Also at its initial meeting, the board of managers selected Luis Reyes
as its chairman. Reyes is the former executive director for operations
at the Nuclear Regulatory Commission.

Warther most recently served as vice president of environmental
management at B&W Y-12 in Oak Ridge, Tenn., where he was responsible for
seven nuclear clean-up projects. Warther also spent nearly a decade with
the Department of Energy working on a variety of nuclear projects. He

submarine service and holds a bachelor′s degree in mechanical
engineering from Cornell University, a Master of Business Administration
from The Citadel and a master′s degree in mechanical engineering from
Virginia Tech.

'Bob has had a distinguished career executing high profile, large-scale
nuclear projects. Not only has he had great success in completing his
projects on time, but he brought them in under budget,? said Sullivan,
who also serves as USEC′s vice president for American Centrifuge and
chief engineer. 'When our strategic partners joined us, we looked
forward to tapping into their expertise to help us successfully complete
the American Centrifuge project. Bob is the latest example of that
relationship, and he is a welcome addition to our project leadership
team.?

In addition to providing advice and counsel to the program manager, the
deputy will also chair the Integrated Product Team. The team will serve
as a platform to address issues and potential issues by monitoring the
program′s budget, technical progress and production.

Program Background

The objective of the RD&D program is to demonstrate the American
Centrifuge technology through the construction and operation of a
cascade of 120 commercial centrifuge machines and to sustain the
domestic U.S. centrifuge technical and industrial base to ensure the
capability exists to meet future national security needs. This includes
activities to reduce the risks and improve the future prospects of
deployment of the American Centrifuge technology.

USEC intends to meet this objective through the construction and
operation of one complete demonstration cascade of 120 commercial
centrifuge machines and supporting infrastructure. USEC will also
demonstrate redundancy of the primary cascade support systems that will
be used in a production plant and will complete integrated testing of
those systems. The RD&D cascade would be incorporated in the full
commercial plant in Piketon, Ohio, which is planned to operate 96
identical cascades.

The RD&D program will support more than 1,000 direct jobs in Ohio,
Tennessee and several other states.

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