对硼浓度和不凝气体给堆芯冷却监测系统CCMS（ Core Cooling and Monitoring System ）压力容器液位L VSL测量引入的误差进行了量化计算。计算结果表明，2000 ppm的硼浓度对L VSL测量引入的误差可以忽略，对40000 ppm的硼浓度对L VSL测量引入的误差可达13％。对压力容器内充满不凝气体的极端情形，对L VSL测量引入的误差不超过2％。这些误差不会阻碍事故处理安全重要操作的执行。

The impact on Reactor vessel level monitoring of CCMS ( Core Cooling and Monitoring System ) due to boron concentration and non -condensable gas is analyzed , the result shows that the error induced by boron concentration at 2 000 ppm can be ignored , the error induced by boron concentration at 40 000 ppm will reach 13%.Under the extreme condition of the Reactor vessel full of non -condensable gas , the error induced will not exceed 2%.These errors will not hinder the implementation of safety related actions in accident manage -ment .
