| 摘 要： | 以秦山二期压水堆为参考堆型,对压水堆环形燃料结构进行热工水力分析方法研究。应用SAAF程序分析了从11×11到15×15等5种不同排列方式中不同尺寸的环形燃料棒的热工水力性能,综合最小偏离泡核沸腾比、压降和燃料芯块温度等参数确定了环形燃料组件最佳排列方式为13×13。本文研究结果为相关专业分析提供了初始计算模型。

| Abstract: | A typical Qinshan Phase-Ⅱ PWR plant was selected as the base case for methodology study of thermal-hydraulic analysis for the best array of annular fuel assembly applied in the PWR core. A range of arrays from 11×11 to 15×15 for different sizes was investigated by using a sub-channel analyzer named SAAF. On the consideration of minimum departure from nucleate boiling ratios, pressure drops and fuel temperatures, the most promising option was found to be the 13×13 array of annular fuel assembly. The calculation results in this paper provide initial calculation model for correlative analysis. |
