Description

Technical Field

[0001] This invention relates to the field of nuclear engineering technology, and in particular to a mobile self-balancing reactor. Background Technology

[0002] Mobile self-balancing reactors generate decay heat after operation, and it is necessary to ensure that the decay heat is removed even when they are in motion. Therefore, passive heat removal devices are usually installed to remove the decay heat from the reactor.

[0003] Currently, heat removal devices for mobile self-balancing reactors do not take into account potential traffic accidents during transportation. If a vehicle overturns, the original heat removal device may lose its heat removal function, leading to fuel overheating, melting, and radioactive release in the reactor due to the inability to remove heat in time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art by providing a mobile self-balancing reactor that can automatically switch to a stable state after the mobile self-balancing reactor overturns, thus maintaining the normal heat removal function of the mobile self-balancing reactor.

[0005] This invention provides a mobile self-balancing reactor, comprising a reactor body and a heat extraction shell. The reactor body is a horizontal reactor; the heat extraction shell surrounds the reactor body and is fixedly connected to it; the outer surface of the heat extraction shell is smooth, allowing it to roll freely along with the reactor body; the heat extraction shell has an exhaust end and a grounding end opposite to each other, and the center of gravity of both the reactor body and the heat extraction shell is biased towards the grounding end of the heat extraction shell, so that after rolling, the heat extraction shell and the reactor body transition to a stable state under the action of gravity; in the stable state, the reactor body is horizontal, and the exhaust end is located above the grounding end. A first gas flow channel is provided between the heat extraction shell and the reactor body, the first gas flow channel having a first inlet and a first exhaust port; the first inlet is located at the grounding end of the heat extraction shell, and the first exhaust port is located at the exhaust end of the heat extraction shell.

[0006] In some embodiments, the reactor body includes a pressure vessel and a reactor core and in-core components. A heat exhaust shell surrounds the outside of the reactor body and is fixedly connected to the pressure vessel; a gap exists between the heat exhaust shell and the pressure vessel, forming the first gas flow channel. The reactor core and in-core components are disposed inside the pressure vessel. The centers of gravity of both the pressure vessel and the reactor core and in-core components are offset towards the grounding end of the heat exhaust shell.

[0007] In some embodiments, the center of gravity of the heat-exporting housing coincides with its geometric center.

[0008] In some embodiments, the heat-exporting shell has an annular cross-sectional shape; the material of the heat-exporting shell is a homogeneous material.

[0009] In some embodiments, the center of gravity of the heat-exporting housing is biased toward the grounding terminal of the heat-exporting housing.

[0010] In some embodiments, the heat-exporting housing has an annular cross-sectional shape. The average density of the material at the grounding end of the heat-exporting housing is greater than the average density of the material at the exhaust end of the heat-exporting housing.

[0011] In some embodiments, the heat-exporting outer shell has a cross-sectional shape that is smaller at the top and larger at the bottom. The material of the heat-exporting outer shell is a homogeneous material, or the average density of the material in the lower part of the heat-exporting outer shell is greater than the average density of the material in the upper part of the heat-exporting outer shell.

[0012] In some embodiments, a second gas flow channel is formed inside the heat-exporting housing, the second gas flow channel having a second air inlet and a second air outlet; the second air outlet is connected to the first air inlet and isolated from the outside air, so that all the gas entering the first gas flow channel flows into the second gas flow channel; the second air inlet is located at the exhaust end of the heat-exporting housing.

[0013] In some embodiments, after the heat exhaust shell and the reactor body are converted to a stable state, the second air inlet and the first exhaust outlet are both oriented in a downward direction.

[0014] In some embodiments, there are multiple first gas flow channels and multiple second gas flow channels. The first inlets of the multiple first gas flow channels and the second exhaust ports of the multiple second gas flow channels are all interconnected.

[0015] Therefore, the mobile self-balancing reactor provided in this embodiment of the invention, by setting a heat export shell, surrounds the reactor body and is fixedly connected to it, which protects the reactor body and enables the reactor body to move synchronously. By setting the outer surface of the heat export shell as a smooth, convex surface, the heat export shell can roll freely with the reactor body when the mobile self-balancing reactor overturns in a traffic accident. Furthermore, by setting opposing exhaust and grounding ends on the heat export shell, the center of gravity of both the reactor body and the heat export shell is biased towards the grounding end of the heat export shell. This allows the heat export shell to automatically transition to a stable state under gravity after rolling freely with the reactor body, keeping the reactor body in a horizontal position to maintain normal operation, and positioning the exhaust end above the grounding end. By setting a first gas flow channel between the heat export shell and the reactor body, with the first inlet of the first gas flow channel located at the grounding end of the heat export shell and the first exhaust port located at the exhaust end of the heat export shell, after the heat export shell drives the reactor body to a stable state, the first exhaust port is located above the first inlet. This allows external gas to enter the first gas flow channel through the first inlet to dissipate heat from the reactor body. The gas, after being heated by heat dissipation, is then discharged from the first exhaust port at the top of the heat export shell under the action of the pressure difference. This ensures that external gas can continuously dissipate heat from the reactor body, maintaining the normal heat export function of the mobile self-balancing reactor and preventing the reactor body from overheating, melting, and releasing radioactivity due to the inability to export heat in time.

[0024] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0025] Example 1: like Figure 1 and Figure 2As shown, this embodiment of the invention provides a mobile self-balancing reactor, which includes a reactor body and a heat extraction shell 3. The reactor body is a horizontal reactor, and the heat extraction shell 3 surrounds the outside of the reactor body and is fixedly connected to it. The outer surface of the heat extraction shell 3 is a convex, smooth surface, so that the heat extraction shell 3 can drive the reactor body to roll freely. Figure 3 As shown, the heat extraction casing 3 has an exhaust end 31 and a grounding end 33 arranged opposite to each other. The center of gravity of both the reactor body and the heat extraction casing 3 is biased towards the grounding end 33 of the heat extraction casing 3, so that the heat extraction casing 3 and the reactor body can transition to a stable state under the action of gravity after rolling. In the stable state, the reactor body is horizontal, and the exhaust end 31 is located above the grounding end 33. A first gas flow channel 6 is provided between the heat extraction casing 3 and the reactor body. The first gas flow channel 6 has a first air inlet 4 and a first exhaust outlet 5. The first air inlet 4 is located at the grounding end 33 of the heat extraction casing 3, and the first exhaust outlet 5 is located at the exhaust end 31 of the heat extraction casing 3.

[0026] For example, a mobile self-balancing reactor can be transported by vehicle. The type of mobile self-balancing reactor can be a horizontal reactor.

[0027] For example, the heat venting shell 3 can cover the outside of the reactor body. The heat venting shell 3 is fixed to the outside of the reactor body by welding or fasteners (bolts, etc.) to maintain the stability of the relative position of the heat venting shell 3 and the reactor body. In the event of a traffic accident involving the vehicle transporting the mobile self-balancing reactor, causing the mobile self-balancing reactor to fall to the ground and overturn, the heat venting shell 3 can protect the reactor body from the outside.

[0028] By making the outer surface of the heat-exporting housing 3 a smooth, convex surface, it is understandable that the heat-exporting housing 3 can roll freely and eventually remain stable under the influence of gravity.

[0029] For example, such as Figure 1 and Figure 2 As shown, the reactor body can be cylindrical, and the heat extraction shell 3 is also cylindrical, with both ends of the heat extraction shell 3 being hemispherical or ellipsoidal, so that the entire outer surface of the heat extraction shell 3 is a smooth surface, avoiding any defects. Figure 4 The heat export casing 3 shown is positioned vertically on the ground so that it can move freely along with the reactor body.

[0030] It should be noted that the center of gravity of both the reactor body and the heat exhaust shell 3 refers to the center of gravity of the combined assembly consisting of the reactor body and the heat exhaust shell 3.

[0031] By shifting the center of gravity of both the reactor body and the heat exhaust shell 3 towards the grounding end 33 of the heat exhaust shell 3, it can be understood that when the mobile self-balancing reactor falls to the ground and overturns, the heat exhaust shell 3 can cause the reactor body to roll freely together and automatically transition to a stable state under the action of gravity. In this stable state, the reactor body is horizontal to ensure the normal operation of the reactor body, and the grounding end 33 is at the bottom of the heat exhaust shell 3 (for example, the grounding end 33 is in direct contact with the ground), while the exhaust end 31 is at the top of the heat exhaust shell 3.

[0032] For example, the number of first air inlets 4 can be one or more, and the number of first gas channels 6 can be one or more. When multiple first gas channels 6 are used in the design, the multiple first gas channels 6 are distributed in parallel in sequence along the longitudinal direction (the centerline direction of the horizontal reactor), and adjacent first gas channels 6 are separated by guide plates.

[0033] like Figure 3 As shown, Figure 3 The arrows in the diagram indicate the airflow direction. Because the first air inlet 4 of the first gas flow channel 6 is located at the grounding end 33 of the heat extraction shell 3, and the first exhaust port 5 is located at the exhaust end 31 of the heat extraction shell 3, after the heat extraction shell 3 drives the reactor body to a stable state, the first exhaust port 5 of the first gas flow channel 6 can be positioned above the first air inlet 4. This allows external gas (air) to enter the first gas flow channel 6 through the first air inlet 4 to dissipate heat from the reactor body, and the gas that has been heated by heat dissipation from the reactor body is discharged from the first exhaust port 5 under the action of the pressure difference. This allows external gas to continuously dissipate heat from the reactor body, maintaining the normal heat extraction function of the mobile self-balancing reactor and preventing the reactor body from overheating, melting, and releasing radioactivity due to the inability to remove heat in time.

[0034] Therefore, the mobile self-balancing reactor provided in this embodiment of the invention, by setting a heat-exiting shell 3, surrounds the reactor body and is fixedly connected to it, allowing the heat-exiting shell 3 to protect the reactor body and drive it to move synchronously. By setting the outer surface of the heat-exiting shell 3 as a convex smooth surface, the heat-exiting shell 3 can drive the reactor body to roll freely when the mobile self-balancing reactor overturns in a traffic accident. Furthermore, by setting opposing exhaust ends 31 and grounding ends 33 on the heat-exiting shell 3, the center of gravity of both the reactor body and the heat-exiting shell 3 is biased towards the grounding end 33 of the heat-exiting shell 3. This allows the heat-exiting shell 3 to automatically transition to a stable state under the action of gravity after driving the reactor body to roll freely, with the exhaust end 31 located above the grounding end 33. By setting a first gas flow channel 6 between the heat export shell 3 and the reactor body, with the first air inlet 4 of the first gas flow channel 6 located at the grounding end 33 of the heat export shell 3 and the first exhaust port 5 located at the exhaust end 31 of the heat export shell 3, the heat export shell 3 can drive the reactor body to a stable state, making the reactor body horizontal to maintain the normal working state of the reactor body. The first exhaust port 5 is located above the first air inlet 4, allowing external gas to enter the first gas flow channel 6 through the first air inlet 4 to dissipate heat from the reactor body. The gas that has been heated by heat dissipation from the reactor body is discharged from the first exhaust port 5 at the top of the heat export shell 3 under the action of the pressure difference. This allows external gas to continuously dissipate heat from the reactor body, maintaining the normal heat export function of the mobile self-balancing reactor and preventing the reactor body from overheating, melting, and releasing radioactivity due to the inability to export heat in time.

[0035] In some embodiments, such as Figure 3 As shown, the reactor body includes a pressure vessel 2 and a reactor core and in-core components 1. A heat extraction shell 3 surrounds the outside of the reactor body and is fixedly connected to the pressure vessel 2; a gap exists between the heat extraction shell 3 and the pressure vessel 2, forming a first gas flow channel 6. The reactor core and in-core components 1 are disposed inside the pressure vessel 2. The centers of gravity of both the pressure vessel 2 and the reactor core and in-core components 1 are biased towards the grounding end 33 of the heat extraction shell 3.

[0036] For example, such as Figure 3As shown, in the cross-section of the reactor body, the pressure vessel 2 is circular, and the material of the pressure vessel 2 is homogeneous. Therefore, the center of gravity of the pressure vessel 2 is located at its geometric center (the center of the circle). If the material of the reactor core and in-core components 1 is homogeneous, the center of gravity of the reactor core and in-core components 1 is located at its geometric center. In this case, the geometric center of the reactor core and in-core components 1 can be set closer to the grounding end 33 of the heat exhaust shell 3 than the geometric center of the pressure vessel 2. This way, the centers of gravity of both the pressure vessel 2 and the reactor core and in-core components 1 will be biased towards the grounding end 33 of the heat exhaust shell 3.

[0037] With the above settings, the overall center of gravity of the reactor body can be shifted towards the grounding end 33 of the heat outlet shell 3, which means that the center of gravity of both the reactor body and the heat outlet shell 3 can be shifted further towards the grounding end 33 of the heat outlet shell 3, so as to maintain the normal heat outlet function of the mobile self-balancing reactor.

[0038] In some embodiments, such as Figure 3 As shown, the center of gravity of the heat-exporting outer shell 3 coincides with its geometric center.

[0039] For example, the heat-exporting housing 3 is cylindrical in shape, and its center of gravity coincides with its geometric center, located on the center line of the heat-exporting housing 3.

[0040] In this situation, the overall center of gravity of the reactor body has shifted towards the grounding end 33 of the heat outlet shell 3. The center of gravity of the heat outlet shell 3 is located on the center line of the heat outlet shell 3. Therefore, the center of gravity of both the reactor body and the heat outlet shell 3 is still shifted towards the grounding end 33 of the heat outlet shell 3, thus maintaining the normal heat outlet function of the mobile self-balancing reactor.

[0041] The above settings can simplify the structural design of the heat export casing 3.

[0042] In some embodiments, such as Figure 3 and Figure 5 As shown, the heat-exporting outer shell 3 has an annular cross-sectional shape. The material of the heat-exporting outer shell 3 is a homogeneous material.

[0043] For example, the material at different locations of the heat-exporting housing 3 is stainless steel.

[0044] With the above settings, the center of gravity of the heat export shell 3 can be made to coincide with its geometric center, which simplifies the design and manufacturing difficulty of the heat export shell 3.

[0045] In some embodiments, the center of gravity of the heat-exporting housing 3 is biased toward the ground terminal 33 of the heat-exporting housing 3.

[0046] Based on this, it is easier to shift the center of gravity of both the reactor body and the heat extraction shell 3 more towards the grounding end 33 of the heat extraction shell 3, so as to maintain the normal heat extraction function of the mobile self-balancing reactor.

[0047] In some embodiments, such as Figure 6 As shown, the heat-exporting casing 3 has an annular cross-sectional shape. The average density of the material at the grounding end 33 of the heat-exporting casing 3 is greater than the average density of the material at the exhaust end 31 of the heat-exporting casing 3.

[0048] For example, such as Figure 6 As shown, the portion between the grounding end 33 and the exhaust end 31 of the heat extraction shell 3 is the connecting portion 32. The average density of the material of the connecting portion 32 can be greater than the average density of the material of the exhaust end 31 of the heat extraction shell 3, but less than the average density of the material of the grounding end 33 of the heat extraction shell 3. That is, after the heat extraction shell 3 drives the reactor body to a stable state, the average density of the material of the heat extraction shell 3 gradually decreases from bottom to top.

[0049] Understandably, through the above settings, the mass of the grounding end 33 of the heat outlet casing 3 can be made greater than the mass of the exhaust end 31, and the center of gravity of the heat outlet casing 3 can be made more biased towards the grounding end 33 of the heat outlet casing 3. This makes it easier to make the center of gravity of both the reactor body and the heat outlet casing 3 biased towards the grounding end 33 of the heat outlet casing 3. In addition, the regular shape of the heat outlet casing 3 simplifies the design difficulty of the heat outlet casing 3.

[0050] In some embodiments, such as Figure 7 As shown, the cross-sectional shape of the heat-exporting outer shell 3 is smaller at the top and larger at the bottom. The material of the heat-exporting outer shell 3 is a homogeneous material, or the average density of the material in the lower part of the heat-exporting outer shell 3 is greater than the average density of the material in the upper part of the heat-exporting outer shell 3.

[0051] like Figure 7 As shown, the cross-sectional shape of the heat outlet shell 3 is similar to that of a roly-poly toy. At this time, regardless of whether the material of the heat outlet shell 3 is a homogeneous material or the average density of the material at the bottom of the heat outlet shell 3 is greater than the average density of the material at the top of the heat outlet shell 3, the mass of the bottom of the heat outlet shell 3 can be greater than the mass of the top of the heat outlet shell 3, causing the center of gravity of the heat outlet shell 3 to shift downward, that is, the center of gravity of the heat outlet shell 3 to shift towards the grounding end 33. This makes it easier for the center of gravity of both the reactor body and the heat outlet shell 3 to shift towards the grounding end 33 of the heat outlet shell 3.

[0052] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a second gas flow channel 7 is formed inside the heat export casing 3. The second gas flow channel 7 has a second air inlet 8 and a second exhaust port. The second exhaust port is connected to the first air inlet 4 and is isolated from the outside air, so that all the gas entering the first gas flow channel 6 flows into the second gas flow channel 7. The second air inlet 8 is located at the exhaust end 31 of the heat export casing 3.

[0053] It should be noted that the second exhaust port is isolated from the outside air after it is connected to the first air intake port 4. (Comparison) Figure 3 and Figure 5 The connection point between the second exhaust port and the first air inlet 4 is isolated from the outside air by the outer wall of the heat dissipation casing 3. Outside air can only enter the second gas flow channel 7 through the second air inlet 8, then enter the first gas flow channel 6 through the connection point between the second exhaust port and the first air inlet 4, and finally exit from the first exhaust port 5 of the first gas flow channel 6. Except for the second air inlet 8 and the first exhaust port 5, other locations in the first gas flow channel 6 and the second gas flow channel 7 are not connected to the outside.

[0054] With the above configuration, the first gas channel 6 and the second gas channel 7 can be interconnected at the grounding end 33 of the heat extraction shell 3. After the heat extraction shell 3 drives the reactor body to a stable state, the openings of the first gas channel 6 and the second gas channel 7 are both located at the top of the heat extraction shell 3, and the connection point of the first gas channel 6 and the second gas channel 7 is isolated from the outside air. This can prevent the water level from rising during rainy weather and causing the water to flow through the original first air inlet 4 ( Figure 3 The first air inlet 4) enters the first gas flow channel 6 and affects the gas circulation in the first gas flow channel 6, thus ensuring the normal heat removal function of the mobile self-balancing reactor.

[0055] In some embodiments, such as Figure 8 As shown, after the heat removal shell 3 and the reactor body are converted to a stable state, the second air inlet 8 and the first exhaust port 5 are both oriented diagonally downwards.

[0056] With the above-mentioned setup, there is a structural shield above the second air inlet 8 and the first exhaust outlet 5, which can prevent rainwater from falling into the first gas flow channel 6 and the second gas flow channel 7 on rainy days. This avoids affecting the flow of gas in the first gas flow channel 6 and the second gas flow channel 7, and ensures that the airflow in the first gas flow channel 6 and the second gas flow channel 7 can perform the normal heat removal function of the mobile self-balancing reactor.

[0057] In some embodiments, such as Figure 8As shown, there are multiple first gas flow channels 6 and multiple second gas flow channels 7. The first air inlets 4 of the multiple first gas flow channels 6 and the second exhaust ports of the multiple second gas flow channels 7 are all interconnected.

[0058] Multiple first gas channels 6 and second gas channels 7 are distributed in parallel along the longitudinal direction of the heat outlet shell 3 (the direction in which the center line of the heat outlet shell 3 is located), and are separated from each other by guide plates.

[0059] The above settings can reduce the impact of uneven temperature in the horizontal reactor on the natural circulation efficiency of the gas in the first gas channel 6, which is caused by the gas flow along the centerline of the horizontal reactor. This improves the heat dissipation capacity of the reactor body.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
