化学和容积控制系统主要为反应堆冷却剂系统提供如下条件:①容积控制,即通过连续的下泄和上充,维持一回路中稳压器水位于设定值;②化学控制,如调节冷却剂中硼浓度,制控冷却剂pH值、含氧量、其它溶解气体含量以及控制冷却剂中的活性水平等;③向堆冷却剂泵提供轴封冷却注水和接受其回流水;④进行一回路的充
The chemical and volume control system mainly provides the following conditions for the reactor coolant system: (1) volume control, that is to say, to maintain the primary regulator water at the set value through continuous venting and charging; (2) chemical control, such as adjusting the coolant Boron concentration, control the coolant pH value, oxygen content, other dissolved gas content and control the level of activity in the coolant, etc .; ③ to the reactor coolant pump shaft seal cooling water and accept the return water; ④ a loop of Charge
