摘要
使用多功能中子学程序系统VisualBUS对聚变驱动次临界堆进行二维输运燃耗计算,分别使用与一维计算模型相同的材料份额、相同的初装质量和相同的初始keff三种情况与一维计算结果进行比较。计算结果的比较和分析表明,在相同材料体积份额和相同初装质量情况下,二维计算的中子学参数与一维计算结果差别较大,而在相同初始keff条件下,两者结果较为接近,可以满足设计方案的中子学目标。
The two-dimensional（2D） neutronics transport and burnup calculation and analysis were carried out by the home-developed multi-functional neutronics code Visual-BUS with its multi-group data library HENDL1.0/MG. Three cases, in which the material compositions, the initial loading and keff of the 2D calculation model are respectively equal to those of the one-dimensional（1D） calculation model were calculated to clarify the effect in these different models. There are great differences about neutronics parameters in former two cases. However, the results of the 2D model are close to those of the 1D model in the latter case. As a result, the neutronics parameters can satisfy the design objectives.
