Waste Management

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.

The Department of Energy’s Office of Environmental Management said that crews with the Oak Ridge Office of Environmental Management (OREM) and its cleanup contractor UCOR are preparing to demolish another deteriorating Manhattan Project–era building at the Y-12 National Security Complex at Oak Ridge, Tenn.

Nuclear energy produces about 9 percent of the world’s electricity and 19 percent of the electricity in the United States, which has 94 operating commercial nuclear reactors with a capacity of just under 97 gigawatts-electric. Each reactor replaces a portion of its nuclear fuel every 18 to 24 months. Once removed from the reactor, this spent (or used) nuclear fuel (SNF or UNF) is stored in a spent fuel pool (SFP) for a few years then transferred to dry storage.

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.

For over a decade, the DOE’s Hanford Field Office (HFO) has been working with national laboratories, universities, and glass industry experts to establish capabilities and generate data to increase the confidence in a successful startup and transition to full-time operations at the WTP.

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.

The cost to complete the cleanup of the Department of Energy’s Hanford Site in Washington state could cost as much as $589.4 billion, according to the 2025 Hanford Lifecycle Scope, Schedule, and Cost Report, which was released by the DOE on April 15. While that estimate is $44.2 billion lower than the DOE’s 2022 estimate of $640.6 billion, a separate, low-end estimate has since grown by more than 21 percent, to $364 billion.

The life cycle report, which the DOE is legally required to issue every three years under agreement with the U.S. Environmental Protection Agency and Washington State Department of Ecology (Ecology), summarizes the remaining work scope, schedule, and cost estimates for the nuclear site. For more than 40 years, Hanford’s reactors produced plutonium for America’s defense program.

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.

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.

Savannah River National Laboratory researchers are building on the laboratory’s legacy of using cutting-edge science to effectively immobilize nuclear waste in innovative ways. As part of the Center for Hierarchical Waste Form Materials, SRNL is leveraging its depth of experience in radiological waste management to explore new frontiers in the industry.

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.”
