2D/1D fusion method solutions of the three-dimensional transport OECD benchmark problem C5G7 MOX

Abstract

The method of characteristics (MOC) code CRX solves the three-dimensional transport problem by the 2D/1D fusion method, in which MOC is used in radial 2D calculation and S-N-like methods are used in axial 1D calculation. The CRX code was used to provide the solutions for the three-dimensional OECD benchmark problem C5G7 MOX and the results were submitted to OECD and documented in the OECD report. This paper provides a description of the 2D/1D fusion method for three-dimensional transport calculation and presents additional work implementing several improved features performed since the submittal of benchmark solutions, with comparison of the results.
