Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1-7 As shown, a packaging container for spent fuel-related components includes a container body 1 and a container cover 2, wherein the container body 1 adopts an external dimension that matches the fuel assembly, and is convenient to be finally placed on the fuel grid of the spent water pool. The container body 1 includes The square tube 13 of the square cylinder structure and the base 12 on the left side of the square tube 13 that closes the square tube 13 are provided with reinforcing ribs 11 on the base 12, and a number of foreign matter discharge holes 15 are opened on the base 12, and the apertures are smaller than the relevant The rod diameter of the component is used to prevent the activator from depositing at the bottom of the container; there are several drainage holes on the four sides of the square tube ...

The invention relates to the technical field of storage, packaging and transportation used after volume shrinkage of a spent fuel associated assembly, and particularly discloses a spent fuel associated assembly packaging container. The packaging container comprises a container body and a container cover. The center of an upper end container cover body in the container cover is provided with a hole. A supporting shaft penetrates through the center hole of the upper end container cover body and then is fixedly connected with a cross located below the upper end container cover body. The supporting shaft is externally sleeved with a limiting base fixed to the upper end container cover body. The limiting base is provided with a U-shaped groove with one side communicating with the edge of the limiting base and the other side not communicating with the edge of the limiting base. A stop pin is arranged in the U-shaped groove of the limiting base and is tightly butted through a compression spring between the supporting shaft and the limiting base. The stop pin can drive the cross to rotate, and the container cover on the container body can be locked or separated through the cross through the cross when the container cover covers the container body. The spent fuel associated assembly packaging container and a container end cover are connected into a whole at the position of a cover opening mechanism. After uncovering, the container cover can be dismantled, an opening of the container is large and thus the associated assembly subjected to volume shrinkage can be stored conveniently.
Description
technical field [0001] The invention belongs to the technical field of storage, packaging and transshipment of spent fuel-related components after shrinkage, and in particular relates to a packaging container for spent fuel-related components. Background technique [0002] After the spent fuel assembly shrinks, it is necessary to transfer the disassembled related components from the spent water pool to the spent water pool grid. Since there is a considerable distance between the spent water pool and the spent water pool grid, it is necessary to design a storage container that is convenient for hoisting. After the existing storage container is opened, the upper container cap still remains on the container body, so that the size of the opening of the container body is too small so that components such as flanges cannot be put in. Contents of the invention [0003] The purpose of the present invention is to provide a packaging container for spent fuel-related components, whic...
