Corrosion and Protection of Anchor Bolts for Stainless Steel Containers in Nuclear Power Plants

The corrosion failure cases of anchor bolts for stainless steel containers in nuclear power plants were analyzed. The results showed that galvanic corrosion, crevice corrosion and stress corrosion were the main causes of the failure. According to the anti-corrosion design requirements, protection measures for nuclear power plant construction stage were proposed.
