Abstract

In order to develop technology for an equipment qualification (EQ) test, which is an important process in localizing solenoid-operated valves used in nuclear power plants, we analyzed related regulations, test procedures, conditions, equipment, and acceptance criteria. EQ regulations for the solenoid-operated valve are classified as law, guide, and standard, and are subdivided according to test specimens and contents. The EQ test is composed of functional, normal-, and accident- condition tests. The solenoid-operated valve is aged under normal and accident conditions, which are predicted in the design conditions of a nuclear power plant, and the performance of the valve is measured by a functional test. The test method and procedure analyzed in this paper might be very useful for manufacturers as well as EQ testers.

원자력발전소 용 솔레노이드 밸브의 국산화에 필수 과정인 기기검증 기술을 개발하기 위해 관련 규정을 분석하고, 시험절차 및 방법, 시험조건, 시험장치 및 허용기준 등을 구체화하였다. 솔레노이드 밸브의 기기검증 규격은 법규, 가이드, 규정 등의 순으로 계층화되어 있으며, 시험기기와 시험항목에 따라 규정이 세분화되어 있다. 세부 규정인 IEEE를 분석한 결과 기기검증 시험은 크게 기능시험, 일반환경시험 및 사고시험으로 구분되어 있는데, 일반환경시험과 사고시험을 통해 발전소 환경과 동일한 조건에서 솔레노이드 밸브를 노화시킨 후 기능시험에서 노화된 밸브의 성능을 확인하는 방식으로 검증시험을 수행하도록 구성되어 있었다. 본 논문에서 제시한 솔레노이드 밸브의 기기검증 시험절차와 방법은 기기검증 수행자뿐만 아니라 밸브 제조사에게 매우 유용한 기술 자료가 될 것으로 판단된다.
