[0002] Existing commercial nuclear power units range in power from hundreds of thousands to millions of kilowatts. These units are large in size and occupy a significant area, requiring on-site construction at the designated site. The construction of the nuclear island and conventional island, both of which are key components, takes a long time, requiring extensive on-site civil engineering and installation personnel. Once completed, these units are immovable. Therefore, these units are more suitable for urban areas with favorable site conditions and high electricity consumption. They are not suitable for areas with limited infrastructure, such as isolated islands, mining areas, and remote areas with limited access to reliable external power sources. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art and provide a mobile nuclear energy device that requires no civil construction, can be quickly deployed, and has high mobility and high site adaptability. The present invention also provides a nuclear energy system.

[0004] The present invention provides a movable nuclear energy equipment, which is divided into multiple modules based on function, which can be transported independently and can be docked with each other to form a whole, including a primary loop system module and a working module. The primary loop system module is integrally encapsulated by a shielding body, and the primary loop system module is internally integrated with: a stack body for generating heat; a primary loop pipeline connected between the stack body and an intermediate heat exchanger; a first fan, arranged on the primary loop pipeline, for driving the primary loop medium in the primary loop pipeline to absorb the heat of the stack body and transport it to the intermediate heat exchanger; an intermediate heat exchanger, for exchanging heat between the primary loop medium and the working medium of the working module; the working module and the primary loop system module are detachably docked, and are used to supply energy through the working medium after heat exchange in the intermediate heat exchanger.

[0005] Furthermore, the internal space of the shielding body is a narrow and long rectangular chamber, and the stack body, the first-loop pipeline and the intermediate heat exchanger are arranged in sequence from the first end to the second end along the length direction of the rectangular chamber, so that the stack body and the intermediate heat exchanger are distributed at both ends of the rectangular chamber, and a control interface of the stack body is opened on the first end adjacent to the stack body to control the reactivity of the stack body through external equipment, and a docking interface of the intermediate heat exchanger is opened on the second end adjacent to the intermediate heat exchanger to dock the working module; the first fan is arranged in the side space of the first-loop pipeline, and is located between the stack body and the intermediate heat exchanger.

[0006] Furthermore, the longitudinal direction of the rectangular chamber is arranged horizontally, the stack body includes a stack container and a control rod drive structure, the stack container is arranged horizontally in the rectangular chamber in a horizontal form, and the control rod drive structure is arranged between the control interface and the stack container, and can be moved horizontally under the drive of an external device to control the reactivity of the stack container.

[0007] Furthermore, the primary-loop pipeline includes an inner tube and an outer tube, the outer diameter of the inner tube is smaller than the inner diameter of the outer tube, and the inner tube is sleeved inside the outer tube, the inner tube connects the stack body and the intermediate heat exchanger, and the outer tube connects the first fan and the stack body. The first fan drives the primary-loop medium along the outer tube into the stack body to absorb heat and then transported along the inner tube to the intermediate heat exchanger.

[0008] Furthermore, the primary-loop system module and the working module are connected through a secondary-loop pipeline to realize the circulation of working medium. A portion of the secondary-loop pipeline is located in the primary-loop system module, and one end is connected to the intermediate heat exchanger, and the other end is connected to the end face of the primary-loop system module to form a docking interface; another portion of the secondary-loop pipeline is located in the working module, and one end is connected to the working component of the working module, and the other end is connected to the end face of the working module to form a docking interface; the docking interface of the working module is docked with the docking interface of the primary-loop system module, so that the secondary-loop pipeline is docked into a whole.

[0009] Furthermore, the secondary circuit pipeline includes a cold section and a hot section arranged in parallel, which are respectively used to realize the circulation of working medium before and after heat exchange. The docking interface of the working module is docked with the docking interface of the primary circuit system module, so that the cold section of the secondary circuit pipeline is docked with the cold section, and the hot section is docked with the hot section.

[0010] Furthermore, the working modules are divided into two categories, namely, a thermoelectric conversion system module and a heat transfer module. The thermoelectric conversion system module is used to use the working medium after heat exchange to perform work and supply power, and the heat transfer module is used to use the working medium after heat exchange to provide heat. Either the thermoelectric conversion system module or the heat transfer module is connected to a single-loop system module.

[0011] Furthermore, the thermoelectric conversion system module includes a second fan, a turbine and a generator.

The steam generator is connected to the hot end through the three-circuit pipeline, and is used to supply the hot end after the three-circuit medium in the three-circuit pipeline exchanges heat with the working medium after heat exchange.

[0013] Furthermore, the movable nuclear energy equipment also includes an electrical and instrumentation auxiliary system module, which is internally integrated with: an electrical cabinet connected to each module for supplying power to the components inside the module; an instrumentation and control cabinet connected to each module for controlling the operation of the components inside the module; a primary circuit medium regulation system connected to the primary circuit pipeline for regulating the primary circuit medium state; and a first fan regulation system connected to the first fan for providing shaft sealing and cooling for the first fan.

Specifically, it includes a primary circuit system module equipped with a stack body and an intermediate heat exchanger, and a working module for utilizing heat for energy supply.

[0017] This equipment integrates various components that were originally complex and cumbersome and required on-site installation in sequence into modularized settings based on their functions. These components can then be connected and assembled at the factory site for operation. Compared to traditional units, this higher level of integration results in a smaller size and smaller footprint. Furthermore, the modular structure is mobile and can even be transported by vehicle. There is virtually no on-site civil construction and minimal on-site installation. Only simple on-site assembly of the modules is required, resulting in a very short construction period and high site adaptability. This system can provide safe and reliable electricity or heat to remote areas such as isolated islands, mines, and high-altitude cold regions where infrastructure is relatively incomplete and there is no reliable external power supply.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0027] Example 1

[0028] The mobile nuclear energy equipment of this embodiment is divided into multiple modules based on functions, which can be transported independently and connected to each other to form a whole, including a primary circuit system module 1 and a working module 2. Figure 1 As shown, the primary-loop system module 1 is integrally encapsulated by a shielding body 15, and the primary-loop system module 1 is internally integrated with: a stack body 11 for generating heat; a primary-loop pipe 12, connected between the stack body 11 and the intermediate heat exchanger 13; a first fan 14, arranged on the primary-loop pipe 12, for driving the primary-loop medium in the primary-loop pipe 12 to absorb the heat of the stack body 11 and transport it to the intermediate heat exchanger 13; the intermediate heat exchanger 13, for exchanging heat between the primary-loop medium and the working medium of the working module 2; the working module 2 and the primary-loop system module 1 are detachably docked, for supplying energy through the working medium after heat exchange in the intermediate heat exchanger 13.

[0029] Through its innovative modular architecture, this device significantly enhances the engineering practicality and adaptability of mobile nuclear energy equipment while ensuring nuclear safety. Specifically, the centralized encapsulation of radioactive components such as the reactor body 11, primary-circuit piping 12, and intermediate heat exchanger 13 within the shield 15 enables centralized management of radiation protection and forms physical isolation. This avoids the redundant installation of protective layers across multiple modules, significantly reduces the risk of radiation exposure for maintenance personnel in the working module 2, and effectively confines radioactive materials to independent, enclosed units in the event of an accident. Furthermore, the modular division fully considers the engineering requirements for transportation and deployment. The primary-circuit system module 1 utilizes a compact, integrated design that can be transported using nuclear facility transportation equipment, while the working module 2, because it contains no radioactive components, can be transported according to conventional industrial equipment standards. This not only breaks through the volume limitations of traditional nuclear facility overall transportation but also significantly reduces transportation costs.

[0030] This functionally decoupled modular division further enhances the system's flexibility and scalability. The primary system module 1 and the working module 2 serve as the nuclear reaction section and the energy conversion section, respectively. Physical separation allows the two to form independent functional units, making their design, production, and fabrication more independent and enabling independent repair and replacement. Furthermore, modular division of labor significantly optimizes construction efficiency, enabling the parallel production of the two modules. On-site deployment requires only modular quick docking, making it particularly suitable for time-sensitive scenarios such as emergency energy supply and deployment in remote areas.

[0031] This equipment integrates components that were once complex and cumbersome and required on-site installation in sequence into modularized settings based on their functions. These components can then be docked and assembled at the plant site for operation. The modularization of the previous nuclear island and conventional island allows for a smaller footprint and a higher degree of integration compared to traditional units. Furthermore, the modular structure is mobile and can even be transported by vehicle. There is virtually no on-site civil construction and minimal on-site installation. Only simple on-site assembly of the modules is required, resulting in a very short construction period and high site adaptability. It can provide safe and reliable electricity or heat to remote areas such as isolated islands, mines, and high-altitude cold regions where infrastructure is relatively incomplete and there is no reliable external power supply.

[0032] In this embodiment, the equipment can be used in the field of nuclear power plant design and construction technology, and can be called a mobile nuclear energy treasure. This nuclear energy treasure is a micro-reactor nuclear energy device. Different from existing large nuclear power plants and small reactors, its thermal power is about 5MWe. The overall structure is simple, which can reduce the overall investment. It is highly flexible and has the characteristics of mobile deployment. It can also provide heat and power generation according to the needs of different regions.

[0033] In this embodiment, the interior space of the shield 15 is formed into a narrow, rectangular chamber 151. The stack body 11, primary-circuit piping 12, and intermediate heat exchanger 13 are arranged sequentially along the length of the rectangular chamber 151 from the first end to the second end, so that the stack body 11 and intermediate heat exchanger 13 are located at both ends of the rectangular chamber 151. A control interface for the stack body 11 is provided at the first end, adjacent to the stack body 11, for controlling the reactivity of the stack body 11 via external equipment. A docking interface 3 for the intermediate heat exchanger 13 is provided at the second end, adjacent to the intermediate heat exchanger 13, for docking with a working module 2. In this layout, the components are arranged linearly along the length of the chamber in a predetermined order, forming a unidirectional heat transfer path for the primary-circuit system from the heat source of the stack body 11 to the heat exchange terminal. This spatial sequence optimizes the heat transfer efficiency of the primary-circuit medium. The stack body 11 and the intermediate heat exchanger 13 that need to be docked with the external equipment components of the module are distributed at both ends respectively, so that the control end and the energy output end are fully separated, which facilitates the connection of the intermediate heat exchanger 13 with the working module 2 (through the secondary loop pipeline 16 with the thermoelectric conversion system module 21 and the heat transfer module 22). This not only avoids cross-interference between signals and lines, but also allows the working module 2 to be completely away from the radioactive control area when docking, and spatially isolates the physical contact between routine operation and maintenance operations and the nuclear system.

[0034] The first fan 14 is located in the space beside the primary-circuit pipe 12, between the stack body 11 and the intermediate heat exchanger 13. This not only utilizes the redundant space in the middle of the chamber to achieve a compact layout, but also reduces the fluid transmission pressure loss by shortening the length of the primary-circuit pipe 12 itself and the connection distance between the first fan 14 and the primary-circuit pipe 12. In this embodiment, the first fan 14 is a helium-based fan, and the corresponding primary-circuit medium is helium.

[0035] Overall, this linear layout within the rectangular chamber 151 also gives the shield 15 modules a regular geometric shape, facilitating both securing and protecting them on transport vehicles. The externally positioned end interfaces also enable quick docking—the working module 2 only needs to be axially connected to the end face of the shield 15 along the length of the chamber to complete system integration, significantly enhancing the ease of on-site assembly. Furthermore, not only are the ends equipped with convenient connection interfaces, but each device is closely adjacent to the side walls of the rectangular chamber 151, facilitating the layout of contact points for power and control cables.

[0036] In this embodiment, the longitudinal direction of the rectangular chamber 151 is arranged horizontally. The reactor body 11 includes a reactor vessel 111 and a control rod drive structure 112. The reactor vessel 111 is arranged horizontally within the rectangular chamber 151 in a horizontal configuration. The control rod drive structure 112 is arranged between the control interface and the reactor vessel 111 and can be moved horizontally by external equipment to control the reactivity of the reactor vessel 111, thereby adjusting thermal power, starting, and performing emergency shutdowns. The low profile of the horizontal layout effectively reduces the vertical height of the module, optimizing the position of the mobile center of gravity and allowing the replacement of fuel assemblies within the reactor vessel 111 to bypass the top-lifting method of traditional vertical reactors. The horizontal layout allows for side-by-side refueling, reducing the lifting height of the fuel assemblies, facilitating maintenance, and improving the convenience and accuracy of refueling operations. The control rod drive structure 112 is arranged in the horizontal direction to further enhance the system integration. It also enables the control rod drive mechanism (external equipment) to achieve reactive control through lateral movement, without the need for high-altitude working platforms, making operation more convenient.

[0037] In this embodiment, the primary-loop piping 12 comprises an inner tube and an outer tube. The outer diameter of the inner tube is smaller than the inner diameter of the outer tube, and the inner tube is sleeved inside the outer tube. The inner tube connects the stack body 11 and the intermediate heat exchanger 13, while the outer tube connects the first fan 14 and the stack body 11. The first fan 14 drives the primary-loop medium along the outer tube into the stack body 11, where it absorbs heat and is then transported along the inner tube to the intermediate heat exchanger 13. A cooling pipeline connecting from the outer tube to the inner tube can be provided within the stack body 11, and a heat exchange pipeline connecting from the inner tube to the outer tube can be provided within the intermediate heat exchanger 13. The primary-loop piping 12 is configured as a sleeve-and-sleeve structure, which reduces the length and number of pipes, further achieving a compact layout, reducing volume and weight, and enhancing mobility. Specifically, the coaxial sleeve connection of the inner tube and the outer tube forms a reverse double channel for medium flow: the outer tube serves as the pressurized delivery path on the cold side, and the first fan 14 drives the first-loop medium to be injected into the stack body 11 to absorb fission heat; the high-temperature first-loop medium after heating flows back through the inner tube to the intermediate heat exchanger 13 to release heat energy. The internal and external circulation constructs a complete circuit in a limited space.

[0038] In this embodiment, the primary system module 1 and the working module 2 are connected via a secondary pipeline 16 to enable the circulation of working medium. A portion of the secondary pipeline 16 is located within the primary system module 1, with one end connected to the intermediate heat exchanger 13 and the other end connected to the end surface of the primary system module 1 to form a docking interface 3. Another portion of the secondary pipeline 16 is located within the working module 2, with one end connected to the working component of the working module 2 and the other end connected to the end surface of the working module 2 to form a docking interface 3. The docking interface 3 of the working module 2 docks with the docking interface 3 of the primary system module 1, integrating the secondary pipeline 16. Specifically, in this embodiment, symmetrically distributed docking interfaces 3 are provided on the end surfaces of the primary system module 1 and the working module 2, physically splitting the secondary pipeline 16 into two independent pipe sections, the nuclear side and the conventional side. This split pipeline architecture maintains the thermodynamic integrity of the secondary system while achieving absolute separation between the radioactive area and the conventional operating area.

[0039] In this embodiment, the secondary-circuit pipeline 16 includes parallel cold and hot sections, respectively, for circulating the working medium before and after heat exchange. The docking interface 3 of the working module 2 docks with the docking interface 3 of the primary-circuit system module 1, allowing the cold sections of the secondary-circuit pipeline 16 to dock with each other, and the hot sections to dock with each other. The intermediate heat exchanger 13 includes a heat exchange pipeline connecting the cold section to the hot section, and the working components of the working module 2 include a working pipeline connecting the hot section to the cold section, ensuring the circulation of the working medium. In this embodiment, the process pipeline docking interfaces 3 between modules can be connected using quick connectors. The working medium can be a fluid such as air or water.

[0040] In this embodiment, the working modules 2 are divided into two categories, namely, a thermoelectric conversion system module 21 and a heat transfer module 22. The thermoelectric conversion system module 21 is used to use the working medium after heat exchange to perform work and power supply, and the heat transfer module 22 is used to use the working medium after heat exchange to provide heat. Either the thermoelectric conversion system module 21 or the heat transfer module 22 is connected to the primary system module 1.

[0041] When the current area (user) where this device is used needs power supply, the secondary circuit pipe 16 of the primary circuit system module 1 is connected to the secondary circuit pipe 16 of the thermoelectric conversion system module 21, the cold section is connected to the cold section, and the hot section is connected to the hot section. Figure 2As shown, in this embodiment, the thermoelectric conversion system module 21 includes a second fan 211, a turbine 212, and a generator 213. The second fan 211 is connected to the turbine 212, driving the working medium into the primary circuit system module 1 for heat exchange with the primary circuit medium in the intermediate heat exchanger 13, and delivering the heat-exchanged working medium to the turbine 212. The turbine 212 is connected to the generator 213, which drives the generator 213 to generate electricity under the drive of the heat-exchanged working medium. During power generation, the secondary circuit air (working medium) is driven by the second fan 211 into the intermediate heat exchanger 13. The high-temperature air after heat exchange enters the turbine 212, which rotates to drive the generator 213 to generate electricity.

[0042] When the current area (user) needs heating, the secondary circuit pipe 16 of the primary circuit system module 1 is connected to the secondary circuit pipe 16 of the heat transfer module 22, the cold section is connected to the cold section, and the hot section is connected to the hot section. Figure 3 As shown, in this embodiment, the heat transfer module 22 includes a third fan 221, a steam generator 222, and a tertiary circuit pipeline 223. The third fan 221 is connected to the steam generator 222 and is used to drive the working medium into the primary circuit system module 1, where it exchanges heat with the primary circuit medium in the intermediate heat exchanger 13 and then delivers the heat-exchanged working medium to the steam generator 222. The steam generator 222 is connected to the hot end via the tertiary circuit pipeline 223, where the tertiary circuit medium in the tertiary circuit pipeline 223 exchanges heat with the heat-exchanged working medium before being supplied to the hot end. When generating heat, the secondary circuit air is driven into the intermediate heat exchanger 13 by the third fan 221. The high-temperature air after heat exchange enters the secondary circuit steam generator 222. The water (tertiary circuit medium) in the tertiary circuit pipeline 223 enters the steam generator 222, absorbs heat, and evaporates, providing steam to the user, thereby providing heat.

[0043] In this embodiment, the mobile nuclear energy equipment further includes an electrical instrument auxiliary system module 4, such as Figure 4 As shown, the electrical instrument auxiliary system module 4 is internally integrated with:

[0044] The electrical cabinet 41 is connected to each module and is used to supply power to the components inside the module;

[0045] The instrumentation and control cabinet 42 is connected to each module and is used to control the operation of the components within the module;

[0046] The primary-loop medium regulating system 43 is connected to the primary-loop pipeline 12 and is used to regulate the primary-loop medium state. The primary-loop medium regulating system 43 specifically includes a helium filling and exhausting system 431, which is used to regulate the helium pressure and replenish leaked helium. By adjusting the helium filling rate of the helium filling and exhausting system 431, the primary-loop helium filling amount can be changed, the helium turbine power can be adjusted, or the heat exchange amount can be adjusted. When the reactor needs to be shut down, the helium filling and exhausting system 431 can also be used to reduce the filling amount to the primary-loop pipeline 12 pressure close to normal pressure. It also includes a helium purification system 432, which is used to purify contaminated helium, control the chemical impurity content of helium in the primary-loop and external helium supply and storage system tanks, maintain the purity of helium, prevent corrosion to components, and control gaseous fission products to reduce the radioactivity level in helium;

[0047] The first fan regulating system 44 , specifically a main helium fan shaft seal cooling system, is connected to the first fan 14 and is used to provide shaft sealing and cooling for the first fan 14 .

[0048] In this embodiment, the electrical cabinet 41, the instrumentation cabinet 42, the primary circuit medium regulating system 43 and the first fan regulating system 44 are arranged in sequence along a straight line. Figure 4 As shown, the electrical cabinet 41 and instrumentation control cabinet 42 are located on the west side, while the helium filling and exhaust system 431, helium purification system 432, and main helium blower shaft seal cooling system are located on the east side. This achieves spatial separation between the process area and the electrical and instrumentation area. Cables are routed from the west side to connect to other modules, while process pipelines are routed from the east side to connect to other modules, facilitating quick pipeline connection and planning.

[0049] In general, the equipment of this embodiment includes four major modules: the primary system module 1, the electrical and instrumentation auxiliary system module 4, the thermoelectric conversion system module 21, and the heat transfer module 22. The components in all four modules are arranged horizontally, facilitating maintenance and replacement. This also reduces the overall module height, facilitating transportation, improving mobility, and facilitating the connection of pipelines (process piping and cables). The primary system module 1 is radioactive and is housed within a shield 15 to prevent leakage of radioactivity. Helium, driven by a first fan 14, enters the reactor vessel 111 through the outer casing of the primary pipeline 12. After absorbing heat, the helium enters the inner casing and enters the intermediate heat exchanger 13, transferring heat to the secondary pipeline 16. The equipment offers advantages such as the ability to be used for both power generation and heating, strong mobility, high site adaptability, rapid deployment, and the lack of civil engineering.

[0050] When the service application area requires electricity, the intermediate heat exchanger 13 of the primary circuit system module 1 is connected to the secondary circuit pipeline 16 of the thermoelectric conversion system module 21. The electrical cables, control cables, and measurement cables in the electrical and instrumentation auxiliary system module 4 are connected to the components of the primary circuit system module 1 and the thermoelectric conversion system module 21, respectively. The remaining auxiliary system pipelines are connected to the components of the primary circuit system module 1 and the thermoelectric conversion system module 21, respectively. The electricity generated by the thermoelectric conversion system module 21 can be directly transmitted to an off-site substation.

[0051] When heating is needed in the service area, the intermediate heat exchanger 13 of the primary circuit system module 1 is connected to the secondary circuit pipeline 16 of the heat transfer module 22. The electrical, control, and measurement cables in the electrical and instrumentation auxiliary system module 4 are connected to the components of the primary circuit system module 1 and the heat transfer module 22, respectively. The remaining auxiliary system pipelines are also connected to the components of the primary circuit system module 1 and the heat transfer module 22, respectively. The heat energy generated by the heat transfer module 22 is directly connected to the user for heating.

[0054] Specifically, when the nuclear energy system is a power generation system, a fire pump room is set up in the system plant to provide water in case of fire, a joint pump room is used to provide cold source, and a desalted water plant is used to provide desalted water. In addition, an air compressor room is set up to provide high-pressure gas, an office building is used for staff offices, and a substation is set up for grid connection, as well as pipelines and cables for connecting movable nuclear energy equipment with the equipment in the above sub-items.

[0055] When the nuclear energy system is used for energy storage, it can be connected to batteries, generating electricity to charge them. Alternatively, it can be connected to molten salt, generating heat that can be transferred to the molten salt system. In this case, the plant requires a fire pump room to provide water in the event of a fire, a combined pump room to provide cooling, a desalted water plant to provide desalted water, an air compressor room to provide high-pressure air, an office building for staff, and piping and cabling to connect the mobile nuclear energy equipment to the equipment listed in the above sub-items.
