对核电厂常规岛辅助冷却水系统由板式换热器改为管壳式换热器并取消升压泵的方案特点进行了定性分析，指出了系统方案改进后的辅助冷却水系统正常停运时会产生水锤现象。通过对辅助冷却水系统建模定量计算了循环水泵停泵工况时的水锤最大压力，提出了通过调整阀门关闭时间消除水锤现象的防护方案并进行了计算验证。

ABSTRACT:This paper,first of all,qualitatively analyzes the characteristic of the auxiliary cooling water system of the conventional island of the nuclear power plant which uses the tube heater instead of the plate heater,pointing out that water hammer phenomena may be caused in the improved system. The maximum pressure of the water hammer when the circulating water pump is shut down is simulated and calculated. Finally the paper proposes the water hammer prevention solution of regulating the valve closing time and certifies the scheme by calculation.
