In less than 10 years, the first commercial Pressurized Water Reactor (PWR) plant in Korea will reach its official design life.As part of safety activities, developed countries have already implemented periodic safety review (PSR) or equivalent programs to check and improve the safety of operating nuclear power plants (NPP) during their plant life.At the end of 1999, it is decided by Korean Atomic Energy Safety Committee to adopt the PSR program to apply to Korean operating NPP.Recently, Kori unit 1 has started the review for the first tentative application of PSR as a model case.Management of aging is one of the major factors to be considered in periodic safety review or life extension of a nuclear plant.This paper is intended to introduce the regulatory aspect and strategy of Korean PSR and especially of aging management.The background and scope of basic PSR guidelines are described, and a summary of technical criteria for aging management, which shows a regulatory direction for PSR, are also presented.
