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.



Moab

On the west bank of the Colorado River, three miles northwest of the City of Moab in Grand County, Utah, lies 16 million cubic yards of radioactive uranium mill tailings.

EnergySolutions was awarded the $98.4 million Department of Energy contract to begin clean up of the 130-acre Atlas Mill Tailings pile.

EnergySolutions will perform design and installation of a tailings-removal waste handling system, and initial tailings movement and operations to relocate the Moab tailings and associated wastes to a disposal facility 30 miles north of the Colorado River to a newly created and engineered embankment near Crescent Junction, Utah. The contract performance period is through September 2011.

Concerns over potential radioactive contamination of the Colorado River has long made the clean up and removal of the radioactive mill tailings a priority for Utah citizens, environmental groups and Utah's government leaders.

The Moab contract was awarded through a competitive bid process with the Department of Energy's office of Environmental Management under the National Indefinite Delivery/Indefinite Quantity contract.
