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,这种能力对于保障核反应堆的安全有着极其重要的意义。开展此项试验的技术研究工作,掌握试验的技术方法,对于促进核级阀门国产化进程、确保核反应堆的安全运行和安全防护具有深远的意义。本研究项目的目的是通过试验研究,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 The fluid-blocking test of a nuclear-grade valve is a study of the ability of a nuclear-grade valve to shut-off fluid shut-off urgently in emergency situations, particularly at design basis accident conditions. Such capabilities are of crucial importance in ensuring the safety of nuclear reactors. Carrying out the technical research work of this test and mastering the technical methods of testing have far-reaching significance for promoting the localization process of nuclear-grade valves and ensuring the safe operation and safety protection of nuclear reactors. The purpose of this research project is to systematically master the technology of fluid blocking test in functional verification of nuclear valves through experimental research
