USEC announced that it had not been able to conclude a deal for the short-term extension of uranium enrichment at the Paducah Gaseous Diffusion Plant in Kentucky, and the company will begin ceasing uranium enrichment at the end of May. The Paducah plant is the only U.S.-owned and operated uranium enrichment facility in the United States. USEC leases the plant from the U.S. Department of Energy. USEC will take steps to cease enrichment at the Paducah plant over the next month and to prepare the plant site for return to DOE. USEC expects to continue operations at the site into 2014 in order to manage inventory, continue to meet customer orders and to meet the turnover requirements of its lease with DOE.
