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 to 2 dpa and irradiation temperatures around 300 ºC the transition temperature shifts for WWER-440 steel and Eurofer 97 welds are comparable. In the temperature range 350 to 500 ºC 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.
