Summary

The durability of Savannah River Plant (SRP) waste forms was assessed for glass containing up to 32 wt% simulated waste oxides. Leach tests included standard MCC-1 static tests and PCT experiments. Leachate solution analysis combined with bulk and surface studies were performed to study low-level waste- glass corrosion as a function of waste loading. Results of this study showed that the durability of the SRP low-level waste glass decreased as waste loading was increased, due to the presence of alkali in the waste. The formation of surface layers may have acted as a barrier to corrosion in glasses of lower waste loading.
