FLOW ACCELERATED CORROSION AND AGING MANAGEMENT IN NUCLEAR POWER PLANTS
-
-
Abstract
Flow Accelerated Corrosion (FAC) 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.
