A good correlation of data obtained by two magnetic methods is proved. Reliability of magnetic methods was confirmed by ultra sound and radiographic study of metal. Tendency to the increase of NDS of metal of welded joints N 111 of all studied steam generators was observed. Recommendations about joint use of magnetic methods are presented, which may presents objective and full information about the real state of the base metal and of welded joints of pipe-lines of power units of NPS. It is recommended to perform the monitoring by magnetic methods of the metal of equipment and pipe-lines of power units of NPS during their lengthy operation. Data base of " Catalog of data of non-destructive control of stressed-deformed state of vessel of reactors of the type WWER-1000 and pipe-lines of NPS" was supplied with data obtained in 2013. Data base of annual eddy-current control of pipe still of steam generators of power units of SU NPS was expanded, its statistical treatment was carried out.
