The Department of Energy’s Office of Environmental Management said it will use a new simulator to help train operators on the safe and efficient movement of a remotely operated crane at the Defense Waste Processing Facility (DWPF) at the Savannah River Site in South Carolina. The DWPF, where Savannah River’s liquid high-level radioactive waste is vitrified and placed into storage containers, uses an unmanned bridge crane system to install and replace equipment in the high-humidity, high-radiation, and harsh chemical environment of the facility’s processing cells.

The Nuclear Regulatory Commission is discontinuing its rulemaking activity, “Long-Term and Unattended Water Makeup of Spent Fuel Pools,” and denying a petition for rulemaking. The new rule, as requested by the petitioner, would have required nuclear power plant licensees to ensure that their spent nuclear fuel pools are capable of cooling and maintaining water levels during extended power outages.

Nuclear waste disposal technology company Deep Isolation announced it has successfully completed Project PUCK, a government-funded initiative to demonstrate the feasibility and potential commercial readiness of its Universal Canister System (UCS) to manage TRISO spent nuclear fuel.

Canada’s Nuclear Waste Management Organization has selected five companies it is to work with to design and plan the organization’s proposed deep geologic repository for spent nuclear fuel. As the owner of the project, the NWMO will be working with WSP Canada, Peter Kiewit Sons (Kiewit), Hatch Ltd., Thyssen Mining Construction of Canada, and Kinectrics.

NAC International has announced that it has received certification from the Nuclear Regulatory Commission for its new high-capacity Volunteer packaging system for transporting nonfissile or fissile-exempt radioactive materials.

As part of its Test Bed Initiative (TBI) demonstration project, the Department of Energy’s Office of Environmental Management completed two shipments of treated, low-activity tank waste from the Hanford Site near Richland, Wash. The approximately 2,000 gallons of TBI waste will be solidified in grout and permanently disposed of at Waste Control Specialists’ (WCS) federal disposal facility in Andrews County, Texas, and at EnergySolutions’ disposal facility in Clive, Utah.

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.

An agreement signed by the state of Idaho and the U.S. Department of Energy will open the way for a single cask of high-burnup spent nuclear fuel to be shipped from Dominion Energy’s North Anna nuclear power plant in Virgina to Idaho National Laboratory for research purposes.

Utah-based EnergySolutions has announced it has been awarded two contracts worth a combined $84.6 million from the U.S. Navy to support waste management operations across multiple Naval Nuclear Propulsion Program sites. According to the company, the indefinite-delivery, indefinite-quantity contracts will enable the secure transportation, receipt, processing, recycling and reduction, and disposal of nuclear materials from key naval sites nationwide.

Tokyo Electric Power Company is scheduled this week to begin retrieving a second sample of nuclear fuel debris from Unit 2 of Japan’s damaged Fukushima Daiichi nuclear power plant. This second retrieval comes after TEPCO improved the telescopic device used to gather samples.

The Department of Energy has announced that workers at its Savannah River Site in South Carolina recently removed legacy uranium materials from the site’s HB Line as part of an effort to clear the facility of its inventory of legacy nuclear materials. The removed legacy uranium was originally produced by the Y-12 National Security Complex at Oak Ridge, Tenn.

While attendance at the 2025 Waste Management Conference was noticeably down this year due to the ongoing federal retrenchment, the conference, held March 9-13 in Phoenix, Ariz., still drew a healthy and diverse crowd of people working on the back end of the nuclear fuel cycle, both domestically and internationally.

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 government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

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 Idaho Environmental Coalition (IEC) has provided funding to 15 classrooms in southeastern Idaho to support local educators and encourage the next generation of workers to pursue technical careers, the Department of Energy’s Office of Environmental Management announced. The IEC, which is led by Amentum and includes North Wind Portage as a partner, was awarded a 10-year, $6.4 billion contract in 2021 to manage cleanup operation at the Idaho National Laboratory Site.

The International Atomic Energy Agency has announced that its experts have confirmed that the tritium concentration in the latest batch of water to be released from the Fukushima Daiichi nuclear power plant is far below Japan’s operational limit. Tokyo Electric Power Company (TEPCO) began discharging the treated and diluted water on March 12.

NorthStar Group Services has announced that it has closed on an agreement to acquire ownership of the Vallecitos Nuclear Center from GE Vernova and GE Hitachi Nuclear Energy for NorthStar's nuclear decontamination, decommissioning, and environmental site restoration.

A virtual meeting between representatives of the West Valley Demonstration Project (WVDP) in New York and the Oak Ridge Office of Environmental Management (OREM) in Tennessee was held recently to share lessons learned from the ongoing demolition of West Valley’s main plant process building.
