核电厂汽轮发电机及常规岛厂房漏氢监测系统开发

The Development of the Hydrogen Leakage Monitoring of Turbine Generator System

汽轮发电机漏氢监测是确保核电厂运行安全的重要监测项目之一,文章针对M310核电压水堆所采用的法国阿尔斯通设计的汽轮发电机组,根据其发电机氢气供应及氢气冷却系统运行经验增设汽轮发电机漏氢监测系统。系统开发包括:测点确定、氢浓度探测器选型、就地机柜选型及设计、主控室报警监视设计等方面的内容。

Hydrogen Leakage monitoring of turbine generator is the important monitoring project to ensure the safe operation of the nuclear power plant. Aiming at the turbine generator of M310 PWR nuclear power, devel- opment of turbine generator hydrogen leakage monitoring system was according to its hydrogen generator hydro- gen supply and cooling system operating experience. System development including： measuring points to deter- mine the content of the hydrogen concentration detector selection, placed cabinet design, the main control room alarm monitoring and other aspects.
