Information × Registration Number 0220U000323, 0116U006287 , R & D reports Title Development of the generalized procedure and recommended practice for performing the calculated analysis of the stress-strain state and fracture resistance to substantiate the strength and extension of lifetime of RPVs as well as NPP with WWER primary circuit equipment elements using the current methods of consideration of deficiency and deformation history of thermomechanical loading popup.stage_title Head Kharchenko Valeriy V., Доктор технічних наук Registration Date 29-01-2020 Organization Institute for problems of strength NASci of Ukraine popup.description2 The authors present the first edition of the methodological recommendations on the defined calculation of the stress-strain state (SSS) and fracture resistance of the reactor pressure vessel and equipment elements of the first NPP circuit with WWER, in particular, weldment of the heat header to the steam generator PGV-1000M and elements of internal vessel devices (compartment) considering deficiency. The methodical recommendations consider the main tenets of modern regulatory documents adopted in the Ukrainian nuclear industry and are based on the application of state-of-the-art models and methods of solutions to the non-isothermal thermal elastoplasticity boundary tasks and problems of fracture mechanics. The project proceedings will be formulated upon their completion in 2020 as the standard prepared by the Ukrainian institution on Methodical Recommendations on the Calculation of the Stress State and Fracture Resistance of Reactor Pressure Vessels and the First Circuit Equipment Elements of NPP with WWER.
