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. PCWR is a regulatory milestone in the closure of SRS’s old-style waste tanks, which were built in the 1950s to store waste generated by the chemical separations of plutonium and uranium.

The Department of Energy’s Office of Environmental Management announced that its Oak Ridge Office of Environmental Management (OREM) is setting a new benchmark in cleanup progress at the Tennessee nuclear site—conducting demolition of two former Manhattan Project–era uranium enrichment facilities in a single year.

The Department of Energy’s Office of Environmental Management has announced that its Idaho Cleanup Project (ICP) recently received department approval for the conceptual design for a spent nuclear fuel staging facility project at Idaho National Laboratory.

Researchers at Pacific Northwest National Laboratory are exploring methods of using artificial intelligence and machine learning to better optimize formulas for stabilizing low-activity radioactive waste in glass through the vitrification process.
The work is helping inform waste vitrification activities at the Department of Energy’s Hanford Site in Washington state. The DOE is currently commissioning the Low Activity Waste Facility at Hanford’s Waste Treatment and Immobilization Plant (WTP), which will be used to vitrify portions of the site’s nearly 56 million gallons of radioactive and chemical waste.

Claiming the Department of Energy is backing away from commitments made in a 2023 settlement agreement with the state, the New Mexico Environment Department (NMED) is proposing revisions to the Waste Isolation Pilot Plant operating permit. The revisions would prioritize the disposal of waste generated in New Mexico at WIPP, including legacy radioactive waste from Los Alamos National Laboratory.

Japan will study the possibility of siting a deep geologic repository for high-level radioactive waste on the remote island of Minamitorishima, about 1,200 miles southeast of Tokyo.
Masaaki Shibuya, mayor of the village of Ogasawara, reportedly expressed his willingness to allow Japan’s government to proceed with a preliminary survey, called a literature survey, of the island, which is one of several within the Ogasawara Islands.

When the Department of Energy’s Advanced Research Projects Agency–Energy launched the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program in 2022, it posed a challenge that the nuclear industry had never seriously confronted before: how to design waste management solutions that anticipate the coming shift to advanced reactors and not merely retrofit existing systems built for an older generation of technology. The program’s objectives were ambitious—reduce disposal footprint, enable scalable pathways for unfamiliar waste streams, and build the technical foundations for future disposal—yet also tightly grounded in the realities of emerging nuclear fuel cycles. For the nuclear community, this was a timely call. Advanced reactors were accelerating toward deployment, but the waste management systems needed to support them had not kept pace.

A clearer definition of what constitutes high-level radioactive waste could save the Department of Energy’s Office of Environmental Management “tens of billions of dollars” in waste management costs and accelerate its cleanup schedule by decades, according to a report by the U.S. Government Accountability Office.
DOE-EM’s efforts to manage waste resulting from legacy spent nuclear fuel reprocessing have been hindered for decades by the ambiguity of the statutory definition of HLW as laid out in the Atomic Energy Act and Nuclear Waste Policy Act, the report states. While admitting that the DOE has taken steps to overcome this ambiguity, the GAO says that the department has not fully evaluated all available opportunities to treat and dispose of waste more economically as either transuranic or low-level radioactive waste.

Waste disposal technology company Deep Isolation Nuclear has claimed that results of a study it conducted with reactor developer Oklo demonstrate that deep borehole disposal could be an option for disposing of high-level radioactive waste generated from the recycling of advanced reactor fuel.

Beginning April 1, the U.K.’s Nuclear Decommissioning Authority (NDA) and its subsidiary Nuclear Restoration Services (NRS) will take over the closed Hunterston B nuclear power plant for decommissioning. Located in North Ayrshire, Scotland, Hunterston B was shut down in 2022 after 46 years of service and is one of seven advanced gas-cooled reactor stations owned and operated by EDF Energy in the United Kingdom.
