The Nuclear Regulatory Commission is responsible for the licensing of deep-mined geologic repositories for high-level radioactive waste disposal. The NRC's Office of Nuclear Regulatory Research is developing the technical capability to assess the Department of Energy's compliance with applicable regulations. As part of the NRC's effort, Battelle's Columbus Laboratories is investigating the long-term performance of materials used for high-level waste packages. The experimental program for investigating waste form degradation is in preparation, and the mathematical description of waste glass dissolution has been refined. Groundwater corrosion studies have been nearly completed for titanium and are under way for steel container materials. Internal glass-stainless steel corrosion tests have been initiated and pitting chemical interactions are being evaluated. A first-cut physical description of general corrosion of container materials in contact with groundwaters is near completion. An improved description of fluid flow through a nuclear waste package was developed, along with a comprehensive method for tracking release of specific radioisotopes. Efforts continue in water-chemistry studies, accelerated testing, and procedure development. This report documents investigations performed during April-June, 1983. 7 references.
