For evaluation of PWSCC crack extension behavior detailed residual stress evaluation such a stress distribution on the evaluation points’ thickness is needed. In order to establish the residual stress evaluation procedure, Japan Nuclear Energy Safety Organization (JNES) had a seven years’ project from 2001 to 2007. In this project several sensitivity analyses were performed for understanding key points for the numerical simulation of residual stress. And also residual stress measurements were carried out for validation of the simulation methods. In this paper focused on the safe end nozzles, the results of the sensitivity analyses and the measurement result of the residual stress of the U-groove weld joint were introduced. Based on these result, the key issues of a guideline of a standard residual stress analysis procedure was proposed.
