SCALE5 is a very significant improvement over the existing version of SCALE. It contains many enhancements that add to its flexibility and reliability. Many new features have been added to existing modules and several new modules have been added to the code package. One of the more important additions is the new resolved resonance processor, CENTRM/PMC. This addition enables the code to properly process cross-sections for configurations that do not fit the limiting assumptions of NITAWL. For the problems presented in this paper, CENTRM/PMC/KENO V.a (or XSDRNPM) produces results comparable to those from MCNP. This new resonance processor enables a problem being modeled using multi-group cross-sections to have the accuracy of point-wise continuous cross-sections.
