Helium Sampling and Analyzing System of 10MW High Temperature Gas-Cooled Reactor

10MW高温气冷堆的氦气净化系统由氧化铜床、分子筛床、低温吸附器等主要净化设备及其它辅助设备组成,气体采样分析系统由气相色谱仪、湿度计、红外分析仪组成。在投入HTR-10使用中,其湿度计和红外分析仪均能达到设计要求,实现了对反应堆一回路氦气中H2O、CO、CO2的连续监测。其气相色谱仪满足设计要求,实现了对反应堆一回路氦气中H2、O2、N2、CH4、CO、CO2的间歇取样分析。

The helium purification system of 10 MW high temperature gas-cooled reactor consists of the purification equipments and their accessories. The purification equipments include a copper oxide bed, a molecular sieve absorber, a low temperature absorber, and etc. The gas sampling and analyzing system is consisted of the gas chromatograph, moisture probe, and infrared analyzing instrument. The moisture probe and infrared analyzing instrument both conform to the design requirement, and consecutive inspection of H2O, CO, CO2 can be carried out for the primary helium circuit. The gas chromatograph can also meet the design requirement, and so the intermittent sampling and analyzing of H2, O2, N2, CH4, CO, and CO2 can be carried out for the primary helium circuit.
