The SCALE code system has become a major tool for criticality safety analyses. Sequences within SCALE are automated to provide resonance self-shielding (via BONAMI and/or NITAWL) prior to calculation of keff by KENO V.a or XSDRNPM. This paper presents a modification to the Dancoff correction factor formalism used by NITAWL. The modified Dancoff factor treatment eliminates a breakdown observed in the past, which had been previously attributed to the limitations of the Nordheim treatment utilized by NITAWL.
