Description
The good features of the Analytic Function Expansion Nodal (AFEN) method are utilized to develop a practical scheme for the multigroup diffusion problems, in combination with the Polynomial Expansion Nodal (PEN) method. The thermal group fluxes exhibiting strong gradients are solved by the AFEN method, while the fast group fluxes that are smoother than the thermal group fluxes are solved by the PEN method. The scheme is applied to a MOX-fuel loaded core with good results
