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.

The Optimized Segmentation process patented by Orano Decommissioning Services was successfully implemented for the first time at the Crystal River Unit 3 (CR-3) decommissioning project in Florida [1]. Using this approach, Orano was able to avoid the time- and resource-intensive process of packaging components into numerous standardized waste containers and significantly reduced the required segmentation activities.

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.

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 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.
