摘　　要：讨论了压水堆核电厂冷却剂泵密封流量分配对化学和容积控制系统(RCV)设计可能产生的影响,并对其根本原因进行了探讨。定量计算了不同主泵密封流量分配导致RCV再生热交换器出口温度的改变,指出了RCV进行适应性更改的方向。采用热工-水力软件(Flowmaster)对上充泵在不同主泵密封流量需求下的能力进行了验证。The possible influences to Chemical and Volume Control System design caused by coolant pump seal water distribution are discussed.The essential reason is picked out in this paper.The temperature drop of charging flow at the regenerative heat exchanger outlet is calculated,and the feasible retrofits of the Chemical and Volume Control System are illustrated.The thermal hydraulic software Flowmaster 7.5 is employed to numerically investigate the possible capability of charging pump with different coolant pump seal requirements.
