核级阀门的流体阻断试验是研究反应堆回路在紧急情况下特别是在设计基准事故工况下,核级阀门紧急关闭切断流体的能力。该项试验是核级阀门国产化进程中核级阀门功能鉴定试验里的一项难度很大的试验。为系统地掌握核级阀门功能验证试验中的流体阻断试验的技术和方法,为我国具备开展流体阻断试验的技术能力以及制定核级阀门流体阻断试验的试验标准提供坚实的技术基础,通过核能开发 The fluid-barrier test of a nuclear-grade valve is a study of the ability of a nuclear-level valve to shut-off an emergency shutdown of a fluid in an emergency, especially under design basis accident conditions. This test is a difficult test in the functional verification of nuclear valves in the process of localization of nuclear valves. In order to systematically master the technology and method of the fluid blocking test in the functional verification of the nuclear grade valve, it provides a solid technical foundation for our country to have the technical capability to carry out the fluid blocking test and to set the test standards for the nuclear-level valve fluid blocking test, Through nuclear energy development
