CEFR二回路中冷却介质钠的品质高低直接关系到二回路的安全运行。二回路钠分析监测系统的功能就是监测二回路钠中杂质的含量。该系统的监测包括了在线监测和取样分析两个功能。在线监测是通过监测设备—阻塞计时时监测二回路钠中氧和氢的含量;取样分析是通过该系统的取样器,将系统内的钠样品转移至分析化学实验室,通过化学分析的方法分析样品中的氧、碳、氮、钙、铁、钾、氯等多种杂质的含量。图1示出了阻塞计的实物图,图2示出了取样器的实物图。
CEFR secondary circuit cooling medium, the quality of sodium is directly related to the safe operation of the second loop. The function of the secondary loop sodium analysis and monitoring system is to monitor the content of impurities in the secondary loop sodium. The system monitoring includes online monitoring and sampling analysis of two functions. On-line monitoring is through the monitoring equipment - to monitor the oxygen and hydrogen content of the sodium in the secondary circuit during the choking time; sample analysis is through the sampler of the system, transferring the sodium sample in the system to the analytical chemistry laboratory for analysis by chemical analysis Samples of oxygen, carbon, nitrogen, calcium, iron, potassium, chlorine and other impurities in the content. FIG. 1 shows a block diagram of the blocker, and FIG. 2 shows a physical view of the sampler.
