BWX Technologies announced that the Department of Energy has approved Hanford Tank Waste Operations & Closure (H2C) to begin work under a contract valued at up to $45 billion to clean up tank waste at the Hanford Site near Richland, Wash. H2C is a limited liability company made up of BWXT Technical Services Group, Amentum Environment and Energy, and Fluor Federal Services.

If we needed more proof that this is a “nuclear week”—in the words of Energy Secretary Jennifer Granholm on Wednesday, as she announced small modular reactor funding while celebrating tech company investments in advanced reactors—the Department of Energy came through late yesterday when, just nine days after announcing six contracts for high-assay low-enriched uranium (HALEU) deconversion, it announced four contracts for HALEU enrichment services worth up to $2.7 billion. Those contracts are going to Centrus Energy’s American Centrifuge Operating subsidiary, General Matter, Orano Federal Services, and Urenco USA’s Louisiana Energy Services.

The Department of Energy is proposing to fully decommission the Submarine 5th Generation General Electric (S5G) prototype at the Naval Reactors Facility on the Idaho National Laboratory site. Along with the Environmental Protection Agency and the state of Idaho, the DOE has initiated a 30-day public comment period (ending November 14) on the planned end state for the facility and its defueled reactor vessel.

Yesterday morning as Amazon, X-energy, Energy Northwest, and Dominion Energy were sharing a spotlight celebrating their investment in X-energy’s high-temperature gas-cooled reactor technology, the Department of Energy opened up the application process for up to $900 million in cost-shared funding to support the initial domestic deployment of a different type of reactor—light water reactors generating about 300 MWe that the DOE calls Gen III+ small modular reactors.

Oklo Inc. announced yesterday that a safety design report for the Aurora fuel fabrication facility the company plans to build at Idaho National Laboratory has the approval of the Department of Energy. At the facility, Oklo plans to use high-assay low-enriched uranium (HALEU) that has been recovered from used Experimental Breeder Reactor-II fuel to produce fuel for its first planned microreactor—dubbed Aurora—which is also set for deployment at INL.

On October 8, the Department of Energy’s Idaho Operations Office released the draft environmental assessment (EA) Demonstration of Microreactor Experiment (DOME) Test Bed Operations. The draft EA assesses the potential environmental impacts of plans to use the containment dome of the former Experimental Breeder Reactor-II at Idaho National Laboratory’s Materials and Fuels Complex (MFC) to test multiple TRISO-fueled advanced reactor designs on a micro scale.

The Department of Energy announced yesterday a total of $49 million in funding for 19 projects in the Foundational Fusion Materials, Nuclear Science, and Technology programs that span functional and structural materials R&D for heating technology, magnet technology, blankets, fuel cycle, and first wall research.

The Department of Energy announced contracts yesterday for six companies to perform high-assay low-enriched uranium (HALEU) deconversion and to transform enriched uranium hexafluoride (UF₆) to other chemical forms, including metal or oxide, for storage before it is fabricated into fuel for advanced reactors. It amounts to a first round of contracting. “These contracts will allow selected companies to bid on work for deconversion services,” according to the DOE’s announcement, “creating strong competition and allowing DOE to select the best fit for future work.”

The Pathways to Commercial Liftoff: Advanced Nuclear report that was released in March 2023 by the Department of Energy called for five to 10 signed reactor contracts for at least one reactor design by 2025. Now, 18 months have passed, and despite the word “resurgence” in media reports on the U.S. nuclear power industry, 2025 is fast approaching with no contracts signed.

The Government Accountability Office has recommended that the Department of Energy put a hold on construction of its High-Level Waste Facility at the Hanford Site near Richland, Wash. The GAO said design and construction of the facility, part of Hanford’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, should be paused until several actions are taken, including considering other alternatives for managing the site’s high-level radioactive liquid waste.

President Biden has announced the appointment of six new members to the Nuclear Waste Technical Review Board, an independent federal agency that evaluates the technical and scientific validity of the Department of Energy’s activities related to managing and disposing of high-level radioactive waste and spent nuclear fuel.

By combining two techniques, analytical chemists at Oak Ridge National Laboratory have for the first time simultaneously detected fluorine and different uranium isotopes in a single particle. Quickly detecting both elements together may help International Atomic Energy Agency inspectors determine if and when undisclosed enrichment has taken place. The findings, published in the Journal of the American Chemical Society, “push the limit” of how fast single particles can be characterized in terms of their chemical, elemental, and isotopic compositions, according to a September 26 news release from ORNL.

With a $1.52 billion loan from the Department of Energy and $1.3 billion in grants to rural electric cooperatives near the plant, the ambitious plans to restart Michigan’s Palisades nuclear plant next fall are moving ahead.

The Department of Energy’s Office of Nuclear Energy has awarded 19 experimental proposals access to Nuclear Science User Facilities (NSUF) under the 2024 “third call” for Rapid Turnaround Experiment (RTE) projects. In total, the awards are valued at about $1 million and were granted to 19 principal investigators from 11 institutions, including universities and industry researchers.

The Department of Energy’s Office of Nuclear Energy announced on September 24 four new GAIN vouchers. GAIN—the Gateway for Accelerated Innovation in Nuclear—selected four companies to receive vouchers to advance microreactor technologies, identify potential sites capable of hosting a nuclear-powered data center, and prevent corrosion in molten salt reactors.

Hours before the Senate Committee on Environment and Natural Resources (ENR) opened a scheduled September 19 hearing on fusion energy technology development, CNN published an article titled “The US led on nuclear fusion for decades. Now China is in a position to win the race.” The article was entered into the hearing record, but senators had already gotten the message.

Regardless of who is sitting in the Oval Office next year, the Department of Energy’s Office of Environmental Management needs to take a close look at itself and “launch a comprehensive review of all aspects of the EM program,” according to a new report from the Energy Communities Alliance, which represents communities adjacent to or near DOE nuclear cleanup sites.

The 18-page ECA transition paper, Ensuring Long-Term Success: Recommendations for the Next Administration on the U.S. Department of Energy’s Environmental Management Mission, calls on the next administration to “take a fundamental look” at DOE-EM’s entire cleanup effort, including both sites that are active and those where work has been completed. How DOE-EM integrates with other DOE programs, including the National Nuclear Security Administration and the offices of Nuclear Energy, Science, and Legacy Management, should also be examined, according to the paper.

Westinghouse Electric Company has completed the front-end engineering and experiment design (FEEED) for a prototype microreactor at Idaho National Laboratory, the Department of Energy recently announced. The one-fifth scale version of eVinci, Westinghouse’s 5-MWe sodium-cooled heat pipe design, is one of three reactors that could be tested at the National Reactor Innovation Center’s (NRIC) DOME test bed “as early as 2026,” the DOE said.

Juno Beach, Fla.–based NextEra Energy Resources Development has been selected to enter realty negotiations for a large-scale solar electricity generation project at the DOE’s Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico as part of the department’s Cleanup to Clean Energy initiative.

Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.
