Report on research: p.. - 32, Fig. - 22, Table. - 0, Source - 3. Object of research: basic metal and welded joints of pipelines and equipment of NPP. Objective: Implementation of works on NPP Ukraine by diagnostic change control properties of the base metal and welded joints for a long operation in support of safety cases and pipelines while working at a designated lifetime and during its continuation. Development of new effective methods of resource metal basic equipment and piping of NPP. Method of research: studies were performed using the method of magnetic memory, speckle interferometry, of course elements. Main results: The method of magnetic memory work performed under the control of the stress-strain state of pipelines SUNPP. Found the most intense place to be further radiographic control. Analyzed the possibility of using digital speckle interferometry to determine the residual stress of the base metal and weld reactor vessel, which are in operation. The changes hartovyh thermal stresses in the piping layouts as a result of magnetic treatment. It is shown that with a magnetic processing in pipelines may change the location of the zone of maximum stress. For the heat exchange tubes and weld number 111 welding pipe DU 1200 to create natural steam reservoirs and corresponding mathematical models of basic components of piping systems. Keywords: NPP, reactor vessel, welds, magnetic memory, deformation, spektl-interferometry, a method indispensable elements, heat exchange tubes, magnetic treatment.
