摘要

This paper describes recent results from an investigation of the effects of γ-radiation on the anaerobic corrosion of carbon steel in cement, in relation to the Belgian Supercontainer Concept for radioactive waste disposal. Anaerobic corrosion rates were measured by monitoring hydrogen evolution and the corresponding electrochemical behaviour was investigated by measuring open circuit potential and linear polarisation resistance. The test medium was alkaline simulated porewater, at γ-irradiation dose rates of 0 and 25?Gy?hr?1, temperatures of 25?°C and 80?°C and chloride concentrations of 0 and 100?mg/l. The effects of radiation on the corrosion behaviour were found to be small.
