Flow Accelerated Corrosion (FAC) is thought to be the origin of the pipe thinning in the pipe of second cooling system of power plants. FAC is a phenomenon that inclined to and promoted the c orrosion because of the increase of the complex turbulent flow behind the orifice. Now the analysis of the mechanism of FAC for maintenance of the nuclear reactor is performed. Although the r ough surface is confirmed over the pipe wall, influence of the shape on the corrosion is not understood at this stage. Therefor...
