Chloride-induced stress corrosion cracking of used nuclear fuel welded stainless steel canisters: A review

It has been shown the salt deposition conditions in coastal areas result in chloride-induced stress corrosion cracking (CISCC) on the stainless steels used to contain nuclear fuel. The present study conducts a critical review of the realistic environmental conditions in-service canisters are subjected to, including the presence of surface temperature variables, surface relative humidity, surface deposits and tensile stresses that are caused by welding processes. The CISCC related experimental results of the canister materials are also reviewed to evaluate the potential occurrence of CISCC.
