Washington Closure Hanford manages the River Corridor Closure (RCC) Project for the U.S. Department of Energy. The RCC Project team is responsible for cleaning up about 218 square miles of Columbia River corridor at the Hanford Site. The corridor contains retired plutonium production reactors and support facilities, waste sites and burial grounds used during World War II and the Cold War that must be stabilized and maintained, or removed, to ensure worker safety and prevent potentially hazardous contaminants from entering the environment.
The RCC Project is organized around five projects to complete the work:
D4 Project – deactivates, decommissions, decontaminates and demolishes retired nuclear and support facilities
Field Remediation Project – cleans up and removes materials in waste sites and burial grounds
Reactor Interim Safe Storage Project – places retired plutonium production reactors into interim safe storage
Waste Operations Project – designates, transports, treats and disposes of waste and managing the Environmental Restoration Disposal Facility
End State and Final Closure Project – ensures that remediation under the RCC Project is completed to the standards of the Tri-Party Agreement and that the land is suitable for transfer to long-term stewardship
