2) Personnel on the lower part of a crane of the spent fuel pool can not cover the loading well, an auxiliary platform is needed to be used when spent fuel is transported outwards, operation modes are switched when fuel is loaded, and the risk of human error is high.
3) When the spent fuel transport container is received and transported outside, the size of the lifting opening is insufficient, and the container crane and the transport vehicle are matched under the lifting opening to complete the turning operation. Because the crane and the transporter are controlled by different operators and are far apart, there is a risk of incoordination.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail 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, preparation wells 20, and lifting holes 30 arranged in a row.
In a spent fuel transportation plant of a nuclear power plant, the loading well 10 is located at one side of the spent fuel pool 100, so that the spent fuel pool 100, the loading well 10, the preparation well 20 and the lifting holes 30 are also arranged in a straight line.
The spent fuel pool 100 is a place for storing spent fuel during the operation of the nuclear power plant; the loading well 10 is used as a place for loading the spent fuel to the spent fuel transportation container 200; preparing the well 20 as a place for operations such as cleaning and inspecting the spent fuel transport container 200; the lifting hole 30 is used for the places where the new fuel and spent fuel transport container 200 and other PMC (nuclear fuel loading, unloading and storing system) equipment enter and exit the factory building.
Buffer layers are respectively arranged below the loading well 10, the preparation well 20 and the hoisting hole 30, so that the buffer requirement of the spent fuel transport container 9m falling is met. The buffer layers are divided into a first buffer layer 11, a second buffer layer 21 and a third buffer layer 31, 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 hoisting hole 30. The elevation of the third buffer layer 31 below the lifting hole 30 may be, but is not limited to-4.900 m.
The material, thickness and the like of each buffer layer can respectively refer to the setting requirements and actual requirements of the prior art.
Generally, the inner bottom surface of the loading well 10 forms a bearing bottom surface for the spent fuel transport container 200 to be placed thereon. In the invention, the transfer platform 40 higher than the bearing bottom surface of the loading well 10 is arranged in 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 less than 9m, and the hoisting height is within the drop resistance of 9m of the spent fuel transport container 200 test.
The setting of the inside transfer platform 40 of combination loading well 10 is equipped with first buffer layer 11 below the bearing bottom surface, and transfer platform 40 below is equipped with platform buffer layer 12.
In the present 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 wall 22 located in the loading well 20, and the height of the partition wall 22 above the transfer platform 40 is less than 9m, so that the spent fuel transportation container 200 on the transfer platform 40 is lifted and can cross the partition wall 22 to enter the preparation well 20 at a height of less than 9m.
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 transportation container 200 is lifted from the bearing bottom surface and placed on the transfer platform 40 without being lifted to a height of more than 9m, namely, the lifting height is within the 9m drop resistance of the spent fuel transportation container 200 test.
Specifically, in the embodiment shown in fig. 1, the elevation of the bearing bottom surface of the loading well 10 is +4.800m, and the elevation of the transfer platform 40 is +12.00m, that is: the height from the bearing bottom surface to the transfer platform 40 for hoisting the spent fuel transportation container 200 is 7.2 m.
It is understood that the elevation of the transit platform is not limited to 12m, and can be flexibly set within the range of 11.5m-12.5m.
The preparation well 20 and the lifting hole 30 are adjacently connected, and the two are communicated or separated through a 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 transportation container 200 in the preparation well 20 can be translated into the lifting hole 30 through the gate 50, so that the spent fuel transportation container 200 does not need to be lifted to a sufficient height for transferring, and the elevation of the inner bottom surface of the preparation well 20 does not need to be limited to 9m or below.
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 need to be communicated, the gate 50 is pulled up, so that the gate 50 is positioned to form a through opening to allow the spent fuel transportation container 200 to enter the lifting hole 30. After the transfer is completed, the gate 50 is lowered to block the preparation well 20 from the lifting hole 30.
Or, when the preparation well 20 and the hoisting hole 30 need to be communicated, the gate 50 is lowered downwards to enter the interlayer of the lower wall body, so that a through hole is formed in the original position of the gate 50 to allow the spent fuel transport container 200 to enter the hoisting hole 30. After the transfer is completed, the gate 50 is lifted up to block the prepared well 20 from the lifting hole 30.
Or, the gate 50 can be drawn into the sidewall, the preparation well 20 and the lifting hole 30 need to be communicated, and the gate 50 is moved into the sidewall, so that a through hole is formed at the original position of the gate 50, and the spent fuel transport container 200 can enter the lifting hole 30 through the through hole. After the transfer is completed, the gate 50 is pulled out from the sidewall body, and the preparation well 20 is separated from the lifting hole 30.
Or, the gate 50 is realized by a foldable door, when the preparation well 20 and the lifting hole 30 need to be communicated, the gate 50 is folded towards one side, so that a through hole is formed at the original position of the gate 50, and the spent fuel transportation container 200 can enter the lifting hole 30. After the transfer is completed, the gate 50 is opened to block the prepared well 20 from the lifting hole 30.
The opening and closing of the gate 50 can be realized by adopting the corresponding driving mechanism, so that the manual operation is reduced.
Further, in order to realize that the spent fuel transportation container 200 is turned over at a fixed point below the lifting hole 30 and is placed on the transportation vehicle 30 in a flat state, the inner size of the lifting hole 30 is increased in the present invention, so that the inner size of the lifting hole 30 is enough to meet the turning over of the spent fuel transportation container 200 from the vertical position to the flat position.
In this embodiment, the length and the width of the lifting hole 30 are respectively increased, so that the length and the 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 include a first operation platform 60 disposed on the transfer platform 40 and capable of enclosing 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 detection, etc. on the first operation platform 60 for the spent fuel transportation container 200.
Preferably, the first operation platform 60 may be attached to an inner wall surface of the partition wall 22. One side of the first operation platform 60, which is opposite to the partition 22, may be provided with an arc-shaped indent matching the outer circumferential surface of the spent fuel transport container 200, so that the first operation platform 60 is close to the spent fuel transport container 200 through the indent, and an operator may perform operations such as bolt fastening, inflation and drainage, vacuum drying, helium filling, sealing detection, etc. on the edge of the indent.
The concave arrangement of 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 influenced to be hoisted or lowered, and further, 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 plant of the present invention may further include a second operation platform 70 disposed in the preparation well 20 and surrounding the periphery of the spent fuel transportation container 200, so that an operator can perform operations such as bolt fastening, inflation and drainage, vacuum drying, helium charging, sealing detection, etc. on the second operation platform 70 for the spent fuel transportation container 200.
The second operation platform 70 is preferably detachably disposed so as not to interfere with the translation of the spent fuel transport container 200 through the gate 50 into the lifting hole 30. After the spent fuel transport container 200 is hoisted to the preparation well 20, the second operation platform 70 is installed, and an operator performs operations such as bolt fastening, gas charging and water discharging, vacuum drying, helium charging, sealing detection and the like on the spent fuel transport container 200 on the second operation platform 70. Before the spent fuel transport container 200 is hoisted to the hoisting hole 30, the second operation platform 70 is detached or hoisted away from the preparation well 20 to make room for the translation of the spent fuel transport container 200.
In the layout structure of the spent fuel transportation factory building of the present invention, the first operation platform 60 and the second operation platform 70 may be respectively made of steel structures. In addition, the first operating platform 60 and the second operating platform 70 are respectively provided with a guardrail, so that certain protection is provided for operators, and risks such as falling are avoided.
According to the layout structure of the spent fuel transportation plant, each step in the lifting operation process of the spent fuel transportation container 200 is smaller than 9m, the requirements of the existing 9m drop test of the spent fuel transportation container are met, and additional test identification and the like are not needed.
In addition, through the improvement of the size of the lifting hole 30, the requirement of fixed-point overturning during the receiving and outward transportation of the spent fuel transport container 200 is met, and the risk caused by the matching overturning of the lifting equipment 400 (such as a crane) and the transport vehicle 300 is avoided.
In contrast, referring to fig. 1 and fig. 2, the method for hoisting the spent fuel transportation container implemented in the layout structure of the spent fuel transportation plant of the present invention may include the following steps:
s1, connecting the hoisting equipment 400 with the spent fuel transport container 200 on the bearing bottom surface in the loading well 10.
Prior to step S1, the spent fuel is loaded into the spent fuel transportation container 200 from the spent fuel pool 100 in advance, and the canning operation is mainly performed in the loading well 10.
After the spent fuel is canned and completed, the spent fuel transportation container 200 is mainly placed on a load-bearing bottom surface in the loading well 10.
The layout structure of the spent fuel transportation plant can be a fuel landing crane and an overhead crane.
And S2, hoisting the spent fuel transportation container 200 and placing the spent fuel transportation container on the transfer platform 40 in the loading well 10, wherein the hoisting height is less than 9m.
Specifically, the spent fuel transportation container 200 on the bearing bottom surface is hoisted on the transfer platform 40 in the loading well 10 by the hoisting device 400. Because the difference between the elevation of the transfer platform 40 and the elevation of the bearing bottom surface is less than 9m, the hoisting height of the spent fuel transport container 200 is less than 9m, and the hoisting height is within the 9m drop resistance of the spent fuel transport container 200 test.
And S3, hoisting the spent fuel transport container 200 from the transfer platform 40, moving the spent fuel transport container out of the loading well 10 to the position above the preparation well 20, and lowering the spent fuel transport container 200 into the preparation well 20.
The spent fuel transportation container 200 is lifted from the transfer platform 40 by the lifting device 400, and the height of the lifted spent fuel transportation container is less than 9m. The height of the coupling wall 22 is generally set to be less than 9m, and is generally in the range of 4.5m to 6m, so that the lifted height is also less than 9m, and the lifted height is within the 9m drop resistance tested for the spent fuel transport container 200.
And S4, after the gate 50 between the preparation well 20 and the hoisting hole 30 is opened, hoisting and translating the spent fuel transportation container 200 into the hoisting 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 transportation container 200 is completed, the gate 50 may be lowered to block the preparation well 20 from the lifting hole 30.
The gate 50 may be opened or closed by a drawing method, a lifting method, or a folding method. Alternatively, in this step, when it is necessary to communicate the preparation well 20 with the lifting hole 30, the gate 50 is lowered to enter the interlayer of the lower wall, so that the gate 50 is formed with a through hole at its original position to allow the spent fuel transport container 200 to pass through the lifting hole 30. After the transfer is completed, the gate 50 is lifted up to block the prepared well 20 from the lifting hole 30.
Or, the gate 50 can be drawn into the sidewall, the preparation well 20 and the lifting hole 30 need to be communicated, and the gate 50 is moved into the sidewall, so that a through hole is formed at the original position of the gate 50, and the spent fuel transport container 200 can enter the lifting hole 30 through the through hole. After the transfer is completed, the gate 50 is pulled out from the side wall body, and the prepared well 20 and the lifting hole 30 are isolated.
Or, the gate 50 is realized by a foldable door, when the preparation well 20 and the lifting hole 30 need to be communicated, the gate 50 is folded towards one side, so that a through hole is formed at the original position of the gate 50, and the spent fuel transportation container 200 can enter the lifting hole 30. After the transfer is completed, the gate 50 is deployed to block the prepared well 20 from the lifting hole 30.
And S5, in the hoisting hole 30, the spent fuel transport container 200 is lowered onto the transport vehicle 300 at the bottom of the hoisting hole 30.
Specifically, the suspended spent fuel transport container 200 is stably lowered by the lifting apparatus 400 within the lifting hole 30 until aligned above the transport vehicle 300 below.
