A nuclear engineer, former reactor operator, and nuclear navy educator earned U.S. Senate approval today to take a seat on the Nuclear Regulatory Commission.

Matthew Marzano was confirmed in a 50–45 vote in the Senate and steps into an existing five-year term that will expire June 30, 2028. He joins the five-member commission, which has been without a tiebreaker vote since June 2023, when Jeff Baran’s term expired.

Marzano brings more than a decade of industry experience both working in nuclear plants and advising energy policy on Capitol Hill.

Aalo Atomics and the Department of Energy announced yesterday that the company has worked with Battelle Energy Alliance and the DOE’s Idaho Operations Office to develop a plan—described as “provisional,” “potential,” and “tentative”—to grant Aalo a one-acre plot of land at Idaho National Laboratory site to build a new facility that would house an experimental reactor. Aalo hopes the reactor, dubbed Aalo-X, will help the company license and commercialize Aalo-1, a 10-MWe sodium-cooled reactor.

This month’s Nuclear News features our inaugural 40 Under 40 list of the brightest rising stars in the nuclear field.

The time has clearly come for this feature. The current resurgence of nuclear isn’t just a technological transformation; it’s also a changing of the guard. Consider this: For the first time in modern history, the American Nuclear Society has more members under the age of 40 than over the age of 60.

Of course, for as long as I can remember, the nuclear workforce has always been a bit of a double-humped demographic camel. Picture a nuclear workforce age chart and you will see two distinct peaks, or what a statistician might call a “bimodal distribution.” “Peak 1” is on the right and is centered over the Baby Boomer generation, many of whom entered the industry in its heyday of the 1960s and ’70s. These are the men and women who built the nuclear enterprise as we know it today.

Latta

To streamline the licensing requirements for nuclear fuel recycling facilities and help increase investment in nuclear energy in the United States, U.S. Reps. Bob Latta (R., Ohio) and Scott Peters (D., Calif.) have introduced the bipartisan Nuclear REFUEL Act in the House of Representatives.

The bill, introduced on December 6, would amend the definition of “production facility” in the Atomic Energy Act, clarifying that a reprocessing facility producing uranium-transuranic mixed fuel would be licensed only under 10 CFR Part 70. According to the lawmakers, this single-step licensing process would significantly streamline the licensing requirements for fuel recycling facilities.

Cambridge, Mass.–based fusion startup Acceleron Fusion announced that it has closed a $24 million Series A funding round co-led by Lowercarbon Capital and Collaborative Fund. According to Acceleron, the funding will fuel the company’s efforts to advance its low-temperature muon-catalyzed fusion technology.

A drone targeted and damaged an official vehicle of the International Atomic Energy Agency on December 10 as it traveled toward the front line in eastern Ukraine during a rotation of IAEA teams at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP). In a video message, IAEA director general Rafael Mariano Grossi condemned the strike as an “unacceptable” attack on IAEA staff working to prevent a nuclear accident during a military conflict.

The Department of Energy’s Idaho Cleanup Project (ICP) has improved transuranic waste operations to address aging waste containers being stored at the Advanced Mixed Waste Treatment Project (AMWTP) at the Idaho National Laboratory Site, the DOE’s Office of Environmental Management announced on December 10.

The Department of Energy announced yesterday the six companies that it has selected to supply low-enriched uranium (LEU) from new domestic enrichment sources under future contracts for up to 10 years. The contract recipients are: Centrus Energy’s American Centrifuge Operating, General Matter, Global Laser Enrichment (GLE), Laser Isotope Separation Technologies (LIS Technologies), Orano Federal Services, and Urenco USA’s Louisiana Energy Services.

The Department of Energy’s Savannah River Site in South Carolina recently joined in the nationwide celebration of the Department of Labor’s 10th annual National Apprenticeship Week, spotlighting the progress and diversity of its apprenticeship program that spans 27 occupations.

Several questions loom after federal and state elections: What does the future hold for nuclear science and technology? Will there be a shift in direction? How do we continue and expand our impact on energy and nonenergy initiatives? The American Nuclear Society is an organization of people, policies, and products. We innovate, educate, and facilitate collaboration. We advance the field, serving our members and engaging with communities. With every travel assignment, I have witnessed the collective passion and action of our members toward fuller participation and societal enhancement based on nuclear technology. The work is not done, but there is forward momentum.

We have never been a field that does not answer the call, and at this year’s Winter Conference and Expo, we explored the very apt theme “Now comes the hard part.”

Among the plenaries and technical sessions were panels about engaging and educating the next generation of nuclear professionals, the growth of nuclear engineering departments in higher education, a student design competition, and—as one might expect in November during an election year—keeping nuclear out of the political fray.

Tokamak Energy’s ST40 experimental fusion facility will receive a $52 million upgrade under a joint public-private effort with the U.S. Department of Energy and the U.K. Department of Energy Security and Net Zero (DESNZ) aimed at advancing the fusion science and technology needed to deliver a future pilot plant.

The Nuclear Regulatory Commission is asking for public feedback on the environmental report for a subsequent license renewal (SLR) request from Dominion Energy, the owners of V.C. Summer nuclear power plant in South Carolina.

Results from a recent Australian public opinion survey indicate that in Australia, women are much less likely than men to support nuclear energy. The findings of the survey, conducted by market research firm DemosAu on behalf of the Australian Conservation Foundation, somewhat reflect the findings about gender differences regarding nuclear energy in the United States—though the Australian gender split is much wider.

Serbia’s National Assembly has approved legislation that overturns the nation’s decades-old moratorium on nuclear power plants as the nation looks to reduce pollution.

Minister of mining and energy Dubravka Đedović Handanović posted on social media after the November 27 vote, “History has been written today. Many will inherit what has been done today!”

TitletownTech, a venture capital firm formed out of a partnership between Microsoft and the Green Bay Packers, has invested in Realta Fusion, a private fusion startup company that was spun out of an ARPA-E-funded fusion project at the University of Wisconsin–Madison in 2022. Realta is developing modular, compact, magnetic mirror fusion energy generators as an economic, zero-carbon solution to power AI-driven infrastructure and other industrial applications. TitletownTech did not disclose the details of its investment.

Jeffrey King

In August, the College of Engineering at Tennessee Technological University welcomed ANS member Jeffrey C. King as the founding director of its new nuclear engineering program. King, a leading force within the American Nuclear Society and a space enthusiast, is tasked with developing a new Department of Nuclear Engineering at Tennessee Tech after a more than 20-year absence of such a program at the university.

King comes to Tennessee Tech from the Colorado School of Mines, where he had been a professor of metallurgical and materials engineering for 15 years, leading the development of the nuclear science and engineering program and serving as director of the Nuclear Science and Engineering Research Center.

Since its inception in 2020, World Nuclear Energy Day has grown in awareness each year. The day is celebrated annually on December 2.

This year on December 2, the U.S. Senate passed a resolution for World Nuclear Energy Day, celebrating the peaceful development of nuclear energy technology and underscoring the vital role of nuclear power in strengthening the U.S. economy and supporting a reliable energy grid worldwide.

Schlender

Michael Schlender, former deputy director at Pacific Northwest National Laboratory, is joining Longenecker & Associates’ corporate advisory board, effective in January.

About Schlender: He has more than 30 years of experience in the U.S. national laboratory complex, including serving in senior leadership roles at PNNL and Brookhaven National Laboratory.

He is also the recipient of the secretary of energy’s Exceptional Service Award for his service to the Department of Energy, advancing excellence in operations across the national laboratory system.

Schlender holds a bachelor’s degree in chemistry and biochemistry from Eastern Washington University, and a master’s degree in chemistry from Western Washington University.

Here is a recap of industry happenings from the recent past:

ADVANCED REACTOR MARKETPLACE

Partnership formed for Idaho microreactors

Aalo Atomics has partnered with Idaho Falls Power to focus on the deployment of seven Aalo-1 microreactors that would provide a total of 75 MWe of power. The sodium-cooled microreactors—each with a 10-MWe capacity—are to be built at Aalo Atomics’ new headquarters and manufacturing facility in Austin, Texas. The reactor’s safety system, incorporating uranium zirconium hydride fuel, is designed to automatically shut down the reactor should it overheat. Aalo Atomics, which is currently constructing an Aalo-0 nonnuclear test reactor in Austin, intends to build an Aalo-X experimental reactor at Idaho National Laboratory before shifting to the Aalo-1 commercial unit. The Aalo-1 is not expected to come on line before 2030.
