降温降压期间主系统参数控制

RCS Parameter Control During Cooling and Pressure Downing

核电厂换料大修主系统降温降压期间,要频繁的控制主系统的温度、压力、水装量、硼浓度的变化以满足电厂对于主系统工况的需求。通过对电厂降温降压期间水装量、主系统温度、压力、硼浓度控制方式进行分析并加以优化,来为换料大修降温降压系统控制提供参考。

The nuclear power plant refueling outage during the primary system to coolingand pressure downing,to frequent the main system to control the temperature and pressure changes,the amount of water loaded,the boron concentration of the power plant for the primary system to meet the needs of working conditions.By volume of water loaded during the cooling and pressure downing of the plant,the main system temperature,pressure,control boron concentration was analyzed and optimized to the cooling and pressure downing of the refueling outage control system for reference.
