The Department of Energy reached preliminary cease waste removal status for Tank 14 at the Savannah River Site following the successful extraction of radioactive liquid waste. This marks the eighth old-style underground tank to reach this regulatory milestone in less than two years. The achievement reflects ongoing efforts to decommission legacy infrastructure and accelerate the site cleanup mission.

The Department of Energy's Office of Environmental Management has received concurrence from regulators that Tank 14 at the Savannah River Site has reached preliminary cease waste removal (PCWR) status after radioactive liquid waste was successfully removed from the tank.

Tank 14 has become the eighth old-style underground legacy waste tank at SRS to reach PCWR in under two years. Tank 3 received PCWR approval in September 2025.

DOE-EM Assistant Secretary Tim Walsh, who marked the tank closure milestone during his recent visit to SRS, said the site's liquid waste program is a testament to the integrated approach to the department's cleanup mission. "It's really a model for what is the art of the possible and what is being accomplished to speed up our mission here," he said.
