Problems solved by technology

It is therefore necessary to provide threaded holes on the inner side of the container cap, thereby sacrificing the stability of the container cap
Furthermore, the manufacture of the hollow cylindrical impact damper and its fastening on the inner side of the container lid require a certain amount of effort

Embodiment Construction

[0031] figure 1 A container according to the invention is shown in , which has a container bottom 2 , a container peripheral wall 3 and a container lid 4 . The container is designed as a hollow cylinder and surrounds an interior 5 in which only the radioactive material 1 indicated by the symbol is located. The container is shown upside down in order to illustrate the state of the lid falling flat. At the moment of impact on the solid ground, the object 1 hits the container lid 4 with a time delay, so that a high force acts on the container lid 4 . The container cover 4 is connected to the container peripheral wall 3 through 24 threaded connections 8 in the form of M36 screw parts. The vessel walls 2, 3, 4 consist of cast iron of grade (quality) GGG 40. The container peripheral wall 3 has a thickness of 160 mm, whereas the container bottom 2 and the container lid 4 have a thickness of 180 mm each. The hollow cylindrical interior 4 has a height of 1140 mm and a diameter of 7...

Abstract

The invention relates to a container for radioactive inventory. The container for radioactive inventory has an end wall, a side wall, and a container lid that form a closed chamber for the radioactive inventory. A plastically deformable layer is provided between the container lid and the inventory and is of such a composition that, in the event of an impact of the inventory against the container lid, at least a majority of the impact forces are uniformly distributable over at least a majority of a surface of the plastically deformable layer.

Description

technical field [0001] The invention relates to a container for containing radioactive articles, and the container includes a container bottom, a peripheral wall of the container and a container cover. A container surrounds an interior cavity for containing radioactive material. Background technique [0002] Such containers are known in principle from practice. In the extreme case, the connection of the container lid to the peripheral wall of the container constitutes a relatively weak point here, since this connection is usually designed to be reversible. A reversible connection is, for example, a screw connection. Due to the very persistent nature of container usage, containers have to be designed for all the different extreme states. This also includes, for example, extreme jolting situations, such as falling from a height of several meters. During such a drop, the potential energy of the container is converted into deformation energy, at which point the screw is subj...
