| 中文摘要: |
| 将带不完全LU分解预处理的广义共轭残量（ILU-GCR）算法用于高温气冷堆中子时空动力学程序中形状函数的计算，通过与几种经典迭代方法比较，ILU-GCR算法的优势比较明显，可以达到实时仿真计算要求.对给定功率的高温气冷堆模型，模拟了“弹棒”事故情况下考虑过功率保护与ATWS两个过程中堆芯反应性、堆内各能群中子平均注量率、堆芯相对功率、堆内温度等物理量随时间变化，计算结果与理论分析一致。 |

| In the neutron space-time kinetics computation program for High-Temperature Gas-Cooled Reactor,Generalized Conjugate Residual algorithm pretreated by incomplete LU decomposition （ILU-GCR） is used for dealing with the shape function.Compared with classical methods,ILU-GCR algorithm has obvious advantages.For the supposable HTGR model,the variance of the core reactivity,the average neutron flux of each group,the relative power and the temperature along with time are computed for the dynamic simulation of the control rod ejection accident under conditions of over power protection and ATWS. |
