Nearly 40% of all nuclear power plant units have been in operation for > 10 yr, and the aging effects due to erosion/corrosion in the most fundamental of pressure boundary components, the piping, are now recognized as a serious challenge to system operability and plant safety. Since the issuance of I.E. Bulletins 87-01 and 87-36, the industry has had to rapidly initiate or expand programmatic inspections and evaluations for the effects of erosion/corrosion. Sargent and Lundy developed a generic short-term program for Commonwealth Edison Company (CECo) designed to determine whether significant wall thinning due to erosion/corrosion was occurring in single-phase secondary piping systems. As a second step, CECo has established a special program to determine whether single-phase erosion/corrosion is occurring at their 12 operating nuclear stations. Two additional key issues related to the programmatic approach to erosion/corrosion are system design and operation and influences of water chemistry.
