A 1960s Electrolux vacuum cleaner was among the more unusual items workers removed from one of the world’s oldest nuclear waste stores at the United Kingdom’s Sellafield nuclear site.

The Department of Energy’s Hanford Field Office and Washington State Department of Ecology (Ecology) will hold a virtual public meeting on April 30 to learn more about the siting, construction, and operation of a proposed Contact-Handled Waste Processing Treatment and Storage Area at the DOE’s Hanford Site near Richland, Wash.

New ultrasonic testing equipment being used by the Department of Energy’s Idaho Cleanup Project (ICP) to confirm the integrity of thousands of legacy waste drums is saving taxpayers tens of millions of dollars, the DOE’s Office of Environmental Management announced.

The technology allows ICP personnel to inspect the thickness transuranic waste drums held in storage at the DOE’s Idaho National Laboratory Site, ensuring they meet Department of Transportation minimum thickness requirements to be shipped for disposal at the Waste Isolation Pilot Plant in New Mexico. According to DOE-EM, if drums meet the DOT thickness requirements, they can be loaded directly into shipping casks without the need for an expensive overpack container, leading to a minimum cost savings of $26 million.

Oak Ridge National Laboratory has successfully removed legacy radioactive waste stored for more than five decades, marking a significant cleanup milestone. The Oak Ridge Office of Environmental Management (OREM) and cleanup contractor UCOR processed and shipped highly radioactive source material, including radium-226 and boron, out of state for permanent disposal.

Nuclear start-ups Deep Fission and Deep Isolation will collaborate on the management of spent nuclear fuel from Deep Fission’s advanced underground reactors under a memorandum of understanding signed by the companies.

The University of Sheffield announced that it has engaged in a new £1 million (about $1.29 million) research partnership with Sellafield Ltd., the U.K. Nuclear Decommissioning Authority, and the U.K. National Nuclear Laboratory that will seek to address some of the challenges of nuclear waste encapsulation by looking at new cement technologies to provide safe and reliable disposal solutions.

The Nuclear Waste Technical Review Board has recommended to the Department of Energy and Congress that they work together “to create a workable pathway to site, license, construct, and operate a geologic repository for the permanent disposal of spent nuclear fuel and high-level radioactive waste.”

The preservation of records, knowledge, and memory is recognized as an important component of nuclear waste management, preventing future generations from unnecessary interference with a waste repository and supporting future societies to make informed decisions about such sites.

The Department of Energy’s Office of Environmental Management announced that it has completed the commissioning of a new, nearly $500 million, large-scale ventilation system at its Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic waste in New Mexico.

The U.S. Supreme Court heard oral arguments on Wednesday in the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ consolidated interim storage facility in Andrews County, Texas. Both the NRC and ISP petitioned the Supreme Court to review a decision by the 5th Circuit Court of Appeals that invalidated the NRC-granted license for the facility. Those two cases were consolidated into one, NRC v. Texas, which was heard by the court.

Advanced reactor company Moltex Energy Canada said it has successfully validated its waste to stable salt (WATSS) process on used nuclear fuel bundles from an unnamed Canadian commercial reactor through hot cell experiments conducted by Canadian Nuclear Laboratories.

Nuclear Waste Services (NWS), which manages the disposal of the United Kingdom’s low-level radioactive waste, announced this week that a major milestone has been reached at its Low Level Waste Repository in West Cumbria, England, as work begins on the final capping of legacy disposal trenches and vaults at the site.

The United Kingdom’s Nuclear Decommissioning Authority has announced that it will establish a Plutonium Ceramics Academic Hub with the Universities of Manchester and Sheffield. The announcement follows a decision by the U.K. government in January to immobilize the country’s inventory of civil separated plutonium at the Sellafield nuclear site, mitigating the material’s long-term safety and security risks.

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year U.S. dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

The U.K. government’s Nuclear Waste Services said it has identified three “areas of focus” in its search to find a suitable site and a willing community to host a geologic disposal facility (GDF) for the country’s most hazardous radioactive waste. The areas are within three communities currently involved in the siting process—Mid Copeland and South Copeland in Cumbria, and East Lincolnshire, England.

Nuclear Newswire has learned that the Trump administration last week requested that all members of the Nuclear Waste Technical Review Board resign, except for the board’s chair, Peter Swift.

Finland’s Radiation and Nuclear Safety Authority (STUK) stated that if everything goes well, it can complete the assessment of the operating license for the country’s deep geologic repository for spent nuclear fuel “well before the end of the year.”

A recent Bulletin of the Atomic Scientists article cautions that uncertainty regarding the management of wastes generated by small and advanced reactors could drive up costs, making them uncompetitive with existing light water reactor technology.

Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from October through December 2024.

The Department of Energy has agreed to hold a 30-day review and comment period on a draft environmental analysis associated with a proposed plan for retrieving, grouting, and transporting some of Hanford’s low-activity tank waste for out-of-state disposal.
