Abstract

Abstract

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.
