Research and Surveillance Activities for the Improvement of Pipe Wall Thinning Management

(1. Discussion on Management Rule Revision Assuming Prediction Method Implementation)

Abstract

In JSME, research committee for the improvement of pipe wall thinning management had been held for 6 years in three phases since FY2008. In this committee, research and surveillance have been conducted on concerned technical area. Succeedingly, the 4th phase started from FY2015 and under this committee, new working group called “Management Rule Revision WG” was set up to review practical application and standardization of the developed relevant technique, especially prediction method. In this WG, implementation of prediction method to the management rule is mainly being discussed. So far in its activities, concept of adding new “Chapter D” providing option of utilizing prediction method to PWR/BWR technical rule has been proposed.
