Abstract

A simple model was developed for the calculation of the coupled kinetics and thermal-hydraulics response of power reactor cores. The developed model was used for the analysis of the Special Power Excursion Reactor Test III (SPERT-III) E-Core and Loss of Fluid Test (LOFT) Experiment L9-3. The model prediction results were compared with the experimental data for the reactivity insertion and loss of secondary feed water transients without scram. The comparison showed that the model predictions are accurate enough to confirm the capabilities and adequacy of the model. It can be concluded that the model results provide confidence in the application of simple calculation models to the analysis of power transients.

简单计算模型对动力堆分析的能力

建立了一个简单的动力堆堆芯动力学和热工水力学耦合响应计算模型。所建立的模型用于特殊功率偏移堆试验III (SPERT-III) e -堆芯和流体损失试验（LOFT）实验L9-3的分析。将模型预测结果与实验数据进行了比较，分析了无停堆情况下二次给水瞬态的反应性插入和损失。对比表明，模型预测的准确性足以证实模型的能力和充分性。模型结果为简单计算模型应用于电力暂态分析提供了依据。
