摘要 根据对模块化矩阵特征线(MOC)方法进行的理论研究结果,采用C++语言编制模块化矩阵MOC程序。为验证该程序的计算精度和计算效率,对沸水堆(BWR)栅格、UO2组件、2D C5G7三个基准题进行计算。数值结果表明,模块化矩阵MOC方法具有良好的计算精度和较高的计算效率。 In the companion paper, Matrix MOC based on modular ray tracing was studied, the numeric properties of the coefficient matrix were analyzed and multi-group GMRES method was proposed. Based on these theories, a modular ray tracing MOC code was developed in CPP programming language. To verify the efficiency and accuracy, three benchmarks were computed, which are BWR lattice benchmark, UO2 assembly and 2D C5G7 benchmark. Numerical results of the benchmarks demonstrate that Matrix MOC based on modular ray tracing can obtain good efficiency and accuracy.
