A number of piping components in the secondary system of nuclear power plants (NPPs) are exposed toaging mechanisms, such as flow-accelerated corrosion (FAC), cavitation, flashing, solid particle erosion,and liquid droplet impingement erosion. Those mechanisms may lead to thinning, leaking, or rupture ofthe components. Due to the pipe ruptures caused by wall thinning in Surry unit 2 in the USA in 1986and Mihama unit 3 in Japan in 1994, pipe wall thinning management has emerged as one of the mostimportant issues in the nuclear industry. To manage pipe wall thinning, a foreign program has been utilizedfor NPPs in Korea since 1996. As our experience and knowledge of pipe wall thinning management haveaccumulated, our program needs to reflect our experience, requests from users, and the result of recentexperiments using Flow Accelerated Corrosion Testing System (FACTS). FACTS is the empirical experimentalfacility developed by Korea Atomic Energy Research Institute (KAERI) for tests. Accordingly, KEPCO-E&Cdeveloped a 3D-based pipe wall thinning management program called ToSPACE in 2016. This paper describesa comparison between the FAC analysis results using ToSPACE and the experimental results using FACTSto verify their applicability to pipe wall thinning management in NPPs.
