The Department of Energy, in its 2023 Year in Review released on December 20, noted that its cleanup program in 2023 had successes in treating liquid tank waste, carrying out deactivation and decommissioning, remediating groundwater and soil contamination, and reducing risk at its various sites across the nation.

William “Ike” White, senior advisor in the DOE's Office of Environmental Management, said that the office “realized numerous accomplishments in 2023 that not only reduce risks but help position cleanup sites for the next phase of progress. In addition, our workforce’s efforts over the past year led to a cleaner environment while also boosting DOE’s national security missions, supporting scientific innovation, and enabling a better future.”

At Idaho National Laboratory, Department of Energy leaders joined tribal, state, and local officials; contractors; and workers on March 28 to mark a recent milestone with the state of Idaho nearly 25 years in the making. The milestone was the completion of a spent fuel wet-to-dry project more than nine months ahead of a 1995 Idaho Settlement Agreement deadline.

The Department of Energy’s Office of Environmental Management on May 27 issued a final request for proposals for the cleanup of the Idaho National Laboratory site, near Idaho Falls, Idaho, and the Fort Saint Vrain facility near Platteville, Colo. The 10-year contract for the projects—collectively called the Idaho Cleanup Project—has an estimated ceiling of about $6.4 billion.
