The Effect of an Annular Celotex(r) Gap on the 9975 Package
Following a drop test at the Westinghouse Savannah River Company (WSRC), radiographs of a 9975 drum package showed that separations, normal to the axial direction, had formed in the Celotex(R). Because the Celotex(R) acts as a thermal insulator, concerns arose as to the effect gaps in the material would have on the packaging components during and after a hypothetical fire transient. The effect of Celotex(R) gaps on the content temperature was estimated using a thermal model developed with the MSC/THERMAL(R) heat transfer software. The model included the effects of internal heat conduction and thermal radiation. Convection and thermal radiation boundary conditions were applied to the model. The thermal analysis supported the expectation that small separations in the fiberboard insulation will not degrade the thermal performance of the 9975 package in a Hypothetical Accident Conditions (HAC) fire.
