开展压水堆燃料组件5×5棒束非均匀加热临界热流密度实验;介绍大型热工实验装置、5×5全长棒束非均匀加热实验本体和实验方法,并与哥伦比亚大学HTRF装置临界热流密度(CHF)实验数据及CHF关系式预测进行比较。实验结果表明:大型热工实验装置与HTRF装置CHF实验结果具有较好一致性。
The critical heat flux density experiment of non-uniform heating of 5 × 5 bundles of PWR fuel assemblies was carried out. The large-scale thermal experiment equipment and 5 × 5 full-length non-uniform heating test bodies and experimental methods were introduced. Density (CHF) experimental data and the CHF relationship prediction. The experimental results show that the experimental results of large-scale thermal experiment device and HTRF device are in good agreement.
