AP1000化学与容积控制系统调试经验反馈

化学与容积控制系统(CVS)是AP1000堆型的重要系统,控制反应堆冷却剂系统(RCS)水质、硼浓度和水装量。CVS系统调试是系统投运的先决条件,也是一回路冷试、热试等重要里程碑的重要支持系统。文章结合海阳核电二号机CVS系统调试实践,对调试期间的创新点和一些问题进行总结,以期对后续项目提供参考。

The chemical and volume control system(CVS)is an important system of AP1000 reactor type,which controls the water quality,boron concentration and water volume of the reactor coolant system.The debugging of CVS system is the precondition of system operation,and it is also an important support system which is an important milestone such as cold test,hot test and so on.Based on the commissioning practice of Haiyang Nuclear Power No.2 CVS system,this paper summarizes the innovation points and some problems during the commissioning period,in order to provide a reference for future projects.
