[0023] Exemplary embodiments of the present application will be described below in conjunction with the accompanying drawings. For the sake of clarity and conciseness, not all features of the actual implementation are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary from implementation to implementation. In addition, it should be understood that although the development work may be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of this application.

[0024] It is also necessary to explain here that, in order to avoid obscuring the present application due to unnecessary details, only the device structure and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, while other details that are not very relevant to the present application are omitted.

[0025] The disclosure below provides a plurality of different embodiments or examples to implement the present application. In order to simplify the disclosure of the present application, the parts and methods of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the present application. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0026] Generally speaking, the liquid in the spent fuel pool will remain stable and is not likely to overflow from the spent fuel pool. However, in extreme cases, such as earthquakes, external forces can cause the spent fuel pool to vibrate, causing the liquid in the pool to sway in different directions. If the shaking reaches a certain amplitude, the liquid may overflow from the spent fuel pool. Technical means are needed to solve this problem in the design and maintenance of spent fuel pools.

[0027] One aspect of an embodiment of the present application provides a device for preventing liquid from sloshing, wherein the liquid is contained in a space for storing spent fuel. Figure 1 A schematic diagram showing that a device for preventing liquid sloshing provided by an embodiment of the present application is located in liquid; Figure 2 FIG. 1 is a schematic diagram showing the structure of a device for preventing liquid sloshing provided in an embodiment of the present application. Figure 1 and Figure 2As shown, the device 100 for preventing liquid from shaking includes a first anti-sway component 10 located in the liquid and a second anti-sway component 20 located in the liquid. The first anti-sway component 10 and the second anti-sway component 20 are fixedly connected. The first anti-sway component 10 and the second anti-sway component 20 are configured to prevent or slow down the shaking of the liquid when the liquid is shaking.

[0028] The device for preventing liquid sloshing provided in the embodiment of the present application has a first anti-sloshing component and a second anti-sloshing component respectively. When the liquid is sloshing, the first anti-sloshing component and the second anti-sloshing component can jointly prevent and slow down the sloshing of the liquid, thereby effectively preventing or slowing down the sloshing of the liquid, and further avoiding the overflow of the liquid from the spent fuel pool due to the sloshing of the liquid.

[0029] The liquid here is generally used to cool the spent fuel, and the liquid will dissolve into the radioactive material.

[0030] In some embodiments, Figure 2 As shown, the first anti-sway assembly 10 includes a main body 11 , a seat body 12 and a sealing member 13 . The main body 11 is fixed to the seat body 12 , and the seat body 12 is fixedly connected to the second anti-sway assembly 20 . Figure 3 yes Figure 2 A schematic cross-sectional view of a device for preventing liquid sloshing is shown in FIG. Figure 3 As shown, the main body 11 is formed with a cavity 111 and an opening 112. A predetermined amount of liquid is injected into the cavity 111 through the opening 112, and the opening 112 is sealed by a seal 13. After the main body 11 is filled with liquid, the shaking of the liquid in the spent fuel pool can be prevented or slowed down when the liquid shakes.

[0031] Since the main body 11 forms a cavity 111, and the cavity 111 is filled with liquid, the density of the main body is increased, so that the main body 11 is more immersed in the liquid in the spent fuel pool, the contact area between the main body 11 and the liquid in the spent fuel pool is increased, and the effect of preventing or slowing down the shaking of the liquid in the spent fuel pool is improved.

[0032] Those skilled in the art may also adopt other methods to increase the contact area between the main body 11 and the liquid. For example, the main body 11 may be solid and a material of suitable density may be selected to allow it to be immersed in the liquid in the spent fuel pool as much as possible.

[0033] In addition, Figure 2In the illustrated embodiment, the main body 11 fluctuates with the liquid in the spent fuel pool. Since the liquid in the cavity 111 does not fill the space of the cavity 111, the liquid in the cavity 111 can fluctuate in the cavity 111, which can absorb the energy brought to the main body 11 by the fluctuation of the liquid in the spent fuel pool, thereby suppressing the splashing of the surface liquid in the spent fuel pool, and further improving the effect of preventing or slowing down the shaking of the liquid in the spent fuel pool in the horizontal direction.

[0034] In some embodiments, the seat 12 is arranged so that the opening 112 of the main body 11 is always facing upward. In this way, the liquid in the spent fuel pool can be prevented from entering the cavity 111, thereby ensuring the stability of the main body 11.

[0035] In some embodiments, the weight of the seat 12 is greater than the weight of the main body 11 when it is not filled with liquid. For example, the main body 11 may be made of a lightweight material or a material with a density slightly greater than the liquid in the spent fuel pool, so that the main body can be suspended in the liquid in the spent fuel pool, and the seat 12 may be made of a material such as aluminum alloy with a density greater than the liquid in the spent fuel pool, so that the weight of the seat 12 is greater than the weight of the main body 11 when it is not filled with liquid, so that the opening 112 of the main body 11 can be kept vertically upward to prevent the liquid in the spent fuel pool from entering the cavity 111 of the main body 11 through the opening 112. In particular, when the density of the material selected for the main body 11 is equivalent to the density of the material selected for the seat 12, the seat 12 can be manufactured integrally with the main body 11. Since the main body 11 has the cavity 111, it is ensured that the seat 12 faces downward and the opening 112 on the main body 11 faces upward.

[0036] In some embodiments, Figure 2 As shown, the second anti-sway assembly 20 includes a first anti-sway component 21 and a second anti-sway component 22. The first anti-sway component 21 and the second anti-sway component 22 are connected by a fixed device. The first anti-sway component 21 and the second anti-sway component 22 are arranged in a staggered plate shape so that they can prevent or slow down the shaking of the liquid in the spent fuel pool when the liquid in the spent fuel pool shakes.

[0037] Since the first anti-sway component 21 and the second anti-sway component 22 are arranged in a staggered plate shape, the liquid in the spent fuel pool will be affected by the additional damping effect provided by the first anti-sway component 21 and the second anti-sway component 22 when shaking, thereby achieving the effect of dissipating the kinetic energy of the shaking of the lower layer of liquid in the spent fuel pool.

[0038] Figure 4 FIG. 1 is a schematic structural diagram of a first anti-sway component and a second anti-sway component of a second anti-sway component of a device for preventing liquid swaying provided in an embodiment of the present application, such as Figure 4As shown, in some embodiments, the first anti-sway member 21 is configured as a semicircular plate, and the second anti-sway member 22 is configured as a semicircular plate. The first anti-sway member 21 forms a first matching groove 211, and the second anti-sway member 22 forms a second matching groove 221. Further, Figure 5 is a schematic diagram of a first anti-swaying member and a second anti-swaying member of a device for preventing liquid swaying provided by an embodiment of the present application, as shown in FIG. Figure 5 As shown, the first matching groove 211 of the first anti-sway component 21 and the second matching groove 221 of the second anti-sway component 22 cooperate with each other to form a staggered plate shape.

[0039] Those skilled in the art may also use partitions of other types and shapes as the first anti-sway member 21 and the second anti-sway member 22. The first anti-sway member 21 and the second anti-sway member 22 may be customized according to the size of the spent fuel pool, for example, a non-porous plate, a grid plate or a perforated plate may be selected, and the shape may be selected according to the pool structure to meet the requirements of different flow characteristics, for example, a semicircular, rectangular, etc. shape may be selected. The first anti-sway member 21 and the second anti-sway member 22 are staggered through the staggered combination of the first matching groove 211 and the second matching groove 221 to form a staggered plate type, so that the second anti-sway assembly 20 can be easily assembled and the assembly process is saved.

[0040] like Figure 2 As shown, the device for preventing liquid sloshing provided by the embodiment of the present application further includes a connector 30, which is configured to fixedly connect the first anti-sloshing assembly 10 with the second anti-sloshing assembly 20. The main body 11 of the first anti-sloshing assembly 10 is configured to be suspended in water, because the weight of the seat 12 is greater than that of the main body 11, and the opening 112 on the main body 11 is kept facing upward. The first anti-sloshing assembly 10 is fixedly connected to the second anti-sloshing assembly 20 by the connector 30, and the second anti-sloshing assembly 20 is arranged below the seat 12. The weight of the second anti-sloshing assembly 20 also plays a role in keeping the opening 112 of the main body 11 facing upward. At the same time, the increase in the weight of the first anti-sloshing assembly 10 by the second anti-sloshing assembly 20 makes the main body 11 with the cavity 111 more stable in the liquid in the spent fuel pool, which can better prevent or slow down the sloshing of the liquid in the spent fuel pool.

[0041] In some embodiments, the connecting member 30 is configured in a cross shape, one side of the cross shape is fixedly connected to the base body 12 , and the other side of the cross shape is fixedly connected to the first anti-sway member 21 and the second anti-sway member 22 .

[0042] Figure 6 is a bottom view schematic diagram of a first anti-sloshing component of a device for preventing liquid sloshing provided in an embodiment of the present application; Figure 7 1 is a bottom view schematic diagram of a connector of a device for preventing liquid sloshing provided in an embodiment of the present application. Figure 6 and Figure 7As shown, the bottom surface of the seat body 12 of the first anti-sway assembly 10 is provided with a seat body matching hole 121, and the connecting member 30 is provided with a connecting matching hole 31; Figure 4 As shown, the first anti-sway component 21 is provided with a first matching hole 212, and the second anti-sway component 22 is provided with a second matching hole 222. The connection matching hole 31 of the connecting component 30 is connected with the seat body matching hole 121 on the bottom surface of the seat body 12 by a fixing device. The first anti-sway component 21 and the second anti-sway component 22 are provided in a staggered plate shape, and are fixed with the connection matching hole 31 of the connecting component 30 by fixing devices through the first matching hole 212 and the second matching hole 222, so that the second anti-sway component 20 in the staggered plate shape is fixed in a cross shape, and the first anti-sway component 10 and the second anti-sway component 20 are also connected in a cross shape, thereby forming the entire device 100 for preventing liquid sloshing. At the same time, the cross shape matches the staggered plate shape formed by the combination of the first anti-sway component 21 and the second anti-sloshing component 22, which is convenient for assembly. The symmetrical state of the device 100 for preventing liquid sloshing formed thereby improves the overall stability of the device 100 for preventing liquid sloshing, ensuring that it can still maintain a relatively stable position during earthquake shaking.

[0043] Another aspect of the embodiment of the present application provides a device for preventing liquid from sloshing. Figure 8 is a schematic diagram of the structure of a device for preventing liquid sloshing according to an embodiment of the present application, such as Figure 8 As shown, the device 200 for preventing liquid sloshing includes a plurality of the aforementioned devices 100 for preventing liquid sloshing, and the plurality of devices 100 for preventing liquid sloshing are arranged in a predetermined manner.

[0044] In some embodiments, the arrangement of the plurality of devices 100 for preventing liquid sloshing is determined by the spacing between the devices and the number of the devices, wherein the distance between the plurality of devices 100 for preventing liquid sloshing is determined according to the depth of the liquid in the spent fuel pool, and the spacing between the devices and the depth of the liquid in the spent fuel pool satisfy the following relationship:

[0045] Device spacing = depth of liquid in the spent fuel pool / 1.6.

[0046] The above relationship can ensure that the device 100 for preventing liquid sloshing is evenly arranged in the spent fuel pool, avoiding interference effect between devices caused by too small a distance between the devices, so as to ensure that the device 200 for preventing liquid sloshing effectively prevents sloshing of liquid in the spent fuel pool.

[0047] In some embodiments, the number of the devices 100 for preventing liquid sloshing included in the apparatus 200 for preventing liquid sloshing is determined according to the total area of ​​the spent fuel pool and the depth of the liquid in the spent fuel pool.

[0048] In some embodiments, technicians in the relevant technical field can preliminarily estimate the number of devices 100 for preventing liquid sloshing that need to be deployed based on experience according to the total area of ​​the spent fuel pool, the projected area and coverage of a single device 100 for preventing liquid sloshing on the horizontal plane.

[0049] In some embodiments, the number of devices 100 for preventing liquid sloshing, the total area of ​​the spent fuel pool, and the depth of the liquid in the spent fuel pool satisfy the following relationship:

[0050]

[0051] Wherein, N is the number of devices 100 for preventing liquid sloshing; A is the total area of ​​the spent fuel pool; and h is the depth of the liquid in the spent fuel pool.

[0052] In some embodiments, the number of devices 100 for preventing liquid sloshing is proportional to the total area of ​​the spent fuel pool and the depth of the liquid therein. Combining the liquid surface area and the depth enables the devices 100 for preventing liquid sloshing to be evenly distributed on the liquid surface of the spent fuel pool, thereby achieving that each device 100 for preventing liquid sloshing can effectively suppress the sloshing of the liquid in the horizontal and vertical directions within its coverage area.

[0053] In some embodiments, the device 200 for preventing liquid sloshing is configured to prevent the liquid in the spent fuel pool from overflowing when the liquid is deformed to the maximum under the action of force.

[0054] In some embodiments, the smaller the stiffness of the liquid in the spent fuel pool, the greater the deformation produced when it is subjected to force, and the greater the level of sloshing of the liquid. Therefore, the number of devices 100 for preventing liquid sloshing included in the equipment 200 for preventing liquid sloshing is set according to the situation where the deformation of the liquid in the spent fuel pool is the largest, which can ensure that the spent fuel pool will not overflow when the stiffness of the spent fuel pool is the smallest, thereby ensuring the safety of the spent fuel pool in extreme situations such as earthquakes.

[0055] In some embodiments, the device 200 for preventing liquid sloshing is configured to maintain uniform liquid flow and pressure distribution in the spent fuel pool.

[0056] As the liquid in the spent fuel pool is subjected to external forces, its internal pressure changes and is transmitted in all directions of the liquid according to the original liquid pressure. Under the action of severe external forces, the uneven pressure inside the liquid may cause liquid splashing. By arranging the device 200 for preventing liquid sloshing, multiple devices 100 for preventing liquid sloshing evenly cover the surface of the liquid in the spent fuel pool, which can produce an additional damping effect, thereby dissipating the kinetic energy of the sloshing of the lower layer of liquid in the spent fuel pool and alleviating the uneven flow and pressure inside the liquid.

[0057] In some embodiments, technicians in the relevant technical field can adjust the number of devices 100 for preventing liquid sloshing based on experience according to the depth of liquid in the spent fuel pool and the draft of the device 100 for preventing liquid sloshing, to ensure that the equipment 200 for preventing liquid sloshing works stably and effectively.

[0058] In some embodiments, multiple devices 100 for preventing liquid sloshing can be connected by steel wires, and multiple devices 100 for preventing liquid sloshing can also be fixedly connected to the periphery of the spent fuel pool, so as to ensure the stability of the device 200 for preventing liquid sloshing in the spent fuel pool, thereby better preventing or slowing down the sloshing of the liquid in the spent fuel pool, and preventing the liquid in the spent fuel pool from overflowing from the spent fuel pool due to sloshing under extreme conditions, such as earthquakes.

[0059] According to the device and equipment for preventing liquid sloshing provided in the present application, when in use, they can be placed in a spent fuel pool, thereby preventing or slowing down the sloshing of the liquid in the spent fuel pool, and preventing the liquid in the spent fuel pool from overflowing from the spent fuel pool due to sloshing under extreme conditions, such as earthquakes.

[0060] Specifically, a plurality of devices 100 for preventing liquid sloshing are distributed on the surface of the spent fuel pool, and the position of the main body 11 in the liquid of the spent fuel pool is adjusted by injecting liquid into the cavity 111, so that the surface of the main body 11 is protruded and flush with the surface of the liquid in the spent fuel pool, thereby maximizing the contact area between the main body 11 and the liquid in the spent fuel pool. The plurality of main bodies 11 fluctuate with the liquid in the spent fuel pool. Since the liquid in the cavity 111 does not fill the space of the cavity 111, the liquid in the cavity 111 can fluctuate in the cavity 111, which can absorb the energy of the main body 11 caused by the fluctuation of the liquid in the spent fuel pool, thereby suppressing the splashing of the surface liquid in the spent fuel pool, and further improving the effect of preventing or slowing down the sloshing of the liquid in the spent fuel pool in the horizontal direction. At the same time, the staggered plate type of the second anti-sloshing component 20 can block the sloshing of the liquid in the spent fuel pool in another direction different from the main body 11 in the spent fuel pool, dissipate the kinetic energy of the liquid in the spent fuel pool, and achieve effective anti-sloshing, thereby avoiding the overflow of the liquid in the spent fuel pool.

[0061] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0062] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
