Abstract

The disposal of radioactive wastes in a geologic repository is considered as the optimum solution. Elemental leaching rates from a simulated nuclear waste glass undergoing gamma irradiation in deaerated deionized water were evaluated as a function of temperature and gamma dose rate. Deaeration of the water eliminated nitric acid formation via air radiolysis, previously shown to substantially accelerate waste glass corrosion, and thus allowed the effects of water radiolysis alone to be measured. Water radiolysis resulted in enhanced reaction-layer thickness on glass samples.
