Central Plateau Cleanup Company (CPCCo) at DOE’s Hanford site

Nuclear facility deactivation, decommissioning, decontamination and demolition at DOE’s Hanford site

The Central Plateau Cleanup Company (CPCCo) is an Amentum-led team responsible for the safe, environmental cleanup of Hanford’s Central Plateau, a large U.S. Department of Energy (DOE) nuclear site near Richland, WA. The Hanford site is where plutonium for nuclear weapons were produced during World War II and the cold war. Hanford’s Central Plateau contains former fuel-processing facilities that once refined plutonium fuel into its final product and associated waste disposal areas. The Plateau is split into East and West areas containing five Canyon Facilities, the Plutonium Finishing Plant, waste storage and processing areas and numerous burial grounds.

CPCCo began operations at the U.S. Department of Energy’s (DOE) Hanford Site in January 2021 with a goal to deliver headline-worthy changes to safely achieve meaningful near-term goals and reduce risk, while accelerating the overall remediation schedule and minimizing lifecycle costs. CPCCo currently manages site operations; facility deactivation, decommissioning, decontamination and demolition; waste-site remediation; transuranic waste management; and development of decision documents to support regulatory requirements and oversight.

Project Highlights

  • With nearly 180 years of combined nuclear experience – including 60+ years at Hanford – our CPCCo partnership has decommissioned close to 1,200 facilities and dispositioned more waste than any other U.S. company.
