USEC Names Paul Sullivan Vice President of American Centrifuge Following Russell Starkey Retirement Announcement

USEC Inc. (NYSE:USU) today appointed Paul Sullivan vice president of American Centrifuge, effective July 1, 2009. In this position, Sullivan will oversee all aspects of the American Centrifuge technology’s research and development and the construction of the American Centrifuge Plant in Piketon, Ohio.

Sullivan replaces Russell Starkey, who has informed the company of his intention to retire at the end of the year. Starkey will continue to serve as an officer with the Company through the transition, reporting directly to USEC President and CEO John K. Welch.

"USEC is grateful to Russ for his 12 years of service to the company including as general manager of our Paducah plant, at headquarters as vice president of operations and finally as vice president of the American Centrifuge program. There isn’t much at USEC today that hasn’t benefited from Russ’ involvement,” said Welch. "Under his leadership, we have made significant progress on the American Centrifuge Plant and have moved closer to our goal of beginning commercial operations. We are very fortunate to have someone with Paul’s expertise and background to see us through to the finish line.”

Sullivan previously served as USEC’s vice president of operations and chief engineer, where he was responsible for USEC’s Paducah plant production operations and contract work for the U.S. Department of Energy (DOE) at the Paducah, Ky., and Piketon, Ohio, plant facilities. While Sullivan will remain as chief engineer, the general managers of USEC’s Paducah plant and USEC Government Services in Piketon will report to Bob Van Namen, senior vice president of uranium enrichment, on an interim basis.

Sullivan brings to the American Centrifuge program experience in leading major construction projects. During a 34-year Navy career, Sullivan served as Commander of Naval Sea Systems Command, Chief Engineer of the Naval Sea Systems Command and Program Manager of the Virginia and Seawolf submarine classes. Under his leadership, American shipyards delivered 22 new ships, 63 major ship overhauls and more than 140 private sector overhauls.

USEC’s American Centrifuge Plant, under construction since 2007, has a planned initial capacity of 3.8 million separative work units from approximately 11,500 AC100 series centrifuge machines. USEC’s American Centrifuge technology is based on technology initially developed by DOE during the 1970s and ‘80s. USEC has modified and improved this technology through the use of modern materials, advanced computer-aided design, digital controls and state-of-the-art manufacturing processes.
