Factors controlling the irradiation embrittlement response of low alloy pressure vessel steels
Description
288 deg C-neutron irradiation embrittlement in A533B/A508-type PWR pressure vessel steels is reviewed and rationalised in terms of elevated temperature radiation damage structures, interactive solute element effects, and precipitation mechanisms. The effects of composition, neutron dose, dose rate, spectrum and irradiation temperature are documented and related to these basic processes. Enhanced radiation embrittlement is primarily caused by the presence of copper in solution at levels exceeding approx. 0.1%, and is augmented by high nickel levels. Severe irradiation embrittlement problems in new PWR plant are circumvented by the specification and routine availability of advanced plate and forging grades with very low residual impurity levels.
