Given the growing industry need to store spent reactor fuel of increasingly higher burnups and
heat loads in dry storage casks, and eventually to transport that same spent fuel in
transportation packages, analyzing the performance of casks and other radioactive material
packages has become a greater challenge. Finite Element, Finite Difference, and Finite
Volume analysis computer codes, defined here as Computational Modeling Software (CMS),
are tools used by many licensees to analyze cask and package performance in the structural
