ABSTRACT:
Storage rack for elongated nuclear reactor-fuel assemblies having a polygonal cross section including an array of elongated sheetmetal shells of corresponding polygonal cross sections for receiving respective fuel assemblies therein at locations of the rack at which the fuel assemblies are to be positioned, the shells being spaced from one another and neutron-absorbing material of given thickness being disposed in the space therebetween, mutually adjacent shells of the array being connected to one another by a weld at respective upper edges thereof, the space between the shells being greater than the given thickness of the neutron-absorbing material and being bridged at the weld connection, for the most part, by sheetmetal extending transversely to the longitudinal direction of the shells, and means defining inlet openings to the spaces between the shells for providing access to the spaces of medium for cooling the fuel assemblies.
