Abstract
The fatigue life of austenitic stainless steel in LWR water environment tends to reduce remarkably with decreasing strain rate and increasing temperature. In this study, based on fatigue tested data conducted in simulated LWR water environments, the effects of these parameters on fatigue life reduction have been examined quantitatively, and a method to estimate the fatigue life correction factor F_<en> in BWR and PWR water environment respectively has been proposed for austenitic stainless steels. The research was carried out by the Japan Power Engineering and Inspection Corporation (JAPEIC) which was entrusted by the Ministry of Economy, Trade and Industry (METI).
