三代核电安全壳隔离阀C类泄漏率试验方法研究

Research on Test Method for C Type Leakage Rate of Containment Isolation Valve in the Third Generation Nuclear Power

某三代核电站安全壳隔离阀受制于现场系统和设备的配置,按照原有设计的安全阀C类泄漏率试验方法可实施性较差。针对此问题创新了安全阀C类泄漏率试验方法,该方法更加安全可靠,大大降低了进行安全阀C类泄漏率试验的难度,有助于提高核电厂的经济性及安全性。

The containment isolation valve in a third-generation nuclear power plant is subject to the configuration of field system and equipment,the C type leakage rate test method of the safety valve according to the original design is not easy to be implemented.In order to solve this problem,a new test method for C type leakage rate of safety valve is innovated.This method is more secure and reliable,and greatly reduces the difficulty of implementing the C type leakage rate test of safety valve,which is helpful to improve the economy and safety of nuclear power plant.
