Zion Nuclear Station Decommissioning

ZionSolutions, LLC, a subsidiary of EnergySolutions, is a special-purpose subsidiary formed specifically to deliver integrated services and solutions for the safe cleanup and environmental restoration of the Zion Nuclear Station site. Located approximately 60 miles north of Chicago on the banks of Lake Michigan, this power station operated from 1974–1998. EnergySolutions has requested a license transfer from the U.S. Nuclear Regulatory Commission (U.S. NRC) to take control of the facility during the entire decommissioning phase. Once the decommissioning project is complete, the license will be transferred, along with the land, back to Exelon Corporation.

Tank Operation Contract (TOC) at Hanford

The Hanford tank farms are the largest and most complex environmental cleanup project facing U.S. Department of Energy (DOE). The challenges go beyond size and complexity.

To meet the challenges posed by the Hanford tank farms, EnergySolutions teamed with Washington Division of the URS Corporation and created Washington River Protection Solutions, LLC (WRPS), and then joined with AREVA to form the WRPS Team.

On May 29, 2008, the DOE awarded WRPS the Tank Operations Contract. DOE values the ten-year contract (a five-year base period with options to extend up to an additional five years) at $7.1 billion. WRPS assumed responsibility for tank waste mission activities at Hanford under the new contract on October 1, 2008.

Approximately 53 million gallons of residual radioactive and chemical waste is stored in 177 large aging underground tanks grouped in 18 farms at the 586 square mile Hanford site. Under the contract, EnergySolutions and its partners will safely maintain the tanks while beginning to conduct final retrieval and transfer of the waste and safe closure of the tanks.
