This paper presents the results of an experimental programme that was carried out to investigate the possible effects of radiation on the anaerobic corrosion of the carbon steel overpack that will surround high-level waste and spent fuel containers in the Belgian Supercontainer concept. The anaerobic corrosion rates of carbon steel were measured by monitoring hydrogen evolution rates using a manometric gas cell technique. The parameters that were investigated in the experimental programme were: temperature (25 and 80°C), chloride concentration (0 and 100 mg/L) and gamma irradiation dose rate ( 0 and 25 Gy/hr). Radiation at a dose rate of 25 Gy/hr seemed to have a negligible effect on gas generation rates compared to the unirradiated situation.
