As part of the Nuclear Regulatory Commission's preparation to assess the Department of Energy's application to construct geologic repositories for high-level radioactive waste disposal, Battelle's Columbus Laboratories is investigating the long-term performance of materials used for high-level waste packages. Data were obtained this quarter on waste glass leaching/dissolution, and efforts to obtain other waste forms continue. A bonding structure has been proposed for the incorporation of B/sub 2/O/sub 3/ into silicate glass. Studies of internal canister corrosion indicate that zinc may affect the attack of stainless steel exposed to waste glass at elevated temperatures. Groundwater corrosion studies of titanium were completed during this quarter. Data on corrosion of steel in basalt groundwater were obtained. Hydrogen embrittlement tests on annealed material have been performed. Evaluations of prototypical hydrogen fugacities are under way. An experimental verification of the refined general-corrosion correlation is proposed, and calculations on groundwater radiolysis and gamma transport/energy deposition are under way. The description of water chemistry has been expanded. Internal corrosion and leaching experiments have been modified in the accelerated test planning/statistics task. This report documents investigations performed during July-September, 1983. 36 references, 28 figures, 23 tables.
