Journal ArticleDOI
Assessment of relative contributions from different mechanisms to radiation embrittlement of reactor pressure vessel steels
TL;DR: In this paper, the authors analyzed the relative contributions from the following mechanisms: radiation-induced hardening, inter- and intragranular segregation of impurities at precipitate/matrix interfaces.
Journal ArticleDOI
The contribution of grain boundary effects to low-alloy steel irradiation embrittlement
TL;DR: The contribution of irradiation-induced enrichment of grain boundaries by impurities to irradiation embrittlement of reactor pressure vessel materials is discussed in this paper, where possible mechanisms of impurities and the effect of alloying elements are considered.
Journal ArticleDOI
Radiation embrittlement of low-alloy steels
TL;DR: In this paper, the results of Russian VVER-440 and VVER1000 surveillance programs and results of research programs on reactor pressure vessel (RPV) steel irradiation in surveillance channels of power reactors are discussed.
Journal ArticleDOI
Radiation embrittlement and thermal annealing behavior of CrNiMo reactor pressure vessel materials
TL;DR: In this article, the effects of low-alloyed chromium-nickel-molybdenum steel on the impact transition temperature of the last generation of Russian type of reactor vessels (WWER-1000) are investigated.
Journal ArticleDOI
Microstructural behavior of VVER-440 reactor pressure vessel steels under irradiation to neutron fluences beyond the design operation period
TL;DR: In this article, electron microscopy and fractographic studies of the surveillance specimens from base and weld metals of VVER-440/213 reactor pressure vessel (RPV) in the original state and after irradiations to different fast neutron fluences from ∼5.5 MeV up to over design values have been carried out.
