Complex studies of the base metal and heterogeneous weld №23 of the SUZ pipe and the cover of the ARC of the upper unit of the WWER-440 reactor of the Rivne NPP power unit метою1 to study the effect of deformation accumulation from static and low-cycle loads on possible degradation of mechanical properties to solid properties toughness, crack resistance characteristics and structure of steels and their welded joints. A methodology for dismantling the metal structures of the upper unit of the WWER-440 reactor from the effects of dynamic influences has been developed, computer models have been created in the ABAQUS software package and structural strength calculations under static, cyclic and seismic loads of the upper WWER-440 reactor have been performed. The established criteria for determining the technical condition of heterogeneous welded joints could be used to ensure reliable operation and environmental safety of potentially dangerous production facilities that have exhausted their planned resource, which are responsible welded metal structures, including metal structures and pipelines SUZ pipes, covers ARC upper WWER-440 reactor unit.
