In order to improve the accuracy and reliability of failure probability in PFM analyses a PFM code PASCAL for evaluating the Failure probability of an aged reactor pressure vessel has been developed. In this code, a function to evaluate the effect of ductile crack extension, where the increase of fracture resistance by ductile crack extension is taken into account based on R6 method. Three fracture criteria are introduced including ductile crack extension analysis by R6 method category 3 analysis. Using the NRC/EPRI PTS benchmark problem, the influences of fracture criterion are compared. Results of sample analysis suggested that the consideration of ductile crack growth is important in this kind of failure analyses.
