Аннотация
© 2020 Elsevier B.V.This paper presents the first comparative experimental assessment of the microstructures of the same surveillance specimens of VVER-1000 high Ni weld: after the primary irradiation, recovery annealing and re-irradiation in the same industrial NPP (Balakovo NPP unit 1) to assess the possibility of its lifetime extension after annealing up to 60 years. Therein, studies of both the initial (carbides) and radiation-induced hardening phases (precipitates and dislocation loops), and the behavior of grain boundary segregation as well are presented. It has been shown that the microstructures of high Ni VVER-1000 weld after the primary irradiation and re-irradiation after recovery annealing up to the close values of fast neutron fluences are identical: the characteristics of both initial and radiation-induced hardening phases, as well as grain boundary segregation, are the same.
