Evaluation of the residual stresses in the welded joint of the header with a connecting pipe of a steam generator after additional thermomechanical treatment
Stepanov, G.V.; Kharchenko, V.V.; Babutskyi, Anatolii; Trunov, N.B.; Piminov, V.A. (2010)We present the results of numerical evaluation of the possibility of application of additional thermomechanical treatment to the welded joints of the headers with connecting pipes of PGV-1000 steam generators from WWER-1000 ... -
Redistribution of stresses in the header-PGV-1000 steam generator connector weldment under loading after thermal treatment
Kharchenko, V.V.; Stepanov, G.V.; Kravchenko, V.I.; Kobel'skii, S.V.; Babutskyi, Anatolii; Trunov , N.B.; Piminov, V.A. (2009)Additional heating of a thickened portion of the steam generator connector during postrepair thermal treatment of the header-connector weldment leads to a decrease in residual tensile stress levels. It is shown that during ...
