Korea Hydro & Nuclear Power Co. (KHNP) has developed and implemented the maintenance effectiveness monitoring (MR) programs for the operating nuclear power plants. The MR program is developed by reflecting design characteristics of the operating nuclear power plants to monitor the plant performance for improving the safety and reliability. Recently, KHNP has built a new nuclear power plant, and developed the MR program to establish the advanced maintenance system by reflecting unique design characteristics based on the OPR1000 standard model. So, the MR program developed in this study has another characteristics in comparison with the OPR1000 standard model, and we will verify the suitability of the MR program through evaluating initial performance of the plant. The safety and reliability of the new plant will be improved by developing and implementing the MR program.

The systems of the nuclear power plant are designed based on the User Requirement Document, and Korea Hydro & Nuclear Power Co. (KHNP) implements preventive maintenance activities to keep the specific design function of the system consistently. To monitor the preventive maintenance effectiveness, KHNP has also developed maintenance effectiveness monitoring (MR) program based on NUMARC 93-01 since 2003, and has implemented the program in all operating plants. Recently, KHNP has upgraded MR programs by reflecting implementing experiences ; reestablishing the performance monitoring level, improving analysis for standby function and performance criteria for passive components, reestablishing the availability performance criteria and the performance criteria for the same type of components. These upgraded MR programs will contribute to enhance safety and improve equipment reliability through monitoring maintenance effectiveness.

국내 가동중 원전은 발전소 안전성 및 신뢰성을 향상시킬 목적으로 정비효과감시 프로그램(정비규정)을 개발하여 2009년부터 이행 중에 있다. 정비효과감시 프로그램은 발전소 전 계통을 기능단위로 분류한 후 관리대상 선정, 안전중요도 결정 및 성능기준 수립을 통해 발전설비의 정비효과를 감시하는 프로그램이며, NUMARC 93-01 방법론을 기반으로 발전소별 고유 설계특성을 반영하여 개발하고 있다. 최근 건설 중인 APR1400형 원전도 운영초기 단계부터 정비체계 정착을 목적으로 안전관련계통 정비효과감시 프로그램을 개발하였으며, 향후 초기 성능평가를 통해 프로그램의 적합성을 검증할 예정이다. 결과적으로 고유 설계특성을 반영하여 개발한 정비효과감시 프로그램의 이행을 통해 APR1400형 원전의 안전성 및 신뢰성이 향상될 것으로 기대된다.
