反应堆大型热工水力分析程序计算结果不确定性的来源与对策

Sources and Strategies of Uncertainties ofCalculated Results in Large Thermal hydraulics Safety Analysis Code

以CATHARE程序为背景 ,从理论方法、实验技术、模型结构、数值技术、参数敏感性分析方法和基本不确定性计算方法等方面阐述了核反应堆大型热工水力分析程序计算结果不确定性的来源和相应的对策 。

Based on CATHARE code.the sources and related strategies of the uncertainties of calculated results in large thermal hydraulics code is stated from aspects of theory analysis method,test technology,model structure,numerical technology,the analysis method of parameter sensitivity and the calculating method of basic uncertainty and so on.And a kind of sensitivity analysis method and the quantitative calculating method of uncertainty is reviewed briefly.
