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.

管道流体加速腐蚀是核电厂和常规电厂碳钢或低合金钢材料汽水管道的一个重要的老化机理，历史上曾发生过美国萨里核电站2号机组和日本美滨核电站3号机组管道破裂等导致人员伤亡的严重事故；本文简要总结了核电厂管道流体加速腐蚀的经验教训、机理及其老化管理的一些方法和对策。
