摘要
基于离散纵标方法开发了三维输运屏蔽程序CTDOS测试版。该程序可实现三维几何系统内中子-光子输运过程keff和固定源计算问题的求解。采用CTDOS程序对Takeda基准题第一模型、Kobayashi基准题第一模型进行了计算,keff计算结果与基准题及TORT计算结果的最大误差小于0.04%,群通量密度计算结果与基准题及TORT计算结果的平均误差约为3%。结果初步证明:CTDOS开发过程及功能是正确的,计算精度较高。
The 3-D discrete ordinates neutron and photon transport code CTDOS test version was developed.Neutron and photon transport problems of keff and fixed source calculation can be solved by the code.ModelⅠ of Takeda benchmarks and Kobayashi benchmarks,and the coupling problem of neutron-photon were tested by CTDOS.Compared with the results given by benchmarks and TORT,the maximum deviation of keff is 0.04%,and the average deviation of group flux is about 3%.The results show that the development process and functions are right,and the accuracy is satisfied.
