<p>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.</p> |
