Abstract
A radioactive fuel cell storage rack is comprised of structural elements including elements which are hollow and cruciform in section. Each leg of the cruciform structural element includes a neutron shield therein. The free end of the legs of the cruciform structural element converge so as to have an included angle of approximately 90.degree.. The rack is comprised of such cruciform elements as well as cooperating elements which are generally T and L shaped in section.

A structural element for defining walls of cells in a radioactive fuel storage rack comprising a hollow metal element which is cruciform in section so as to have four legs of uniform length, said element being defined by a plurality of sheet metal members welded together and defining a hollow interior space of cruciform shape which extends into said legs, each leg of said element being adapted to be a dividing wall between two adjacent cells, a neutron absorbing shield of cruciform shape, said shield filling said hollow interior, each end of each leg being configured to mate with a leg on a mating structural element which is adapted to define at least one wall of a cell.
A fuel cell storage rack comprised of three different types of structural elements, the first structural element being cruciform in section and defining a wall of four cells, the second element being T-shaped in section and defining a wall of two cells, the third element being L-shaped in section, each element being hollow and having a neutron shield therewithin, each leg of each element being of uniform length, the number of said first elements exceeding the number of said second elements, the number of said second and third elements being sufficient to provide the desired outline of the periphery of the rack.
A fuel cell storage rack comprised of a plurality of different types of structural elements, the first structural element being cruciform in section so that each leg thereof defines a wall of four adjacent cells, the second element being T-shaped in section so as to define a wall of two adjacent cells, each element being hollow and having a neutron shield within each leg, each leg of each element being of uniform length, the number of said first elements exceeding the number of said second elements, each leg of each element terminating at a free end thereof in converging surfaces whose included angle is approximately 90.degree..
