Abstract
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.
Claims18
Storage device for transporting and/or storing nuclear fuel assemblies, the storage device configured to be housed in the cavity of a container for transporting and/or storing nuclear fuel assemblies, the storage device including a number N of adjacent housings, each intended to receive a nuclear fuel assembly,
- at least some of the N adjacent housings being produced from flat bars with notches, interlocked and stacked along a stacking direction parallel with a central longitudinal axis of the storage device,
- wherein at least one transverse plane of the storage device passing through the N adjacent housings, at least one of these adjacent housings has an inner housing delimiting surface formed in part by:
- a first surface of a first flat bar with notches, the first flat bar produced with boron, and a second surface of the first flat bar opposite the first surface contributes to the formation of the inner housing delimiting surface of one or more others of the N adjacent housings;
- and
- a first surface of a second flat bar with notches, the second flat bar produced without boron, and a second surface of the second flat bar opposite the first surface contributes to the formation of the inner housing delimiting surface of one or more others of the N adjacent housings.
