Abstract

Based on the nuclear safety review on the defect beyond tolerance of Unit 2 reactor pressure vessel of Tianwan NPP and Unit 4 reactor pressure vessel of Qinshan Phase II NPP, to the standards for the safety evaluation of the fracture mechanics of RPV defects beyond tolerance, the defect characterization, the fracture toughness, the selection of residual stress and the thermal shock under load are discussed, in order to be useful for the follow-up of the nuclear safety review.
