Simple thermal models representing surface and near-surface conditions of spent fuel casks are developed to assess the behavior of such cask regions to normal hot day conditions of 10 CFR 71 and bounding hot day extreme environments within the continental US. In general, it is found that the relatively simple regulatory conditions for hot day environments are reasonable predictors of bounding cask responses to actual hot day extremes. For cask configurations whose outer regions can be described as thin plates with adiabatic backfaces, designers need to assure adequate thermal design margins for temperature-sensitive surface components.
