Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of nuclear power generation, and in particular, to a mobile reactor power supply. Background Art
[0002] Most of the currently operating nuclear power plants are traditional large-scale nuclear power plants with an output electric power greater than 1 GW, which have a long construction period and high construction costs. The new generation of nuclear power technologies tend to develop towards small size and modular construction. The International Atomic Energy Agency defines a reactor with an output electric power below 300 MW as a small reactor. Compared with traditional large reactors, small reactors can be used as a decentralized energy supply system to meet the power supply in remote areas where the traditional power grid cannot reach.
[0003] In the existing technical solutions, a small reactor is divided into a reactor system module, an auxiliary system module, and a power generation system module. After transporting each module to the destination by three trucks and connecting them with corresponding connecting pipelines, power generation is carried out. However, such a solution has the following problems:
[0004] 1. The reactor adopts a pressurized water reactor type with water as the coolant. Therefore, in addition to the reactor core that releases heat by nuclear fission, the reactor system module also needs to include equipment such as control rod drive mechanisms, pressurizers, and steam generators, which are used to control the reactivity of the reactor core, stabilize the system pressure, and transfer the heat of the reactor core. This makes the equipment in the reactor system module numerous and the structure complex, which is not conducive to the maintenance and control of the mobile reactor.
[0005] 2. In addition to one truck transporting the reactor system module, another two trucks are required to transport the auxiliary system module and the power generation system module respectively. A total of three trucks are used for transportation, resulting in poor mobility and a large floor area.
[0006] 3. The three systems need to be placed side by side, with the reactor system module in the middle. The modules are directly connected by pipes exposed outside, resulting in poor safety. Before power generation, the reactor needs to be adjusted from the horizontal state during transportation to the vertical state. This requires the reactor design to not only meet the requirements for normal use in the vertical state but also meet the transportation requirements in the horizontal state.
[0007] In addition, nuclear reactors with a power level of 1 MW - 50 MW, although relatively small in volume and power, have a wide range of applications. In the prior art, the structural layout of nuclear reactors at this power level is as Figure 4 shown. The fluid flowing through the reactor core 60' is heated and then enters the internal heat pool 110'. The fluid in the internal heat pool 110' is cooled by the heat exchanger 200' and then enters the external heat pool 120'. The cold fluid in the external heat pool 120' is heated by the reactor core 60' and re-enters the internal heat pool 110'. The whole process is realized by natural circulation or the driving head of a pump.
[0008] However, in the prior art, nuclear reactors with a power level of 1MW - 50MW are large in volume and weight, not convenient for mobile transportation, which limits their application scope and application diversity. SUMMARY OF THE INVENTION
[0009] The first object of the present invention is to provide a mobile reactor power supply to solve the technical problems of poor mobility and large floor area of existing mobile reactor power supplies.
[0010] The mobile reactor power supply provided by the present invention includes a reactor system. The reactor system includes a reactor core, a coolant, and a turbine. The reactor core is connected to the turbine through a first pipeline. The reactor core is a gas-cooled reactor, and the coolant is a helium-xenon mixed gas.
[0011] The beneficial effects brought by the mobile reactor power supply of the present invention are as follows:
[0012] By selecting a helium-xenon mixed gas as the coolant of the gas-cooled reactor, the number of turbine stages can be reduced, and the size and weight of the turbine are decreased. Moreover, compared with a pressurized water reactor, equipment such as a pressurizer and a steam generator in the pressurized water reactor are eliminated, significantly reducing the size and mass of the reactor system. This makes it possible to install the entire nuclear reactor power supply into an internationally common standard container, which is beneficial to reducing the floor area of the mobile reactor power supply and improving its mobility.
[0013] In a preferred technical solution, the reactor system further includes a compressor, and the compressor is connected to the turbine through a transmission main shaft.
[0014] Connecting the compressor to the turbine through a transmission main shaft can utilize the mechanical energy generated by the action of high-temperature and high-pressure gas on the turbine, and partially use it in the process of compressing the gas, converting it into the pressure energy of the gas entering the subsequent equipment, improving the flow rate and / or pressure of the gas, so as to facilitate increasing the pressure of the gas when entering the subsequent equipment, thereby ensuring the flow rate and pressure of the gas entering the reactor core.
[0015] In a preferred technical solution, the reactor system further includes a regenerator. The regenerator includes a hot-side inlet, a hot-side outlet, a cold-side inlet, and a cold-side outlet. The hot-side inlet is connected to the turbine, the cold-side inlet is connected to the compressor, and the cold-side outlet is connected to the reactor core.
[0016] By setting up a regenerator, part of the energy of the high-temperature and high-pressure gas after passing through the turbine can be recovered. This can not only reduce the burden of specifically cooling the gas after it has done work on the turbine, but also utilize this part of the heat to increase the temperature of the fluid before entering the reactor core, enabling the reactor core to be in a suitable temperature range to improve the heat absorption efficiency of the gas when passing through the reactor core.
[0017] In a preferred technical solution, the regenerator is located between the compressor and the core.
[0018] By arranging the regenerator between the compressor and the core, not only can the distance between the turbine and the regenerator be shortened, the heat loss of the gas flowing from the turbine to the regenerator be reduced, and the temperature at the hot-side inlet of the regenerator be increased, but also the distance between the cold-side outlet of the regenerator and the core can be shortened, the heat loss of the gas flowing from the regenerator to the core be reduced, and the temperature of the gas entering the core be increased.
[0019] In a preferred technical solution, the reactor system further includes a pre-cooler, the inlet of the pre-cooler is communicated with the hot-side outlet, and the outlet of the pre-cooler is communicated with the inlet of the compressor.
[0020] By arranging the pre-cooler, the temperature of the gas passing through the regenerator can be reduced, so that the gas entering the cold-side inlet of the regenerator is within an appropriate temperature range, which is beneficial for the gas entering the core from the cold-side outlet of the regenerator to be within a normal temperature range.
[0021] In a preferred technical solution, the reactor system further includes a pressure-bearing housing, and the core, the turbine, the compressor, the regenerator and the pre-cooler are all located in the pressure-bearing housing.
[0022] The core, the turbine, the compressor, the regenerator and the pre-cooler are all arranged in the pressure-bearing housing and communicated through pipelines. Not only can the above equipment be shielded by the pressure-bearing housing, reducing the external radiation of the mobile reactor power source, but also compared with the prior art solution where the three modules are respectively arranged in one container, there is no need to connect the modules with open-air pipelines, shortening the total length of the pipelines and reducing the possibility of accidents caused by pipeline rupture.
[0023] The second object of the present invention is to provide a mobile reactor power source to solve the technical problems in the prior art that the volume and weight of the nuclear reactor are relatively large, which is not convenient for mobile transportation and limits its application.
[0024] The mobile reactor power source provided by the present invention includes a pressure-bearing housing and a pre-cooler, a compressor, a regenerator, a core and a turbine installed in the pressure-bearing housing, and the power output shaft of the turbine extends out of the pressure-bearing housing; the pressure-bearing housing is airtight.
[0025] The beneficial effects brought by the mobile reactor power source of the present invention are:
[0026] The mobile reactor power supply provided by the present invention arranges the precooler, compressor, recuperator, reactor core, and turbine inside the pressure-bearing shell, thus greatly reducing the volume and weight of the device, enabling the entire device to be transported mobilely by various transportation means, and further realizing cross-regional and diversified applications. In addition, in the mobile reactor power supply of the present invention, there are fewer pipelines, which can effectively reduce the construction and operation costs as well as the risk of pipeline rupture; during operation, since the circulation of the coolant does not require a mechanical pump, it can avoid problems such as manufacturing and transportation brought by the mechanical pump, and the noise of the entire device can also be reduced.
[0027] In a preferred technical solution, the precooler, the compressor, the recuperator, the reactor core, and the turbine are arranged in sequence along the horizontal direction.
[0028] Arranged in sequence along the horizontal direction, the height of the mobile reactor power supply is reduced, further improving the convenience of moving and transporting, and being beneficial to further expanding the use area and use diversity.
[0029] In a preferred technical solution, the precooler, the compressor, the recuperator, the reactor core, and the turbine are coaxially arranged.
[0030] By adopting the method of coaxially arranging the above components, the circulation flow of the coolant inside the pressure-bearing shell is generally centrosymmetric with the common axis of each component as the axis of symmetry. The resistance of each component to the coolant is small, and the circulation flow is smooth, thereby being able to improve the energy conversion rate.
[0031] In a preferred technical solution, the cavity of the pressure-bearing shell is cylindrical, and the cavity is consistent with the length direction of the pressure-bearing shell.
[0032] In this technical solution, the shape of the cavity of the pressure-bearing shell matches the shape of the coolant circulation flow, and the utilization rate of the space inside the cavity is high; in addition, the cavity wall also plays a role in limiting and guiding the coolant, making the flow of the coolant more concentrated and regular, which is beneficial to improving the energy conversion rate.
[0033] In a preferred technical solution, the coolant inside the mobile reactor power supply performs a Brayton cycle.
[0034] When the coolant performs a Brayton cycle, the coolant can experience four processes of isentropic compression by the compressor, isobaric heating by the reactor core, isentropic expansion by the turbine, and isobaric heat rejection by the precooler in each cycle. The output power range of the mobile reactor power supply is wide, which can range from dozens of kilowatts to megawatts.
[0035] In a preferred technical solution, the precooler, the compressor, the recuperator, the reactor core, and the turbine are arranged in sequence along the length direction of the pressure-bearing shell.
[0036] The pre-cooler, compressor, recuperator, reactor core and turbine are sequentially arranged along the length direction of the pressure-bearing housing, which is beneficial to making the structure of the reactor system more compact, further reducing the volume and further reducing the space occupation, thereby being more conducive to mobile transportation.
[0037] In a preferred technical solution, the outer peripheral contour of the pressure-bearing housing is in a cuboid shape or a cylindrical shape.
[0038] When the outer peripheral contour of the pressure-bearing housing adopts a cuboid shape, it is beneficial to cooperate with the flat transportation bearing surface and installation bearing surface, improving the overall stability of the reactor system. When the pressure-bearing housing adopts a cylindrical shape and the internal cavity of the pressure-bearing housing is cylindrical, it is beneficial to maintain the thickness consistency of the pressure-bearing housing, reduce the stress concentration of the pressure-bearing housing, and improve the strength of the pressure-bearing housing.
[0039] In a preferred technical solution, it further includes a generator, and the generator is connected to the turbine through a transmission main shaft.
[0040] Connecting the turbine to the generator through the transmission main shaft can convert the mechanical energy of the turbine into electrical energy generated by the generator, supplying power to remote areas that cannot be reached by the traditional power grid.
[0041] In a preferred technical solution, it further includes a container, and both the generator and the pressure-bearing housing are installed in the same container.
[0042] By installing both the generator and the pressure-bearing housing in the same container, it is beneficial to improve the mobility of the mobile reactor power source, not only reducing the transportation cost, but also shortening the assembly time after transportation. In addition, it can also reduce the site area required for placing the mobile reactor power source, improving the flexibility of use. In addition, compared with the solution using three containers, in both the transportation state and the power generation state, the mobile reactor power source can always remain in a flat state, without the need to rotate the container before power generation, without having to meet the requirements for normal use in the vertical placement state and the transportation requirements in the flat placement state, reducing the design, manufacturing and transportation difficulties of the mobile reactor power source.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0051] Embodiment 1:
[0052] Figure 1 A schematic diagram of the structure of a mobile reactor power supply provided in Embodiment 1 of the present invention; Figure 2 This is a three-dimensional schematic diagram of a mobile reactor power supply provided in the first embodiment of the present invention, in which part of the skin of the container is rolled up, and the wall thickness of the pressure shell is omitted, and only the frame of the pressure shell is drawn. Figure 1 and Figure 2 As shown, the mobile reactor power supply provided in this embodiment includes a core 60 and a turbine 70. The core 60 is connected to the turbine 70 through a first pipeline. The core 60 is a gas-cooled reactor, and the gas-cooled reactor uses a helium-xenon mixed gas as a coolant.
[0053] By selecting a helium-xenon mixed gas as the coolant for the gas-cooled reactor, the number of stages of the turbine 70 can be reduced, and the size and weight of the turbine 70 can be reduced. Moreover, compared with the pressurized water reactor, the pressurizer, steam generator and other equipment in the pressurized water reactor are omitted, which significantly reduces the size and weight of the reactor system. It makes it possible to install the entire nuclear reactor power supply in an internationally used standard container, which is conducive to reducing the footprint of the mobile reactor power supply and improving its mobility.
[0054] like Figure 1 and Figure 2As shown, in the preferred technical solution, a compressor 40 is further included, and the compressor 40 is connected to the turbine 70 through a transmission main shaft 80.
[0055] Connecting the compressor 40 to the turbine 70 through the transmission main shaft 80 can partially utilize the mechanical energy generated by the action of high-temperature and high-pressure gas on the turbine 70 during the gas compression process, converting it into the pressure energy of the gas entering the subsequent equipment, improving the flow rate and / or pressure of the gas, so as to facilitate increasing the pressure of the gas when entering the subsequent equipment, thereby ensuring the flow rate and pressure of the gas entering the core 60.
[0056] It should be noted that although the transmission main shaft 80 passes through the core 60, since in this solution, the pre-cooler 30, compressor 40, recuperator 50, core 60, and turbine 70 are jointly arranged in the pressure-bearing housing 20 for shielding, nuclear leakage from the core 60 to the outside will not be caused.
[0057] As Figure 1 and Figure 2 shown, in the preferred technical solution, a recuperator 50 is further included. The recuperator 50 includes a hot-side inlet, a hot-side outlet, a cold-side inlet, and a cold-side outlet. The hot-side inlet is communicated with the turbine 70, the cold-side inlet is communicated with the compressor 40, and the cold-side outlet is communicated with the core 60.
[0058] By providing the recuperator 50, part of the energy of the high-temperature and high-pressure gas after passing through the turbine 70 can be recovered. This can not only reduce the burden of specifically cooling the gas after doing work on the turbine 70, but also utilize this part of the heat to increase the temperature of the fluid before entering the core 60, enabling the core 60 to be in an appropriate temperature range to improve the heat absorption efficiency of the gas when passing through the core 60. Moreover, by inputting the gas compressed by the compressor 40 into the cold side of the recuperator 50, under the condition of the same amount of substance input to the recuperator 50, the gas flow rate can be reduced, thereby reducing the volume of the recuperator 50, which is conducive to reducing the volume of the reactor system and even the mobile reactor power supply.
[0059] As Figure 1 and Figure 2 shown, in the preferred technical solution, the recuperator 50 is located between the compressor 40 and the core 60.
[0060] By arranging the recuperator 50 between the compressor 40 and the core 60, not only can the distance between the turbine 70 and the recuperator 50 be shortened, reducing the heat loss of the gas flowing from the turbine 70 to the recuperator 50 and increasing the temperature of the hot-side inlet of the recuperator 50, but also the distance between the cold-side outlet of the recuperator 50 and the core 60 can be shortened, reducing the heat loss of the gas flowing from the recuperator 50 to the core 60 and increasing the temperature of the gas entering the core 60.
[0061] It should be noted that although the recuperator 50 is arranged between the compressor 40 and the reactor core 60, which will cause the middle part of the recuperator 50 to be penetrated by the transmission main shaft 80 and may cause heat loss accordingly. However, considering the reduction of heat loss brought about by shortening the pipeline length, it is still worthwhile to let the rotating main shaft penetrate the recuperator 50. In particular, since the transmission main shaft 80 is connected to the impeller in the turbine 70 and the impeller is impacted by high-temperature and high-pressure liquid, the temperature is very high, and the temperature of the transmission main shaft 80 leading to the reactor core 60 and the side of the recuperator 50 is also not low. Even if the relatively high-temperature transmission main shaft 80 passes through the recuperator 50, no significant heat loss will occur.
[0062] As Figure 1 and Figure 2 shown, in the preferred technical solution, it further includes a pre-cooler 30. The inlet of the pre-cooler 30 is communicated with the hot-side outlet, and the outlet of the pre-cooler 30 is communicated with the inlet of the compressor 40.
[0063] By arranging the pre-cooler 30, the temperature of the gas passing through the recuperator 50 can be reduced, so that the gas entering the cold-side inlet of the recuperator 50 is within an appropriate temperature range, which is conducive to the gas entering the reactor core 60 from the cold-side outlet of the recuperator 50 being within a normal temperature range.
[0064] As Figure 1 and Figure 2 shown, in the preferred technical solution, it further includes a pressure-bearing housing 20. The reactor core 60, the turbine 70, the compressor 40, the recuperator 50 and the pre-cooler 30 are all located in the pressure-bearing housing 20.
[0065] The reactor core 60, the turbine 70, the compressor 40, the recuperator 50 and the pre-cooler 30 are all arranged in the pressure-bearing housing 20 and are communicated through pipelines. This can not only shield the above-mentioned equipment by the pressure-bearing housing 20 and reduce the external radiation of the mobile reactor power supply, but also, compared with the prior art solution where the three modules are respectively arranged in a container 10, there is no need to connect the modules with open-air pipelines, shortening the total length of the pipelines and reducing the possibility of accidents caused by pipeline rupture.
[0066] As Figure 1 and Figure 2 shown, in the preferred technical solution, the pre-cooler 30, the compressor 40, the recuperator 50, the reactor core 60 and the turbine 70 are arranged in sequence along the horizontal direction. In this setting form, the height of the mobile reactor power supply is low, further improving the convenience of handling and transportation and being conducive to further expanding the use area and use diversity.
[0067] As Figure 1 and Figure 2As shown, in the preferred technical solution, the precooler 30, the compressor 40, the recuperator 50, the reactor core 60, and the turbine 70 are coaxially arranged. With this arrangement, the circulation flow of the coolant within the pressure-bearing housing 20 is generally centrosymmetric with the common axis of each component as the axis of symmetry. The resistance forces exerted on the coolant by each component are small, and the circulation flow is smooth, thereby enabling the improvement of the energy conversion rate.
[0068] As Figure 1 and Figure 2 As shown, in the preferred technical solution, the pressure-bearing housing 20 is in a long strip shape, and the precooler 30, the compressor 40, the recuperator 50, the reactor core 60, and the turbine 70 are arranged along the length direction of the pressure-bearing housing 20. With this arrangement, the structure of the mobile reactor power supply is more compact, the volume is further reduced, and the space occupation is further decreased, thus being more conducive to mobile transportation.
[0069] In the preferred technical solution, the cavity of the pressure-bearing housing 20 is in a cylindrical shape, and the cavity is consistent with the length direction of the pressure-bearing housing 20. In this setting form, the shape of the cavity of the pressure-bearing housing 20 matches the shape of the coolant circulation flow, and the utilization rate of the space within the cavity is high; in addition, the cavity wall also plays a role in limiting and guiding the coolant, making the flow of the coolant more concentrated and regular, which is conducive to improving the energy conversion rate.
[0070] In the preferred technical solution, the coolant within the mobile reactor power supply undergoes a Brayton cycle. More specifically, in each cycle, the coolant can experience four processes: isentropic compression by the compressor 40, isobaric heating by the reactor core 60, isentropic expansion by the turbine 70, and isobaric heat rejection by the precooler 30. In this setting form, the output power range of the mobile reactor power supply is wide, which can range from dozens of kilowatts to megawatts.
[0071] As Figure 1 and Figure 2 As shown, in the preferred technical solution, the precooler 30, the compressor 40, the recuperator 50, the reactor core 60, and the turbine 70 are arranged in sequence along the length direction of the pressure-bearing housing 20.
[0072] Arranging the precooler 30, the compressor 40, the recuperator 50, the reactor core 60, and the turbine 70 in sequence along the length direction of the pressure-bearing housing 20 is conducive to making the structure of the reactor system more compact, further reducing the volume, and further decreasing the space occupation, thus being more conducive to mobile transportation.
[0073] As Figure 1 and Figure 2 As shown, in the preferred technical solution, the outer peripheral contour of the pressure-bearing housing 20 is in a cuboid shape or a cylindrical shape.
[0074] The outer peripheral contour of the pressure-bearing housing 20 is in the shape of a cuboid, which is conducive to mating with the flat transportation bearing surface and installation bearing surface, improving the overall stability of the reactor system, and is particularly suitable for the case where the pressure-bearing housing 20 is installed in the container 10 in this embodiment. When the inner cavity of the pressure-bearing housing 20 is cylindrical, using a cylindrical pressure-bearing housing 20 is conducive to maintaining the consistency of the thickness of the pressure-bearing housing 20, reducing the stress concentration of the pressure-bearing housing 20, and improving the strength of the pressure-bearing housing 20.
[0075] Embodiment 2:
[0076] Figure 3 Schematic diagram of the structure of the reactor system in the mobile reactor power supply provided for Embodiment 2; as Figure 3 shown, in the preferred technical solution, it further includes a generator 90, and the generator 90 is connected to the turbine 70 through a transmission main shaft 80.
[0077] Connecting the turbine 70 to the generator 90 through the transmission main shaft 80 can convert the mechanical energy of the turbine 70 into electrical energy generated by the generator 90 to supply power to remote areas that cannot be reached by the traditional power grid.
[0078] As Figure 3 shown, in the preferred technical solution, it further includes a container 10, and both the generator 90 and the pressure-bearing housing 20 are installed in the same container 10.
[0079] By installing both the generator 90 and the pressure-bearing housing 20 in the same container 10, it is conducive to improving the mobility of the mobile reactor power supply, not only reducing the transportation cost, but also shortening the assembly time after transportation. In addition, it can also reduce the site area required for placing the mobile reactor power supply and improve the flexibility of use. In addition, compared with the solution using three containers, in both the transportation state and the power generation state, the mobile reactor power supply can always remain in a flat state, without the need to rotate the container 10 before power generation, without having to meet the requirements for normal use in the vertical placement state and the transportation requirements in the flat placement state, reducing the design, manufacturing, and transportation difficulties of the mobile reactor power supply.
[0080] Existing internationally common standard containers are divided into four series: A, B, C, and D. Their widths are all 8 ft (about 2,438.4 mm). The minimum length is 10 ft (about 3,048 mm) for the D series, and the minimum height is about 8 ft. The most commonly used containers for land transportation are the ICC type of the C series and the IAA type of the A series. The former has dimensions of 20 * 8 * 8 ft, and the latter has dimensions of 40 * 8 * 8 ft 6 in. Here, "ft" refers to feet, and "in" refers to inch. The rated mass of the mobile reactor power supply in this embodiment is 30.48 t. The size and weight of the entire mobile power supply are within the range that can be accommodated by internationally common standard containers. After being loaded into the container 10, it can be transported to the designated location for power supply by means of equipment such as trucks, trains, ships, and airplanes.
[0081] The operating principle of this embodiment is as follows:
[0082] As Figure 3 shown, the helium-xenon mixed gas flows through the reactor core 60, taking away the heat released by the fuel fission in the reactor core 60. The heated coolant gas enters the turbine 70 to expand and do work. The impeller of the turbine 70 rotates, driving the transmission main shaft 80 of the generator 90 to rotate. Through the generator 90, part of the energy is converted into electrical energy, which can not only supply power to remote areas but also be used for disaster relief, regional power supply and heating, seawater desalination, and hydrogen production. At the same time, the turbine 70 also drives the compressor 40 to rotate through the transmission main shaft 80, providing power for the compression of the gas. The coolant gas flowing out of the turbine 70 enters the hot-side inlet of the recuperator 50, providing heat for the coolant gas entering the cold-side inlet of the recuperator 50 before entering the reactor core 60. Then, the coolant flowing out of the hot-side outlet of the recuperator 50 is further cooled by the precooler 30 and then enters the compressor 40 to compress the volume. After being compressed by the compressor 40, the coolant gas at the outlet of the compressor 40 enters the cold-side inlet of the recuperator 50, absorbs the heat of the gas on the hot side of the recuperator 50, and after the temperature rises, flows into the reactor core 60, forming a closed loop.
