Abstract

A model has been developed to predict the stress corrosion cracking behaviour (SCC) of used-fuel copper containers in a deep geologic repository. By comparison of the predicted evolution of the environment with criteria for the SCC of pure copper, it is concluded that copper containers in a deep geologic repository will not be susceptible to SCC. In particular, the requirement for the simultaneous presence of a thermodynamically stable Cu2O/CuO surface film and a significant concentration of SCC agents is not satisfied at any time during the 106 year simulation period.
