Description

As 1- D two node multi-group neutron diffusion problem solver which is used in nonlinear coarse mesh finite difference nodal method, unified nodal method(UNM) and semi-analytic nodal method(SANM) are compared in terms of 2-group and 8-group problems. Approximate UNM/ ANM and SANM with quartic effective source term showed very accurate results. As for the computation time, approximate UNM/ ANM is much more effective than SANM up to 8-group problem. However, SANM is expected to be more effective in many-group problems. The two methods can be used complementarily
