Embodiment Construction

[0047] First refer to figure 1 , figure 1 A container 1 for transporting and / or storing (preferably) spent nuclear fuel assemblies is shown.

[0048] The container 1 generally comprises a packaging assembly 2, which is the object of the present invention, inside which is arranged a storage device 4, which is also called a storage basket. Such as figure 1 As schematically shown in , the storage device 4 is arranged to be arranged in the accommodating cavity 6 of the package assembly 2, from figure 1 The longitudinal axis 8 of the packaging assembly can also be seen in the figure, the longitudinal axis 8 being coaxial with the longitudinal axis of the storage device and the accommodating cavity.

[0049] Throughout the description, the term "longitudinal" should be understood as being parallel to the longitudinal axis 8 and the longitudinal direction of the packaged assembly.

[0050] The container 1 and the storage device 4 forming the housing for accommodating the nuclear ...

Abstract

The invention relates to a thermal conductor (16) for an inter-wall space (14) of a lateral body of a container (2) for transporting and / or storing radioactive materials, the conductor (16) comprising a member (30) crossing the inter-wall space (14) and a connecting member (32) that bears against one (20) of the internal and external walls of the lateral body, the member (32) having points (36) for fastening to the wall (20) spaced apart from each other along a longitudinal direction of the conductor. According to the invention, the member (32) is split into segments along the longitudinal direction so as to define sections (32a) separated from each other by slits (40) arranged between the fastening points (36), each slit (40) extending through the strut member (30) and defining a closed end of this slit.

Description

technical field [0001] The invention relates to the field of packaging for the transport and / or storage of radioactive material, preferably of the spent nuclear fuel assembly type. Background technique [0002] Usually, to ensure the transport and / or storage of radioactive materials, storage devices are used, also known as "storage baskets" or "storage racks". These storage devices, generally having a cylindrical shape and a generally circular or polygonal cross-section, are capable of containing radioactive material. The storage device is accommodated in the cavity of the packaging assembly to form together with the packaging assembly a container for transporting and / or storing radioactive material, the radioactive material being completely enclosed in the formed container. [0003] The above-mentioned cavity is generally defined by a side extending along the longitudinal axis of the packaging assembly, and a bottom and a cover arranged at opposite ends of the side along t...
