摘　　要：为了保证高放废液贮槽内氢气监测的可靠性,采取多重性的冗余监测方式,通过综合分析氢气监测原理和对监测方法的比较,结合实际工况,设计了一套抽气取样法的在线氢气监测系统,其中氢气监测仪表采用热导式分析原理,并且为了保证测量的准确可靠,采取了相应的预处理措施,最终实现了恶劣工况的在线氢气监测。For purpose of reliably monitoring the hydrogen in storage facilities for the high level liquid waste(HLLW),a multi-redundancy monitoring method was adopted.Through comprehensively analyzing the theory of hydrogen monitoring and comparing the monitoring methods as well as considering the actual working conditions,a hydrogen sampling-based on-line hydrogen monitoring system was designed,in which,the hydrogen sensor employs thermal conductivity analysis and relevant preconditioning measure to ensure accuracy of the measurement so as to realize on-line hydrogen monitoring under bad working environments.
