The thermal analysis performed on the cylinder protective overpack proved that the new 2-1/2 ton cylinder protective overpack is in compliance with the design criteria; i.e., it protects a 30B cylinder inside the cover at least 1/2 h in a fire. The efffect of a stainless steel stepjoint does not contribute significantly to the heat transfer of the inner liner. In case of moisture in the insulation layer, the results of this analysis would provide somewhat lower temperature than the real situation due to an increase in the thermal conductivity of the insulation layer with moisture. These results were all based on an undamaged protective overpack over a fire. If the overpack is damaged, the effect of moisture might be to increase the temperature of the cylinder by condensing on the surface of the cylinder. Within a range of an oil fire somewhere between 1500/sup 0/F and 2100/sup 0/F, the protective overpack is effectively protecting the cylinder more than 1 h without any significant increase in the UF/sub 6/ temperature. 5 refs., 9 figs.
