To ensure their safety, cylinders containing reactor grade UF/sub 6/ are transported in protective overpacks. An overpack is designed to protect the UF/sub 6/ cylinder in a fire at least 1/2 h in case of an accident. A thermal analysis was performed on a 30-in.-dia cylinder in a protective overpack to simulate various accident cases and compared with available experimental data. The analysis included the thermal performance of both a damaged and an undamaged overpack as well as the effect of moisture in the insulating layer of an overpack. The results indicate that an average cylinder surface temperature inside an overpack, after exposure to a fire for 1 h, is still below the level where appreciable UF/sub 6/ phase change would occur that could cause a cylinder to rupture.
