| 摘 要： | 研究了高通量工程试验堆（HFETR）占栅元铍中孔控制棒物理特性。首先，采用CELL程序计算各组件的少群截面参数；然后分别对占栅元控制棒和占栅元铍中孔控制棒进行了堆芯物理计算，并对反应堆轴向热中子注量率分布、60Co产量以及控制棒价值做了比较。研究结果表明，占栅元铍中孔控制棒完全可以用于HFETR的反应性控制，而且可以提高反应堆的安全性和经济性。

| Abstract: | In this paper, the physical characteristic of the mid-beryllium control rod of HFETR is studied. Firstly, the few group cross section of every assembly is calculated by CELL code. Secondly, the core physical calculations of the setting up control rod cell and mid-beryllium control rod cell are carried out respectively, and the axial thermal flux distribution, the isotope yield and the control rod worth are compared. The result shows that the mid-beryllium control rod can be used for the reactor reactivity control and can improve the reactor’s safety and economy. |
