The document presents new computational analysis results for the SSS and fracture strength of the PGV-1000M steam generator welded joint obtained with overall consideration of such factors as the spatial character of the SSS, residual manufacturing stresses and strains after welding and heat treatment, elasto-plastic deformation of the metal and loading history, computational schematization of defects with consideration of surface defects of corrosion origin.The developed procedure for calculating the SSS and fracture strength of welded joints was used for justifying the extension of life for PGV-1000M steam generators of power unit 3 at the Rivne NPP.
