CPR1000主给水泵设计输入选择及裕量取值分析

根据CPR1000核电厂的特点,对常规岛主给水泵设计输入选择及裕量取值进行了详细的分析,指出应选择一回路最佳估算流量下的接口参数为设计输入,将给水泵的流量裕量取值为计算流量的5%、阻力裕量取值为计算阻力的10%就能够满足电厂最大连续出力运行要求,具有良好的经济性。

Study on Design Input and Margin Selection for Main Feedwater Pump of CPR1000 Nuclear Power Plant

As per the feature of CPR1000 nuclear power plant,the design input and margin selection of main feedwater pump on conventional island are analyzed.It is indicated that the interface parameters between nuclear island and conventional island under best estimate condition should be used as input data for the selection calculation of main feedwater pump,while the pump should consider a margin of 5% of calculated result for flow rate and a margin of 10% of calculated outcome for resistance,which can meet the operation requirement of maximum continuous output of power plant and has good economic efficiency.
