COSINE软件包组件参数计算程序LATC中S_N输运模块的开发与初步验证

摘要: 本文论述了组件参数计算程序LATC的离散纵标（S_N）输运模块的理论模型。通过对基准问题的校验，验证了自主开发的组件参数计算程序LATC中基于一维、二维S_N理论及扩散综合加速收敛方法的输运模块。结果表明，LATC组件参数计算程序的S_N输运模块与基准解吻合良好，初步验证了LATC组件参数计算程序的S_N输运模块的正确性。

Abstract: This paper discusses the theoretical model of discrete ordinate (S_N) transport module, which is used in the assembly parameter calculation code LATC. Through the comparison of benchmark, the transport module was verified based on one and two -dimensional S_N theory and diffusion synthetic acceleration (DSA) method of the independent developed LATC code. The results show that S_N transport module of the LATC code is in good agreement with those benchmark tests. The correctness of S_N transport module in the LATC code is preliminarily verified.
