SALT LAKE CITY, UT--(Marketwire - December 11, 2007) - EnergySolutions, Inc. (NYSE: ES) signed an agreement today with Exelon Corporation to accelerate the decommissioning and environmental restoration of the Zion Nuclear Power Station site located in Zion, Illinois. Pending Nuclear Regulatory Commission (NRC) approval, EnergySolutions, Inc. expects to take possession of the facility in 2008 to begin decommissioning.

The decommissioning will be performed using state-of-the-art technology and rigorous environmental controls to protect human health and the environment and to preserve the lakefront and wetlands properties.
