Overview | Projects

Washington Closure Hanford (WCH) managed the River Corridor Closure (RCC) Project for the U.S. Department of Energy from 2005-2016. 

The corridor contained retired plutonium production reactors and support facilities, waste sites and burial grounds used during World War II and the Cold War that needed to be stabilized and maintained, or removed, to ensure worker safety and prevent potentially hazardous contaminants from entering the environment.

The RCC Project was focused on three major work scopes:

D4 Project – deactivates, decommissions, decontaminates and demolishes retired nuclear and support facilities

Field Remediation Project – cleans up and removes materials from waste sites and burial grounds

Waste Operations Project – transports, treats and disposes of low-level radioactive, hazardous and mixed waste and manages the Environmental Restoration Disposal Facility
