Development of safety performance evaluation guidelines for CANDU nuclear power plants

The importance and usefulness of safety performance indicators were recognize Korea and SPIs for Korean nuclear power plants were developed through a gove funded project in 1997 by KINS with the cooperation of the Korea Electric Corporation (KEPCO). The PIs, currently used after one year trial application and modification, are composed of 8 indicators only for PWR plants because CANDU reactors have different characteristics with PWRs and relatively less operating experience than PWRs in Korea. Therefore the purpose of this study is to develope SPIs (Safety Performance for CANDU reactors). Two basic directions are set in the development of CANDU. One is the balance with current PWR PIs and the others is minimizing licence load. The CANDU SPIs are developed by comparing the COG PIs and current PWR PIs. Most of common indicators are selected and a couple of indicators rep CANDU characteristics are added. Also, recent international changes of environment on SPIs are reviewed and fu for upgrading Korean SPIs to the international level were suggested
