Abstract
A homogenization technique is developed to account for the interassemb ly neutron leakage effect on the homogenized parameters within general ized equivalence theory. To assess its accuracy, the method is impleme nted into a two-group nodal diffusion model. Both one and two dimensio nal Boiling Water Reactor benchmark problems are considered. Compariso ns to fine-mesh results show an average of 30%, accuracy improvement i n the nodal power for the most heterogeneous case. (C) 1997 Elsevier S cience Ltd.
