The U.S. government has granted newly formed company Hanford Tank Waste Operations & Closure a potential 10-year $45 billion indefinite-delivery/indefinite-quantity contract to carry out a range of duties at the Hanford Site.

The contractor, nicknamed H2C, comprises a team made up of three companies: BWXT Technical Service Group, Amentum Environment & Energy and Fluor Federal Services.

According to the Department of Energy’s Office of Environmental Management, the requirements under the Integrated Tank Disposition Contract to be performed at Hanford in Washington state encompass running tank farm facilities, including the retrieval and shutdown of single-shell tank waste, and the operation of waste receiving and treatment facilities.

H2C will also run the Waste Treatment and Immobilization Plant and perform core tasks such as project management, security and emergency services, and business performance requirements.

The new contractor must also submit a community commitment plan to the Energy Department.

The Hanford Site is one of several large-scale cleanup projects that EM oversees as part of its mandate of promoting the sustainability of the DOE’s nuclear mission.
