Title:
TEST SYSTEM AND METHOD FOR MAIN STEAM QUICK ISOLATION VALVES, AND FAST REACTOR MAIN STEAM SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/161062
Kind Code:
A1
Abstract:
A test system and method for main steam quick isolation valves (5), and a fast reactor main steam system. The test system comprises a partial closure test device, which is used for controlling the main steam quick isolation valves (5) on a same loop to sequentially undergo a partial closure test one by one. The test system can simplify periodic test operations of main steam quick isolation valves (5) in a nuclear power plant, improve test efficiency, and save labor cost.
