PbSCC of Ni-base alloys is active over a wide range of environmental conditions but for the higher Cr content Alloys 800 and 690 only under abnormal crevice environment of high or low pH that can occur in the secondary side of Pressurized Water Nuclear Reactors (PWRs). Several experimental campaigns have aimed at understanding this phenomenon, concluding that PbSCC can develop in both acidic and caustic solutions, for low and high concentration of Pb, across a wide electrochemical potential range and in presence of chlorides contaminants.
