A storage device for transporting and/or storing nuclear fuel assemblies. The device includes a plurality of transverse structures separated by spacers. Sleeves pass through openings of at least one of the transverse structures. Each sleeve is made from flat structures and forms a housing that can receive a fuel assembly. At least one of these sleeves has an inner recess-delimiting surface formed in part by an inner surface of a first flat structure made with boron and an inner surface of a second flat structure made without boron.

Storage device for nuclear fuel assemblies

A storage device for storing and/or transporting nuclear fuel assemblies. The storage device includes a number N of adjacent recesses. Some of the recesses created by means of notched, intersecting and stacked plates. In at least one transverse plane, at least one of the adjacent recesses has an inner surface which defines the recess. The adjacent recess being formed in part by a first surface of a first notched plate made with boron and a first surface of a second notched plate made without boron.
