Abstract

The latest researches on LWR Environment Assisted Fatigue Issues are summarized in this paper.The requirements on EAF analysis for new NPPs of RG 1.207 published by USNRC are also introduced to discuss how to take the consideration of EAF for new NPPs.At the same time,new advice is put forward on incorporating the EAF into the fatigue analysis method of Section III of ASME B&PV Code.
