Description

Technical Field

[0001] This invention relates to the field of nuclear power technology, and more specifically to a nuclear reactor building structure. Background Technology

[0002] In the field of nuclear power generation, the safety and stability of nuclear reactor buildings are of paramount importance. Nuclear reactors generate a large amount of heat during operation, requiring effective heat dissipation and cooling to prevent overheating that could lead to equipment damage or safety accidents.

[0003] Existing active cooling systems rely on external power sources and mechanical equipment to drive the circulation of cooling media, such as circulating water systems and forced ventilation. Under normal circumstances, they can efficiently control the temperature within the plant. However, their cooling capacity is greatly reduced during power outages or equipment malfunctions, thereby increasing nuclear safety risks. Summary of the Invention

[0004] In view of this, the present invention provides a nuclear reactor building structure to solve the problem that the cooling capacity of existing building structures, which rely on electrical energy and mechanical equipment for heat dissipation, is greatly reduced when power is interrupted or equipment failure occurs.

[0005] Specifically, the nuclear reactor building structure of the present invention includes a reactor building outer shell, a natural air intake structure, and a reactor building inner shell; the natural air intake structure is installed at the reactor building outer shell, and the natural air intake structure has a windward natural air intake corridor and a natural air intake port that connects the interior of the reactor building outer shell with the natural air intake corridor, so as to guide natural airflow into the interior of the reactor building outer shell; the reactor building inner shell is installed inside the reactor building outer shell.

[0006] Beneficial effects: The design of the natural air intake corridor and inlets in the natural air intake structure guides natural airflow from the external environment into the interior of the reactor building. This allows for efficient utilization of natural air without relying on energy sources, reducing reliance on ventilation equipment. Even in emergencies such as power outages, ventilation can still be provided to the interior and exterior of the reactor building, enhancing its reliability. Furthermore, it eliminates the need for regular inspections and maintenance of ventilation equipment, thus reducing maintenance costs. In addition, natural ventilation helps reduce energy consumption and greenhouse gas emissions.

[0007] In one alternative embodiment, the natural air intake corridor is a stable air intake corridor; wherein, in the direction extending from the external environment toward the interior of the reactor building shell, the air supply cross-sectional area of ​​the air supply channel inside the natural air intake corridor for natural air flow gradually decreases.

[0008] Beneficial effects: By designing the natural air intake corridor with a gradually decreasing air supply cross-sectional area, it helps stabilize wind speed and reduces the direct impact of external environmental changes such as sudden wind direction changes and wind speed fluctuations on the ventilation effect inside the reactor building's outer shell. This guides natural wind into the outer building body in a uniform and orderly manner, reducing airflow turbulence and dead zones, thereby improving ventilation efficiency. Furthermore, compared to traditional mechanical ventilation systems, this natural ventilation method eliminates the need for complex control systems and power equipment, thus reducing system complexity and maintenance costs.

[0009] In one alternative embodiment, the nuclear reactor building structure further includes a sealing plate installed between the outer wall of the inner shell of the reactor building and the inner wall of the outer shell of the reactor building, and the sealing plate is located near the top wall of the air inlet of the outer shell of the reactor building that allows natural air to enter its interior, in order to separate the space below the sealing plate and the space above the sealing plate of the outer shell of the reactor building.

[0010] Beneficial effects: By setting up the sealing plate, the interior of the reactor building is divided into two separate spaces, upper and lower, reducing the impact of the external environment on natural wind. This allows natural wind to enter the required area smoothly, reducing the degree of turbulence inside the reactor building and reducing energy loss caused by airflow turbulence. This optimizes the flow path of natural wind and helps improve ventilation efficiency.

[0011] In one optional embodiment, the sealing plate is provided with a first drain outlet, and the height of the end of the sealing plate away from the first drain outlet is higher than the height of the end of the sealing plate close to the first drain outlet; the nuclear reactor building structure also includes a water inlet pipe, the inlet of which is connected to the first drain outlet, and the outlet of which is located in the drainage area outside the reactor building shell.

[0012] Beneficial effects: By incorporating a first drain outlet on the sealing plate and ensuring that the end of the sealing plate furthest from the first drain outlet is higher than the end closest to it, accumulated water can be effectively drained. This prevents water from stagnating at the sealing plate and avoids potential damage such as corrosion or leakage to the sealing plate, reactor building outer shell, and reactor building inner shell, thereby extending their service life. Simultaneously, timely drainage ensures the interior of the reactor building remains dry and clean, providing a safe working environment for personnel and preventing slips or falls due to water accumulation.

[0013] In one optional embodiment, the nuclear reactor building structure further includes a flow distribution plate installed between the outer wall of the inner shell of the reactor building and the inner wall of the outer shell of the reactor building, and the flow distribution plate is located above the air inlet of the outer shell of the reactor building for natural air to enter its interior. The flow distribution plate has multiple ventilation holes, and among the multiple ventilation holes, the diameter of the ventilation hole closer to the natural air inlet is smaller than the diameter of the ventilation hole farther away from the natural air inlet.

[0014] Beneficial effects: By installing a flow distribution plate and placing it above the air inlet on the reactor building's outer shell that allows natural air to enter, the natural air entering the reactor building's outer shell is distributed as it rises. Since the multiple ventilation holes on the flow distribution plate are designed such that the diameter of the holes closer to the natural air inlet is smaller than that of the holes farther away, the flow rate through each ventilation hole can be kept consistent. This ensures that the natural air is evenly distributed on the outer wall of the reactor building's inner shell, thereby achieving uniform heat exchange, avoiding localized overheating, reducing reliance on equipment, and helping to reduce the operating costs and carbon emissions of nuclear power plants.

[0015] In one optional embodiment, the nuclear reactor building structure further includes an exhaust structure, which is disposed on the top of the reactor building shell and has a natural air outlet that connects the interior of the reactor building shell with the external environment and a natural air corridor for guiding the natural airflow after heat exchange to the outside.

[0016] Beneficial effects: After heat exchange, the temperature of natural wind increases and its density decreases, causing it to gradually rise. By adding an exhaust structure to the top of the reactor building's outer shell that connects to both the interior of the reactor building and the external environment, natural wind can flow towards the outside environment when it reaches the exhaust structure. In other words, by utilizing the heating characteristics of natural wind in the exhaust structure, the dependence of natural wind flow on equipment is reduced, which helps lower the operating costs and carbon emissions of the nuclear power plant. Simultaneously, the natural wind flow provides natural ventilation to the interior of the reactor building's outer shell, helping to optimize the internal environmental conditions, improve air quality, reduce odors and humidity, and provide a comfortable and healthy working environment for staff.

[0017] In one alternative embodiment, the nuclear reactor building structure further includes a water inlet plate, which is installed on the inner wall of the reactor building shell. The water inlet plate guides the liquid water generated during the natural wind heat exchange process to the external drainage area of ​​the reactor building shell through water inlet pipes.

[0018] Beneficial effects: By installing water guide plates on the inner wall of the reactor building's outer shell, liquid water generated after natural air passes through the heat exchanger is guided to the external drainage area. Since the water guide plates are connected to water pipes, the generated liquid water can enter the pipes and flow to the external drainage area, achieving efficient drainage and preventing liquid water accumulation inside the reactor building's outer shell. This reduces safety hazards such as dampness, corrosion, or slipperiness caused by water accumulation. Furthermore, centralized discharge of the generated liquid water simplifies maintenance and cleaning. In addition, timely external discharge of liquid water generated during heat exchange prevents it from flowing into the natural air intakes, thus avoiding obstruction of airflow.

[0019] In one optional embodiment, the water guide plate has a gradually decreasing height in the direction extending from the inner wall of the reactor building shell toward the inner shell of the reactor building, so that the water guide plate is inclined downward; wherein, the end of the water guide plate away from the inner wall of the reactor building shell is horizontally disposed between the inner wall of the reactor building shell and the first drain outlet.

[0020] Beneficial effects: By arranging the water guide plate in a form where its height gradually decreases from the inner wall of the reactor building towards the inner shell, liquid water can flow naturally along the water guide plate under its own gravity. Furthermore, by positioning the end of the water guide plate furthest from the inner wall of the reactor building horizontally between the inner wall of the reactor building and the first drain outlet, condensate, after leaving the water guide plate, flows under gravity to the sealing plate. Due to the structure of the sealing plate itself, it then flows smoothly to the first drain outlet for discharge. This achieves effective liquid water diversion without the need for additional power or equipment, simplifying drainage and reducing energy consumption. Simultaneously, the downward-sloping shape of the water guide plate prevents water accumulation, reducing corrosion and mold problems caused by water accumulation, and helping to maintain a clean and hygienic internal environment of the reactor building.

[0021] In one optional embodiment, the water intake plate is arranged in a ring; and the height of the water intake plate, in the direction extending from the inner wall of the reactor building shell towards the inner shell of the reactor building, exhibits a trend of first decreasing and then increasing, or a trend of gradually increasing height, so that the water intake plate and the inner wall of the reactor building shell form an annular water collection chamber; a second drain outlet is provided at the lowest point of the water intake plate, and the second drain outlet guides the liquid water generated during the natural wind heat exchange process to the external drainage area of ​​the reactor building shell through a water intake pipe.

[0022] Beneficial effects: By arranging the water guide plate in a form where its height initially decreases and then increases or gradually increases in the direction extending from the inner wall of the reactor building's outer shell towards the inner shell, the liquid water generated during heat exchange can be guided. Furthermore, by forming an annular water collection chamber with the inner wall of the reactor building's outer shell, the liquid water generated during heat exchange can be collected efficiently. Since a second drain outlet is located at the lowest point of the water guide plate and is connected to the water inlet pipe, the liquid water accumulated in the annular water collection chamber can be smoothly discharged, improving drainage efficiency. In addition, due to the water guide plate's design, natural wind flowing to the water guide plate will not affect the water collection inside the annular water collection chamber, reducing interference between accumulated water and natural wind.

[0023] In one alternative embodiment, the nuclear reactor building structure further includes a base plate installed at the bottom of the reactor building's outer shell.

[0024] Beneficial effect: It supports the reactor building by installing the base plate at the bottom of the reactor building shell. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In the field of nuclear power generation, the safety and stability of nuclear reactor buildings are of paramount importance. Nuclear reactors generate a large amount of heat during operation, requiring effective heat dissipation and cooling to prevent overheating that could lead to equipment damage or safety accidents.

[0046] Traditional ventilation and cooling systems often rely on external electrical and mechanical equipment to drive the circulation of cooling media, such as circulating water systems and forced ventilation. Under normal circumstances, these systems can efficiently control the temperature within the plant. However, their cooling capacity is significantly reduced during power outages or equipment malfunctions, thereby increasing nuclear safety risks.

[0047] Therefore, this application utilizes natural wind, without the need for external power or mechanical equipment, and uses the natural convection principle generated by the temperature difference between hot and cold air to form a continuous airflow path from the natural air inlet to the natural air outlet, achieving continuous ventilation and cooling without any mechanical driving force, thus enhancing the stability and reliability of the system in emergencies such as power outages.

[0048] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0049] According to an embodiment of the present invention, a nuclear reactor building structure is provided, such as... Figure 1 and Figure 2 As shown, the nuclear reactor building structure includes a reactor building outer shell 1, a natural air intake structure 2, and a reactor building inner shell 3.

[0050] The natural air intake structure 2 is installed at the outer shell of the reactor building 1. The natural air intake structure 2 is provided with a natural air intake corridor 21 facing the wind and a natural air intake 22 that connects the interior of the outer shell of the reactor building 1 with the natural air intake corridor 21, so as to guide the natural air to flow into the interior of the outer shell of the reactor building 1. The inner shell of the reactor building 3 is installed inside the outer shell of the reactor building 1.

[0051] With this configuration, the design of the natural air intake corridor 21 and the natural air intake 22 in the natural air intake structure can guide the natural airflow from the external environment to the interior of the reactor building shell 1. This allows for efficient utilization of natural air without relying on energy sources and reduces dependence on ventilation equipment. In the event of an emergency such as a power outage, it can still provide ventilation to the interior of the reactor building, thus enhancing the reliability of the reactor building.

[0052] At the same time, it eliminates the need for regular inspections and maintenance of ventilation equipment, thereby reducing maintenance costs. In addition, natural ventilation helps reduce energy consumption and greenhouse gas emissions.

[0053] It can be explained that there are multiple natural air intake structures 2, and these multiple natural air intake structures 2 are spaced apart on the outer wall of the reactor building shell 1.

[0054] Preferably, multiple natural air intake structures 2 are arranged in an array around the circumferential direction and / or axial direction of the reactor building shell 1.

[0055] In one embodiment, such as Figure 1 and Figure 2 As shown, the natural air intake corridor 21 is a stable air corridor; wherein, in the direction extending from the external environment toward the interior of the reactor building shell 1, the air supply cross-sectional area of ​​the air supply channel inside the natural air intake corridor 21 for natural air flow gradually decreases.

[0056] This configuration, by setting the natural air intake corridor 21 to have a gradually decreasing air supply cross-sectional area, helps to stabilize the wind speed, reduce the direct impact of external environmental changes such as sudden changes in wind direction and wind speed fluctuations on the ventilation effect inside the reactor building shell 1, guides natural wind to enter the interior of the external building body in a uniform and orderly manner, reduces airflow turbulence and dead zones, thereby improving the ventilation effect.

[0057] At the same time, compared with traditional mechanical ventilation systems, this natural ventilation method does not require complex control systems and power equipment, thereby reducing system complexity and maintenance costs.

[0058] It can be noted that the inner shell 3 of the reactor building is a device used for nuclear reactions.

[0059] It can be noted that, from a top-down perspective, the natural air intake corridor 21 presents an overall conical structure, which facilitates the gathering of more natural wind for the reactor building shell 1.

[0060] It can be explained that the openings of the natural air intake structure face the prevailing wind direction, such as... Figure 1 As shown in the middle K direction, it is designed to facilitate the collection of natural wind.

[0061] It can be explained that by setting the natural air inlet 22 at a certain height, the friction generated by the ground during the natural airflow is reduced, and the phenomenon that the natural wind speed is slowed down due to the ground friction is improved, thereby utilizing higher wind speed and thus improving ventilation efficiency.

[0062] It can be noted that the natural air intake corridor is equipped with a filtration device, such as a filter screen, to remove dust, pollutants and other particles that enter the reactor building's outer shell 1, thereby improving air quality.

[0063] It can be noted that in this embodiment, the horizontal cross-section of the inner wall of the reactor building shell 1 and the horizontal cross-section of the outer wall of the reactor building inner shell 3 are both circular. At this time, the inner wall of the reactor building shell 1 and the outer wall of the reactor building inner shell 3 enclose a sleeve-shaped cavity.

[0064] In one embodiment, such as Figure 1 and Figure 2 As shown, the nuclear reactor building structure also includes a sealing plate 4, which is installed between the outer wall of the inner shell 3 of the reactor building and the inner wall of the outer shell 1 of the reactor building. The sealing plate 4 is located near the top wall of the air inlet of the outer shell 1 of the reactor building, which allows natural air to enter its interior, in order to separate the space below the sealing plate 4 and the space above the sealing plate 4 of the outer shell 1 of the reactor building.

[0065] This configuration, through the sealing plate 4, divides the interior of the reactor building shell 1 into two separate spaces, upper and lower, reducing the impact of the external environment on natural wind. This allows natural wind to smoothly enter the required area, reducing the degree of turbulence it remains inside the reactor building shell 1, reducing energy loss caused by airflow turbulence, optimizing the flow path of natural wind, and helping to improve ventilation efficiency.

[0066] Preferably, the sealing plate 4 is set at a height range of 2m to 4m.

[0067] Preferably, the sealing plate 4 is made of a lead composite material or boronized polyethylene, etc.

[0068] In one embodiment, such as Figures 1 to 3 As shown, the sealing plate 4 is provided with a first drain outlet 41, and the height of the end of the sealing plate 4 away from the first drain outlet 41 is higher than the height of the end of the sealing plate 4 near the first drain outlet 41; the nuclear reactor building structure also includes a water inlet pipe, the inlet of which is connected to the first drain outlet 41, and the outlet of which is located in the external drainage area of ​​the reactor building shell 1.

[0069] This configuration, by providing a first drain outlet 41 on the sealing plate 4 and ensuring that the height of the end of the sealing plate 4 furthest from the first drain outlet 41 is higher than the height of the end of the sealing plate 4 closest to the first drain outlet 41, can effectively guide the accumulated water to the first drain outlet 41 for discharge, preventing water from stagnating at the sealing plate 4 and preventing potential damage such as corrosion and leakage to the sealing plate 4, the reactor building outer shell 1, and the reactor building inner shell 3, thereby extending the service life of the sealing plate 4, the reactor building outer shell 1, and the reactor building inner shell 3.

[0070] At the same time, by draining the accumulated water in a timely manner, the interior of the reactor building 1 is kept dry and clean, providing a safe working environment for the staff and preventing them from slipping or falling due to water accumulation.

[0071] In one embodiment, such as Figure 1 and Figure 2 As shown, the nuclear reactor building structure also includes a flow distribution plate 5. The flow distribution plate 5 is installed between the outer wall of the inner shell 3 of the reactor building and the inner wall of the outer shell 1 of the reactor building. The flow distribution plate 5 is located above the air inlet of the outer shell 1 of the reactor building, which allows natural air to enter its interior. The flow distribution plate 5 has multiple ventilation holes. Among the multiple ventilation holes, the diameter of the ventilation hole closer to the natural air inlet 22 is smaller than the diameter of the ventilation hole farther away from the natural air inlet 22.

[0072] This configuration, with the flow distribution plate 5 positioned above the air inlet of the reactor building shell 1 that allows natural air to enter, distributes the flow of natural air as it rises. Since the multiple ventilation holes on the flow distribution plate 5 are designed such that the diameter of the holes closer to the natural air inlet 22 is smaller than that of the holes farther from the natural air inlet 22, consistent flow through each ventilation hole is achieved. This ensures uniform distribution of natural air on the outer wall of the reactor building shell 3, resulting in uniform heat exchange, preventing localized overheating, reducing reliance on equipment, and helping to lower the operating costs and carbon emissions of the nuclear power plant.

[0073] Preferably, the flow distribution plate 5 is set at a height range of 4m to 6m.

[0074] Preferably, the flow distribution plate 5 is made of lead composite material or boronized polyethylene material.

[0075] It can be explained that the sealing plate 4 and the flow distribution plate 5 support the inner wall of the reactor building shell 1 and the outer wall of the reactor building inner shell 3, acting as ring-shaped reinforcing ribs and ribs, improving the overall stability and durability, and making the entire building structure more stable.

[0076] In one embodiment, such as Figure 1 and Figure 2 As shown, the nuclear reactor building structure also includes an exhaust structure 6, which is located on the top of the reactor building shell 1. The exhaust structure 6 has a natural air outlet 61 that connects the interior of the reactor building shell 1 with the external environment, and a natural air outlet corridor 62 that guides the natural airflow after heat exchange to the outside.

[0077] With this configuration, the temperature of the natural wind increases and its density decreases after heat exchange, causing it to gradually rise. By adding an air outlet structure 6 at the top of the reactor building shell 1 that connects to the interior of the reactor building shell 1 and to the external environment, the natural wind can flow to the external environment when it reaches the air outlet structure 6. That is, by utilizing the heating characteristics of natural wind to arrange the air outlet structure 6, the dependence of natural wind flow on equipment is reduced, which helps to reduce the operating costs and carbon emissions of the nuclear power plant.

[0078] At the same time, the natural wind can achieve natural ventilation and air exchange inside the reactor building shell 1 during the flow process, which helps to optimize the internal environmental conditions of the reactor building shell 1, improve air quality, reduce odor and dampness, and provide a comfortable and healthy working environment for staff.

[0079] In one embodiment, such as Figures 1 to 3 As shown, the nuclear reactor building structure also includes a water inlet plate 7, which is installed on the inner wall of the reactor building shell 1. The water inlet plate 7 guides the liquid water generated during the natural wind heat exchange process to the external drainage area of ​​the reactor building shell 1 through the water inlet pipe.

[0080] This configuration, by installing a water guide plate 7 on the inner wall of the reactor building shell 1, provides guidance for the liquid water generated after the natural wind undergoes heat exchange. Since the water guide plate 7 is connected to the water guide pipe, the generated liquid water can enter the water guide pipe and flow to the external drainage area through the water guide pipe, achieving efficient drainage and preventing the accumulation of liquid water inside the reactor building shell 1, thereby reducing safety hazards such as dampness, corrosion, or slipping caused by water accumulation.

[0081] Meanwhile, centralized discharge of the generated liquid water makes maintenance and cleaning more convenient.

[0082] It can be explained that there are multiple water inlet plates 7, and the multiple water inlet plates 7 are spaced apart on the inner wall of the reactor building shell 1.

[0083] Preferably, multiple water-guiding plates 7 are arranged in an array around the circumferential direction and / or axial direction of the reactor building shell 1.

[0084] Preferably, multiple water inlet plates 7 are arranged between the flow distribution plate 5 and the sealing plate 4 along the axial direction of the reactor building shell 1.

[0085] In other alternative embodiments, at least one of the plurality of water inlet plates 7 is disposed along the axial direction of the reactor building shell 1 on the side of the flow distribution plate 5 away from the sealing plate 4.

[0086] In one embodiment, such as Figures 1 to 3 As shown, the height of the water inlet plate 7 gradually decreases in the direction extending from the inner wall of the reactor building shell 1 toward the inner shell 3 of the reactor building, so that the water inlet plate 7 is inclined downward; wherein, the end of the water inlet plate 7 away from the inner wall of the reactor building shell 1 is horizontally arranged between the inner wall of the reactor building shell 1 and the first drain outlet 41.

[0087] This configuration, by setting the water guide plate 7 in a form where its height gradually decreases in the direction extending from the inner wall of the reactor building shell 1 towards the inner shell 3 of the reactor building, allows liquid water to flow naturally along the water guide plate 7 under the influence of gravity. Furthermore, by positioning the end of the water guide plate 7 furthest from the inner wall of the reactor building shell 1 horizontally between the inner wall of the reactor building shell 1 and the first drain outlet 41, condensate, after leaving the water guide plate 7, will flow under gravity to the sealing plate 4. Due to the structure of the sealing plate 4 itself, it will then flow to the first drain outlet 41 for smooth discharge. This achieves effective liquid water diversion without the need for additional power or equipment, simplifying the drainage process and reducing energy consumption.

[0088] Meanwhile, since the water inlet plate 7 is tilted downwards, it avoids water accumulation and reduces problems such as corrosion and mold caused by water accumulation, which helps to keep the internal environment of the reactor building shell 1 clean and hygienic.

[0089] In one embodiment, such as Figures 1 to 3 As shown, the water inlet plate 7 is arranged in a ring; and the height of the water inlet plate 7 in the direction extending from the inner wall of the reactor building outer shell 1 towards the inner shell 3 of the reactor building is as follows. Figure 4 The trend shown is a decline followed by an increase, or as... Figure 5 The height shown is gradually increasing so that the water inlet plate 7 and the inner wall of the reactor building shell 1 form an annular water collection chamber; the lowest point of the water inlet plate 7 is provided with a second drain outlet 71, which guides the liquid water generated during the natural wind heat exchange process to the external drainage area of ​​the reactor building shell 1 through the water inlet pipe.

[0090] This configuration, where the water inlet plate 7 is arranged such that its height initially decreases and then increases or gradually increases in the direction extending from the inner wall of the reactor building outer shell 1 towards the inner shell 3, guides the liquid water generated during heat exchange. Furthermore, by forming an annular water collection chamber with the inner wall of the reactor building outer shell 1, the liquid water generated during heat exchange can be collected efficiently. Since a second drain outlet 71 is located at the lowest point of the water inlet plate 7 and is connected to the water inlet pipe, the liquid water accumulated in the annular water collection chamber can be smoothly discharged, improving drainage efficiency. In addition, due to the arrangement of the water inlet plate 7, natural wind flowing to the water inlet plate 7 will not affect the water collection inside the annular water collection chamber, reducing interference between the accumulated water and natural wind.

[0091] In one embodiment, such as Figure 1 and Figure 2 As shown, the nuclear reactor building structure also includes a base plate 8, which is installed at the bottom of the reactor building shell 1.

[0092] This configuration allows for support of the reactor building's outer shell 1 by mounting the base plate 8 at its base.

[0093] It should be noted that the base plate 8 is made of reinforced concrete. It provides a robust supporting foundation for the nuclear reactor building structure, ensuring the stability and safety of the nuclear reaction process.

[0094] The nuclear reactor building structure used in the above embodiments introduces a large amount of natural air (cold air) into the reactor building's outer shell 1 through the natural air intake structure 2. This natural air enters the reactor building's outer shell 1 through the natural air intake corridor 21 and the natural air intake 22, and is then evenly distributed by the flow distribution plate 5, ensuring uniform heat exchange between the natural air and the reactor building's inner shell 3. When the natural air comes into contact with the reactor building's inner shell 3, which is heated by the nuclear reaction, its temperature rises, forming hot air. Its density decreases, and it gradually rises until it reaches the natural air outlet corridor 62 and is discharged through the natural air outlet 61. This forms a continuous flow path, achieving continuous cooling of the reactor building's inner shell 3.

[0095] The natural wind flows in the following direction inside the reactor building's outer shell 1: Figure 2 The direction of the arrow in the middle L direction.

[0096] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
