摘要: 本文介绍了三维中子瞬态方程的改进准静态求解方法。给出了两个瞬态问题计算结果的比较;TWIGL结果与基准直接数值结果比较,其功率最大偏差为1.57%;CANDU堆模型,在功率上升达到最大值时的热中子通量与参考解的偏差为0.88%。因此,用改进的准静态方法求解三维中子瞬变问题,其结果是满意的,大大节省了计算时间。

Abstract: This paper describes the improved quasistatic method for solving reactor transient equations in three-dimensional region.Two transient problems are calculated, and results are compared with these by traditional direct numerical difference methods.For TWIGL problem the maximum error of power is 1.57%, for CANDU reactor model, near maximum power point, the maximum error of thermal neutron flux is 0.88% in comparing with the reference solution, hence the results are satisfactory the advantage of saving computation is demonstrated.
