Embodiment

[0019] Such as figure 1 — image 3 As shown, the nuclear fuel element storage container includes a container shell, a container cover 1, a neutron-absorbing layer, and a cluster element barrel set. The container shell includes a container cylinder 10 and a container bottom plate 7 welded together, and the container cover 1 is fixed to the top plate 2 welded on the inner upper port of the container cylinder 10 by bolts. The neutron-absorbing layer includes a cavity structure 12 welded with the outer wall of the container cylinder 10 and a neutron-absorbing material 11 filled in the cavity formed by welding. The upper and lower ends of the cavity structure 12 are provided with upper and lower limit stops. 9, 13, for fixing the neutron absorbing material 11. The bundle element cylinder group includes 151 regularly arranged cylinders 6, which are used for loading spherical nuclear fuel elements. There is a sealing gasket 2 between the container cover 1 and the cluster element c...

Abstract

The invention discloses a structure of a storage container for a spherical nuclear fuel element, and relates to the field of storage of dangerous goods. The storage container for the spherical nuclear fuel element comprises a container shell, a container cover, a neutron absorbing layer and a bundling element drum group. The storage container for the spherical nuclear fuel element is characterized in that the container shell is formed by connecting a container drum body and a container base plate; an internal end opening in the upper end of the container drum body is provided with a top plate; the container cover is connected with the top plate through a stud; the neutron absorbing layer comprises a cavity structure arranged outside the container drum body and neutron absorbing materials filling in the cavity; the bundling element drum group is arranged inside the container drum body and comprises a plurality of cylinders which are arranged regularly and are used for loading the spherical nuclear fuel element. The storage container for the spherical nuclear fuel element solves the problem that a container which is specially suitable for the storage of the spherical nuclear fuel element and is easy to operate is absent.

Description

technical field [0001] The invention relates to the field of storage of dangerous goods, in particular to a spherical nuclear fuel element storage container. Background technique [0002] The transportation safety of spherical nuclear fuel elements needs to be ensured in the process of transportation and storage, that is, it is necessary to ensure that the spherical nuclear fuel elements are contained in the storage container and will not be scattered outside the container. Therefore, in the design of the storage container, it is necessary to consider selecting a suitable container cylinder structure and container cover structure to ensure the safety of the spherical fuel element inside the container. [0003] In the process of realizing the above-mentioned storage of spherical nuclear fuel elements, the inventors have found that at least the following problems exist in the prior art: [0004] There is a lack of storage containers that are specially suitable for storing sph...
