Periodic safety review for Wolsong Unit 1

This paper is an extract from the 2004 Annual Report of the Korea Institute of Nuclear Safety on the first Periodic Safety Review of the Wolsong 1 unit. The PSR review results are possible to be utilized in verifying the safety for plant life extension. Korea has performed the research on how to link the PSR with continued operation. According to the present results of the research, there seems to be no significant technical safety issues on utilizing the PSR results for life extension. However, additional requirements should be assigned for regulatory position for continued operation such as review of aging management, impact on environment, updated technical specifications, and supplemented FSAR.
