Since lead may be one of the potential contributing causes of intergranular corrosion/stress corrosion cracking, which is found in alloy 600 (UNS N06600) steam generator tubing in PWR secondary systems, the effect of lead on the tubing’s thin film was investigated in this study. It was demonstrated that the presence of lead in the oxide thin film enhanced the selective dissolution of nickel from alloy 600 base metal.
