摘　　要：根据非能动氢气复合器(PAR)的工作状态特点和启动阈值、停止阈值、消氢能力、点火阈值等关键特性参数的要求,设计建立能够模拟安全壳内事故环境条件、在非能动条件下开展PAR关键特性参数验证试验的试验装置,制定相应的试验方法,开展启动阈值试验、启动时间试验、消氢能力试验和点火阈值试验等,获得PAR的关键特性参数。试验结果表明:PAR关键特性在不同的试验参数条件下测试结果也不同;在制定PAR消氢特性参数要求时需要限定试验方法和试验参数条件,以便获得统一的、定量的PAR的消氢特性参数。Passive autocatalytic hydrogen recombiners （PAR） are extensively used in the GRE-Ⅱ, GRE-Ⅱ＋, and GRE-Ⅲ NPPs. Based on the requirements for key parameters of PAR, such as working features, start and stop threshold, hydrogen removal ability and ignition threshold, the experiment apparatus is designed and constructed which can simulate the NPS severe accident condition and verify the PAR key characteristic parameters under passive condition. Test method is＇ established, and series experiments on the start and stop threshold, starting time, hydrogen removal ability and ignition threshold were carried out. The test results show that different test conditions will lead to differences in PAR parameters, for that reason, only limited methods and conditions are suggested to use to get the unified, measurably quantified PAR key parameters.
