Environmental Fatigue Evaluation Method for Nuclear Power Plant of “Codes for Nuclear Power Generation Facilities” in the JSME introduced the environmental correction factor for environmental fatigue evaluation of austenitic stainless steels in PWR plant condition in JNES-SS-0701 developed by a Japanese national project for environmental fatigue tests of nuclear power plants. This environmental correction factor was developed conservatively using all austenitic stainless steel data. To develop accurate environmental correction factors, each correction factor for base metal, weld metal and cast stainless steel has been separately developed.
