F082001 Recent Advance in Study on FAC

Abstract

Flow accelerated corrosion (FAC) is an important issue for aging fossil and nuclear power plants. FAC causes thinning of pipe walls which occasionally leads to a piping rupture accident. "Research Committee on Improvement and Practical Use of Pipe-Wall-Thinning Management" of JSME revised technical knowledge regarding pipe wall thinning phenomena attached to JSME "Code for Power Generation Facilities -Rule on Pipe Wall Thinning Management-JSME-S CA1 2005." This paper summarizes the technical knowledge of recent advances in study on FAC.
