Contract Put in Place Two Months Ahead of ScheduleBETHESDA, Md., Mar 11, 2010 (BUSINESS WIRE) -- The United States Enrichment Corporation and United Steelworkers (USW) Local Union 689 at the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio, have reached a new labor agreement almost two months ahead of the expiration of the existing contract. Union membership voted overwhelmingly on Wednesday, March 10, to ratify a labor contract that will be in effect for five years.

Approximately 495 USEC employees are members of USW Local 689. A majority of the membership approved the contract proposal.

"This is a positive step forward for both the union and for the United States Enrichment Corporation as we look ahead to providing continued quality work at the Piketon site," said Bobby Graff, President, USW Local 689.

"Clearly the mission of USEC's Government Services will go through a transition over the next few years," said Mark Keef, general manager of USEC's Government Services. "The site will be moving from cold shutdown to decontamination and decommissioning work, as well as creating an energy park and exploring other possible initiatives. This contract cements a strong workforce that will be flexible and innovative as we face an increasingly competitive environment and the changes ahead.

"This contract demonstrates our strong relationship with the USW union. This five-year agreement maintains good jobs at good pay that supports the regional economy in southern Ohio," said Keef.

The United States Enrichment Corporation is a subsidiary of USEC Inc. (NYSE:USU), a global energy company and a leading supplier of enriched uranium for fuel for commercial nuclear plants.
