Regulatory Aspect of Aging Managementfor Periodic Safety Review in Korea

摘要

In less than 10 years, the first commercial Pressurized Water Reactor (PWR) plant in Korea will reach its officialdesign life. As part of safety activities, developed countries have already implemented periodic safety review (PSR) orequivalent programs to check and improve the safety of operating nuclear power plants (NPP) during their plant life. At theend of 1999, it is decided by Korean Atomic Energy Safety Committee to adopt the PSR program to apply to Koreanoperating 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 nuclearplant. This paper is intended to introduce the regulatory aspect and strategy of Korean PSR and especially of agingmanagement. The background and scope of basic PSR guidelines are described, and a summary of technical criteria foraging management, which shows a regulatory direction for PSR, are also presented.
