The corrosion behavior of FeCrAl-ODS steels for the accident tolerant fuel cladding of LWRs was investigated in nitric acid solution for the reprocessing process of spent fuels. The immersion tests and the electrochemical tests were carried out under gamma ray irradiation. The corrosion of fuel cladding of FeCrAl-ODS steels dose not affected the reprocessing process.
