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。
According to the characteristics of working status of passive hydrogen compound reactor (PAR) and the requirements of key parameters such as start threshold, stop threshold, hydrogen abatement ability and ignition threshold, the design and establishment of a model capable of simulating accidental environmental conditions in containment and carrying out under passive conditions PAR key parameters of the parameters of the test device validation test to develop the appropriate test methods to carry out the start-up threshold test, start time test, hydrogen abatement test and ignition threshold test to obtain the key PAR parameters. The experimental results show that the key characteristics of PAR have different test results under different experimental parameters. In order to set PAR parameters for desiccating hydrogen, it is necessary to limit the experimental methods and experimental parameters so as to obtain uniform and quantitative PAR parameters .
