Expanded and applied sixteen neutron-energy-group cross-section library

The purpose of this work was fivefold: to develop an expanded neutron cross-section library containing approximately 1200 cross-section sets with the Hansen-Roach (H-R) sixteen neutron-energy-group structure; to provide an enhanced computational tool on a personal computer for criticality calculations; to provide consistent values of the effective scattering cross sections (sigma-s) for each set of the expanded H-R library, for selecting the resonance self-shielded cross sections (sigma-p); to develop a consistent technique for calculating sigma-p to select and apply specific self-shielded cross-section sets; and to apply the cross sections and the selection technique to a wide variety of criticality calculational benchmarks. 18 refs., 1 fig
