Abstract
An arrangement for the storage of nuclear reactor fuel assemblies having a section wherein fuel is present and a section wherein fuel is not present. The fuel assemblies are placed in a plurality of elongated cells which are joined together to form a cellular structure. The fuel assemblies are placed within the cells at different elevations so that the fuel containing section of one fuel assembly is next to the non-fuel-containing sections of each fuel assembly surrounding the first fuel assembly. The vertical staggering of the fuel containing sections achieves space reductions while maintaining the stored fuel in a subcritical assemblage.
Claims12
A storage arrangement for elongated nuclear reactor fuel assemblies, each of said elongated fuel assemblies having an active section along its longitudinal axis wherein fuel is located and an inactive section along its longitudinal axis wherein fuel is absent, said storage arrangement comprising:
- an elongated, cellular structure comprised of a plurality of elongated cells positioned radially adjacent to each other, each of said cells being adapted to receive one of said fuel assemblies, said fuel assemblies being positioned within said cells;
- and
- means for spacing said fuel assemblies within said structure along the longitudinal axis of said cells, said means for spacing said fuel assemblies positioning said fuel assemblies at predetermined locations along said longitudinal axis such that said active section of each fuel assembly is located adjacent to said inactive section of each fuel assembly radially adjacent to it.
