UF6 cylinders are in storage. The cylinder … UF6 cylinders are in storage. The cylinders consist of 1s/2s, hoke tubes, and 5A cylinders. The UF6 is contained in the cylinders, which are in DOT shipping containers (20PF1 and 6M containers). Calculations were performed that indicated that the theoretical pressure in some of the cylinders exceeds the service pressure (200psi) and some exceed the hydrostatic test pressure (400psi). DOE literature indicates that the burst pressure for a 5A cylinder is (approximately) 8,000 psi. The age of the cylinders is 1950s (to) 1980s. The potential pressure in the cylinders is estimated to be by liberation of fluorine gas in the cylinders. Access to the areas has been restricted. The path forward consists of further analysis, evaluation, and understanding of the issue.
