Review of the applicability of Safety Factors to IAEA PSR NS-G-2.10

Since the Ministry of Education, Science and Technology (MEST), the nuclear regulatory body in Korea established an institutional scheme in January 2001, PSR have been conducted at the sixteen NPPs in Korea to evaluate the safety of the NPPs and to determine reasonable and practical modifications that should be made in order to maintain a high level of safety. For the last ten years, regulators and operator have made great efforts for the successful settlement of the PSR. The PSR, based on such great efforts, have significantly contributed to the improvement of the country's NPPs. Under these circumstances, there is a movement to revise the existing regulatory policy of the PSR established by IAEA Nuclear Safety Guide 50-SG- 012 after the IAEA announced new guidelines for PSR (IAEA Periodic Safety Review, NS-G-2.10). Therefore, this paper reviews the new guideline for PSR (IAEA Periodic Safety Review, NS-G-2.10) and the applicability of these new guidelines to the existing PSR system in Korea
