Description

Technical Field

[0001] The invention relates to the technical field of spent fuel management, and in particular to a dynamic management system for a spherical spent fuel storage process room. Background Art

[0002] The total amount of spent fuel discharged from power reactors in the world is about 10,500 tons per year. In some countries, this spent fuel is reprocessed and used as a recyclable energy source. In some countries, due to technical limitations and public willingness, the spent fuel management strategy is to temporarily store it without reprocessing or disposal. Therefore, countries with nuclear power projects usually adopt different forms of spent fuel management. In general, there are three main ways to manage spent fuel: direct disposal, reprocessing and export.

[0003] Like other engineering systems, the safe operation and maintenance of spent fuel storage facilities or process rooms depend to a certain extent on proper design and construction. Therefore, the design of spent fuel storage facilities or process rooms in nuclear power plants must have specific functions to prevent subcriticality, heat dissipation, shielding and other functions.

[0004] For the pebble bed reactor nuclear power plants that have been put into operation, the spent fuel storage process room in the plant adopts dry storage. After the spherical spent fuel elements are sorted as spent fuel after the burnup measurement, they are discharged into the spent fuel tanks in the shaft of the spent fuel storage process room. During the loading process, the spent fuel tanks are placed in the shielding cover on the ground vehicle. After the loading is completed, the shielding cover of the ground vehicle is transported to the target shaft, and the tank lifting mechanism and tank lifting device on the shielding cover are lifted to the shaft of the spent fuel storage room for stacking and storage.

[0005] The capacity of all spent fuel storage tanks is the number of all fuel spheres in the full life cycle of the pebble bed core. The capacity of a single storage tank is the average of the total capacity according to the number of storage tanks. When a single storage tank reaches its designed capacity, the tank will be welded and sealed by a ground vehicle and then hoisted and transported.

[0006] The loading, transportation and hoisting of spent fuel in the pebble-bed nuclear power plants that have been put into operation are all completed by ground vehicles. These processes have safety hazards and potential problems. First of all, due to the heavy weight, strong decay heat and radioactivity of the filled and sealed spent fuel tanks, there is a risk of hoisting accidents of the spent fuel storage tanks during the hoisting process of the ground vehicle, causing radioactive contamination. Secondly, the ground vehicle is frequently operated in the spent fuel storage process room, with almost no pause time, and it comes into contact with radioactive fuel balls. The surfaces of the various structures of the ground vehicle, especially the dead corners, are easily covered with radioactive dust, making subsequent repair and maintenance difficult. In addition, the spent fuel storage tanks that have completed intermediate storage need to be hoisted out of the shaft by ground vehicles and then transported. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a dynamic management system for a storage spherical spent fuel process room, including a storage component 100, a receiving tube component 200 and a transfer component; wherein the storage component 100 is used to store spent fuel, and includes a storage tank 101; the receiving tube component 200 is used to provide a storage space for the storage tank 101 storing spent fuel; and the transfer component is used to transfer the storage tank 101.

[0033] Specifically, the storage tank 101 is cylindrical, and the height of the storage tank 101 is denoted as H0. The interior of the storage tank 101 has a storage cavity for storing spent fuel and is open at the top. A protective cover 102 for sealing the storage tank 101 is provided at the top opening of the storage tank 101. The protective cover 102 is made of shielding material, and the thickness of the protective cover 102 is denoted as L0.

[0034] Furthermore, the collection tube assembly 200 includes a spent fuel storage room 201 which is hollow inside, and a grid shaft 203 extending below the ground surface is provided inside the spent fuel storage room 201 , and the storage tank 101 is stored in the grid shaft 203 .

[0035] Furthermore, the transfer assembly includes a tractor 301 arranged in the spent fuel storage room 201, a grid frame 302 arranged inside the grid shaft 203, and a buffer push rod 303 arranged at the bottom of the grid shaft 203; wherein the tractor 301 is used to control the transfer of the storage tank 101 or move the storage tank 101 out of the spent fuel storage room 201, the grid frame 302 is used to carry the storage tank 101, and the buffer push rod 303 is used to control the vertical lifting of the grid frame 302.

[0036] Specifically, the height of the grid frame 302 is recorded as H3 (H3=H0+L0). As a tool for supporting the storage tank 101, it has super-large weight-bearing capacity and anti-deformation ability. It can simultaneously withstand the gravity of the storage tank 101 and the thrust of the buffer push rod 303 when it is extended, and maintain structural stability.

[0037] Specifically, the buffer push rod 303 is a multi-section push rod, including a multi-section folding portion 303a, and a buffer seat 303b arranged on the top of the multi-section folding portion 303a, the buffer seat 303b is made of shielding material, and serves as a bottom shielding protection layer for the storage tank 101, and the top of the buffer seat 303b is against the bottom of the grid frame 302; a plurality of storage units 304 are evenly arranged at the bottom of the grid frame 302, and the number of storage units 304, buffer push rods 303, and storage tanks 101 is the same, and each storage tank 101 is placed on a corresponding storage unit 304, and a buffer push rod 303 is arranged at the bottom of each storage unit 304.

[0038] When in use, the grid frame 302 and the storage tank 101 are lifted and lowered by controlling the buffer push rod 303 to extend and retract, so as to realize the transfer of the storage tank 101 between the spent fuel storage room 201 and the grid shaft 203. The full length of the buffer push rod 303 is recorded as L1 (L1=H0). In this way, when the buffer push rod 303 is in a fully extended state, the buffer tank will be pushed to a position flush with the ground. At this time, the buffer push rod 303 is kept stable, so that the tractor 301 can pull the storage tank 101 out of the spent fuel storage room 201.

[0039] In summary, the buffer push rod 303 extends to push the grid frame 302 from the grid shaft 203 into the spent fuel storage room 201, and the storage tank 101 in the spent fuel storage room 201 is transferred to the grid frame 302 by the tractor 301. Subsequently, the extended buffer push rod 303 is slowly retracted, and under the action of gravity, the storage tank 101 and the grid frame 302 sink into the grid shaft 203, realizing the underground storage of the storage tank 101, that is, the underground storage of the spent fuel. The grid shaft 203 is a storage tank 101 accommodation space, and at the same time, this accommodation space provides air for the storage tank to facilitate convection cooling.

[0040] Example 2

[0041] Reference Figure 1 and Figure 2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the wall of the spent fuel storage room 201 is a prefabricated building, which includes an upper wall 201a and a lower wall 201b connected to the upper wall 201a by mortise and tenon joints; wherein the height of the upper wall 201a is denoted as H1, and the height of the lower wall 201b is denoted as H2.

[0042] Specifically, the upper wall 201a is a mortise and tenon structure, and the lower wall 201b is a tenon and mortise structure adapted to the upper wall 201a; and the lower wall 201b is embedded with a steel plate or steel frame having the same structural shape as the lower wall 201b. The assembled design of the upper wall 201a and the lower wall 201b not only ensures the strength and shielding effect of the spent fuel storage room 201, but also provides convenience for the removal of equipment during the later decommissioning stage of the site.

[0043] Furthermore, an arch door 202 is provided on any side wall of the lower wall 201b, and the height of the arch door 202 is denoted as h (h=H0+Δ1, wherein Δ1 is the difference between the height of the arch door 202 and the height of the storage tank 101). Furthermore, the arch door 202 serves as a moving passage for the transfer and removal of the storage tank 101, and the opening direction of the arch door 202 should be consistent with the orientation of the spent fuel transfer room.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3

[0046] Reference Figure 1 and Figure 3 to Figure 5 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that an annular toothed outer edge 103 is provided on the outside of the storage tank 101, and a spherical rolling body 104 is movably provided on the bottom of the storage tank 101 to assist the movement of the storage tank 101.

[0047] Furthermore, the tractor 301 includes a cylindrical body 301a, an electric control wheel 301b movably disposed at the bottom of the body 301a, and a locking toothed ring 301c disposed outside the body 301a; wherein the electric control wheel 301b is used to control the movement of the body 301a, and the locking toothed ring 301c can be engaged with the annular toothed outer edge 103 and control the movement of the storage tank 101 in the form of a push box. When in use, the storage tube tank is docked with the tractor 301 by engaging the annular toothed outer edge 103 with the locking toothed ring 301c.

[0048] Specifically, at least two tractors 301 should be provided in the spent fuel storage room 201. During transportation, the locking toothed rings 301c on the two tractors 301 are engaged with the annular toothed outer edge 103 on the same storage tank 101 to control the movement and reversal of the storage tank 101. During movement, the two tractors 301 are arranged on both sides of the storage tank 101 in a symmetrical structure and move in a specified direction, driving the storage tank 101 to move to a specified position in the form of a box pusher; during reversal, one of the tractors 301 does not move to lock the storage tank 101, and the other tractor 301 uses the gears between the annular toothed outer edge 103 and the locking toothed ring 301c to move to the reversal position in a circular motion.

[0049] The transfer assembly also includes a channel vehicle 305 disposed on the top of the spent fuel storage room 201, and the protective cover 102 is provided with a vertical hook 105 that can cooperate with the claws on the channel vehicle 305. After the storage tank 101 is moved into the grid frame 302, the protective cover 102 can be added to the storage tank 101 through the channel vehicle 305 to seal the top opening of the storage tank 101 and keep the ground inside the spent fuel storage room 201 level. At the same time, the protective cover 102 is made of shielding material, and after being added to the storage tank 101, it can serve as a top shielding protection layer of the storage tank 101.

[0050] The remaining structure is the same as that of Example 2.

[0051] In summary, the outlet of the discharge pipe is located above the mouth of the storage tank 101, and the opening on the top of the storage tank 101 is the inlet for the spent fuel elements. The spent fuel falls from the outlet of the discharge pipe into the storage tank 101. When the amount of spent fuel in the storage tank 101 reaches the designed capacity, the storage tank 101 is moved to the storage unit 304 of the grid frame 302 by ground translation in the form of a box pusher by two tractors 301. Then the buffer push rod 303 is controlled to slowly contract, and under the action of gravity, the storage tank 101 and the grid frame 302 sink into the grid shaft 203, and then the protective cover 102 is installed on the upper opening of the storage tank 101 by the channel vehicle 305 to complete the physical sealing of the storage tank 101. At the same time, when the buffer push rod 303 is retracted, the two tractors 301 are moved and controlled to go to the empty storage tank 101 area, and a new, empty storage tank 101 is moved into place, ensuring that the discharge pipe outlet is above the tank mouth of the storage tank 101.
