FY23 Status Report: SNF Interim Storage Canister Corrosion and Surface Environment Investigations

Bryan, Charles R.; Knight, Andrew W.; Katona, Ryan M.; Smith, Elizabeth; Schaller, Rebecca S.

Work evaluating spent nuclear fuel (SNF) dry storage canister surface environments and canister corrosion progressed significantly in FY23, with the goal of developing a scientific understanding of the processes controlling initiation and growth of stress corrosion cracking (SCC) cracks in stainless steel canisters in relevant storage environments. The results of the work performed at Sandia National Laboratories (SNL) will guide future work and will contribute to the development of better tools for predicting potential canister penetration by SCC.
