The U.S. Department of Energy (DOE) is moving forward in its effort to design, build, and operate new facilities to convert its inventory of depleted uranium hexafluoride (UF6) to a more stable chemical form. The DOE maintains approximately 700,000 metric tons of depleted UF6 in about 57,000 cylinders stored at its Paducah, Kentucky; Portsmouth Ohio; and Oak Ridge, Tennessee, sites. Current DOE plans call for building and operating conversion facilities at the Portsmouth and Paducah sites, where the vast majority of depleted UF6 cylinders are stored. The plans also call for the depleted UF6 cylinders currently stored at the East Tennessee Technology Park (ETTP) in Oak Ridge to be transported to the Portsmouth site for conversion. This report presents a transportation impact assessment for the shipment of the 4,683 full depleted UF6 cylinders (containing approximately 56,000 metric tons) stored at ETTP that contain a total of 25 metric tons of enriched and normal uranium or that are empty is also considered. For completeness in addressing all reasonable alternatives in future National Environmental Policy Act (NEPA) reviews and to allow maximum flexibility in future decision making, the possibility of moving the ETTP cylinders to the Paducah site is also considered, to the same degree of detail as shipments to Portsmouth. Transportation by truck, regular train, and dedicated train is considered. The assessment includes estimates of both the radioactive and chemical hazards associated with the cylinder shipments. In addition, the report contains an analysis of the current and pending regulatory requirements applicable to packaging UF6 for transport by truck or rail and evaluates regulatory options for meeting the packaging requirements.
