腐蚀

Flow Accelerated Corrosion is an important aging mechanism for water and water/steam piping made of carbon steel or low alloy steel in both nuclear power plants and fossil power plants. Accidents in Surry Unit 2 in USA and Mihama Unit 3 in Japan, caused by pipe rupture due to FAC, led to severe casualties. The experience, mechanism and countermeasures about the aging management of FAC in nuclear power plants are summarized in this paper.
