Embodiments of the disclosure generally relate to structure bodies such as for use in nuclear reactor buildings, and in particular, to structure bodies formed from steel-panel composite wall panel structures.
Buildings such as plants used in nuclear facilities, military facilities, and the like may include structure bodies such as building housings for accommodating equipment such as safety-related equipment. Such a structure body can be built by assembling a plurality of modules that have already been manufactured according to the functions and the like of the equipment to be accommodated. Structures used for manufacturing these modules are required to have high structural strength to ensure the integrity of the structure body to be built. These structures may include steel-plate composite (SC) wall panel structures. An SC wall panel structure can generally include two steel plates between which concrete is disposed. For example, there is a technique for constructing a structure body such as a building housing for a nuclear plant using such an SC wall panel structure. In addition, according to the technique, some unit modules each formed by SC wall panel structures are manufactured at an off-site location away from a construction site or at an on-site location where the structure body is to be constructed. If manufactured off-site, the unit modules are transported to the on-site location via sea or land, and then these transported unit modules are assembled into the structure body at the on-site location.
The manufactured SC wall panel structure 10, however, may not be practically transported (e.g., by ship or rail) due to the weight of the concrete 5 filled between the steel plates 1 and 2. On the other hand, since filing the structure with concrete 5 adds structure, the SC wall panel structure 10 may not have sufficient strength to bear inertial and/or other forces that may be applied during transportation, if the SC wall panel structure 10 is transported without the concrete 5 being installed.
Many aspects of the present technology can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale. Instead, emphasis is placed on clearly illustrating the principles of the present technology.
Aspects of the present technology are directed generally toward structures for forming a module, such as a module for use in a nuclear reactor building. In several of the embodiments described below, a panel structure can include a first plate, a second plate spaced apart from and extending parallel to the first plate, and a support assembly positioned between the first plate and the second plate. The support assembly can include a column, a first beam extending from the column in a first direction parallel to the first plate and the second plate, and a second beam extending from the column in a second direction parallel to the first plate and the second plate. The second direction can be opposite to the first direction, and the first and second directions can be perpendicular to a longitudinal axis of the column. The panel structure can further include a plurality of joint plates extending between the first plate and the second plate and connecting the first plate to the second plate. The joint plates can be spaced apart from and extend parallel to one another, and can be coupled to the first beam and the second beam to support the first beam and the second beam. The panel structure can further include a fill material, such as concrete, between the first plate and the second plate and surrounding the support assembly and the joint plates.
In some embodiments, the panel structure can be assembled at a first location without the fill material. The panel structure can then be shipped to a second location remote from the first location, where the fill material can be filled between the first plate and the second plate. In some aspects of the present technology, the support assembly and the joint plates provide strength and rigidity to the panel structure during shipping that can reduce or even prevent damage to the panel structure when the fill material has not yet been disposed between the first plate and the second plate. Accordingly, the panel structure can be reliably shipped to the second location without the fill material—substantially reducing the weight of the panel structure and cost/difficulty of transportation—where it can be subsequently filled with the fill material at the second location to provide a permanent structure, such as a portion of a structure enclosing a nuclear reactor.

Certain details are set forth in the following description and in
The accompanying Figures depict embodiments of the present technology and are not intended to limit its scope unless expressly indicated. The sizes of various depicted elements are not necessarily drawn to scale, and these various elements may be enlarged to improve legibility. Component details may be abstracted in the Figures to exclude details such as position of components and certain precise connections between such components when such details are unnecessary for a complete understanding of how to make and use the present technology. Many of the details, dimensions, angles and other features shown in the Figures are merely illustrative of particular embodiments of the disclosure. Accordingly, other embodiments can have other details, dimensions, angles and features without departing from the present technology. In addition, those of ordinary skill in the art will appreciate that further embodiments of the present technology can be practiced without several of the details described below.
In some embodiments, the first steel plate 1 and the second steel plate 2 can each include an inner surface from which multiple studs 4 protrude generally in a normal (e.g., orthogonal, perpendicular) direction from the corresponding one of the first and second steel plates 1, 2. The studs 4 can be headed studs such that studs 4 can enhance the connectivity between the steel plates 1, 2 and concrete and/or another fill material (not shown) that can be later disposed (e.g., filled) between the first and second steel plates 1, 2. The first and second steel plates 1, 2 and the joint plates 20 can be formed from steel material, such as stainless steel, and/or other suitably rigid (e.g., metal) materials. Accordingly, while generally referred to herein as “steel plates,” the first and second steel plates 1, 2 can be formed of materials other than steel. In the illustrated embodiment, the SC wall panel structure 100 can further include a connection line 101, which can be formed when an upper SC wall panel structure 100A is connected to a lower SC wall panel structure 100B by a connection means such as welding. The connection line 101 is depicted as dash-dot-dash line in
The SC wall panel structure 100 can further include a column-beam assembly 30 (e.g., a support assembly) disposed between the first steel wall 1 and the second steel wall 2. The column-beam assembly 30 can include a column 35 vertically extending (e.g., along a longitudinal axis) between the first steel plate 1 and the second steel plate 2, and two beams 33 extending to oppose each other from the column 35 (e.g., in opposite directions from the column 35). The beams 33 can extend substantially perpendicular to a longitudinal axis of the column 35 (e.g., horizontally) between the first steel plate 1 and the second steel plate 2. In the column-beam assembly 30, the column 35 and the two beams 33 can form moment connections to convey a moment load acting on the beams 33 to the column 35, as described in, for example Chapter 10 of ANSI/AISC 358-16 ANSI/AISC 358s1-18, An American National Standard, Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications, including Supplement No. 1, May 12, 2016, (includes 2018 supplement).
In the illustrated embodiment, each of the joint plates 20 is disposed between the first steel plate 1 and the second steel plate 2 to connect the first steel plate 1 to the second steel plate 2. The upper joint plates 20A can be spaced apart from one another and extend in a row between the first steel plate 1 and the second steel plate 2. Likewise, the lower joint plates 20B can be spaced apart from one another and extend in a row between the first steel plate 1 and the second steel plate 2. The two beams 33 extend between the rows of the upper and lower joint plates 20A, 20B and are supported by the joint plates 20 such that the column-beam assembly 30 can be positioned between the first steel plate 1 and the second steel plate 2. More specifically, the beams 33 are configured to be sandwiched between adjacent pairs of the joint plates 20 that are vertically offset from and adjacent to one another—such as between the pair comprising the first joint plate 20A and the second joint plate 20B. Each of the joint plates 20 can have a lattice-like pattern formed by a plurality of horizontally-extending portions 201 that may extend in a direction normal to the first and second steel plates 1, 2, and a plurality of vertically-extending extending portions 202 that may extend in a direction parallel to the first and second steel plates 1, 2 between two adjacent ones of the horizontally-extending portions 201. In the illustrated embodiment, each of the joint plates 20 includes two vertically-extending portions 202 that vertically extend in parallel with each other. Edges of the horizontally-extending portions 201 can be connected to respective ones of the first and second steel plates 1, 2. The connection between the joint plates 20 and the first and second steel plates 1, 2 can be performed by welding and/or another suitable technique. Although two vertically-extending portions 202 are depicted in the illustrated embodiment, more or fewer than two vertically-extending portions 202 can be included in each of the joint plates 20. Further, although three horizontally-extending portions 201 are depicted in the illustrated embodiment, each of joint plates 20 can include more or fewer than three horizontally-extending portions 201.
The beam 33 can include an upper beam flange 34A and a lower beam flange 34B at respective edges of the beam 33 that vertically oppose each other. The beam 33 with the upper and lower beam flanges 34A and 34B may be commonly referred to as an I-section beam or H-section beam herein. Referring to
The double angles 44A that can be provided opposing each other via the joint plate 20A (and welded to the beam flange 34A and the joint plate 20A) can each have a substantially L-shaped cross section taken along a direction parallel with the planes of the first and second steel plates 1, 2. Similarly, the double angles 44B that can be provided opposing each other via the joint plate 20B (and welded to the beam flange 34B and the joint plate 20B) can each have a substantially L-shape cross section taken along a direction parallel with the planes of the first and second steel plates 1, 2. The cutouts 21A and 21B can have a shape, size, dimension, etc., corresponding to the shape, size, dimension, etc., of the upper and lower beam flanges 34A and 34B, respectively. Although an upper pair of double angles 44A and a lower pair of double angles 44B are shown in
The cutout 21B provided in the lower joint plate 20B can receive the lower beam flange 34B of the beam 33 when the beam 33 is vertically lowered onto the lower joint plate 20B during manufacturing of the SC wall panel structure 100. Thus, the cutout 21B can facilitate positioning the beam 33 when the SC wall panel structure 100 is manufactured. Further, when the upper joint plate 20A and the first and second steel plates 1, 2 are assembled into an assembly such as the upper SC wall panel structure 100A shown in
In the illustrated embodiment, the column 35 is a tube formed from steel (e.g., stainless steel) and/or another suitably rigid material (e.g., metal), and has a rectilinear (e.g., square, rectangular) cross-sectional shape. Referring to

The I-shaped, L-shaped, and T-shaped SC wall panel structures 500, 600, and 700 as described above can be formed into a module having a wide variety of configurations, for example, by vertically stacking an upper column 535 onto a lower column 535 to be aligned with each other according to the embodiments described referring to
Although the SC wall panel structures 100 and 500 are depicted to include the columns 35 and 535 extending vertically in the illustrated embodiments, an SC floor panel structure or an SC ceiling panel structure can be formed to include the columns 35 and 535 extending horizontally in a certain application. Thus, such SC wall panel structures, SC floor panel structures, and SC ceiling structures can be used to form a module. In particular, at least one of a side surface, a top surface, and a bottom surface of the module can be defined by such SC wall panel structures, SC floor panel structures, and SC ceiling structures.
Further, a plurality of modules formed using such SC wall panel structures, SC floor panel structures, and SC ceiling structures can be connected horizontally or vertically into a structure body.
In some aspects of the present technology, such SC wall panel structures, SC floor panel structures, and SC ceiling structures (hereinafter collectively referred to as structures) manufactured at an off-site location away from a construction site or at an on-site location can have a strength that can bear an inertia load (and/or other loads) experienced during the transportation from the off-site location to the on-site location. Specifically, the SC panel structures of the present technology can have a configuration in which a column-beam assembly is supported by joint plates sandwiched between the opposing steel plates to connect these steel plates to each other in the structures. When the structures form a portion of a module or a structure body after being transported to the on-site location, a space between the steel plates can be filled (or at least partially filled) with concrete. In addition, the associated columns, formed as a steel tube, can also be filled (or at least partially filled) with concrete, such that the structures can exhibit a structural strength that can prevent the structures from collapsing when used in the module or the structure body. Such a process of disposing concrete in the structures can be performed prior to the structures forming the module or the structure body. Alternatively, the concrete can be disposed in the module or the structure body after multiple modules and/or structure bodies have been assembled into a structure. Accordingly, the SC structures of the present technology can be strong enough to be shipped to an on-site location for assembly into a modular structure, while also being light enough to be practically shipped because they are not filled with concrete until assembly at the on-site location.
The SC panel structures of the present technology can be used to fully or partially enclose a nuclear reactor system. For example, the SC panel structures can form all or portion of a module that at least partially surrounds a nuclear reactor. The module can comprise, for example, a reactor building wall or enclosure. More specifically,
The power module 102 includes a containment vessel 110 (e.g., a radiation shield vessel, or a radiation shield container) that houses/encloses a reactor vessel 120 (e.g., a reactor pressure vessel, or a reactor pressure container), which in turn houses the reactor core 104. The containment vessel 110 can be housed in a power module bay 156. The power module bay 156 can contain a cooling pool 103 filled with water and/or another suitable cooling liquid. The bulk of the power module 102 can be positioned below a surface 105 of the cooling pool 103. Accordingly, the cooling pool 103 can operate as a thermal sink, for example, in the event of a system malfunction. In some embodiments, the SC structures of the present technology can be used to form at least part of the power module bay 156 and/or a further structure (e.g., a reactor building, a reactor structure) that houses the power module bay 156.
A volume between the reactor vessel 120 and the containment vessel 110 can be partially or completely evacuated to reduce heat transfer from the reactor vessel 120 to the surrounding environment (e.g., to the cooling pool 103). However, in other embodiments the volume between the reactor vessel 120 and the containment vessel 110 can be at least partially filled with a gas and/or a liquid that increases heat transfer between the reactor vessel 120 and the containment vessel 110.
Within the reactor vessel 120, a primary coolant 107 conveys heat from the reactor core 104 to the steam generator 130. For example, as illustrated by arrows located within the reactor vessel 120, the primary coolant 107 is heated at the reactor core 104 toward the bottom of the reactor vessel 120. The heated primary coolant 107 (e.g., water with or without additives) rises from the reactor core 104 through a core shroud 106 and to a riser tube 108. The hot, buoyant primary coolant 107 continues to rise through the riser tube 108, then exits the riser tube 108 and passes downwardly through the steam generator 130. The steam generator 130 includes a multitude of conduits 132 that are arranged circumferentially around the riser tube 108, for example, in a helical pattern, as is shown schematically in
The steam generator 130 can include a feedwater header 131 at which the incoming secondary coolant enters the steam generator conduits 132. The secondary coolant rises through the conduits 132, converts to vapor (e.g., steam), and is collected at a steam header 133. The steam exits the steam header 133 and is directed to the power conversion system 140.
The power conversion system 140 can include one or more steam valves 142 that regulate the passage of high pressure, high temperature steam from the steam generator 130 to a steam turbine 143. The steam turbine 143 converts the thermal energy of the steam to electricity via a generator 144. The low-pressure steam exiting the turbine 143 is condensed at a condenser 145, and then directed (e.g., via a pump 146) to one or more feedwater valves 141. The feedwater valves 141 control the rate at which the feedwater re-enters the steam generator 130 via the feedwater header 131.
The power module 102 includes multiple control systems and associated sensors. For example, the power module 102 can include a hollow cylindrical reflector 109 that directs neutrons back into the reactor core 104 to further the nuclear reaction taking place therein. Control rods 113 are used to modulate the nuclear reaction, and are driven via fuel rod drivers 115. The pressure within the reactor vessel 120 can be controlled via a pressurizer plate 117 (which can also serve to direct the primary coolant 107 downwardly through the steam generator 130) by controlling the pressure in a pressurizing volume 119 positioned above the pressurizer plate 117.
The sensor system 150 can include one or more sensors 151 positioned at a variety of locations within the power module 102 and/or elsewhere, for example, to identify operating parameter values and/or changes in parameter values. The data collected by the sensor system 150 can then be used to control the operation of the system 100, and/or to generate design changes for the system 100. For sensors positioned within the containment vessel 110, a sensor link 152 directs data from the sensors to a flange 153 (at which the sensor link 152 exits the containment vessel 110) and directs data to a sensor junction box 154. From there, the sensor data can be routed to one or more controllers and/or other data systems via a data bus 155.
In the illustrated embodiment, the system 200 includes a reactor vessel 220 and a containment vessel 210 surrounding/enclosing the reactor vessel 220. In some embodiments, the reactor vessel 220 and the containment vessel 210 can be roughly cylinder-shaped or capsule-shaped. In some embodiments the reactor vessel 220 and the containment vessel can be positioned in a reactor housing, a reactor bay, a reactor building, and/or the like formed from one or more of the SC structures of the present technology.
The system 200 further includes a plurality of heat pipe layers 211 within the reactor vessel 220. In the illustrated embodiment, the heat pipe layers 211 are spaced apart from and stacked over one another. In some embodiments, the heat pipe layers 211 can be mounted/secured to a common frame 212, a portion of the reactor vessel 220 (e.g., a wall thereof), and/or other suitable structures within the reactor vessel 220. In other embodiments, the heat pipe layers 211 can be directly stacked on top of one another such that each of the heat pipe layers 211 supports and/or is supported by one or more of the other ones of the heat pipe layers 211.
In the illustrated embodiment, the system 200 further includes a shield or reflector region 214 at least partially surrounding a core region 216. The heat pipes layers 211 can be circular, rectilinear, polygonal, and/or can have other shapes, such that the core region 216 has a corresponding three-dimensional shape (e.g., cylindrical, spherical). In some embodiments, the core region 216 is separated from the reflector region 214 by a core barrier 215, such as a metal wall. The core region 216 can include one or more fuel sources, such as fissile material, for heating the heat pipes layers 211. The reflector region 214 can include one or more materials configured to contain/reflect products generated by burning the fuel in the core region 216 during operation of the system 200. For example, the reflector region 214 can include a liquid or solid material configured to reflect neutrons and/or other fission products radially inward toward the core region 216. In some embodiments, the reflector region 214 can entirely surround the core region 216. In other embodiments, the reflector region 214 may partially surround the core region 216. In some embodiments, the core region 216 can include a control material 217, such as a moderator and/or coolant. The control material 217 can at least partially surround the heat pipe layers 211 in the core region 216 and can transfer heat therebetween.
In the illustrated embodiment, the system 200 further includes at least one heat exchanger 230 (e.g., a steam generator) positioned around the heat pipe layers 211. The heat pipe layers 211 can extend from the core region 216 and at least partially into the reflector region 214, and are thermally coupled to the heat exchanger 230. In some embodiments, the heat exchanger 230 can be positioned outside of or partially within the reflector region 214. The heat pipe layers 211 provide a heat transfer path from the core region 216 to the heat exchanger 230. For example, the heat pipe layers 211 can each include an array of heat pipes that provide a heat transfer path from the core region 216 to the heat exchanger 230. When the system 200 operates, the fuel in the core region 216 can heat and vaporize a fluid within the heat pipes in the heat pipe layers 211, and the fluid can carry the heat to the heat exchanger 230.
In some embodiments, the heat exchanger 230 can be similar to the steam generator 130 of
