Hanford Cleanup Projects
Focus Areas in Cleanup Oversight
Each of the focus areas below represents a significant component of the Department of Energy’s cleanup mission and carries important implications for our region.
Cleanup efforts along the Columbia River focus on decommissioning reactors, removing contaminated soil, and protecting groundwater. These actions help ensure the long-term health of one of the Northwest’s most vital water sources.
Grouting is used to immobilize radioactive waste and decommission contaminated structures by filling voids with concrete-like material. This reduces the risk of future leaks and supports long-term site stability.
The K Area includes former reactor sites and support buildings. Cleanup activities here include structure demolition, waste packaging, and soil remediation near the river corridor.
Also known as the Vit Plant, the WTP will convert millions of gallons of radioactive tank waste into stable glass through a process called vitrification. This is a central part of Hanford’s long-term risk reduction strategy.
Hanford’s groundwater treatment systems remove hazardous contaminants like chromium, uranium, and nitrates to protect drinking water and the Columbia River. This includes multiple pump-and-treat operations across the site.
TRU waste consists of highly radioactive materials that are packaged and prepared for shipment to permanent disposal facilities outside Washington State. This is a critical step in reducing long-term storage risks.
Over 1,900 cesium and strontium capsules, previously stored in underwater pools, are being moved to new dry storage systems for improved safety and security.
Hanford’s underground tanks hold millions of gallons of chemical and radioactive waste, some of which have leaked. Ongoing work includes retrieving tank waste and addressing known and suspected leakers to prevent further environmental damage.
Located near Richland, the 324 Building contains highly contaminated soil under its foundation. Specialized cleanup efforts are underway to safely excavate the soil while protecting surrounding areas and the public.
