The probabilistic fracture mechanics analysis code PASCAL2 has been updated by Japan Atomic Energy Agency (JAEA) to support the validation of the codes and standards that provide the structural integrity assessment method of reactor pressure vessels during pressurized thermal shock. In this study, the evaluation methods for flaw initiation considering weld-overlay cladding and nondestructive inspection models and considering the existence of cladding have been improved. Using the improved PASCAL2 code, the effects of flaw initiation, the growth model for a cladding flaw, and the nondestructive inspection model on failure probability have been analyzed. The analysis verifies that the application of the improved flaw initiation model decreases the conditional probability of failure. The result also shows that only the maximum detection probability affects the failure probability among the parameters of the improved nondestructive inspection model.<br>
