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 Product Description popup.authors Зіміна Галина Петрівна Зацарна Олександра Вікторівна Ревка Володимир Миколайович Сорока Світлана Леонідівна popup.nrat_date 2020-04-02 Close
