Abstract
Predicting specific thermal behavior of spent fuel assemblies involved in an accident during shipping is difficult because of the geometric complexity typical of the shipping casks. Models range from a simple expression like the Wooton-Epstein correlation (described by Bucholz 1983) to detailed finite difference or finite element calculations. Certainly, with enough computer resources and manpower, any given cask arrangement can be accurately analyzed for laminar conditions. However, the cost of such an effort would be prohibitive. Developing an analytical tool thus entails reaching a compromise between accuracy and speed and economy.
