BETHESDA, Md. – Charles M. “Buddy” Holley of USEC’s Oak Ridge, Tenn., office has received USEC Inc.’s (NYSE: USU) annual Chairman’s Award for 2007. USEC Board of Directors Chairman James R. Mellor presented the award and cash prize to Holley at today’s board of directors meeting. USEC’s most prestigious employee award recognizes excellence and entrepreneurship in sustained, day-to-day performance throughout the year.

Holley serves as demonstration facility operations manager for USEC Inc.’s American Centrifuge program in Oak Ridge. He is responsible for the design, construction and upgrades, maintenance, staffing and operations at USEC’s full scale centrifuge testing facilities at the East Tennessee Technology Park, where he reports to Robert Eby, director of American Centrifuge program technology and process engineering.

Holley joined USEC in 2000 and developed the initial feasibility study for the American Centrifuge demonstration program in Oak Ridge. He also prepared the cost estimate and schedule for the refurbishment of the Oak Ridge centrifuge testing facilities and managed the initial development and demonstration project activities at the site.

This past year Holley and his team performed critical centrifuge machine testing that provided the basis for successful Lead Cascade operations and demonstrated to the board, investors and DOE that the machine design was capable of producing SWUs (separative work units of enriched uranium) as predicted.

“Buddy has worked on the U.S. gas centrifuge program from the beginning and I am proud to honor him with the 2007 Chairman’s Award,” Mellor said. “His knowledge, experience and dedication to developing U.S. centrifuge technology is a huge asset to USEC’s American Centrifuge program. Buddy’s leadership and insight have put us on a path to successful deployment of our centrifuge technology. He has been an inspiration to all who work with him.”

Prior to joining USEC, Holley held a variety of positions with Lockheed Martin Energy Systems and its predecessor at the Portsmouth Gaseous Diffusion Plant in the areas of program, project and engineering management. He previously worked for DOE centrifuge program contractors Union Carbide and Goodyear Aerospace on the development of the Advanced Gas Centrifuge program at Oak Ridge and Piketon, Ohio.

USEC Inc., a global energy company, is a leading supplier of enriched uranium fuel for commercial nuclear power plants.
