## Abstract

When deterministic neutron transport methods are applied to lattice or whole-core problems, the multi-group approximation is usually applied to the cross-sectional treatment for the energy domain. Due to the complicated energy behavior of resonance cross sections, the weighting spectrum for collapsing multi-group cross sections is very dependent on energy and space, which becomes a crucial challenge when analyzing a lattice or full-core configuration.
