Abstract: A container is designed to safely store radioactive debris from, for example, a nuclear reactor meltdown, in water or air. The container, with preferably although not necessarily all metal parts, has an overpack having an elongated cylindrical body extending between a top end and a bottom end, a planar bottom part at the bottom end, an open top at the top end, and a circular planar lid mounted over the open top. A basket is situated inside of the overpack. The basket has a plurality of elongated cylindrical canisters that are in parallel along their lengths. Each of the canisters has an elongated cylindrical body extending between a top end and a bottom end, a planar bottom part at the bottom end, an open top at the top end, and a circular planar lid mounted over the open top.

Abstract: In one embodiment, a system and method for dry storage comprises removing spent fuel rods from their fuel rod assemblies and placing the freed fuel rods in a storage cell of a dry storage canister with a high packing density and without a neutron absorber material present. Nuclear fuel assemblies for powering nuclear reactors generally comprise large numbers of fuel rods that are contained in discrete fuel rod assemblies.

Abstract: Disclosed are apparatus and methods for storing or transporting spent nuclear fuel. In one embodiment, a container (10) for storing spent nuclear fuel comprises a plurality of elongated tubes (2, 4, 6, 7) that receives spent nuclear fuel rods. Each tube (2, 4, 6, 7) has four sidewalls and four corners defining a rectangular cross section. The plurality of tubes (2, 4, 6, 7) is arranged in an alternating pattern. An attachment means attaches together the plurality of tubes (2, 4, 6, 7) at the corners so that two adjacent sidewalls (64, 66, 68, 70) of adjacent tubes (2, 4, 6, 7) are substantially aligned.

Abstract: Systems and methods of loading and/or removing spent nuclear fuel from a spent nuclear fuel pool are disclosed. A spent fuel basket compatible with a dry storage and/or transport system is disposed in a spent nuclear fuel pool. At least one spent fuel assembly is loaded in one of a plurality of chambers associated with the spent fuel basket. The spent fuel basket is inserted into a spent fuel canister. The spent fuel canister is loaded into a transfer cask. The spent fuel canister is then transferred from the transfer cask to a storage cask or a transport cask, which can be sealed and stored on-site or in an off-site storage facility.

Abstract: A containment cask for safely transporting and storing radioactive hazardous waste in a dry air environment. The cask comprises a single drum containing the radioactive hazardous waste, a sealed and shielded containment vessel containing the drum, and an outer container. The outer container can be in the form of an outer shield vessel (OSV) made from iron to provide further shielding. This outer container is appropriate for a drum having higher activity waste. The outer container can also be in the form of an overpack assembly that adds protection for atmospheric hazards, but adds little in terms of shielding. This outer container is appropriate for a drum having lower activity waste.

Abstract: In one aspect, the disclosure relates to storage systems comprising a protective barrier to chemical attack, e.g. to chloride-induced stress corrosion cracking (CISCC). Moreover, the disclosed protective barriers can provide enhanced protection to or otherwise shield against general corrosion. In a further aspect, the disclosed protective barriers have minimal activity as catalysts for galvanic corrosion. The present disclosure further pertains to methods of applying the disclosed protective barriers to the disclosed storage systems. In various aspects, the disclosed storage systems are used for the storage of nuclear material. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Abstract: A storage apparatus is provided for dry storage of radioactive nuclear waste. The storage apparatus comprises a sealed canister containing the radioactive nuclear waste and an outer ventilated metal storage overpack (VMSO). The VMSO has a plurality of vents to enable ambient air flow through the VMSO and around the canister to thereby dissipate heat from the canister. The VMSO has a side wall having an inner metal layer and one or more sets of alternating layers. Each set includes a neutron absorbing layer adjacent to another metal layer so that neutron absorbing and metal layers alternate throughout the side wall.

Abstract: Systems and methods of transferring nuclear fuel from fuel pools having size and/or weight limitations to a storage or transport cask are disclosed. A canister containing spent nuclear fuel is inserted into a transfer cask. A shielding sleeve is then placed around the transfer cask. A lifting device simultaneously lifts the transfer cask and the shielding sleeve over a storage cask and the spent fuel is transferred from the transfer cask to the storage or transport cask.
