An alternate formulation of the two-group transverse-integration-based nodal expansion method is presented. In this formulation, the two-group problem is formulated by using the relationship between the group fluxes derived from an analytical procedure. As a result, a simplified procedure for the thermal group is suggested. The numerical results of the benchmark problems show that the new formulation of the nodal expansion method has the potential to accurately solve multidimensional problems with a considerable reduction in the computational cost required by the conventional two-group scheme.
