ABSTRACT:
A storage system for the storage of nuclear waste material is disclosed. A storage system includes a plurality of storage canisters of dimensions allowing it to hold spent nuclear fuel rods and a rack structure for maintaining the storage canisters in a definite horizontal and vertical array. A storage system is of particular value for use in underwater nuclear waste storage areas. When used underwater, the system includes buoyant chamber positioned above the rack structure and flexibly connected thereto to provide an upper force to reduce the downward load exerted on a floor of the water pool by the storage canisters and the rack structure. The system thereby allows a far greater number of fuel rods to be stored in an underwater nuclear waste storage area than was possible in the past.
