Item 1.01 Entry into a Material Definitive Agreement.

On August 20, 2007, USEC Inc. ("USEC" or the "Company") entered into a contract with ATK Space Systems Inc., a subsidiary of Alliant Techsystems ("ATK"), and Hexcel Corporation ("Hexcel") for carbon fiber material and related carbon fiber products used in the manufacture of components for centrifuge machines to be used in USEC’s American Centrifuge uranium enrichment plant in Piketon, Ohio.

Under the agreement, Hexcel will increase its manufacturing capacity and USEC will purchase from Hexcel a specified amount of carbon fiber material sufficient for the approximately 11,500 centrifuge machines expected to be deployed in the American Centrifuge plant. The agreement provides for a fixed price for this carbon fiber material, with a provision for escalation related to general inflation. The agreement also provides USEC with an option for Hexcel to provide related carbon fiber products at a fixed price plus material costs and escalation related to general inflation. The agreement provides for a specified range of carbon fiber material to be purchased monthly and includes purchase and delivery incentives. ATK will place orders under the terms of the agreement for its commercial production of rotor tubes for centrifuge machines.

The contract period of performance runs through December 31, 2011.

ATK and Hexcel Corporation are key suppliers for the American Centrifuge plant. ATK has been working on the American Centrifuge project since 2003 and is currently performing work under a time and material contract entered into in 2005 that expires on December 31, 2007. USEC and ATK are also parties to an agreement entered into in May 2007 relating to the production of rotor tubes for centrifuge machines for the American Centrifuge plant. This agreement terminates upon the execution of a long term rotor tube production contract with more defined terms and conditions, including price.
