Abstract
The shapes of the collision densities and the fluxes used in the resonance shielding calculations with the code NITAWL can be fully explained by the shapes of the cross-sections and the size of the slowing down range relative to the Nordheim integration interval. The way this Nordheim interval is chosen is liable to improvement but it is probably impossible to find an algorithm that satisfies every possible resonance. But the change from NITAWL in SCALE-3 to NITAWL in SCALE-4 shows an improvement. In addition the correction of the errors in solving the integral equation also improves the module NITAWL. (orig.)
