概要
As a part of the aging structural integrity research for LWR components, the probabilistic fracture mechanics (PFM) analysis code PASCAL has been developed in JAEA. This code evaluates the conditional probabilities of crack initiation and fracture of a reactor pressure vessel (RPV) under transient conditions such as pressurized thermal shock (PTS). A case study on the effect of non-destructive examination performance was performed using PASCAL. The analysis results showed that one non-destr uctive examination with good performance had a more significant effect on the probability of failure than non-destructive examinations repeated with low performance.
