Abstract

Abstract

With a variety of new reactors being proposed, the demand for whole-core heterogeneous computing is increasingly urgent. Based on the needs and feasibility considerations, 2D/1D fusion method for solving the whole-core three-dimensional heterogeneous equation is raised. The international community has developed a number of such codes. This paper develops a 2D/1D fusion code, MOCHA₂D1D which is based on 2D modularity MOC, applying Sn difference method for 1D calculation. After verification, the accuracy meets the requirements of reactor physics calculation.
