均相流蒸汽发生器瞬态分析模型

A Homogeneous Flow Model for Transient Analysis of Steam Generators

本文介绍了压水堆核电厂蒸汽发生器的一维均相流瞬态分析模型。基于该模型开发的程序计算结果与法国在ＢＵＧＥＹ４蒸汽发生器上的试验结果及ＡＴＨＯＳ程序的计算结果较好符合。该模型可用于分析压水堆核电厂Ｕ型管自然循环式蒸汽发生器的热工水力瞬态过程。

This paper presents an one-dimensional homogeneous flow model for thermal-hydraulic transient behaviour of PWR steam generators.The calculated results of the code based on this model is in good agreement with the experimental data of BUGEY4 steam generator in France and the calculated data of ATHOS code. This model can be used to analyze thermal-hydraulic transient behaviour of inverted U-tube steam generators in PWR power plants.
