Information × Registration Number 0213U004236, 0112U001621 , R & D reports Title Prediction of radiation life time of WWER accounting for the effects of irradiation hardening and softening popup.stage_title Head Sergiy Kotrechko, Registration Date 17-10-2013 Organization Institute for metal physics NAS Ukkraine popup.description2 Regularities of change in the characteristics of irradiation hardening for both base metal and weld metal over a wide range of concentrations of alloying elements are ascertained. Two models of the evolution of precipitates in thermal annealing and irradiation are developed and tested. For WWER-1000 RPV metal, a technique for prediction of maximum allowable fluence value is developed; the latter is defined as the fluence, at which the magnitude of the strength of the irradiated metal reaches a critical level. This level is determined accounting for both the parameters of the crack in the wall of the reactor pressure vessel and the loading value at emergency (pressurized thermal shock).
