NITAWL-III - Functional Modules

NITAWL-II applies the Nordheim Integral Technique to perform neutron cross-section processing in the resonance energy range. This technique involves a fine energy group calculation of the slowing-down flux across each resonance with subsequent flux weighting of the resonance cross sections. The major function of NITAWL is its conversion of cross-section libraries from a problem-independent to a problem-dependent form. However, NITAWL also assembles group-to-group transfer arrays from the elastic and inelastic scattering components and performs other tasks in producing the problem-dependent working library.
