Abstract
Abstract This work contains fractographic analysis of base metal and weld metal specimens of a VVER-1000 reactor pressure vessel (RPV) in initial state and after neutron irradiation. In this work, two main types of brittle fracture origins were discovered for VVER-1000 RPV materials in different states—non-metallic inclusions and grain or subgrain boundaries, as well as the correlation between the cleavage initiation distance and critical stress-intensity factor KJc values for each type of fracture origin. In this paper, evolution of relative proportion between these two types of origins under neutron irradiation was also studied.
