Post-irradiation annealing effects on the thermal sensitization and IASCC recovery for highly irradiated types 304 and 316L stainless steels were investigated using EPR and SSR tests. Irradiated type 316L stainless... Keywords: stainless steel, irradiation-assisted stress corrosion (IASCC), post-irradiation annealing, thermal sensitization, EPR tests, IGSCC, light water reactor
