Abstract
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.
Claims15
A storage device for transporting and/or storing nuclear fuel assemblies, the storage device being to be housed in a cavity of a packaging for transporting and/or storing nuclear fuel assemblies, and including a number N of adjacent housings, each being to receive a nuclear fuel assembly,
- the storage device comprising a plurality of transverse structures spaced apart from each other along a longitudinal direction of the storage device, using a plurality of spacers arranged between these transverse structures, the storage device also comprising sleeves respectively forming the N adjacent housings, each sleeve passing through an opening of at least one of the plurality of transverse structures, each sleeve being made by flat structures along a peripheral direction of the sleeve, each flat structure being parallel to a longitudinal axis of the housing defined internally by the sleeve,
- wherein in a transverse plane of the storage device passing through the N sleeves, at least one of the N sleeves has an internal housing delimitation surface partly formed by:
- an internal surface of a first flat structure thereof made with boron;
- and
- an internal surface of a second flat structure thereof made without boron.
