摘要：

Our new method makes use of a CAD-based automatic modeling tool,MCAM,for geometry modeling and ray tracing of particle transport in method of characteristics(MOC).It was found that it could considerably enhance the capability of MOC to deal with more complicated models for neutron transport calculation.In our study,the diamond-difference scheme was apphed to MOC to reduce the spatial discretization errors of the flat flux approximation.Based on MCAM and MOC,a new 2D MOC code was developed and integrated into the SuperMC system,which is a Super Multi-function Computational system for neutronics and radiation simulation.The numerical results demonstrated the feasibility and effectiveness of the new method for neutron transport calculation in MOC.
