Abstract

Abstract

A method of Characteristics with Linear Source Approximation（LSA） is proposed in this paper,and the corresponding code TCM__L is developed.Numerical results show that the LSA MOC can get more accurate results than the Flat Source Approximation（FSA） MOC and SLC MOC,and the LSA MOC code can use less storage and shorter computing time when using large meshes.
