Abstract
The analysis of operational damages of heat transfer tubes (HTT) in steam generators (SG) of WWER-1000 power units was carried out. The processes of contamination of the surfaces of HTT of SG PGV-1000M are considered. The processes of formation and growth of corrosion pits on the surface of heat transfer tubes are analyzed. The process for the initiation of corrosion pits and the development of cracks in the heat transfer tubes metal, which includes the combined action of a corrosive environment and non-metallic inclusions in heat transfer tubes, was proposed.
