Hanford cleanup

The U.S. Department of Energy (DOE) is

responsible for one of the largest nuclear cleanup efforts in the world.

Managing the legacy of five decades of nuclear weapons production at various sites throughout the United States. One of those sites is Hanford. Located in southeastern Washington state, Hanford is a 586-square-mile site created in 1943 as part of the Manhattan Project, America’s effort to develop the atomic bomb.

Nowhere in the DOE complex is cleanup more challenging than at Hanford, where work involves large volumes of several different kinds of waste in a number of different forms. Hanford cleanup began in 1989, when a landmark agreement was reached between the DOE, the U.S. Environmental Protection Agency, and Washington state. Known as the Tri-Party Agreement, the accord established hundreds of milestones for bringing the Hanford Site into compliance with federal and state environmental regulations.

Considerable progress has been made

after nearly four decades of cleanup at Hanford, reducing the risk the Site poses to the health and safety of workers, the public, and the environment.

Hanford Tank Waste Operations & Closure's 

mission is to deliver exceptional performance in safely removing, treating, and disposing of tank waste at Hanford. H2C leads the nation’s largest and most complex radioactive waste cleanup, including closure of the legacy waste tanks containing 56 million gallons of radioactive and chemical waste.

Eventually, H2C will operate portions of the Waste Treatment and Immobilization Plant, providing final treatment and disposal of Hanford tank waste.

Our team brings the capabilities and vision necessary to reduce the nation’s environmental liability and risk, accelerate tank waste disposition, and decrease lifecycle costs — achieving the shared goal of solving one of the nation’s paramount environmental challenges in order to provide a positive legacy for future generations.
