The cost to complete the cleanup of the Department of Energy’s Hanford Site in Washington state could cost as much as $589.4 billion, according to the 2025 Hanford Lifecycle Scope, Schedule, and Cost Report, which was released by the DOE on April 15. While that estimate is $44.2 billion lower than the DOE’s 2022 estimate of $640.6 billion, a separate, low-end estimate has since grown by more than 21 percent, to $364 billion.
The life cycle report, which the DOE is legally required to issue every three years under agreement with the U.S. Environmental Protection Agency and Washington State Department of Ecology (Ecology), summarizes the remaining work scope, schedule, and cost estimates for the nuclear site. For more than 40 years, Hanford’s reactors produced plutonium for America’s defense program.
Workers prepare to remove from a specialized transportation trailer the first of three sludge-settling tanks for Oak Ridge’s Mercury Treatment Facility. (Photo: DOE)
Workers with the Oak Ridge Office of Environmental Management (OREM) and its contractor UCOR have finished installing the first of three large sludge-settling tanks for the Mercury Treatment Facility at the site’s Y-12 National Security Complex. The tanks, each of which will be 38 feet tall and 15 feet wide with a capacity of 36,000 gallons, provide a visible sign of ongoing progress on the facility where much of the construction has so far been below ground.

Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, announced that it has injected more than 100 million gallons of clean artesian well water to neutralize shallow groundwater contamination underneath 33 acres of a former coal storage yard and the associated runoff basin at the site in South Carolina. According to Ashley Shull, senior scientist for the project, “100 million gallons is nine times more water than [is] contained in the Georgia Aquarium in Atlanta.”

The Department of Energy’s Office of Legacy Management, which oversees department legacy sites that have been cleaned of radioactive waste and environmental contamination, debuted its first podcast on December 15. Launched in honor of the office’s 20th anniversary, the podcast series includes four episodes, each featuring a different member of the DOE-LM team.

The Department of Energy is seeking the public’s input on the Hanford Site’s 5-year plan, which outlines planned cleanup work either to be completed or initiated at the former plutonium production site near Richland, Wash. The DOE updates Hanford’s 5-year plan annually to reflect current progress and ongoing integrated planning for future work at the site.

The Department of Energy’s Office of Environmental Management said a new regulatory partnership framework established in recent years by the Oak Ridge Office of Environmental Management (OREM), its contractor United Cleanup Oak Ridge (UCOR), the Environmental Protection Agency, and the Tennessee Department of Environment and Conservation (TDEC) is ushering in a new chapter of accelerated cleanup at the department’s Oak Ridge Reservation in Tennessee.

The Department of Energy’s Office of Environmental Management recently shipped for off-site disposal 14 sodium fluoride traps, or exchange vessels, from the C-310 Product Withdrawal facility at the DOE’s Paducah Gaseous Diffusion Plant site in Kentucky. DOE-EM said it has also eliminated the site’s entire inventory of chlorine gas cylinders.
