Last year, we proudly launched the inaugural Nuclear News 40 Under 40 list to shine a spotlight on the exceptional young professionals driving the nuclear sector forward as the nuclear community faces a dramatic generational shift. We weren’t sure how a second list would go over, but once again, our members resoundingly answered the call, confirming what we already knew: The nuclear community is bursting with vision, talent, and extraordinary dedication.

There has been a lot of discussion lately about reforming the Nuclear Regulatory Commission. But I want to be clear: When it comes to nuclear safety and security, there is no place for partisan politics. I support efforts to streamline regulatory processes, but the independence and integrity of the NRC must remain sacrosanct. If we are serious about expanding nuclear power and reclaiming our global leadership in nuclear technology, having a strong independent regulator is fundamental.

Right now, we’re on the edge of a global nuclear resurgence driven by rising demand from data centers, growing concerns about energy security, and the need to decarbonize industry.

Levinson early in his career and today.

As a member of the American Nuclear Society, I have been to many conferences. The International Conference on Probabilistic Safety Assessment and Analysis (PSA ’25), embedded in ANS Annual Meeting in Chicago in June, held special significance for me with the PSA ’25 opening plenary session recognizing the 50^th anniversary of the publication of WASH-1400, which helped define my career. Reflecting on that milestone sent me back to 1975, when I was just an undergraduate student studying nuclear engineering at Rensselaer Polytechnic Institute (RPI) in Troy, N.Y., focusing on my mechanics, fluids, and thermodynamic classes as well as my first set of nuclear engineering classes. At that time—and many times since—the question “Why nuclear engineering?” was raised.

Idaho National Laboratory is playing a key role in helping the U.S. Department of Energy meet near-­term needs by recovering HALEU from federal inventories, providing critical support to help lay the foundation for a future commercial HALEU supply chain. INL also supports coordination of broader DOE efforts, from material recovery at the Savannah River Site in South Carolina to commercial enrichment initiatives.

The Hallam nuclear power plant, about 25 miles southwest of Lincoln, Neb., was an important part of the Atomic Energy Commission’s Reactor Power Demonstration Program. But in the end, it operated for only 6,271 hours and generated about 192.5 million kilowatt-hours of electric power during its short, 15-month life.

With the months rolling by, the time is coming for the American Nuclear Society to hold its second annual conference of the year. The 2025 ANS Winter Conference & Expo, with a theme of “Building the Nuclear Century,” will take place November 9–12 in Washington, D.C., at the Washington Hilton.

At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

Here is a recap of recent industry happenings:

ADVANCED REACTOR MARKETPLACE

New international partnership to speed Xe-100 SMR deployment

X-energy, Amazon, Korea Hydro & Nuclear Power, and Doosan Enerbility have formed a strategic partnership to accelerate the deployment of X-energy’s Xe-100 small modular reactors and TRISO fuel in the United States to meet the power demands from data centers and AI. The partners will collaborate in reactor engineering design, supply-chain development, construction planning, investment strategies, long-term operations, and global opportunities for joint AI-nuclear deployment. The companies also plan to jointly mobilize as much as $50 billion in public and private investment to support advanced nuclear energy in the U.S.

While most big journeys begin with a clear objective, they rarely start with an exact knowledge of the route. When commissioning the Lewis and Clark expedition in 1803, President Thomas Jefferson didn’t provide specific “turn right at the big mountain” directions to the Corps of Discovery. He gave goal-oriented instructions: explore the Missouri River, find its source, search for a transcontinental water route to the Pacific, and build scientific and cultural knowledge along the way.

Jefferson left it up to Lewis and Clark to turn his broad, geopolitically motivated guidance into gritty reality.

Similarly, U.S. nuclear policy has begun a journey toward closing the U.S. nuclear fuel cycle. There is a clear signal of support for recycling from the Trump administration, along with growing bipartisan excitement in Congress. Yet the precise path remains unclear.

Idaho National Laboratory under the Department of Energy–sponsored Microreactor Program recently conducted a comprehensive phenomena identification and ranking table (PIRT) exercise aimed at advancing heat pipe technology for microreactor applications.

ANS Executive Director/CEO Craig Piercy’s reflection on the 80th anniversary of the Trinity Test (Nuclear Newswire, July 16) was a thoughtful and fitting remembrance of the achievements and legacy of the World War II generation of nuclear pioneers. We also see legacy environmental cleanup as a vital next step as our industry launches what Secretary of Energy Chris Wright has defined as “Manhattan Project 2.0.”

When the Department of Energy’s Office of Legacy Management recently faced an operational challenge at the Rifle Disposal Site in Colorado, it took subject matter experts across a wide array of disciplines to tackle it.

When it comes to decision-making, public participation and community engagement are not the same thing. The structure and content of meetings to enable public participation in project decision-making can be staid, stale, and staged. The approach can be formulaic and reactionary: “We have a decision to make; we’ve narrowed down the alternatives … let’s prepare the scripts, posters, and presentations, gather our materials, book a room, coach the presenters on how to be succinct, identify people to staff the kiosks, contact the community members and regulatory staff we usually contact, and let’s have a public meeting! Once we get this over with, we can finally build our project, demolish that building, clean up this site, etc.” Not so fast.

The Idaho National Laboratory Site has long played an essential part in American nuclear reactor research and development activities. It is also a cornerstone of the Naval Nuclear Propulsion Program. The Naval Reactors Facility (NRF) on the INL Site, located in southeastern Idaho, was home to three historic land-based naval reactor prototypes—the Submarine 1st Generation Westinghouse (S1W) prototype, the Aircraft Carrier 1st Generation Westinghouse (A1W) prototype, and the Submarine 5th Generation General Electric (S5G) prototype—that facilitated critical training for naval personnel and testing that helped develop the U.S. Navy’s nuclear fleet.

Starting in 1966, the Western New York Nuclear Service Center (WNYNSC)—comprising 3,300 acres of land in the town of Ashford, N.Y.—was used for the commercial reprocessing of spent nuclear fuel. Reprocessing was conducted in the Main Plant Process Building (MPPB) until 1972 when commercial operations ceased and were never resumed. Now, 50 years later, modern 3D modeling technology is ensuring that the MPPB can be demolished in a safe and effective manner, minimizing risk to the environment and the workers.

Nuclear Restoration Services (NRS), a subsidiary of the U.K. Nuclear Decommissioning Authority (NDA), has adopted laser cutting as the primary technology for the removal of the reactor core of Dragon, a 20-MWt prototype high-temperature, helium-cooled, graphite-moderated reactor at Winfrith in Dorset, England. In addition, NRS is conducting trials to establish if laser cutting will be a viable technology for the decommissioning of the Trawsfynydd reactor, a first-generation Magnox reactor (CO₂ cooled, graphite moderated) situated in the Snowdonia National Park in Wales.

Earlier this year, Nuclear Waste Services, the radioactive waste management subsidiary of the U.K. Nuclear Decommissioning Authority, hosted a group of five teenagers for a week of exposure to real-world work environments at its facilities in Calderbridge, Cumbria. The students learned about career opportunities and leadership responsibilities at the company while they engaged with senior management and performed activities with several NWS teams, including employees in the environmental, waste characterization, cybersecurity, human resources, and geological disposal facility grants departments.

The theme of this year’s Winter Conference—already less than two months away—is “Building the Nuclear Century.” This focus reflects one of my chief goals during my presidency: streamlining the deployment of new power plants. However, I want to emphasize that this call to build extends far beyond a sole focus on new commercial reactors. As an industry, it’s critical that we keep momentum going across every area that supports the nuclear community.

So, while new reactor announcements are undeniably exciting and a logical benchmark to see the positive progress we’re making, we must continue to ensure that there is space to elevate, focus on, and celebrate crucial work in the fields of isotope production, waste management, public outreach, workforce training, and beyond. The call to build is a call to innovate and collaborate in every sector. It’s a call we need to follow.

As the only Department of Energy Office of Environmental Management–sponsored national lab, Savannah River National Laboratory has a history deeply rooted in environmental stewardship efforts such as nuclear material processing and disposition technologies. SRNL’s demonstrated expertise is now being leveraged to solve nuclear fuel supply -chain obstacles by providing a source of high-assay low-enriched uranium fuel for advanced reactors.

Nuclear power plant refueling outages are among the most complex phases in a plant’s operational cycle.¹ During these outages, tens of thousands of activities, including maintenance and surveillance, are conducted simultaneously within a short timeframe. Typically lasting three to four weeks, these operations involve large crews of contractors with diverse skill sets performing tasks ranging from testing and surveillance to maintenance. Outages may extend longer if major backfitting or modernization projects are planned. Consequently, plant outages are expensive, incurring significant operational costs, such as contractor labor and equipment, as well as the loss of generation while the plant is off line. This can easily cost a plant operator more than $1 million a day. Therefore, there is a constant need to mitigate the economic impact on plants by reducing the frequency, duration, and risks associated with these outages.^2,3
