DOE report: Cost to finish cleaning up Hanford site could exceed $589 billion
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.
