1. System
As shown in the FIGURES, a compact nuclear reactor system 100 can include a set of nuclear reactor cores arranged around a longitudinal axis. As shown in the FIGURES, each of the set of nuclear reactor cores can further include: a moderating body; a heat pipe disposed within the moderating body and arranged substantially parallel to the longitudinal axis; nuclear fuel arranged within the moderating body and configured to heat a working fluid passable through the heat pipe; and a neutron moderator arranged within the moderating body and configured to slow a rate of fission within the moderating body. The compact nuclear reactor system 100 can also include a control system including: in a subset of the set of nuclear reactor cores, a sleeve defining a sleeve axis arranged about the moderating body such that the sleeve axis is substantially parallel to the longitudinal axis. As shown in the FIGURES, the sleeve can include: a first portion including a neutron poison material; and a second portion including a neutron transparent material. The compact nuclear reactor system 100 can also include a drive system connected to the sleeve and configured to rotate the sleeve about the sleeve axis to control neutron flux between the set of nuclear reactor cores.
In one variation of the example implementation, the system 100 can further include a heat exchange system in communication with the set of nuclear reactor cores and configured to operate in a first state within a first temperature range; and a heat exchange controller connected to the heat exchange system and configured to direct the control system to rotate the sleeve to adjust a neutron flux in response to the heat exchange system operating in a second state different from the first state.
In another variation of the example implementation, the system 100 can include a set of peripheral moderating bodies, each of the set of peripheral moderating bodies: defining a substantially elongated body along a peripheral moderator axis substantially parallel with the longitudinal axis; and arranged at a radial distance between the peripheral moderator axis and the longitudinal axis. Moreover, the system 100 can further include a central moderating body defining a substantially elongated body along a central moderator axis substantially coaxial with the longitudinal axis.
As shown in the FIGURES, in another variation of the example implementation, the system 100 can include a first nuclear reactor core arranged around a longitudinal axis and including: a first moderating body; a first heat pipe disposed within the first moderating body and arranged substantially parallel to the longitudinal axis; first nuclear fuel arranged within the first moderating body and configured to heat a working fluid passable through the first heat pipe; a first neutron moderator arranged within the first moderating body and configured to slow a rate of fission within the first moderating body. As shown in the FIGURES, the system 100 can also include a second nuclear reactor core arranged around a longitudinal axis and including: a second moderating body; a second heat pipe disposed within the second moderating body and arranged substantially parallel to the longitudinal axis; a second nuclear fuel arranged within the second moderating body and configured to heat a working fluid passable through the second heat pipe; and a second neutron moderator arranged within the second moderating body and configured to slow a rate of fission within the second moderating body.
As shown in the FIGURES, the system 100 can also include a control system including: a sleeve defining a sleeve axis arranged about the first moderating body such that the sleeve axis is substantially parallel to the longitudinal axis. The sleeve can include: a first portion including a neutron poison material; and a second portion including a neutron transparent material. As shown in the FIGURES, the system 100 can also include a drive system connected to the sleeve and configured to rotate the sleeve about the sleeve axis to adaptively and/or responsively control neutron flux between the first nuclear reactor core and the second nuclear reactor core.
2. Applications
Generally, the system 100 described herein is suitable for deployment and use in any application for which controlled nuclear power is either required or desired. More specifically, the system 100 can be deployed in terrestrial and space environments in which the space constraints, packaging constraints, weight constraints, or a combination thereof prohibit or otherwise limit the use of conventionally-designed compact nuclear reactor systems. For example, the system 100 can be deployed temporarily or semi-permanently at terrestrial sites including: austere environments such as military forward operating bases, remote mineral extraction sites, remote settlements, villages, or depots. Additionally, the system 100 can be deployed in urban environments to provide residential power and/or to supplement existing power infrastructure including renewable energy power production that may exhibit uneven or cyclical energy production (e.g., irregular solar radiation or wind speed). The system 100 can be implemented in a compact and portable configuration that permits easy integration into existing power infrastructure to provide reliable and controllable nuclear power on demand.
Moreover, as described in detail below, the system 100 controls neutron flux, fission reaction, and heat production through the use of self-contained, rotatable sleeves that selectively permit the passage of neutrons between sets of nuclear reactor cores. In doing so, the system 100 eliminates the need for cumbersome, costly, and space-consuming apparatuses such as control rods that must extend in and out of the nuclear reactor cores in order to control the production of heat and ensure that the system 100 remains stable. As a result, the system 100 can be deployed in a multitude of additional environments and/or applications for which nuclear power production is desirable but previously unattainable due to size, weight, and packaging constraints.
In one example implementation, the system 100 can be deployed for long-range space travel for manned or unmanned space vehicles and/or extraterrestrial settlements (e.g., lunar or Martian settlements). Because of the compact and lightweight configurations attainable by the system 100, spacecraft designers may have an increased range of options to design and build a coming generation of long-range and/or long-duration space vehicles that can provide consistent and reliable power throughout the duration of their journey. Moreover, because of the lightweight and compact design of the system 100, it can also be deployed on land-based vehicles (terrestrial, lunar, Martian) to provide consistent electrical and/or heat power and thereby enable movement about the surface.
In one variation of the system 100 described in detail below, the system 100 can include or be coupled with a Stirling engine that is configured to perform work in response to a temperature gradient between two components of the system 100. For example, the system 100 can include a Stirling engine that is: thermally coupled to the nuclear reactor cores via a set of heat pipes; and thermally coupled to a radiator configured and shaped to dissipate heat from the working fluid into the environment. In operation, the system 100 can implement controls described herein to achieve and/or maintain a temperature of the working fluid as it passes through the nuclear reactor cores by adjusting a fission rate within the nuclear reactor cores. As the system 100 is configured to continuously and responsively adjust its power production based upon neutron flux and/or temperature measurements, a Stirling engine included with or coupled to the system 100 can operate at a maximum efficiency for a long duration.
These and other features, applications, and advantages of the system 100 are described below in detail with reference to the FIGURES.
3. Nuclear Reactor Cores
As shown in
As shown in
Generally, the moderating body 112, 122 can be composed of or manufactured in a material such as graphite that slows emitted neutrons and increases the probability that these emitted neutrons will be absorbed by adjacent nuclear fuel atoms, thereby maintaining the criticality of the nuclear fuel and the continuous production of heat through fission reactions. In one variation of the example implementation, the moderating body 112, 122 can include a monolithic graphite prismatic block including or defining a set of channels, pockets, holes, and/or passages machined or manufactured therein. Alternatively, the moderating body 112, 122 can include a set of graphite prismatic blocks, each including or defining a set of channels, pockets, holes, and/or passages machined or manufactured therein, arranged in a polylithic unitary structure.
As shown in
As shown in
As shown in
For example, the geometry of the channels containing nuclear fuel 170 and/or nuclear poison 172 may depend upon the geometry of the entire system 100, the number of nuclear reactor cores 110, 120 included in the system 100, and the geometric arrangement of the set of nuclear reactor cores 110, 120 within the system 100.
4. Control Systems
As shown in
4.1 Nuclear Reactor Core Sleeves
In one variation of the example implementation, the system 100 can include: in a subset of the set of nuclear reactor cores 110, 120, a sleeve 111, 121 defining a sleeve axis 118, 128 arranged about the moderating body 112, 122 such that the sleeve axis 118, 128 is substantially parallel to the longitudinal axis 130. Generally, each sleeve 111, 121 can include a first portion 114, 124 including or manufactured from a neutron poison material; and a second portion 116, 126 including or manufactured from a neutron transparent material. As described in detail below, the sleeve 111, 121 is composed of or manufactured from distinct materials (e.g., first and second portions 114, 116, 124, 126) and configured to be rotatable about each respective moderating body 112, 122 such that a neutron flux between the set of nuclear reactor cores 110, 120 can be dynamically and/or responsively adjusted.
As shown in
In another variation of the example implementation shown in
As shown in
In another variation of the example implementation of the system 100, the sleeve 111 can further define a third portion disposed adjacent to and/or within one or both of the first portion 114 or the second portion 116. For example, the third portion of the sleeve 111 can include or be composed of a different neutron poison material, a different neutron moderating material, or a composite, doped, or blended material that functions to transition between neutron absorption and neutron transparency. For example, the third portion of the sleeve 111 can be arranged at transition points between the first portion 114 and the second portion 116 such that the neutron flux emanating from the nuclear reactor core no is gradually increased along an angular transition from the first portion 114 to the second portion 116 and gradually decreased along an angular transition from the second portion 116 to the first portion 114.
In another variation of the example implementation, the first portion 114 can include or be composed of a layer of neutron poison material that is of substantially uniform thickness as measured along a radial line emanating orthogonal to the sleeve axis 118. For example, the first portion 114 can include a boron carbide plate, layer, or component that is of uniform thickness throughout its entire angular span.
Alternatively, the first portion 114 can include or be composed of a layer of neutron poison material that is of substantially non-uniform thickness as measured along a radial line emanating orthogonal to the sleeve axis 118. For example, the thickness of the first portion 114 can be graded across its angular span such that it is thicker along lines of greater potential neutron flux and thinner along lines of lesser potential neutron flux, as determined according to the number of nuclear reactor cores and their geometric arrangement within the system 100.
In other variations and alternative configurations of the example implementation, the sleeve 111, 121 can define other geometries or cross-sections. For example, in some alternative configurations, the sleeve 111, 121 can define a triangular cross-section and include one or more surfaces or sides including or defining materials with distinct neutron absorption properties. For example, in a triangular configuration, one side of the triangular sleeve 111, 121 can include or be composed of a neutron poison material and the other two sides of the triangular sleeve can include or be composed of a neutron transparent or moderating material. In this example alternative configuration, if the triangular cross-section is an equilateral triangle, then the first side of the triangle (e.g., a boron carbide surface) would absorb or substantially absorb neutrons spanning a one hundred twenty degree angle (measured in a plane normal to the sleeve axis 118) while the second and third sides of the triangle (e.g., graphite or silicon carbide) would moderate or transmit neutrons spanning a two hundred forty degree angle (measured in a plane normal to the sleeve axis).
In still other variations or alternative configurations of the example implementation, the sleeve 111, 121 can define any other polygonal cross-section (e.g., rectangular, square, rhomboid, pentagonal, hexagonal, etcetera) and include or define sides surfaces or sides including or defining materials with distinct neutron absorption properties. Alternatively, the sleeve 111, 121 can define a non-polygonal cross-section or an asymmetrical cross-section (e.g., tear-drop, oblong, elliptical, etcetera). Furthermore, the system 100 can include a set of nuclear reactor cores, some (or all) of which are enshrouded in sleeves 111, 121 having distinct cross-sections as described above depending upon the arrangement, geometry, and packaging of the system 100 and the nuclear reactor cores.
4.2. Drive System
As shown in
In one variation of the example implementation, the drive system 150 can include a mechanical or electro-mechanical rotor/stator pair, motor, gear-box, or any combination thereof that is mechanically and/or electrically coupled to the sleeve and rotate the sleeve 111, 121 about the sleeve axis 118 and thereby adjust the position of the first portion 114 of the sleeve relative to another (or a set of) nuclear reactor core 110, 120 in the system 100. Generally, the sleeve 111, 121 is rotatable about a static moderator block 112, 122 (within the frame of reference of the system 100). However, in alternative variations of the example implementation, the sleeve 111, 121 and the moderator block 112, 122 can rotate in unison as a singular rotatable nuclear reactor core 110, 120 within the system 100. In still other variations of the example implementation, a subset of sleeves 111, 121 and the moderator blocks 112, 122 can be configured as a unified and rotatable nuclear reactor core 110, 120 within the set of nuclear reactor cores within the system 100.
In one variation of the example implementation, the drive system 150 can be arranged within a singular pressure vessel containing the system 100. Alternatively, the drive system 150 can be arranged external to the pressure vessel containing the nuclear reactor cores 110, 120 and mated or coupled to the sleeves 111, 121 through a barrier, shield, or boundary separating the mechanism of the drive system 150 from the nuclear reactor cores 110, 120.
For example, as shown in
As shown in
In operation, if the sensor 154 generates a signal indicating that the neutron flux within the system 100 is increasing (e.g., trending toward or above a threshold) indicative of excess fission within the nuclear reactor cores 110, 120, then the drive system 150 can rotate the sleeve 111 around the sleeve axis 118 such that the first portion 114 of the sleeve is proximate the longitudinal axis 130 and the second portion 116 of the sleeve is distal the longitudinal axis 130. As shown in the FIGURES, in configurations in which the nuclear reactor cores 110, 120 are arranged opposite the longitudinal axis 130, rotation of the sleeve 111 such that the first portion 114 is proximate the longitudinal axis 130 interposes the first portion 114 between the moderator blocks 112, 122 and thereby reduces neutron flux between the moderator blocks 112, 122.
In one variation of the example implementation, the drive system 150 can be configured to rotate a single sleeve 111 about a moderator block 112 such that the first portion 114 is proximate the longitudinal axis 130 and the second portion 116 is distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can therefore slow, moderate, or impede neutron transmission between the moderator blocks 112, 122.
In another variation of the example implementation, the drive system 150 can be configured to rotate both sleeves 111, 121 about the moderator blocks 112, 122 such that the first portions 114, 124 are proximate the longitudinal axis 130 and the second portions 116, 126 are distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can further slow, moderate, or impede neutron transmission between the moderator blocks 112, 122.
In another variation of the example implementation in which the system 100 includes more than two nuclear reactor cores 110, 120, the drive system 150 can be configured to rotate multiple (e.g., more than two) sleeves 111, 121 about the moderator blocks 112, 122 such that the first portions 114, 124 are proximate the longitudinal axis 130 and the second portions 116, 126 are distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can further slow, moderate, or impede neutron transmission between the moderator blocks 112, 122.
In yet another variation of the example implementation, the drive system 150 can be configured to responsively and/or proportionally rotate the sleeve 111 at a proportional rate about a moderator block 112 such that the first portion 114 is proximate the longitudinal axis 130 and the second portion 116 is distal the longitudinal axis 130. If the controller 152 determines that a rate of increase in neutron flux is expected or anticipated to cause a neutron flux count to exceed a threshold, then the controller 152 can proportionally cause and/or direct the drive system 150 to rotate the sleeve 111 about the moderator block 112 as described above to slow, moderate, or impede neutron transmission between the moderator blocks 112, 122. For example, if the rate of increase in neutron flux is high (e.g., neutron flux is increasing rapidly), then the controller 152 can direct the drive system 150 to rapidly rotate the sleeve 111 about the moderator block 112 and rapidly counteract the increase in neutron flux. Conversely, if the rate of increase in neutron flux is low (e.g., neutron flux is increasing slowly), then the controller 152 can direct the drive system 150 to slowly rotate the sleeve 111 about the moderator block 112 to slowly moderate the increase in neutron flux.
In alternative variations of the example implementation, the drive system 150 can execute similar techniques and methods to counteract and/or moderate an increase in neutron flux in systems 100 having two or more sleeves 111, 121 rotatable about two or more nuclear reactor cores 110, 120.
In yet another variation of the example implementation, the drive system 150 can be configured to responsively and/or proportionally rotate the sleeve 111 at a proportional angular/impeding distance about a moderator block 112 such that the first portion 114 is proximate the longitudinal axis 130 and the second portion 116 is distal the longitudinal axis 130. If the controller 152 determines that a rate of increase in neutron flux is expected or anticipated to cause a neutron flux count to exceed a threshold, the controller 152 can proportionally cause and/or direct the drive system 150 to rotate the sleeve 111 about the moderator block 112 as described above to slow, moderate, or impede neutron transmission between the moderator blocks 112, 122. For example, if the rate of increase in neutron flux is high (e.g., neutron flux is increasing rapidly), then the controller 152 can direct the drive system 150 to fully rotate the sleeve 111 about the moderator block 112 such that the entirety of the first portion 114 is centered between the sleeve axis 118 and the longitudinal axis 130 in order to maximally counter the calculated increase in neutron flux. Conversely, if the rate of increase in neutron flux is low (e.g., neutron flux is increasing slowly), then the controller 152 can direct the drive system 150 to partially rotate the sleeve 111 about the moderator block 112 such that only an angular section of the first portion 114 is interposed between the sleeve axis 118 and the longitudinal axis 130 in order to slowly moderate the increase in neutron flux.
In alternative variations of the example implementation, the drive system 150 can execute similar techniques and methods to counteract and/or moderate an increase in neutron flux in systems 100 having two or more sleeves 111, 121 rotatable about two or more nuclear reactor cores 110, 120.
In operation, if the sensor 154 generates a signal indicating that the neutron flux within the system 100 is decreasing (e.g., trending toward or below a threshold) indicative of insufficient fission within the nuclear reactor cores 110, 120, then the drive system 150 can rotate the sleeve 111 around the sleeve axis 118 such that the first portion 114 of the sleeve 111 is distal the longitudinal axis 130 and the second portion 116 of the sleeve 111 is proximate the longitudinal axis 130. As shown in the FIGURES, in configurations in which the nuclear reactor cores 110, 120 are arranged opposite the longitudinal axis 130, rotation of the sleeve 111 such that the first portion 114 is distal the longitudinal axis 130 interposes the second portion 116 between the moderator blocks 112, 122 and thereby increases neutron flux between the moderator blocks 112, 122.
In one variation of the example implementation, the drive system 150 can be configured to rotate a single sleeve 111 about a moderator block 112 such that the second portion 116 is proximate the longitudinal axis 130 and the first portion 114 is distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can therefore increase or sustain neutron transmission between the moderator blocks 112, 122.
In another variation of the example implementation, the drive system 150 can be configured to rotate both sleeves 111, 121 about the moderator blocks 112, 122 such that the second portions 116, 126 are proximate the longitudinal axis 130 and the first portions 114, 124 are distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can further increase or sustain neutron transmission between the moderator blocks 112, 122.
In another variation of the example implementation in which the system includes more than two nuclear reactor cores 110, 120, the drive system 150 can be configured to rotate multiple (e.g., more than two) sleeves 111, 121 about the moderator blocks 112, 122 such that the second portions 116, 126 are proximate the longitudinal axis 130 and the first portions 114, 124 are distal the longitudinal axis 130. In this variation of the example implementation, the drive system 150 can further increase or sustain neutron transmission between the moderator blocks 112, 122.
In yet another variation of the example implementation, the drive system 150 can be configured to responsively and/or proportionally rotate the sleeve at a proportional rate about a moderator block 112 such that the second portion 116 is proximate the longitudinal axis 130 and the first portion 114 is distal the longitudinal axis 130. If the controller 152 determines that a rate of decrease in neutron flux is expected or anticipated to cause a neutron flux count to fall below a threshold, the controller 152 can proportionally cause and/or direct the drive system 150 to rotate the sleeve 111 about the moderator block 112, as described above, to increase or sustain neutron transmission between the moderator blocks 112, 122. For example, if the rate of decrease in neutron flux is high (e.g., neutron flux is decreasing rapidly), then the controller 152 can direct the drive system 150 to rapidly rotate the sleeve 111 about the moderator block 112 and rapidly counteract the decrease in neutron flux. Conversely, if the rate of decrease in neutron flux is low (e.g., neutron flux is decreasing slowly), then the controller 152 can direct the drive system 150 to slowly rotate the sleeve 111 about the moderator block 112 to slowly counteract the decrease in neutron flux.
In alternative variations of the example implementation, the drive system 150 can execute similar techniques and methods to counteract and/or moderate a decrease in neutron flux in systems 100 having two or more sleeves 111, 121 rotatable about two or more nuclear reactor cores 110, 120.
In yet another variation of the example implementation, the drive system 150 can be configured to responsively and/or proportionally rotate the sleeve 111 at a proportional angular/opening distance about a moderator block 112 such that the second portion 116 is proximate the longitudinal axis 130 and the first portion 114 is distal the longitudinal axis 130. If the controller 152 determines that a rate of decrease in neutron flux is expected or anticipated to cause a neutron flux count to fall below a threshold, the controller 152 can proportionally cause and/or direct the drive system 150 to rotate the sleeve 111 about the moderator block 112 as described above to increase or sustain neutron transmission between the moderator blocks 112, 122. For example, if the rate of decrease in neutron flux is high (e.g., neutron flux is decreasing rapidly), then the controller 152 can direct the drive system 150 to fully rotate the sleeve 111 about the moderator block 112 such that the entirety of the second portion 116 is centered between the sleeve axis 118 and the longitudinal axis 130 in order to maximally increase the potential neutron flux. Conversely, if the rate of decrease in neutron flux is low (e.g., neutron flux is decreasing slowly), then the controller 152 can direct the drive system 150 to partially rotate the sleeve 111 about the moderator block 112 such that only an angular section of the second portion 116 is interposed between the sleeve axis 118 and the longitudinal axis 130 in order to slowly moderate or counteract the decrease in neutron flux.
In alternative variations of the example implementation, the drive system 150 can execute similar techniques and methods to counteract and/or moderate a decrease in neutron flux in systems 100 having two or more sleeves 111, 121 rotatable about two or more nuclear reactor cores 110, 120.
In operation, the controller 152 and sensor 154 can cooperatively update and manage neutron flux within the system 100 by continuously and adaptively adjusting a position of the first and second portions 114, 116 of the sleeve 111 about the sleeve axis 118.
4.3 Heat Exchange System
As shown in
In one variation of the example implementation, the heat exchange system 200 can include a heat engine that is coupled to the nuclear reactor cores 110, 120 through the heat pipes 160, 162. For example, the heat exchange system 200 can derive power (thermal or electrical) from a temperature difference in a working fluid, such as a fluid passable through the heat pipes 160, 162. In one alternative variation of the example implementation, the heat exchange system 200 can include a Stirling engine that receives and recycles a working fluid through the nuclear reactor cores 110, 120 and a radiator or heat sink. In operation, the system 100 can heat a working fluid at the nuclear reactor cores 110, 120 and cool the same working fluid at a heat sink, thereby cycling the working fluid through variations in temperature to drive the Stirling engine.
As shown in
For example, a Stirling engine efficiency can depend, in part, upon the breadth of the temperature range between its high and low temperature points or components. Accordingly, the heat sensor 220 can measure a temperature range as well as a rate of change in the temperature range and direct these signals to the heat exchange controller 210. In response to the temperature range and rate of change in temperature range signals, the heat exchange controller 210 can: determine an increase, decrease, or stability in efficiency of the system 100; generate a signal indicative of the increase, decrease, or stability in efficiency of the system 100; and transmit the signal indicative of the increase, decrease, or stability in efficiency of the system 100 to the control system 152.
In another variation of the example implementation, the control system 152 can receive the signal indicative of the increase, decrease, or stability in efficiency of the system 100 and incorporate the same into the neutron flux controls described in detail above. For example, if the control system 152 receives a signal indicative of a decrease in efficiency of the system 100, the control system 152 can direct the drive system 150 to incrementally increase the neutron flux (and therefore fission reactions) at the nuclear reactor cores 110, 120 to increase the temperature of the working fluid, increase the temperature range of the system 100, and increase the efficiency of the heat exchange system 200.
5. Example Geometries
Generally, the system 100 can be configured in variations and alternative variations to those described herein. As noted above, in one configuration, the system 100 can include a pair of nuclear reactor cores 110, 120, each surrounded by a sleeve 111, 121 as shown in
