Preliminary results indicate that the environment expected in a repository in basalt is not highly corrosive to the materials tested. Comparisons of weight change data between two simulated basalt groundwater compositions indicate that variations in oxygen fugacity had a minor effect on corrosion of nickel, titanium, and zirconium alloys. The corrosion of cupronickel alloy, however, was drastically reduced when a lower oxygen fugacity was maintained. Effectiveness of a hydrogen/argon sparge to maintain a low oxygen fugacity in a simulated groundwater was demonstrated. 5 tables.
