蒸汽发生器在运行过程中发生换热管的泄漏是常见的事故。氢计是测量钠和覆盖气中氢杂质的在线测量仪表。在二回路中,为了监测蒸汽发生器热交换器管壁是否破损,用以避免其后更多的三
It is a common accident that the steam generator leaks during the operation of the heat exchange tube. Hydrogen meter is an online measuring instrument for measuring hydrogen impurity in sodium and cover gas. In the second circuit, in order to monitor the steam generator heat exchanger tube wall is damaged, to avoid the subsequent more three
