Estimation of maximum temperature in a package subjected to hypothetical-accident thermal-test conditions

PDF Version Also Available for Download.

Description

A simple reading-the-graph procedure has been developed to provide a quick estimate of maximum temperature in a package during hypothetical-accident thermal-test conditions. The procedure, based on applying the analytical solutions of a transient thermal-diffusion equation for temperatures in a semi-infinite solid and in an infinitely long circular cylinder subjected to step surface temperature boundary conditions, is applicable to all packages, with or without an internal heat source, that are protected by rectangular or cylindrical thermal insulating overpacks. Simple to follow, the procedure provides a conservative estimate of package maximum temperatures during hypothetical-accident thermal-test conditions. To demonstrate its applicability, the procedure ... continued below

Simple to follow, the procedure provides a conservative estimate of package maximum temperatures during hypothetical-accident thermal-test conditions. To demonstrate its applicability, the procedure is applied to the Mound 9859 tritium trap package and two values of the thermal diffusivity of the insulation in the overpack.
