Evaluation of the use of homogenized fuel assemblies in the thermal analysis of spent fuel storage casks [PDF]
, 1999 Thermal analysis of spent fuel storage casks has generally been based on the assumption that heat released by the fuel assemblies is transported to the cask cavity only by conduction through the walls of the basket. This conservative assumption was adopted to compensate for uncertainties in modeling heat transfer in the cavity of a spent fuel cask ...
