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.
