Two-group CMFD accelerated multigroup calculation with semi-analytic nodal Kernel

  • 1. Seoul National University, Taejon (Korea, Republic of)

Description

The Coarse Mesh Finite Difference (CMFD) formulation or the nonlinear nodal method has been widely used in the solution of two-group problems providing high solution efficiency. In this paper, the two-group formulation is applied to multigroup problems as a means of acceleration. First, a new form of the semi-analytic nodal method (SANM) is derived to solve a multi-group one-node problem, and the SANM Kernel is then implemented within the framework of the two-group CMFD formulation involving dynamic group condensation. The efficiency of this scheme is investigated with a set of fast reactor problems
