| Abstract Scope |
Management of spent nuclear fuel (SNF) is a world-wide emerging issue to determine sustainability of nuclear energy. So far, most SNF is stored in interim storage system such as wet pool and dry cask storage system (DCSS). In particular, installation of DCSS is coming into the spotlight for long-term massive storage of light water reactor SNF due to the limited capacity of wet pools. However, the stainless steel canister of DCSS is susceptible to chlorine-induced stress corrosion cracking (CISCC) which is a potential concern for long-term storage. In this study, cold spray depositions of AISI 304L, 316L, pure Ti and nitronic 60 are conducted on sensitized AISI 304 plates as surrogate storage canister. Electrochemical corrosion tests and microstructural characterization of the specimens are performed to evaluate the CISCC resistance. |
