Abstract
A rack for storing spent radioactive fuel is disclosed in which a set of cells, consisting of self-supporting metal tubes arranged in a staggered fashion with respect to each other, and joined to each other along their longitudinal edges, forms a rigid spatial structure. The tubular hole defined by each of four tubes has a larger cross-sectional area than said tubes and is provided with neutron-absorbing material. This material is independent of the tubes and may be removed and re-inserted in the tubular hole as often as necessary. Various tubular structures are also disclosed.

A rack for storing spent radioactive fuel, of the type including a series of parallel cells with a protection consisting of neutron-absorbing material such as boron, which cells are attached to a base plate or structure, the assembly of cells being comprised of a plurality of self-supporting metal tubes arranged in a staggered fashion;
- the tubular hole delimited by each such four tubes having a larger cross-sectional area than that of each tube;
- the said tubular holes of larger cross-sectional area being intended to receive the protection of neutron-absorbing material;
- and said protection being independent of said tubes in order to permit its removal and later insertion into said holes.
