The results of long term research concerning the determination of irradiation embrittlement dependence on fast neutron flux for WWER-440 reactor pressure vessel steels are presented in this paper. All Charpy specimens were irradiated at high and low fluence rates in similar conditions in surveillance channel positions. It can be seen that there is a significant flux effect in such WWER-440 reactor pressure vessel steels with higher copper content (> 0.13wt %).
