| Popis: | Hydrogen redistribution and ingress were found to occur between metals proposed for manufacturing containers to store used nuclear fuel in deep geologic repositories. Zircaloy fuel cladding was found to getter hydrogen from steel, and through steel and copper, presumably after disappearance of metal-oxide barriers to hydrogen transport in anoxic conditions expected in-service. Long-term implications for changes in fracture toughness and delayed hydride cracking of the fuel cladding are discussed. |
