A storage rack for nuclear fuel assemblies, comprising a rigid structure defining a plurality of adjacent cells, and comprising in each cell a sleeve defining a cavity intended to receive a nuclear fuel assembly, the sleeve having, in cross-sectional orthogonal to the longitudinal direction, a generally polygonal shape whereof the sides are produced using plates made from a neutron-absorbing material. According to the invention, the sleeve also includes: profiles each forming a corner piece, arranged on at least several angles of the generally polygonal cross-section, these profiles serving as a mounting bracket for the plates made of a neutron-absorbing material; and a structure for maintaining the profiles therebetween.

Storage rack for fresh or spent nuclear fuel assemblies

The invention relates to a storage device () for the storing and/or transporting of nuclear fuel assemblies, including a plurality of adjacent housings each having a lateral wall and being able to receive a nuclear fuel assembly, the lateral walls being realized at least in part using stacking and intercrossing slotted structural assemblies (), each structural assembly including at least one plate () realized in a first material comprising aluminum. According to the invention, each structural assembly () further includes a tubular cross-section element () inside of which is located said at least one plate (), this tubular cross-section element () being realized in a second material selected from steels and titanium and alloys thereof.
