Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power plants, and in particular to a layout structure of a magnetic confinement fusion power plant. Background Art

[0002] Nuclear fusion energy is considered an important direction for future energy development due to its almost unlimited energy supply and low environmental impact. Magnetic confinement fusion is one of the main ways to achieve controlled nuclear fusion. It uses a strong magnetic field to control high-temperature plasma, allowing the fusion reaction to proceed in a controlled environment, thereby releasing energy safely and efficiently.

[0003] However, the actual application of magnetic confinement fusion technology still faces multiple technical and engineering challenges. In terms of energy conversion, the conversion process from plasma to thermal energy and then to electrical energy is complex, resulting in large energy losses. In terms of material handling and transportation, the supply of nuclear fuel and the treatment of nuclear waste require an efficient logistics system and a complete material flow line. In terms of signal control and monitoring, the control and monitoring of fusion reactions need to rely on a precise signal flow system to effectively process and respond in real time to the dynamic changes of the fusion power plant. In terms of safety, the control of high-energy plasma and the safe handling of nuclear waste place extremely high demands on power plant design, and a comprehensive safety system is needed to ensure operational safety.

[0004] In the existing technology, commercial magnetic confinement fusion power plant solutions usually focus on optimizing the layout inside the nuclear island in order to make the main power plant and other supporting power plants compact. Specifically, auxiliary facilities such as electrical power plants, neutral beam power plants, magnet power plants, heating plants, tritium plants, etc. are generally arranged closely around the main power plant, while the overall planning of other areas within the plant often lacks systematic consideration, which may lead to low resource utilization efficiency and have an adverse impact on the overall operation efficiency of the power plant. Summary of the invention

[0005] In view of this, the present invention provides a magnetic confinement fusion power plant layout structure to solve the problem of poor overall performance of the magnetic confinement fusion power plant.

[0006] In a first aspect, the present invention provides a magnetic confinement fusion power plant arrangement structure, comprising:

[0007] The main engine area is arranged in a rectangular shape. The tritium plant, hot room and waste treatment plant are arranged in sequence along the length direction of the main engine area. The main engine plant is set on one side of the tritium plant.

[0008] The external power generation area is installed on one side of the short side of the main engine area, and the external power generation area is aligned with the main engine plant;

[0009] The power input area is installed on one side of the long side of the host area. The power input area is set close to the host plant, and the host plant is set between the power input area and the tritium factory.

[0010] The layout structure of the magnetic confinement fusion power station is planned and arranged comprehensively after comprehensively considering multiple aspects such as energy conversion, material processing and transportation, and signal control and monitoring. In terms of energy conversion, efficient magnetic confinement fusion reaction is used as the energy source. Its main engine plant, as the core area of ​​fusion reaction, is arranged between the power input area and the tritium plant. It ensures the stable power supply required for the fusion reaction and facilitates the efficient conversion of the huge energy generated by fusion into electrical energy through the main engine plant. The external power generation area is set up next to the short side of the main engine area, realizing the direct and efficient output of the converted electrical energy to the power grid, thereby improving the energy output efficiency of the fusion power station. In terms of material processing and transportation, attention is paid to the effective management and transportation of raw materials and waste required for fusion reactions. As the production base of fusion reaction raw materials, the tritium plant is set at the starting position of the main engine area to facilitate the timely supply of raw materials. The hot chamber and waste treatment plant follow closely behind, ensuring that the waste generated by the fusion reaction can be handled in a timely and safe manner. This streamlined design not only optimizes the transportation path of raw materials and waste, but also improves the efficiency of material processing. In terms of signal control monitoring, by placing the main power plant adjacent to the tritium plant, the signals between the main power plant and the tritium plant can be quickly communicated, improving the accuracy and timeliness of signal transmission and monitoring in the nuclear fusion reaction area, and ensuring the stable operation of the entire fusion power plant. This technical solution uses streamlined design and system integration methods to comprehensively consider energy conversion, material processing and transportation, and signal control monitoring, and comprehensively plans the layout structure of the magnetic confinement fusion power plant, achieving a significant improvement in technical effects and improving the overall performance and reliability of the fusion power plant.

[0015] In an optional embodiment, a power supply area is further included, which is arranged outside the protection area and is arranged on the side of the power input area away from the main host area.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] Combine the following Figure 1 , describing an embodiment of the present invention.

[0025] According to an embodiment of the present invention, on the one hand, a magnetic confinement fusion power station layout structure is provided, including multiple areas such as a main engine area, an external power generation area and a power input area.

[0026] The main engine area is arranged in a rectangular shape. The tritium plant 2, the hot chamber 3 and the waste treatment plant are arranged in sequence along the length direction of the main engine area. The main engine plant 1 is arranged on one side of the tritium plant 2. The external power generation area is installed on one side of the short side of the main engine area, and the external power generation area is aligned with the main engine plant 1. The power input area is installed on one side of the long side of the main engine area, and the power input area is arranged close to the main engine plant 1. The main engine plant 1 is arranged between the power input area and the tritium plant 2.

[0027] The layout structure of the magnetic confinement fusion power station is planned and arranged comprehensively after comprehensively considering multiple aspects such as energy conversion, material processing and transportation, and signal control and monitoring. In terms of energy conversion, efficient magnetic confinement fusion reaction is used as the energy source. Its main engine plant 1 is the core area of ​​fusion reaction and is arranged between the power input area and the tritium plant 2. It ensures the stable power supply required for the fusion reaction and facilitates the efficient conversion of the huge energy generated by fusion into electrical energy through the main engine plant 1. The external power generation area is set up next to the short side of the main engine area, realizing the direct and efficient output of the converted electrical energy to the power grid, thereby improving the energy output efficiency of the fusion power station. In terms of material processing and transportation, attention is paid to the effective management and transportation of raw materials and waste required for fusion reactions. As the production base of fusion reaction raw materials, the tritium plant 2 is set at the starting position of the main engine area to facilitate the timely supply of raw materials. The hot chamber 3 and the waste treatment plant follow closely behind, ensuring that the waste generated by the fusion reaction can be handled in a timely and safe manner. This streamline design not only optimizes the transportation path of raw materials and waste, but also improves the efficiency of material processing. In terms of signal control monitoring, by setting the main engine plant 1 and the tritium plant 2 adjacent to each other, the signals between the main engine plant 1 and the tritium plant 2 can be quickly communicated, improving the accuracy and timeliness of signal transmission and monitoring in the nuclear fusion reaction area, and ensuring the stable operation of the entire fusion power station. This technical solution uses streamlined design and system integration methods to comprehensively consider energy conversion, material processing and transportation, and signal control monitoring, and comprehensively plans the layout structure of the magnetic confinement fusion power station, achieving a significant improvement in technical effects and improving the overall performance and reliability of the fusion power station.

[0028] In one embodiment, the external power generation area is arranged on one side of the main engine area, and a cooling heat exchange area and a desalted water area are respectively arranged on both sides thereof, and the three are arranged in a straight line. This arrangement is intended to optimize the thermoelectric conversion process, and is specifically implemented as follows: the heat energy output from the main engine area is first introduced into the external power generation area, and the external power generation area is converted into steam after absorbing the heat energy through water. Subsequently, the steam drives the steam turbine in the steam turbine plant 27 to rotate, thereby converting the heat energy into mechanical energy. The mechanical energy is then converted into electrical energy through a generator to achieve external output. In order to effectively manage heat emissions and ensure continuous and efficient operation of the equipment, the cooling heat exchange area and the desalted water area are respectively arranged on both sides of the external power generation area. The cooling heat exchange area is responsible for dissipating the heat generated by the steam turbine, while the desalted water area provides purified water to ensure the purity of the water and the stability of the system during the power generation process. This series of designs not only optimizes the efficiency of the thermoelectric conversion process, but also ensures the maximum utilization of energy, and improves the energy conversion efficiency and operational reliability of the entire magnetic confinement fusion power station.

[0029] In one embodiment, it also includes a transfer and hoisting site 37, which adopts a rectangular layout structure to optimize equipment transportation and hoisting operations. Specifically, one long side of the transfer and hoisting site 37 is set up next to the tritium factory 2, which is convenient for the rapid transportation of raw materials and equipment; at the same time, one of its short sides is arranged close to the desalted water area, which is conducive to providing necessary support and cooperation for the desalted water treatment process. One of the long sides on the other two sides of the transfer and hoisting site 37 is planned as an auxiliary facility reserved area. This design reserves sufficient space for the installation and deployment of various auxiliary facilities, such as hoisting equipment, transportation tracks, etc., to support the efficient and rapid movement and processing of equipment to the tritium factory 2 and the desalted water area. It can improve the efficiency of equipment transportation and hoisting, and enhance the flexibility and maintainability of the entire magnetic confinement fusion power station.

[0030] In one embodiment, a radiation isolation wall is also provided to enclose a protection zone, which includes all key functional areas such as the host area, external power generation area, power input area, cooling and heat exchange area, and desalted water area. Areas that may generate radioactivity or have the risk of radioactive material leakage during operation are fully included in the protection zone, thereby ensuring the effective control of high-energy plasma and the safe disposal of nuclear waste. The establishment of a radiation isolation wall not only effectively isolates potential radioactive hazards, but also improves the safety protection level of the entire fusion power station, ensuring the safety of operators and the environment.

[0031] In one embodiment, the design of the cooling and heat exchange area is further optimized, and a circulating water area is added on the side away from the main engine area, and a water replenishment area is configured on one side of the circulating water area. The water replenishment area and the circulating water area are arranged in a linear structure and are located outside the protection area. Such a design is not only convenient for management and maintenance, but also ensures the stable operation of the cooling system. The circulating water area is responsible for providing circulating cooling water for the cooling and heat exchange area, while the water replenishment area is responsible for replenishing fresh water for the circulating water area when necessary. This arrangement structure not only improves the cooling efficiency, but also effectively reduces energy consumption. An alternative implementation scheme is that the water replenishment area and the circulating water area can be arranged in an L-shape or arc shape on both sides of the circulating water area to adapt to different site conditions.

[0032] In one embodiment, the power supply area is arranged outside the protection area and is located on the side of the power input area away from the main host area. This arrangement enables the power input area to be closer to the power supply line point in the main power supply area, thereby facilitating rapid adjustment of the power supply mode to adapt to dynamic changes in the operation of the power station. This improves the flexibility and reliability of power supply and helps reduce power loss.

[0033] In one embodiment, areas such as auxiliary facility reserved area, comprehensive storage area and production service building 41 are planned outside the protection area. These areas provide necessary support and guarantee for the operation of the power plant. The auxiliary facility reserved area reserves space for facilities that may be added in the future; the comprehensive storage area is used to store various spare parts and consumables; and the production service building 41 provides places for office, rest and training. Such a design not only improves the operation and maintenance efficiency of the power plant, but also enhances its scalability and flexibility. These areas can be merged or split according to actual needs to adapt to different power plant scales and needs.

[0034] In one embodiment, a magnet coil production plant and an assembly site 38 are added outside the protection zone. The magnet coil production plant is responsible for producing the magnet coils required for the fusion reaction, while the assembly site 38 is used to assemble the magnet coils with other components. The assembly site 38 is set close to the hot chamber 3, which is convenient for directly transporting the assembled magnet coils to the hot chamber 3 for further processing and treatment. This design not only shortens the production process, but also improves work efficiency.

[0035] In one embodiment, the main engine building 1 and the external power generation area are connected through an energy transmission channel. This design ensures that the energy generated by the fusion reaction can be efficiently transferred to the external power generation area and then converted into electrical energy output. The design of the energy transmission channel not only improves the energy conversion efficiency, but also helps to reduce energy loss.

[0036] In one embodiment, the layout structure design of the magnetic confinement fusion power station fully considers the proximity of functional areas and the convenience of operation. A diagnostic plant 6 is set up next to the tritium plant 2 on the side away from the hot chamber 3. At the same time, the main plant 1 is also arranged adjacent to the diagnostic plant 6, forming a close functional linkage area. This design is intended to optimize the diagnostic process and ensure that the diagnostic plant 6 can efficiently and accurately monitor the key physical parameters in the nuclear reaction process, including temperature, pressure, and radiation level, so as to ensure that the entire fusion reaction process is carried out in a safe and controllable state. By placing the diagnostic plant 6 close to the main plant 1, real-time data in the reaction process can be collected more directly and quickly, providing timely and accurate monitoring information for operators to quickly respond and adjust to ensure the stability and safety of the fusion reaction. In addition, this layout structure also helps to reduce delays and errors in data transmission and improve the operating efficiency and reliability of the overall system.

[0037] Combine the following Figure 1 The detailed layout structure of each device in each area of ​​the magnetic confinement fusion power station layout structure provided by this embodiment and the mutual coordination working relationship between each area are specifically described.

In this embodiment, the protection area is set at the upper right area of ​​the control area, and the entrance and exit 62 of the protection area is aligned with the entrance and exit 61 of the control area. An isolation space is reserved between the entrance and exit 62 of the protection area and the entrance and exit 61 of the control area. In the area between the outer wall of the protection area on the side where the entrance and exit 62 of the protection area is located and the inner wall of the control area on the side where the entrance and exit 61 of the control area is located, the magnetic coil production plant 39, the auxiliary facility reserved land 40, the production service building 41 and the electrical instrument repair workshop 42 are arranged in sequence from top to bottom. The host area, the external power generation area, the power input area, the cooling and heat exchange area and the desalted water area are arranged inside the protection area. In order to facilitate the transportation of materials and equipment into the main engine area and the evacuation of low-level radioactive waste from the main engine area, the main engine area is arranged in the upper right area of ​​the protection zone, close to the magnet coil production plant 39 and the auxiliary facility reserved land. The main engine area is arranged in a rectangular shape, and the main working equipment in the main engine area is arranged in sequence along the length direction of the main engine area according to the material transportation direction. In order to facilitate the transportation of materials and equipment, the tritium factory 2 is aligned with the auxiliary facility reserved land 40, and the transfer and hoisting site 37 is arranged in the area between the auxiliary facility reserved land 40 and the tritium factory 2. The equipment cleaning plant 9 is set between the transfer and hoisting site 37 and the tritium factory 2, and the assembly hall in the tritium factory 2 is arranged close to the equipment cleaning plant 9. In the main engine area, a hot chamber 3 and a waste treatment temporary storage plant 4 are also arranged downstream of the tritium factory 2.

Therefore, outside the host area, the conversion hall 24 is aligned with the IVC power supply hall 15, and the NBI accelerating high-voltage power supply 25 is aligned with the outdoor distribution transformer 18. In order to facilitate the external energy output of the host plant 1, an external power generation area is arranged on the side close to the host plant 1 outside the host area. The external power generation area is aligned with the host plant 1 and connected through an energy transmission channel. The external power generation area circulates liquid water to the host plant 1. The energy generated in the host plant 1 heats the liquid water into steam and recirculates it back to the external power generation area. The external power generation area is provided with a steam turbine building 27, and the energy transmission channel is directly connected to the steam turbine building 27. The remaining vacant positions in the external power generation area are also provided with other auxiliary buildings such as the main transformer 28, auxiliary transformer and public distribution station 31, air compressor room 29, gas building 30, etc. The left and right sides of the external power generation area are also provided with a cooling heat exchange area and a desalted water area.

[0041] Figure 1In the figure, the blue arrows represent the input of current. The energy flow input of the magnetic confinement fusion power station involves ultra-high voltage, AC and DC. Ultra-high voltage electricity is mainly used to drive fusion reactors and other high-energy demand equipment. Ultra-high voltage is directly transmitted to the pulse power high-voltage transformer substation, which mainly involves the transmission of high-voltage electricity from the external power grid to the power station. From the pulse power high-voltage transformer substation 49, the power is further transmitted to the NBI accelerator high-voltage power supply 25 and other key facilities, ensuring the effective distribution and utilization of electric energy. The NBI accelerator high-voltage power supply 25 is a key component of the fusion reactor, using high-voltage electricity to accelerate particles to maintain the energy state of the plasma. The high-voltage platform 10 area is responsible for further distributing the high-voltage electric energy transmitted from the pulse power high-voltage transformer substation 49 to the fusion reactor area. AC power mainly serves the general electricity consumption of the plant, such as lighting, heating and cooling systems. The AC power is distributed through the transformer substation and then transmitted to various power consumption points in the plant through the secondary distribution system. The converter hall 24 is mainly responsible for converting the received AC power into DC power, or reverse operation, to meet the specific needs of different equipment in the power station for the type of electricity. The converter hall 24 is located near the power supply area to reduce the power transmission distance and improve the conversion efficiency. It is close to the main power supply line point to ensure that the power supply mode can be quickly adjusted to adapt to the dynamic changes in the operation of the power station. The reactive power compensator is used to improve the power factor of the power station, reduce energy loss, and improve power quality and transmission efficiency by compensating for reactive power. Therefore, it is arranged near the main substation to adjust the overall performance of the power system in real time. The IVC power supply hall 15 provides the necessary power supply to support the maintenance of the internal vacuum conditions of the internal vacuum container, which is crucial for the normal operation of the fusion reaction equipment. Therefore, in the plant layout structure, the IVC power supply hall 15 is close to the equipment area that requires a strict vacuum environment, that is, around the fusion reactor, to minimize the power transmission distance and improve the efficiency of power use. This layout strategy helps to ensure the power demand for daily operation of the power station, and is also convenient for maintenance and management.

[0042] Figure 1The red arrows in the middle indicate the output of energy flows, which mainly include heat flow and thermoelectric conversion flow. These output flows show how the energy generated from the fusion reactor is converted and utilized. The thermal energy is first used to generate steam, then converted into mechanical energy through the steam turbine in the turbine building 27, and finally converted into electrical energy through the generator for use outside the power plant or entering the power grid. After the thermal energy is output from the fusion reactor, it is directly transmitted to the turbine building 27, where the thermal energy is transported through an efficient insulated pipe system to minimize heat loss on the way. The steam turbine in the turbine building 27 converts this thermal energy into mechanical energy, which in turn drives the generator to generate electricity. In order to effectively manage heat emissions and maintain equipment efficiency, the circulating cooling tower 44 and the cooling water pump station 35 are strategically arranged nearby to provide the necessary cooling functions, while the water treatment plant 45 ensures that the quality of the recycled water meets environmental and technical requirements. This arrangement optimizes the efficiency of the thermoelectric conversion process and ensures maximum energy utilization.

[0043] Figure 1 The yellow arrows in the middle represent logistics, covering nuclear waste flow lines, personnel flow lines and equipment transportation flow lines. Nuclear waste is removed from the fusion reactor after use. The hot cell 3 is mainly used to treat and cool down radioactive waste. It is usually located near the nuclear reaction area to directly receive the hot waste generated by the reaction. The low-level waste plant 7 is used to treat low-level radioactive waste. These buildings are located in a relatively remote location from the main reactor to reduce the radiation impact on the main operating area of ​​the power plant. It is used to treat all types of nuclear waste and provide short-term or medium-term storage. The nuclear waste treated by the hot cell 3 and the low-level waste plant 7 is transported to the waste treatment and temporary storage plant through a dedicated safe passage. These facilities are usually located in the marginal area of ​​the power plant to reduce the impact on the main operating area. The personnel flow line design takes into account operational efficiency and safety, and directly leads from the entrance area of ​​the protected area control area to the sanitary entrance and exit 8. The equipment cleaning plant 9 and the transfer and hoisting site 37 are close to the main equipment transportation route to support the rapid processing and movement of equipment; the PF magnet coil production plant 39 is used to produce and maintain the multi-loop (PF) magnet coils required for fusion reactors, and is located on the side of the power plant or in an easily accessible area; the reserved land for auxiliary equipment is located at the edge of the power plant to facilitate future expansion. These layout structures take into account operational efficiency, safety protection, and environmental protection to ensure that the power plant can operate efficiently and safely.

[0044] Figure 1The green arrows in the middle represent signal flows, including measurement flows and control flows. These flow lines are key to ensuring accurate data collection and real-time control of power plant data, which is crucial to power plant safety and efficiency. The internal diagnostic plant 6 of the nuclear island is responsible for monitoring various physical parameters during the nuclear reaction process, such as temperature, pressure, and radiation levels, to ensure that the reaction process is carried out under safe control. This plant is usually located close to the main engine plant 1 to facilitate direct data collection during the reaction process. The electrical and instrumentation repair workshop 42 is responsible for the maintenance and repair of all electrical and instrumentation equipment to ensure the stable operation of the power plant's electrical system. It is close to the diagnostic plant 6 and the main transportation channel, which facilitates a quick response to any electrical equipment problems that require maintenance or adjustment.
