of each plant type and all designs are considered feasible and acceptable for this product type. For the initial product deployments, units incorporating a single or twin reactor plants may be produced depending on customer requirements. Twin units may be deployed as duplicate plants being housed in a single offshore structure, or each reactor unit may be delivered to site independently, sharing support services as practical.
In embodiments, this family of products includes free floating or tethered units which allow deployment to sites with deeper waters or areas where other hazards such as seismic or tsunami considerations make a bottom mounted unit impractical. In this deployment scenario, some wave motion will be transmitted to the plant and additional design work must be performed to support this. Refueling is a particular area where these motions may require development and modifications of fuel
In embodiments, various system and methods can be configured so that requirements for the nuclear and power generation system will be defined on the basis of an existing reactor design modified for installation in the hull structure. Design data from the nuclear plant which will influence the design of the hull structure includes equipment masses, centers of gravity, required structural stiffness, containment geometry, spent fuel storage requirements, cooling water for normal operation, cooling water for accident or faulted operation, export power cable characteristics, control rooms, personnel accommodation, and protection from external aircraft or ship impact.
Additional requirements for the hull structure are defined in terms of its life cycle phases, including construction, float-out to site, installation on seabed or connection to anchors, operation, removal and decommissioning. In each phase, the structure must support the payload with displacements and accelerations consistent with the requirements of the nuclear and power generation systems, resist seismic, tsunami, wind, wave, current and gravity loads. Adequate allowances for corrosion and fatigue loads will be made to achieve desired equipment life spans in the marine environment.
In embodiments, various system and methods can be configured so the structures may be designed with modular construction in mind, minimizing, to the extent practical, service (communications equipment, power, piping) connections across likely block boundaries. The structure may be characterized for marine analysis in term of its mass and mass distribution, external geometry and structural stiffness at the seabed interface if bottom founded. Maximum lateral and rotational motion requirements will be defined by the nuclear and power system designers.
In embodiments, various system and methods can be configured so the platforms can be built at shipyard(s) with high level offshore experience, using state of the art offshore fabrication methods such as modular construction. Higher quality and reduced construction time can be achieved compared to conventional on site fabrication. In embodiments, small steel blocks (up to about 250 tons) will be fabricated in special steel workshops. In embodiments, painting will be done in controlled painting workshops. In embodiments, the small blocks will be assembled to large sections (500 to 2500 tons) and as far as possible outfitted with equipment and systems (pumps, piping, etc.). In embodiments, the majority of work may be done in highly controlled and efficient workshop conditions. Large blocks will be placed in the dry dock, at four building locations, making four mega blocks (weight from 10; 000 up to 40; 000 tons). In embodiments, the work may be spread around four locations, permitting more manhours in less time, avoiding clashing work and inspection and creating flexibility to man up individual activities. Upon completion, the four megablocks may be married into one complete platform. In embodiments, the completed platform can float out of building dock to completion quay for final completion commissioning and testing.
The associated systems 3104, 3106, 3108, 3110 interact with the Unit Configuration via Interface Systems 3122, 3124, 3126, 3128. In embodiments, the terms “interface,” “interface system,” and “interfacing system” may be understood to encompass, except where context indicates otherwise, one or more systems, services, components, processes, or the like that facilitate interaction or interconnection of systems within an MNP or between one or more systems of the MNP with a system that is external to the MNP, or between the MNP and associated systems, or between systems associated with an MNP.

In embodiments, MNP Systems 3202 may include one or more Contingency Systems 3218. In embodiments, the terms “contingency system” or “emergency system” may be understood to encompass, except where context indicates otherwise, a system on or interfacing with an MNP that prevents, mitigates, or assists in recovery from accidents, which may include design-basis accidents (accidents that may occur within the normal operating activities of the MNP) and beyond-design-basis accidents and events, including both human initiated events (terrorism or attacks), significant failure of MNP facilities, environmental events (weather, seismic activity, and the like) and “acts of God.”
In embodiments, MNP Systems 3202 may include one or more Auxiliary Systems 3220. In embodiments, the term “accessory system” may be understood to encompass, except where context indicates otherwise, a system which, when included in or interfacing with an MNP unit, tailors the unit to operating in different deployment scenarios and/or that provides or enables an accessory function for the MNP (such as a function occurring episodically like maintenance, refueling or repair that may involve moving items around the MNP). Accessories may be related to the plant functions, marine functions, and contingency functions, among others. For example, an accessory marine system could improve the stability of the foundation of a seafloor mounted MNP or act as a breakwater depending on local wave conditions. An accessory plant system could provide an interface for transport of power/utility products or might use process heat to manufacture value-added industrial products local to the unit. An accessory system like a crane might be used to move units around during refueling or maintenance operations. These and many other accessory systems are encompassed herein.
In embodiments, an MNP system may include one or more Associated Systems 3208. In embodiments, the term “associated system” may be understood to encompass, except where context indicates otherwise, a system interfacing with a single unit or a fleet of MNP units which performs a function related to the design, configuration, awareness, defense, operation, manufacturing, assembly, and/or decommissioning of MNP units. In embodiments, this may include a system that performs a function that is not necessarily core to the operation of the MNP but that may involve interaction with an MNP, such as a weather prediction system, a tsunami or extreme-wave warning system, a smart grid system, an agricultural or industrial production system that uses power from the MNP, a desalination system, and many others.
In embodiments, an MNP system may also comprise Associated Vessels and Facilities 3222 that are associated with the system but are not inextricable physical portions of it, e.g., tenders, crew transports, fuel transports, vehicles of defensive forces, supply depots, on-shore grid substations, and many more.
As also indicated in
Also herein, primary systems are those performing functions definitive of the purpose of the MNP, e.g., generating steam from nuclear heat or generating electrical power from steam; primary systems are closely aligned with integral systems. Auxiliary systems (typically instantiated in one or more corresponding Auxiliary Modules, e.g., Auxiliary Module 3234) are those that typically support the reliable operation of primary systems, e.g., by cooling, lubricating, powering, controlling, and monitoring primary systems, and the like.
The Nuclear Plant Module 3230 comprises at least one Reactor Containment Module 3236, each of which contains a nuclear reactor, a Fuel Module 3238 that performs fuel handling functions, at least one Auxiliary Module 3240, a Control Room Module 3242, and a Radwaste Module 3244 that handles spent nuclear fuel and other radioactive waste. Typically, the number of Reactor Containment Modules 3236 is equal to the number of Turbogenerator-Condenser Modules 3232.
Unit Modularization is preferably responsive to at least two sets of criteria, requirements, or constraints (collectively referred to simply as “constraints”), which are in aspects peculiar to the marine situation of an MNP and which may occasionally be in tension: (1) internal constraints on form and organization (e.g., it may be inherently advantageous to locate turbines and generators close together, or to have a direct interface between the Reactor Containment Module 3236 and the Fuel Module 3238), and (2) external constraints, such as those derived from the MNP's environment (e.g., physical, electrical, operational, fiscal, or the like). In various embodiments, a particular Modularization may be configured to satisfy the foregoing criteria and others while taking advantage of shipyard assembly and manufacturability.
Of note, “modules” and “systems” are not synonymous. Although in many cases a single system may be implemented in a single module, a system may extend across multiple modules, or a single module may comprise more than one system, in whole or part. Moreover, in embodiments modules are combinable and nestable.
It will be clear that the categories of “simplex” and “compound” MNP configurations, and the particular examples shown herein, are illustrative only, and not restrictive of the range of MNP configurations in various embodiments.
Some material inputs to the configuration 3400 arrive from a secured receiving facility 3406, which handles the arrival of nuclear fuel for the nuclear power plant 3402; from a marine environment 3404, which, if an ocean, is a source of water as a feedstock, water as a coolant, and compounds in solution (e.g., CO2, salt); and from a raw industrial materials receiving facility 3408. Material and energy outputs of the configuration 3400 are handled, before transfer out of the configuration 3400, by a dry cask storage facility 3410, an electrical substation 3412, a products storage and distribution facility 3414, and fossil fuel reservoirs 3416. Materials are altered in form, typically in a value-adding manner, in a number of process facilities, including a desalination plant 3418, an electrolysis plant 3420 producing H2 and O2 from H2O, an industrial process plant 3422, an agricultural facility 3424, a fuel production facility 3426, and a petrochemical process plant 3427. Some or all of the foregoing plants and facilities except inherently stationary resources (e.g., natural fossil fuel reservoirs) are, in various embodiments, produced and delivered to the deployment 3400 as MP units, realizing advantages including those enumerated hereinabove for MP units. Various embodiments omit one or more of the facilities comprised by illustrative configuration 3400 and include facilities not comprised by configuration 3400.
Materials that flow or are transferred between elements of the configuration 3400 include fresh nuclear fuel 3428; cooled spent nuclear fuel 3430; coolant water 3432; electrical power 3434 for distribution to consumers; electrical power 3436 for use by the desalination plan 3418; desalinated water 3438 for use by the electrolysis plant 3420; desalinated water 3440 for use by the industrial process plant 3422; desalinated water 3442 for use by the agricultural facility 3424; raw industrial materials (e.g., feedstocks) 3444 for use by the industrial process plant 3422; fertilizer 3446 for use by the agricultural facility 3424; industrial products 3448 for handling by the storage and distribution facility 3414; agricultural products 3447 for handling by the storage and distribution facility 3414; desalinated water 3450 for handling by the storage and distribution facility 3414; electrical power and process heat 3452 for use by the industrial process plant 3422, agricultural facility 3424, and fuel production facility 3426; raw synthetic fuels 3427 from the production facility 3426 for processing by the petrochemical plant 3424; process heat and steam 3454 for use in extraction from the fossil fuel reservoirs 3416; raw fossil fuel 3456 for processing by the petrochemical process plant 3426, petrochemical outputs 3458 for handling by the storage and distribution facility 3414, and electrolysis gases 3460 (e.g., H2, O2) for use by the industrial process plant 3422, and electrolysis gases 3462 for handling by the storage and distribution facility 3414.
Of note, in embodiments the storage and distribution facility 3414 enables the export of industrial and/or agricultural products from the deployment 3400; the secured receiving facility 3406 has safeguards such as secure tracking and reporting to appropriate regulatory authorities as fuel is received, as well as a secure physical fuel-transfer connection to the power plant 3402; H2 from the electrolysis plant 3420 can also be an input to the petrochemical process plant 3426 (transfer connection not depicted in
Various MP units, including the nuclear unit 3402, may be located in a littoral, near-shore, or off-shore manner realizing environmental and social advantages by minimizing disruption of landmass and coastal environments and human settlement patterns. The deployment 3400 can serve countries that have growing energy, water and transportation fuel needs, but do not wish or cannot afford to develop the massively expensive infrastructure that is required to produce them indigenously. For various embodiments, initial installation of can be rapid, as MPs are transported from shipyards to site, with minimal site preparation required compared to traditional terrestrial power and water projects. If a worldwide fleet of MPs is available, production could be initiated within months as compared to years or decades for conventional development approaches. Capacity and capabilities of the deployment 3400 or other embodiments can be modified flexibly during the lifetime of the project by adding or subtracting MPs. The customer does not have to commit to a 60-80 year project, and the host country does not need to own the infrastructure. Given a nuclear power source 3402, desalinated water and synthetic fuels production occurs with essentially zero direct CO2 emissions.
Moreover, various industrial and agricultural processes can realize advantages by integration with the nuclear plant 3402 in deployment 3400, since closer proximity of facilities to the primary energy source 3402 and to each other reduces all losses and costs associated with transport of electricity, heat, water, gasses, industrial material, products, and the like. Pipelines, which tend to be expensive and vulnerable, are reduced by proximity to minimal lengths, enabling the more efficient transfer of liquids (e.g., desalinated water for agriculture and other processes) and gasses (e.g., H2, notoriously difficult to contain) and the more economic exploitation of heat (the primary energetic output of a nuclear power plant) in, e.g., industrial, agricultural, production, and fuel extraction processes. Transmission losses for electrical power to points of use are also reduced, and shorter electrical transmission lines connecting the power plant 3402 to various facilities of the deployment 3400 are less costly and more reliable than long-haul lines. Security and defense are advantageously realized in deployment 3400 by tasking defensive systems (e.g., barriers, surveillance and sensor gear, oversight personnel, response teams, drones) with the security of a relatively unified and restricted area, i.e., that occupied by deployment 3400, in contrast to securing a number of disparately located facilities connected by relatively long, costly, and vulnerable pipelines, transport routes, and power lines. Environmental benefits are also realized, e.g., by decreased land consumption for pipelines, power lines, and the like; by the increased feasibility of energy-intensive, environmentally beneficial processes such as manufacture of synthetic fuel from atmospheric carbon, dissolved oceanic carbon, fossil-fuel feedstocks, and/or H2 from electrolysis; by increased feasibility of carbon sequestration from industrial processes and fuel synthesis; and the like.
In an illustrative use case, a coastal industrial enterprise of foreseeably temporary nature (e.g., mining of a finite resource) can realize advantages from the deployment of MP units in an agro-industrial complex, as these can be deployed rapidly and economically un-deployed by similar means at the end of project lifetime, again with potential realization of environmental benefits. These and other advantages are realized by various embodiments. Comprising of MP units by the proposed agro-industrial complex is unique and distinctive from all prior proposals for nuclear-powered complexes, e.g., Nuclear Energy Centers: Industrial and Agro-Industrial Complexes, Oak Ridge National Laboratory ORNL-4290, November 1968, the teaching of which is incorporated herein by reference.
In an example of an energy-intensive industrial process benefiting from proximate access to the heat output of the nuclear plant 3402, magnesite (MgCO2) is converted to magnesium oxide (MO) and CO2 by the addition of heat, the CO2 being persistently sequestered in a carbon capture-and-storage process that pumps the CO2 into a saline aquifer at high enough pressure to make the CO2 into a supercritical fluid that dissolves in the saline. Such sequestration will be more economically feasible where the energy inputs to magnesite conversion and sequestration are more economically obtained, as in the deployment 3400.
In another example, the Bayer processing of bauxite to produce aluminum is well-known as an electricity-intensive process and would benefit by proximity to the nuclear plant 3402.
In another example, process steam 3454 can be used to mobilize high-viscosity fossil fuels (e.g., bitumen) in an unconventional reservoir 3416 or a conventional reservoir depleted of readily extractable fossil fuel.
In another example, useful materials may be extracted from seawater as a byproduct of desalination 3418, electrolysis 3420, and additional processes. For example, carbonates can be extracted from seawater and converted to oxides for cement manufacture. Also, magnesium is present as a soluble salt in seawater (˜1.3×10-3 kg/liter Mg2+ ions, associated with chloride and sulphate ions) and can be produced as a suitable industrial compound, e.g., magnesia. Also, sea salts (primarily sodium chloride) are a marketable byproduct of desalination with appropriate quality controls.
Numerous other examples could be adduced of energy-intensive processes that would benefit by integration in a deployment 3400 or other embodiments, including oxygen liquefaction from air, electric steel and iron production, ferromanganese refinement, and more. All such processes are contemplated.
The MNPP-D,B,M Unit 3502, as its “PP” designation indicates, comprises a Power Plant as well as a nuclear source of energy; herein, a Power Plant comprises the machinery for converting at least part of the thermal output of a nuclear energy source to a different form, e.g., steam, electricity, or other. The MNPP-D,B,M Unit 3502 also comprises one or more SMRs and is preferably delivered, in partially or wholly complete form, by flotation to the Coastal Interfaces unit 3506 and is housed therein.
A basin (“B”)-type Coastal Interfaces unit 3506 comprises an originally water-filled channel or slot excavated into a coastline and into which the MNPP-D,B,M Unit 3502 and/or other manufactured plant units may be delivered by barge. A dock (“D”)-type Coastal Interface unit 3506 comprises a structure standing in water, though relatively close to shore, where the MNPP-D Unit and/or other manufactured plant units may be delivered by barge and housed. The stabilizing physical basis or bulk of typical dock comprises cessions that are floated into place and grounded (e.g., filled with water and/or rocky material); a dock or other Coastal Interfaces Unit also typically comprises associated subsystems such as a low-voltage bus 3512, a fluids manifold 3514, and a rail system 3516 for transfer of waste casks and other heavy objects. The nature of basins and docks will be further clarified herein with reference to several Figures. Herein, a unit denoted “D,B” may, in embodiments, be housed by either a Dock-style or Basin-style Coastal Interfaces unit.
The Associated Coastal Facilities 3508 are located on land comprise an electrical switchyard 3518, a tank yard 3520, and a dry cask yard 3522 for the storage of cool nuclear waste. Various embodiments comprise facilities for control and auxiliary and/or contingency systems (not depicted in
The Coastal Interfaces unit 3506 preferably enables exchanges of energy, fluids, and rail-carried objects not only between the Manufactured Plant units 3502, 3504 and the Associated Coastal Facilities 3508 but among Manufactured Plant units 3502, 3504 and/or among portions of the Associated Coastal Facilities 3508.
Although the Unit Configuration 3500 comprises only a single Manufactured Nuclear Power Plant (MNPP), various embodiments comprise multiple MNPPs. Also, as shall be further clarified with reference to subsequent Figures herein, various embodiments comprise separately manufactured and delivered Nuclear Plants (NPs, nuclear energy-producing units) and Power Plants (PPs, energy-conversion units), in contrast to the MNPP-D,B, Unit 3502, which integrates an NP and a PP.
As will also be made clear with reference to other Figures herein, the Unit Configuration 3500 also preferably comprises a protective barrier structure (not depicted in
The Unit Configuration 3600 resembles Unit Configuration 3500 of
The Unit Configuration 3700 resembles Unit Configuration 3500 of
In a typical sequence of operations, a Dock- or Basin-type Coastal Interfaces facility 3812 is constructed adjacent to a Decommissioning Site 3814 and an MNP-D,B unit 3802 is brought to the site with the other Units 3804, 3806, 3808, 3810 required for the decommissioning process. Preferably the MNP-D,B unit is of a type that supplies steam appropriate for the Power Plant 3818 of the Decommissioning Site 3814; for example, if the Steam Source 3820 is fossil-fueled, it will typically have produced high-temperature steam and a gas-cooled reactor would be most appropriate in the MNP-D,B Unit 3802. In another example, if the Steam Source 3820 is a boiling-water reactor, then a boiling-water reactor would be most appropriate in the MNP-D,B Unit 3802.
During an early stage of a decommissioning process, the original Steam Source 3820 is turned off and steam supply to the Power Plan 3818 from the MNP-D,B commences. If the Steam Source 3820 is fossil-fueled, it is relatively straightforward to disassemble and remove its components, if desired. If the Steam Source 3820 is nuclear, then it is necessary to deal with nuclear waste that has accumulated onsite during the plant lifetime. In the latter case, spent fuel from the Steam Source 3820 is conveyed to the MFPP-D,B 3806 by the Cask/Rail Transfer system 3830 and reprocessed, yielding usable fuel for the MNP-D,B Unit 3802 and a reduced quantity of high-level waste to be removed in dry casks to a long-term repository. The MRWPP-D,B 3808 deals with various forms of non-fuel nuclear waste produced by the original nuclear plant: e.g., it filters and dewaters liquid low-level waste, discharging the purified water portion to the environment and retaining a greatly reduced volume of concentrated waste to be removed in dry casks to a long-term repository. Although a dedicated non-manufactured radioactive-waste processing plant could be built on the Decommissioning Site 3814, the use of an MRWPP-D,B 3808 is advantageous because it can be used on multiple decommissioning projects before becoming unacceptably radioactive and requiring decommissioning itself, in contrast to a custom-built onsite plant, which can only be used once and is not practical to relocate.
The MDCP-D,B Unit 3810 is analogous to a dumpster system that can be used to collect, compact, and transport large amounts of non-liquid low-level contaminated structural material from the Decommissioning Site 3814, e.g., fill, etc. The MDCP-D,B, Unit 3810 typically comprises atmospheric control systems, multiple silos for different waste types, and various other subsystems for monitoring and controlling the waste.
The on-shore facilities of the deployment 4000 are sheltered by a defensive perimeter 4040 that may comprise various barriers, devices, personnel, drones, and the like to defend the deployment 4000; additional defensive measures may be comprised by the deployment 4000 to defend against aerial and marine threats. Whether or not named or depicted herein, such defensive arrangements are comprised by all embodiments discussed herein, as well as by various other embodiments.
An advantage of deployment 4000, as of various other embodiments, some discussed herein, is that all components delivered as Manufactured Plant Units may be removed as they were delivered, by flotation, whether for decommissioning at a specialized facility or deployment at a different location, and one or more replacement Units may be installed at the deployment. Mobility and modularity thus are features of the nuclear power source as a whole, as of other Manufactured Plant Units comprised by the deployment: moreover, SMRs are preferably and typically small enough to be removed from the MNP, redeployed, decommissioned remotely, and/or replaced in a manner analogous to the MNP itself. Thus, advantages are obtained from modularity and mobility both at the deployment scale and at the scale of the individual small modular reactor.

If the MNP-D 4428 is installed in the dock 4408 in the orientation shown in
An advantage of the deployment 4400, and of various other deployments in which a larger number of MPs are deployed rather than a smaller number combining several functions in each, is that smaller MPs tend to allow a larger variety of shipyards to participate, which in turn encourages diversification of supply chain, reduces construction time, and makes feasible access to a wider range of MP delivery sites.
That portion of the basin 4510 which houses the nuclear-materials portion of the MNP-B 4528 is overarched lengthwise by a portion 4540 of an impact shield (depicted in cross-section), this lengthwise portion 4540 of the impact shield being open at both ends. A rail transfer system 4542 connects the auxiliary unit 4532 of the MNP-D 4528 to an administration and security facility 4544 and thence to a cask yard 4546. A tank yard 4546 houses fluids such purified water for reactor operations and low-level liquid radioactive waste. The two power plants 4524, 4526 exchange steam with the NP 1530 via pipes, e.g., pipe 4548) supported by pipe bridges (e.g., pipe bridge 4550), and the resulting electricity distributed to a grid or other consumers via switchyards 4552, 4554. Preferably, one power plant 4524 exchanges steam with six (6) SMRs in the NP 4530, and the other power plant 4526 exchanges steam with the other six (6) SMRs in the NP 4530. Coolant water is collected from the environmental water body via inlets and outlets not depicted in
Fluids are also conveyed between the tank yard 4546 and the auxiliary systems unit 4532 of the MNP-B 4528 by piping 4558. The impact shield around the NP 4430 is completed by two endcap shields (e.g., shield 4560) comprised by the MNP-B 4528. The rail transfer system 4542 enables exchange of nuclear and other materials (e.g., dry casks of cooled spent nuclear fuel, SMRs) between the onshore facilities and the auxiliary module 4532; in other embodiments, the orientation of the MNP-B 4528 is reversed, in which case casks, SMRs, and other loads are exchanged by flotation with the seaward end of the MNP-B 4528.
In an example, the deployment 4500 is advantageous over that of

The elements described and depicted herein, including in flow charts and block diagrams throughout the Figures, imply logical boundaries between the elements. However, according to software or hardware engineering practices, the depicted elements and the functions thereof may be implemented on machines through computer executable transitory and/or non-transitory media having a processor capable of executing program instructions stored thereon as a monolithic software structure, as standalone software modules, or as modules that employ external routines, code, services, and so forth, or any combination of these, and all such implementations may be within the scope of the present disclosure. Examples of such machines may include, but may not be limited to, personal digital assistants, laptops, personal computers, mobile phones, other handheld computing devices, medical equipment, wired or wireless communication devices, transducers, chips, calculators, satellites, tablet PCs, electronic books, gadgets, electronic devices, devices having artificial intelligence, computing devices, networking equipment, servers, routers, and the like. Furthermore, the elements depicted in the flow chart and block diagrams or any other logical component may be implemented on a machine capable of executing program instructions. Thus, while the foregoing drawings and descriptions set forth functional aspects of the disclosed systems, no particular arrangement of software for implementing these functional aspects should be inferred from these descriptions unless explicitly stated or otherwise clear from the context. Similarly, it will be appreciated that the various steps identified and described above may be varied, and that the order of steps may be adapted to particular applications of the techniques disclosed herein. All such variations and modifications are intended to fall within the scope of this disclosure. As such, the depiction and/or description of an order for various steps should not be understood to require a particular order of execution for those steps, unless required by a particular application, or explicitly stated or otherwise clear from the context.
The methods and/or processes described above, and steps associated therewith, may be realized in hardware, software or any combination of hardware and software suitable for a particular application. The hardware may include a general-purpose computer and/or dedicated computing device or specific computing device or particular aspect or component of a specific computing device. The processes may be realized in one or more microprocessors, microcontrollers, embedded microcontrollers, programmable digital signal processors or other programmable devices, along with internal and/or external memory. The processes may also, or instead, be embodied in an application specific integrated circuit, a programmable gate array, programmable array logic, or any other device or combination of devices that may be configured to process electronic signals. It will further be appreciated that one or more of the processes may be realized as a computer executable code capable of being executed on a machine-readable medium.
The computer executable code may be created using a structured programming language such as C, an object oriented programming language such as C++, or any other high-level or low-level programming language (including assembly languages, hardware description languages, and database programming languages and technologies) that may be stored, compiled or interpreted to run on one of the above devices, as well as heterogeneous combinations of processors, processor architectures, or combinations of different hardware and software, or any other machine capable of executing program instructions.
Thus, in one aspect, methods described above and combinations thereof may be embodied in computer executable code that, when executing on one or more computing devices, performs the steps thereof. In another aspect, the methods may be embodied in systems that perform the steps thereof, and may be distributed across devices in a number of ways, or all of the functionality may be integrated into a dedicated, standalone device or other hardware. In another aspect, the means for performing the steps associated with the processes described above may include any of the hardware and/or software described above. All such permutations and combinations are intended to fall within the scope of the present disclosure.
While the disclosure has been provided in connection with the many embodiments shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the spirit and scope of the present disclosure is not to be limited by the foregoing examples, but is to be understood in the broadest sense allowable by law.
The use of the terms “a” and “an” and “the” and similar referents in the context of describing the disclosure (especially in the context of the following claims) is to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. Recitations of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the disclosure and does not pose a limitation on the scope of the disclosure unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosure.
While the foregoing written description enables one skilled in the art to make and use what is considered presently to be the best mode thereof, those skilled in the art will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The disclosure should therefore not be limited by the above described embodiments and examples, but by all embodiments and examples within the scope and spirit of the disclosure.
Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specified function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112(f). In particular, any use of “step of” in the claims is not intended to invoke the provision of 35 U.S.C. § 112(f).
Persons skilled in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present disclosure, the scope of the invention is reflected by the breadth of the claims below rather than interpreted in light of the embodiments described above.
