Depleted Uranium Hexafluoride (DUF6) Conversion Project


The Uranium Hexafluoride (DUF6) Conversion Project provides for the design, construction and operation of two facilities, one at Portsmouth, Ohio and one at Paducah, Kentucky to convert approximately 700,000 metric tons of DUF6 stored at the two sites into a more stable chemical form suitable for beneficial reuse or disposal.

DUF6 was generated during the past active operation of the gaseous diffusion enrichment plants at Portsmouth and Paducah Sites. The Portsmouth DUF6 inventory is expected to be processed in approximately 18 years and Paducah’s larger inventory within 25 years. The construction and operation of these plants was mandated by Congress. In August 2002, DOE awarded a contract to Uranium Disposition Services, LLC (UDS) for design, construction and initial operation of the two facilities.
