Prediction of irradiation embrittlement of vanadium alloyed low nickel steel for future reactors
Source abstract
Abstract
Abstract A comparison between pearlitic 2CrMoV steel (WWER-440) and 9% Cr based ferritic–martensitic steels (EUROFER 97 and LA12TaLC) is presented as regards irradiation induced ductile–brittle transition temperature shifts. For neutron doses of 1.5–2 dpa and irradiation temperatures around 300 °C the transition temperature shifts for WWER-440 steel and EUROFER 97 welds are comparable. In the temperature range 350–500 °C the radiation embrittlement levels of both steels are low. Moreover, post-irradiation annealing is proposed as a promising method to predict results of high temperature irradiation embrittlement from existing lower temperature irradiation embrittlement data.
