Conducted evaluation of technical state of welded joints, welding the collectors of the primary loop to the body of the sample of steam generator PGV 1000, located in Resource center National Research Nuclear University MEPhI at "AEM-Technologies" Atommash factory in Volgodonsk. The results of point-by-point scan shows that SLS 1000 µv and above, for almost all samples detected multiple superficial imperfections caused by the presence of certain rust spots and traces of a deep spot corrosion, and the presence of small nicks, scratches and other imperfections.
