EnergySolutions Receives Private Letter Ruling Clearing Key Tax Issue for Zion Decommissioning

SALT LAKE CITY, UT, Jul 22 (MARKET WIRE) --
EnergySolutions, Inc. (NYSE: ES) announced today that it has received a
favorable Private Letter Ruling from the U.S. Internal Revenue Service
(IRS) concerning tax treatment of decommissioning funds related to the
company's Zion Nuclear Power Station project.

The IRS ruling concluded that the structure of the EnergySolutions project
will allow the company to assume control of decommissioning funds without
having to recognize gains or losses at the time of transfer.

In December 2007, EnergySolutions signed an agreement with Exelon
Corporation to accelerate the decommissioning and environmental
restoration of Exelon's Zion Nuclear Power Station site located in Zion,
Illinois. The project employs a license stewardship strategy whereby
EnergySolutions will conduct the decommissioning and site restoration
work as both owner and licensee of the power station. Following
completion of the project, the Zion property will be returned to Exelon.

EnergySolutions requested a Private Letter Ruling from the IRS to confirm
that the transfer of assets from Exelon to EnergySolutions, including
funds that have been set aside to pay for decommissioning activities,
would not trigger adverse tax consequences. The Private Letter Ruling
issued by IRS confirmed that the transfer will not trigger capital gains
or other income tax events.

"The IRS ruling represents a significant milestone in the development of
our license stewardship strategy," said Steve Creamer, EnergySolutions CEO
and Chairman. "We are pleased that the Zion decommissioning project
continues its orderly progress toward start-up."

Prior to commencing decommissioning operations, EnergySolutions must
receive license transfer approval from the U.S. Nuclear Regulatory
Commission.

EnergySolutions offers customers a full range of integrated services and
solutions, including nuclear operations, characterization,
decommissioning, decontamination, site closure, transportation, nuclear
materials management, processing, recycling, and disposition of nuclear
waste, and research and engineering services across the nuclear fuel
cycle.
