popup.description2

Maximum strength levels for base metal and weld metal of WWER-1000 are found, at exceeding of which due to irradiation hardening, disintegration of the pressure vessel may occur under the conditions of emergency loading at PTS. Regularities of change in brittle strength level of RPV metal depending on fluence are ascertained. The findings obtained enable both to realize a rapid assessment of current state of NPP power units and to predict their radiation life-time.5481
