摘要
核电厂应用超声波流量计可以提高主给水流量的测量精度,进而实现小幅功率提升,对提高核电厂的经济性具有重要意义。国内核电厂只有AP1000正在使用此技术,缺乏充分的使用实践和经验,对安全监管提出了全新的挑战。本文研究了主给水超声波流量计在核电厂的应用经验和出现的问题,从安全监管的角度,指出了核电厂在使用过程中应关注的问题,并提出了相应的意见和建议。
The application of ultrasonic flow meters in nuclear power plants can improve the measurement accuracy of the main feed water flow,thus achieve a small power increase,which is very important to improve the economics of nuclear power plants.Only AP1000 is in used in domestic nuclear power plants,which lacks sufficient use practice and experience,posing a new challenge to safety supervision.This paper studies the application experience and problems of the main feed water ultrasonic flow meter in nuclear power plants.From the perspective of safety supervision,this paper sorts out the problems that should be paid attention in nuclear power plants,and puts forward corresponding opinions and suggestions.
