원자력 발전을 위한 장비 적격성 (Equipment Qualifivation for Nuclear Power Plants)
본 보고서는 원자력 발전소 내의 안전 준수 및 지속적 운영를 위한 지침, 원자력 발전 장비의 적격성 평가 과정 유지 및 감독을 위한 지침 등을 제공합니다.
Nuclear Power Plants (NPPs) are designed, sited, constructed, commissioned and operated in conformity with the applicable nuclear safety standards. The standards ensure an adequate margin of safety so that NPPs are operated without undue radiological risk to the plant personnel or members of the kna_cut. The basic principles employed in the design of systems and equipment are redundancy, diversity, physical separation. Designing and qualifying equipment for operation during the normal, and harsh environmental conditions provides assurance on avoidance of common cause failures due to environmental conditions including that resulting from accidents. Equipment Qualification is carried out to ensure the capability of the equipment to withstand the stresses of normal operation and harsh environment. Qualification ensures that identified equipment will be capable of performing their intended safety functions in the service conditions expected during normal operation as well as during accidents including seismic events. This safety guide provides the guidance for establishment and preservation of equipment qualification in an NPP to ensure its safe and continued operation, and for establishing a comprehensive programme for maintaining and overseeing the entire qualification process.
The objective of this safety guide is to provide guidance on the establishment and preservation of qualification of safety related electrical, instrumentation & control and active mechanical equipment of NPPs (e.g valves, pumps etc.) that perform safety functions in normal operation conditions and harsh environment expected during accident conditions.
