Exhibit 10.2

USEC INC.
1999 SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

Amended and Restated Effective
January 1, 2008

INTRODUCTION

     USEC Inc. desires to retain the services of, and provide rewards and incentives to, members of a select group of management employees who contribute to the success of USEC Inc.

     In order to achieve this objective, USEC Inc. originally adopted the Supplemental Executive Retirement Plan effective April 7, 1999 to provide supplemental retirement benefits to select members of management and highly compensated employees who become Members of this plan. This plan has been renamed, amended and restated, effective January 1, 2008, to reflect the requirements of Section 409A and is intended to continue to be an unfunded plan of deferred compensation for a select group of management or highly compensated employees, as provided in the Employee Retirement Income Security Act of 1974, as amended. It is intended that the provisions of this Plan with respect to Grandfathered Benefits have not been and shall not be materially modified from the provisions in effect on October 3, 2004, and the Plan shall be construed consistent with that intent. Non-Grandfathered Benefits for which payment commenced after December 31, 2004 and prior to January 1, 2008 have been paid in good-faith compliance with the requirements of Section 409A. This restatement shall not apply to benefits of Members who have no Non-Grandfathered benefits or who have benefits that were in pay status prior to January 1, 2008; such Members’ benefits shall be governed by the terms of the Plan in effect the earlier of October 3, 2004 or the date of the Member’s Termination of Employment.
