High density spent fuel storage rack
A high density spent fuel storage rack including a plurality of neutron absorbing containers are described. The containers are designed to perimentrically encircle a fuel assembly, and are arranged so that the rack can store a plurality of fuel assemblies disposed vertically in an array with predetermined spaces between the adjacent fuel assemblies. Each of the containers is provided with enlarged upper and lower end portions respectively abutting against enlarged upper and lower end portions of the adjacent containers along their outer peripheries. The abutting end portions are joined by edge-welding to one another whereby the containers are formed into a unitary structure providing predetermined spaces between the adjacent containers.
