The Department of Energy’s Office of Environmental Management announced last week that it is preparing to receive a shipment of spent nuclear fuel from Penn State University’s research reactor. The fuel is being shipped to Idaho National Laboratory for research purposes.

DOE-EM said crews with the Idaho Cleanup Project recently fabricated and tested four stainless steel canisters that will be used to receive and store the used TRIGA fuel. (“TRIGA” stands for “Training, Research, Isotope, General Atomics.”)

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.

Who’s in the running for DOE Nuclear Lifecycle Innovation Campuses?

April 1, 2026, 9:36AMNuclear News

Today is the Department of Energy’s deadline for states to respond to a request for information on proposed Nuclear Lifecycle Innovation Campuses. Issued on January 28, the RFI marks the first step toward potentially establishing voluntary federal-state partnerships designed to build a coherent, end-to-end nuclear fuel cycle strategy for the country, including waste management, according to the DOE.

GAO: Clarification of HLW definition could save DOE billions

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.

Deep Isolation validates borehole disposal for recycled SNF 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.

U.K. government to take over Hunterston B for decommissioning

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.

On January 5, the Nuclear Waste Management Organization (NWMO), the not-for-profit organization responsible for managing Canada’s nuclear waste, announced that it has submitted to the Canadian government an initial project description for its proposed deep geologic repository to hold Canada’s spent nuclear fuel.

Return of the HB Line at SRS

The Department of Energy is bringing the HB Line facility at the Savannah River Site back on line to recycle surplus plutonium and produce uranium-plutonium mixed oxide (MOX) fuel for advanced reactors.

Restarting the facility will be a multiyear process and will yield opportunities for increased domestic production of isotopes with scientific and commercial value. The DOE said that once operational, the HB Line will accelerate the Office of Environmental Management’s plutonium disposition mission by 10 to 13 years while reducing the existing cost.

Opposites can solve nuclear waste problems working together

In these challenging times of ever-increasing political polarization and strong differing personal opinions, there is hope that diverse points of view can converge to create solutions for difficult problems if we remain focused on the common good.

For us, the common interest is a solution for the broken U.S. program to dispose of the growing inventory of spent nuclear fuel and high-level radioactive waste from commercial nuclear energy. We strongly believe this is critical to support and enable our projected continuation and expansion of safe, reliable, clean, affordable nuclear power to support the needs of our rapidly evolving national and global societies.

Amended DOE standard contract reduces SNF responsibility, report says

March 9, 2026, 7:27AMNuclear News

While changes the Department of Energy made to its standard contract for accepting spent nuclear fuel may help reduce federal liabilities, they provide “little to no assurance” that the government will ever follow through on its promise to take possession of the fuel, according to commentary from Matt Bowen and Rama T. Ponangi of the Center on Global Energy Policy at Columbia University SIPA.

NRC ends work on three proposed rules for securing spent fuel

February 26, 2026, 9:27AMNuclear News

The Nuclear Regulatory Commission on Wednesday announced it was discontinuing three rulemaking activities intended to enhance the security of a deep geologic repository and the protection of spent nuclear fuel.

The NRC said that, among other reasons, it has decided not to proceed with the previously proposed rules due to a change in agency priorities resulting from President Trump’s Executive Order (EO) 14300, “Ordering the Reform of the Nuclear Regulatory Commission.”
