| 摘 要： | 以福建宁德核电厂(宁德核电厂)常规岛电动给水泵(电泵)为研究对象,采用Flowmas-ter软件对从除氧器出口至蒸汽发生器入口的给水流程进行建模,计算在电泵切换瞬态过程中输送到蒸汽发生器的失水量,并对影响该失水量的主要因素进行敏感性分析。得出,宁德核电厂一期电泵切换瞬态过程输送到蒸汽发生器的失水量满足常规岛技术要求;电泵的最小流量阀容量、设备转动惯量以及电泵最高转速对失水量影响较大。

| Abstract: | Taking the motor-driven feed-water pump(MFP) on conventional island of Fujian Ningde Nuclear Power Plant as the object of study,a model of feed-water flow process from the outlet of deaerator to the inlet of steam generator has been established by using Flowmaster software,the deficit of feed-water delivered to the steam generator being calculated,and the sensitive analysis of the main affecting factors upon the deficit of feed-water being carried out.Results of analysis show that the deficit of feed-water ... |
