As part of the information needed by the Nuclear Regulatory Commission to assess the Department of Energy's application to construct geologic repositories for high-level radioactive waste, Battelle's Columbus Division is investigating the long-term performance of materials used for high-level waste packages. Waste-form studies are being directed toward investigating spent-fuel leaching/dissolution behavior. Glass crystallinity data were derived in preparation for a devitrification/glass-leaching experiment. Glass-dissolution-rate data were collected which verified the Battelle dissolution model, and data from an organic-acid leach experiment were analyzed. The reactions of groundwater species with steels are being studied to evaluate susceptibility to pitting and stress-corrosion cracking. Potential cracking agents are being investigated by slow strain rate experiments. The general-corrosion model was further developed, based on known principles of mass transport and radiolytic production. Spent fuels are being used in integral tests with flowing simulated groundwater to study the role of cladding in radionuclide release and certain combined-effects processes. The water-chemistry model was expanded to include uranium species, and interactions between iron and chloride species and water-radiolysis species were examined.
