Abstract

The effect of sulfate ion which is one component of seawater or concrete on the corrosion behavior of SUS316L was investigated in high active liquid waste tank environment. The corrosion tests were conducted using surrogate high active liquid waste containing some oxidizing metallic ions and nitric acid. The results showed that sulfate ion decreased the corrosion rates. The XPS analysis indicated that the compound formed from sulfate ion on material surfaces suppressed the anodic reaction.
