Abstract

Korea Hydro & Nuclear Power Co. (KHNP) has implemented engineering programs for operating nuclear power plants. Engineering programs are maintenance rule (MR), functional importance determination (FID), single point vulnerability (SPV) and functional equipment group (FEG). Recently, KHNP has developed engineering programs for APR1400 feedwater supplying system to establish the advanced engineering system and will verify the suitability of engineering programs through implementing in new nuclear power plant. Consequently, it is expected that the reliability of APR1400 feedwater supplying system will be improved by implementing engineering programs.

국내 가동원전은 안전성 및 설비 신뢰도 제고를 위해 엔지니어링 프로그램들을 이행하고 있다. 엔지니어링 프로그램에는 설비의 정비효과를 감시하는 정비규정(MR), 예방정비 프로그램 개발 및 설비관리 우선순위 결정을 위한 기능적중요도결정(FID), 발전설비 불시정지 최소화를 위한 발전정지유발기기(SPV) 및 효율적 작업관리를 위한 기능적설비그룹(FEG) 등이 있다. 최근에 건설 중인 APR1400형 원전도 운영초기 단계부터 엔지니어링 체계 정착을 위해 고유 설계특성을 반영하여 급수공급계통의 엔지니어링 프로그램들을 개발하였으며, 향후 운영단계에서 프로그램 이행을 통해 각 프로그램의 적합성을 검증할 예정이다. 결과적으로 신규원전 고유 설계특성을 반영하여 개발한 엔지니어링 프로그램 이행을 통해 APR1400 급수공급계통의 신뢰성이 향상될 것으로 기대된다.
