摘要 利用RALAP5/MOD3.2程序对蒸汽发生器(SG)倒U型管单相倒流实验进行建模计算。计算结果表明,已有的按管长对倒U型管进行分类建模会使得RELAP5计算的4根Ⅰ类倒U型管发生倒流,过大的估计了倒流流量。在此基础上,将未倒流管用集总参数法处理,倒流管进行进一步的划分,建立了改进的U型管模型。通过分析比较,新建的模型能比较准确地计算倒流流量。 Using the code RALAP5/MOD3.2 to model and calculate the experiment of single phase reversed flow of steam generator, the results show that it is inaccurate to calculate the reversed mass flow rate using the model, which models the inverted U-tube by its length, and the new model based on it can more accurately calculate the reversed mass flow rate. Lastly, a method applied to investigate the single phase reversed flow in inverted U-tube of steam generator of nuclear plant is put forward.
