LEAKAGE RATE TEST EQUIPMENT OF ISOLATION VALVE AND TEST METHOD THEREOF

摘要

According to the present invention, leakage rate test equipment of an isolation valve in a reactor containment building can provide reliability and security when testing integrity of all valves penetrating through a reactor building, and prevent time delay for improving safety and performing a verification test in case of operation of a nuclear power plant. Moreover, the leakage rate test equipment comprises: a regulator; a tank; a leakage measurement device; a leakage rate measurement monitor; and a control box.
