本文基于耦合求解的思想,轴向、径向均采用特征线法(MOC),通过开展2D/1D耦合MOC理论模型、模块化几何预处理方法研究,开发了2D/1D耦合MOC 3D中子输运求解程序MMOC,并开展了1D/2D/3D C5G7基准题验证。k_(eff)的相对误差分别为0.082%、0.045%、0.032%,该程序准确有效,计算精度满足中子输运计算的要求。

Based on the idea of coupling solution, the method of characteristic line (MOC) is applied in both axial and radial directions. By carrying out the 2D/1D coupling MOC theory and modular geometry preprocessing method, a 2D/1D coupling neutron transportation code MMOC was developed, and the 1D/2D/3D C5G7 benchmark was verified. The relative errors of keff are 0.082%, 0.045%, and 0.032%. The MMOC code is reliable and can satisfy the computational requirement of neutron transportation. © 2018 Editorial Board ...
