Effect of Thermal Properties on Thermal Response of Packages

Abstract

This study provides insight into the response of a representative idealised cylindrical package to the HAC fire transient as a function of the thermal properties of the overpack material. The results show that the relative resistances of the package material and surface determine the response of the package. For cases where the surface resistance is dominant, the package behaves like a lumped mass and the peak temperature and response time is determined by the conduction and energy storage parameters. For cases where the internal resistance is dominant, the heat generation becomes the dominant parameter in determining the peak temperature in the centre (containment vessel region) of the package.
