AP1000压水堆核电站主给水泵组的设计选型分析

Design Selection Analysis for Main Feedwater Pump Unit of AP1000 PWR

本文对第三代先进型压水堆AP1000首堆工程主给水泵组的设计选型进行了分析，对选择一回路最佳估算流量下的接口参数作为二回路主给水泵组的设计输入进行了论证．对主给水泵组的流量、扬程、电机功率等性能参数的设计选择过程进行了阐述。本文对后续AP1000堆型二回路主给水泵组的设计选型具有借鉴和参考价值。

This paper anaiyzes the design selection of main feedwater pump unit for the first AP1000 project as 3rd generation advanced PWR, and presents the interface parameter under primary loop Bestestimate flow condition as the design input to the secondary loop main feedwater pump unit. The design selection process of performance parameters such as flow, total head and motor power for main feedwater pump unit is introduced, which can be the guidance and reference for main feedwater pump unit of other AP1000 nuclear power plant.
