| Abstract: | Two set helium safety valves are installed in the safety discharge system for the primary loop of 10MW High Temperature Helium Cooled Test Reactor(HTR 10), they are nuclear safety class 1 component and one of the key devices to guarantee the safety of HTR 10. The present paper gives the seal requirements and structural peculiarity of the helium safety valves. And the demonstration test for seal performance of the helium safety valves was carried out in special test system according to the requirement of ASME Section III code. The test result showed that the sealing performance of the helium safety valves can meet the design requirement and relevant nuclear code. |
