The chemical and volume control system functions to maintain the coolant inventory, to control the coolant chemistry and to adjust the boron concentration of the reactor coolant system.

化容系统的功能：维持主系统的水装量，控制主冷却剂的化学性能和调节主系统的硼浓度。

Taking endpoint temperature and endpoint carbon content as control target, oxygen-blown volume and added coolant were calculated, then endpoint control of convert steelmaking was realized.

同时，将炼钢的终点温度和终点碳含量作为控制目标，计算氧气的补吹量和冷却剂的补入量，实现转炉炼钢的终点控制。

This pump supplies make-up water to maintain the volume when the primary reactor coolant has contracted due to decrease of load.

该泵在主回路冷却水减少时，提供补充水以维持所需水量。
