Abstract
We analyze the results of investigations of the in-service defects of heat-exchange tubes of steam generators of WWER reactors and the metal of pipelines and welded joints. The specific features of damage to heat exchangers and welded joints of the collectors with branch pipes of the bodies steam generators are analyzed. The causes of degradation of materials of the secondary coolant circuit are established. The directions of subsequent investigations aimed at increasing the reliability and duration of service life are outlined.
