利用少群扩散理论和控制棒与靶件的等效扩散处理方法进行了高浓铀-重水栅的分析计算。栅格分为两类:(1)由12根和9根燃料元件组成的净堆栅格;(2)由燃料元件、控制棒和靶件组成的复合栅格。对所研究的栅格,临界计算的精确度为0.6％,控制棒和靶件效率的理论计算值在14％范围内与实验结果相符合。
The calculation and calculation of HEU - heavy water grid were carried out using the theory of small group diffusion and the equivalent diffusion treatment of control rod and target. Grids fall into two categories: (1) a net grid of 12 and 9 fuel elements; and (2) a composite grid of fuel elements, control rods and targets. For the grid studied, the critical calculation accuracy was 0.6%, and theoretical calculations for the control rod and target efficiency were within 14% of the experimental results.
