摘　　要：文中选取MSR二级再热至7#高加正常疏水管路,选取多相流计算模型,对30%负荷及100%负荷工况时水平和垂直疏水管中的疏水流动状态进行分析,发现疏水管道气液两相流动存在从泡状流至气塞流转变的可能性,通过综合评价改善方案,对改善方案的应用和优化给出参考意见。In this paper,choosing the MSR 2th reheater to 7# HP-heater drain water piping,choosing the multiphase calculation model,this research analyzed drain water flow condition of the horizontal and vertical drain water piping flow at 30% units-load and 100% units-load.It was found the possibilities that the steam-liquid two-phase flow evolutes from bubble flow to slug flow.Through comprehensive evaluation of the improvement program,the application and optimization of the improvement program provide reference opinions.
