At 220 square miles, the River Corridor constitutes the largest cleanup territory at Hanford, divided into six geographical areas. Demolishing all remaining facilities and cleaning up the few remaining waste sites in this area will shrink the active cleanup footprint, reduce our overall carbon emissions, and free both funding and resources to be applied to other mission priorities. It also enables land to be released
for other uses.  Learn More >

The center part of the Hanford Site contains hundreds of legacy structures and waste sites from decades of nuclear fuel processing. Our focus is on risk reduction, with ongoing projects designed to move the 1,936 cesium/strontium capsules out of wet storage into a safe, secured configuration. Removing these capsules to dry storage allows deactivation of an aging storage facility, reducing the possibility of a radioactive release, and reducing long-term operating costs. In addition, there are more than 1,900 excess facilities and underground contaminated structures and waste sites in the River Corridor and Central Plateau
requiring remediation.  Learn More >

Contaminated groundwater exists beneath the River Corridor and Central Plateau. Fuel production, processing, and research activities over multiple decades resulted large volumes of contaminants released into the groundwater, some of which has reached the Columbia River. Plumes of contaminants have spread over 70 square miles. We treat over 2 billion gallons of groundwater annually at our six treatment facilities, manage hundreds of monitoring wells, and collect thousands of soil and groundwater samples annually to monitor risk. Nevertheless, we still have significant work ahead of us to further reduce risk to the nearbyColumbia River.  Learn More >

Another challenge we face is managing more than 15,000 cubic meters of legacy transuranic waste (TRU), currently in long-term storage at Hanford, which will require offsite disposition. We have ongoing projects to repackage and certify waste to ensure it is ready to be shipped to an underground disposal facility in New Mexico.  Learn More >

The Hanford Site was the location of the world’s first full-scale plutonium production reactor, as part of the Manhattan Project. The B Reactor, which operated from 1943 to 1968, produced plutonium for the atomic bomb that ended World War II. The B Reactor was given National Historic Landmark status in 2008. CPCCo maintains and preserves the B Reactor, and other historic pre-Manhattan Project facilities for public access and education, in cooperation with the National Park Service, as part of our operations portfolio. As part of our support, CPCCo will be providing critical infrastructure upgrades over the next five years, which will expand services and access to the park, and reduce long-term operating costs.  Learn More >

Our mission in the Central Plateau is critical to overall Hanford Site success, including the success of other Hanford contractors with portions of the cleanup mission. This includes storing containers of immobilized low-activity waste, produced by the Waste Treatment and Immobilization Plant through a vitrification process that transforms waste from tank farms into inert glass for long-term storage. It also includes storage for hazardous and mixes wastes generated by other Hanford cleanup activities, such as building demolition and site operations.  Learn More >

Our leadership is committed to our employees and supporting the next generation of our workforce, through enhanced partnerships with local and regional universities and new collaborative programs. These programs and partnerships, designed to attract and retain critical talent to support Hanford Site cleanup, will ensure that we will continue to develop capabilities within the local community to meet current and
future needs.  Learn More >

CPCCo is committed to shrinking the size of our carbon footprint, reducing greenhouse gas emissions in our facilities and operations, and lowering vehicle and equipment usage. Over the next decade, as we reduce our cleanup footprint, we will also reduce our office and industrial footprint, thereby reducing energy demands, heavy equipment rentals, fleet vehicles and fossil fuel consumption, as well as paper and non-recyclable office supplies.  Learn More >
