摘要
本文介绍了反应堆物理计算中燃耗计算的一种方法,通过宏观截面随燃耗变化的参数表、插值方法及中子扩散方程的求解完成燃耗计算,计算结果与Shearon Harris堆的结果作了比较,它们基本上一致,该方法具有使用方便,计算时间较短,能满足一定精度要求等特点。目前该方法已用于实际的堆物理计算中,为工程设计提供了一种有力的工具。
A method of burnup calulation is introduced in calculation of reactor physic in this paper. Burnup calculation is completed by interpolation table of macroscopic cross section vs burnup, interpolated method and solving diffusion equation. The calculated result compared with shearon Harri s's result is satisfied. The method has characteristic of use friendly, less calculated time and occuracy demand. Now it is used in the practical calculation of reactor physic. A effective tool is provided for engineering design.
