원전용 솔레노이드 밸브의 기기검증 절차 및 방법

Abstract

Key Words: Solenoid Operated Valve(솔레노이드밸브), Equipment Qualification(기기검증), Power Operated Valve(동력구동밸브), Nuclear Power Plant(원자력발전소)초록: 원자력발전소용솔레노이드밸브의국산화에필수과정인기기검증기술을개발하기위해관련규정을분석하고, 시험절차및방법, 시험조건, 시험장치및허용기준등을구체화하였다. 솔레노이드밸브의기기검증규격은법규, 가이드, 규정등의순으로계층화되어있으며, 시험기기와시험항목에따라규정이세분화되어있다. 세부규정인IEEE를분석한결과기기검증시험은크게기능시험, 일반환경시험및사고시험으로구분되어있는데, 일반환경시험과사고시험을통해발전소환경과동일한조건에서솔레노이드밸브를노화시킨후기능시험에서노화된밸브의성능을확인하는방식으로검증시험을수행하도록구성되어있었다. 본논문에서제시한솔레노이드밸브의기기검증시험절차와방법은기기검증수행자뿐만아니라밸브제조사에게매우유용한기술자료가될것으로판단된다.Abstract: In order to develop technology for an equipment qualification (EQ) test, which is an importantprocess 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 valveare classified as law, guide, and standard, and are subdivided according to test specimens and contents. TheEQ test is composed of functional, normal-, and accident- condition tests. The solenoid-operated valve is agedunder 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 analyzedin this paper might be very useful for manufacturers as well as EQ testers.
