Detailed Description
For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 and 2, the layout structure of the spent fuel transportation factory building according to an embodiment of the present invention includes loading wells 10, preparing wells 20 and lifting holes 30 arranged in a row.
In a spent fuel transportation plant of a nuclear power plant, a loading well 10 is located at one side of a spent fuel pool 100, so that the spent fuel pool 100, the loading well 10, a preparation well 20 and a lifting hole 30 are also arranged in a line.
The spent fuel pool 100 is used as a place for storing spent fuel during the operation of a nuclear power plant, the loading well 10 is used as a place for canning the spent fuel into the spent fuel transportation container 200, the preparation well 20 is used as a place for cleaning and checking the spent fuel transportation container 200 and other operations, and the lifting hole 30 is used as a place for entering and exiting the factory building with new fuel, the spent fuel transportation container 200 and other PMC (nuclear fuel loading and unloading and storing system) equipment.
Buffer layers are respectively arranged below the loading well 10, the preparation well 20 and the lifting hole 30, so that the buffer requirement of dropping the spent fuel transport container 9m is met. The buffer layers are divided into a first buffer layer 11, a second buffer layer 21 and a third buffer layer 31, wherein the first buffer layer 11 is arranged below the loading well 10, the second buffer layer 21 is arranged below the preparation well 20, and the third buffer layer 31 is arranged below the lifting hole 30. The elevation of the third buffer layer 31 below the hoist hole 30 may be, but is not limited to, -4.900m.
The material, thickness, etc. of each buffer layer can be respectively referred to the requirements and actual demands of the prior art.
Typically, the inner bottom surface of the loading well 10 forms a load floor upon which the spent fuel transport vessel 200 is placed. In the invention, the loading well 10 is internally provided with the transfer platform 40 which is higher than the bearing bottom surface of the loading well 10, so that the spent fuel transport container 200 is hoisted into the preparation well 20 from the transfer platform 40, the hoisting height is smaller than 9m, and the hoisting height is further within the anti-drop capability of 9m of the spent fuel transport container 200 test.
In combination with the arrangement of the transfer platform 40 in the loading well 10, a first buffer layer 11 is arranged below the loading bottom surface, and a platform buffer layer 12 is arranged below the transfer platform 40.
In this embodiment, as shown in FIG. 1, the loading well 10 and the preparation well 20 are adjacently connected by a partition wall 22. The transfer platform 40 is connected to one side of the partition 22 located in the loading well 20, and the height of the partition 22 on the transfer platform 40 is less than 9m, so that the spent fuel transport container 200 on the transfer platform 40 is lifted, and can cross the partition 22 to enter the preparation well 20 at a height of less than 9 m.
In addition, the height of the transfer platform 40 relative to the bearing bottom surface is also less than 9m, so that the spent fuel transport container 200 is lifted from the bearing bottom surface to the transfer platform 40, and the spent fuel transport container is not required to be lifted to a height above 9m, namely, the lifting height is within the drop resistance of 9m of the spent fuel transport container 200 test.
Specifically, in the embodiment shown in fig. 1, the elevation of the loading bottom surface of the loading well 10 is +4.800m, and the elevation of the transfer platform 40 is +12.00m, that is, the spent fuel transport container 200 is lifted from the loading bottom surface to the height of 7.2m on the transfer platform 40.
It is understood that the elevation of the transfer platform is not limited to 12m, and can be flexibly set in the range of 11.5m-12.5 m.
The preparation well 20 and the lifting hole 30 are adjacently connected, and communication or separation is realized between the preparation well and the lifting hole through the gate 50. In a state that the gate 50 is opened to communicate the preparation well 20 and the lifting hole 30, the spent fuel transport container 200 in the preparation well 20 can be translated into the lifting hole 30 through the gate 50, so that the spent fuel transport container 200 can be transferred without lifting the spent fuel transport container by a sufficient height, and the elevation of the inner bottom surface of the preparation well 20 can be not limited to 9m or less.
Alternatively, the shutter 50 may be opened and closed by a drawing method, a lifting method, a folding method, or the like. For example, when the preparation well 20 and the lifting hole 30 are required to be communicated, the gate 50 is pulled up, so that a through hole is formed in the original position of the gate 50, and the spent fuel transportation container 200 passes through and enters the lifting hole 30. After the transfer is completed, the shutter 50 is lowered to isolate the preparation well 20 from the lifting hole 30.
Or when the preparation well 20 and the lifting hole 30 are required to be communicated, the gate 50 is downwards placed to enter the interlayer of the lower wall body, so that a through hole is formed in the original position of the gate 50, and the condition that the spent fuel transport container 200 passes through the lifting hole 30 is met. After the transfer is completed, the shutter 50 is lifted up to isolate the preparation well 20 from the lifting hole 30.
Or the gate 50 can be pulled into the side wall body, and the gate 50 is moved into the side wall body when the preparation well 20 and the lifting hole 30 are required to be communicated, so that a through hole is formed in the original position of the gate 50, and the condition that the spent fuel transport container 200 passes through the lifting hole 30 is met. After the transfer is completed, the gate 50 is pulled out from the side wall body to isolate the preparation well 20 from the lifting hole 30.
Or the gate 50 is realized by adopting a foldable gate, and the gate 50 is folded and retracted to one side when the preparation well 20 and the lifting hole 30 are required to be communicated, so that a through hole is formed in the original position of the gate 50, and the condition that the spent fuel transport container 200 passes through and enters the lifting hole 30 is satisfied. After the transfer is completed, the shutter 50 is opened to isolate the preparation well 20 from the hoist hole 30.
The above opening and closing of the gate 50 can be realized by adopting a corresponding driving mechanism, so that manual operation is reduced.
Further, in order to finish the overturning of the spent fuel transport container 200 at a fixed point below the lifting hole 30 and place the spent fuel transport container on the transport vehicle 30 in a flat state, the inner dimension of the lifting hole 30 is enlarged, so that the inner peripheral dimension of the lifting hole 30 is enough to meet the overturning of the spent fuel transport container 200 from vertical placement to flat placement.
In this embodiment, the length and width of the lifting hole 30 are respectively increased, so that the length and width of the lifting hole 30 are respectively 5.5m and 6.5m.
Still further, the layout structure of the spent fuel transportation factory building of the present invention may further comprise a first operation platform 60 disposed on the transfer platform 40 and surrounding the spent fuel transportation container 200, so that an operator can perform operations such as bolt fastening, inflation and drainage, vacuum drying, helium filling, sealing and detection on the spent fuel transportation container 200 on the first operation platform 60.
Preferably, the first operating platform 60 may be attached to the inner wall surface of the partition 22. The side of the first operation platform 60 facing away from the partition wall 22 may be provided with an arc-shaped recess matching with the outer circumferential surface of the spent fuel transportation container 200, so that the first operation platform 60 approaches the spent fuel transportation container 200 through the recess, and an operator may perform operations such as bolt fastening, air-filling and water-draining, vacuum drying, helium-filling, sealing and detecting on the spent fuel transportation container 200 on the edge of the recess.
The concave arrangement on the first operation platform 60 also makes it not surround the whole periphery of the spent fuel transportation container 200, but a part of the arc periphery, so that the spent fuel transportation container 200 is not affected to be lifted or lowered, and the first operation platform 60 can be fixed on the transfer platform 40 as a fixing facility without repeated disassembly and assembly.
The layout structure of the spent fuel transportation factory building of the invention can also comprise a second operation platform 70 which is arranged in the preparation well 20 and can be arranged around the periphery of the spent fuel transportation container 200, so that an operator can conveniently perform operations such as bolt fastening, inflation and drainage, vacuum drying, helium filling, sealing and detection on the spent fuel transportation container 200 on the second operation platform 70.
The second operating platform 70 is preferably removably positioned so as not to interfere with translation of the spent fuel transport vessel 200 through the gate 50 into the lifting aperture 30. After the spent fuel transport container 200 is suspended to the preparation well 20, the second operation platform 70 is installed, and an operator performs operations such as bolting, air-filling and draining, vacuum drying, helium-filling, seal detection, etc. on the spent fuel transport container 200 on the second operation platform 70. Before hoisting the spent fuel transport vessel 200 to the hoist aperture 30, the second operational platform 70 is removed or lifted off the preparation well 20, allowing room for translation of the spent fuel transport vessel 200.
In the layout structure of the spent fuel transportation factory building of the invention, the first operation platform 60 and the second operation platform 70 can respectively adopt steel structures. In addition, guardrails are further arranged on the first operation platform 60 and the second operation platform 70 respectively, so that operators are protected to a certain extent, and dangers such as falling are avoided.
The layout structure of the spent fuel transportation factory building ensures that each step in the hoisting operation process of the spent fuel transportation container 200 is smaller than 9m, thereby meeting the 9m drop test requirement of the existing spent fuel transportation container without adding additional test identification and the like.
In addition, through the improvement to the size of the lifting hole 30, the fixed-point overturning requirement during receiving and outward transportation of the spent fuel transportation container 200 is met, and the risk brought by the cooperation overturning of the lifting device 400 (such as a crane) and the transportation vehicle 300 is avoided.
In this regard, referring to fig. 1 and 2, the method for hoisting the spent fuel transportation container implemented in the layout structure of the spent fuel transportation factory building of the present invention may include the following steps:
s1, connecting the hoisting equipment 400 with the spent fuel transportation container 200 on the bearing bottom surface in the loading well 10.
Prior to step S1, spent fuel is previously loaded from the spent fuel pool 100 into the spent fuel transport vessel 200, and the canning operation is mainly performed in the loading well 10.
After spent fuel canning and completion, the spent fuel transport vessel 200 is primarily placed on the load floor within the loading well 10.
The layout structure of the spent fuel transportation factory building can be used for both a fuel floor crane and an overhead crane.
S2, lifting the spent fuel transport container 200 and placing the spent fuel transport container on a transfer platform 40 in the loading well 10, wherein the lifting height is less than 9m.
Specifically, the spent fuel transport container 200 on the loading floor is lifted on the transfer platform 40 within the loading well 10 by the lifting apparatus 400. Because the elevation difference between the elevation of the transfer platform 40 and the elevation of the bearing bottom surface is smaller than 9m, the lifting height of the spent fuel transportation container 200 is also smaller than 9m, and the lifting height is within the drop resistance of 9m of the spent fuel transportation container 200 test.
S3, lifting the spent fuel transportation container 200 from the transfer platform 40, leaving the loading well 10 and moving to the position above the preparation well 20, and lowering the spent fuel transportation container 200 into the preparation well 20.
The spent fuel transport vessel 200 is lifted from the transfer platform 40 by the lifting apparatus 400 to a height of less than 9m. The height of the bond barrier 22 is typically less than 9m and typically in the range of 4.5m-6m, so the lifting height is also less than 9m, which is within 9m of the drop resistance of the spent fuel transport vessel 200 test.
S4, after the gate 50 between the preparation well 20 and the lifting hole 30 is opened, the spent fuel transportation container 200 is lifted and translated into the lifting hole 30.
After the gate 50 is opened, the spent fuel transport container 200 is lifted off the bottom surface of the preparation well 20 by the lifting apparatus 400 and then translated into the lifting hole 30.
After the transfer of the spent fuel transport vessel 200 is completed, the shutter 50 may be lowered to isolate the preparation well 20 from the lifting hole 30.
The gate 50 may be opened and closed by a drawing method, a lifting method, a folding method, or the like. Alternatively, in this step, when the preparation well 20 and the lifting hole 30 need to be communicated, the gate 50 is lowered to enter the interlayer of the lower wall, so that a through hole is formed in the original position of the gate 50, and the spent fuel transport container 200 passes through and enters the lifting hole 30. After the transfer is completed, the shutter 50 is lifted up to isolate the preparation well 20 from the lifting hole 30.
Or the gate 50 can be pulled into the side wall body, and the gate 50 is moved into the side wall body when the preparation well 20 and the lifting hole 30 are required to be communicated, so that a through hole is formed in the original position of the gate 50, and the condition that the spent fuel transport container 200 passes through the lifting hole 30 is met. After the transfer is completed, the gate 50 is pulled out from the side wall body to isolate the preparation well 20 from the lifting hole 30.
Or the gate 50 is realized by adopting a foldable gate, and the gate 50 is folded and retracted to one side when the preparation well 20 and the lifting hole 30 are required to be communicated, so that a through hole is formed in the original position of the gate 50, and the condition that the spent fuel transport container 200 passes through and enters the lifting hole 30 is satisfied. After the transfer is completed, the shutter 50 is opened to isolate the preparation well 20 from the hoist hole 30.
S5, in the lifting hole 30, the spent fuel transportation container 200 is lowered onto the transportation vehicle 300 at the bottom of the lifting hole 30.
Specifically, the suspended spent fuel transport container 200 is stably lowered by the suspending apparatus 400 within the suspending hole 30 until aligned above the transport vehicle 300 below.
Because the interior of the lifting hole 30 has enough space, the lifting device 400 continues to lower the spent fuel transportation container 200 until the spent fuel transportation container 200 is horizontally placed on the transportation vehicle 300, so that the transportation vehicle 300 and the lifting device 400 do not need to be matched with complex adjustment of overturning the spent fuel transportation container 200, and the risk brought by the complex adjustment is reduced.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
