摘要
根据1 000 MW压水堆核电厂的特点,对常规岛主给水泵设计输入进行了分析,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,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%能够满足电厂最大连续出力运行要求,并具有良好的经济性。
Based on the feature of 1 000 MW PWR nuclear power plant,the purpose of the paper is to analyze the 'design input and margin selection for the main feedwater pump in turbine hall,and it is found that the interface parameters between the nuclear island and conventional island under best estimate condition shall be used as input data for the selection calculatipn of the main feedwater pump parameters,while the pump shall consider 5%margin for flow-rate and 10%margin for resistance calculation,the result of selection calculation based on the above condition can fully meet the long term operation requirement,besides,from the point of view of investment,the result is also economic
