Designed for 40 years but built to last far longer, Switzerland’s nuclear power plants have all entered long-term operation. Yet age alone says little about safety or performance. Through continuous upgrades, strict regulatory oversight, and extensive aging management, the country’s reactors are being prepared for decades of continued operation, in line with international practice.

Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

On January 5, the Nuclear Waste Management Organization (NWMO), the not-for-profit organization responsible for managing Canada’s nuclear waste, announced that it has submitted to the Canadian government an initial project description for its proposed deep geologic repository to hold Canada’s spent nuclear fuel.

So much of what is happening in federal nuclear policy these days seems driven by a common approach popularized in the technology sector. Silicon Valley calls it “move fast and break things,” a phrase originally associated with Facebook’s early culture under Mark Zuckerberg. The idea emerged in the early 2000s as software companies discovered that rapid iteration, frequent experimentation, and a willingness to tolerate failure could dramatically accelerate innovation. This philosophy helped drive the growth of the social media, smartphones, cloud computing, and digital platforms that now underpin modern economic and social life.

Today, that mindset is also influencing federal nuclear policy. The Trump administration views accelerated nuclear deployment as part of a broader competition with China for technological and AI leadership. In that context, it seems willing to accept greater operational risk in pursuit of strategic advantage and long-term economic and security objectives.

I work in the analytical labs at one of Europe’s oldest and largest nuclear sites: Sellafield, in northwestern England. I spend my days at the fume hood front, pipette in one hand and radiation probe in the other (and dosimeter pinned to my chest, of course). Outside the lab, I have a second job: I moonlight as a writer and public speaker. My new popular science book—Going Nuclear: How the Atom Will Save the World—came out last summer, and it feels like my life has been running at full power ever since.

Argonne National Laboratory, located in Lemont, Ill., outside of Chicago, continues to develop a U.S. Department of Energy Packaging University Summer Institute by leveraging the laboratory’s educational resources and workforce development opportunities that support STEM (science, technology, engineering, and mathematics). The institute will be open to both professionals in the nuclear packaging field and highly qualified graduate university students who are recommended by their advisors.

In these challenging times of ever-increasing political polarization and strong differing personal opinions, there is hope that diverse points of view can converge to create solutions for difficult problems if we remain focused on the common good.

For us, the common interest is a solution for the broken U.S. program to dispose of the growing inventory of spent nuclear fuel and high-level radioactive waste from commercial nuclear energy. We strongly believe this is critical to support and enable our projected continuation and expansion of safe, reliable, clean, affordable nuclear power to support the needs of our rapidly evolving national and global societies.

The United States has a strong marketplace of ideas on future civil nuclear technology. President Trump wants to see 10 large reactors under construction by 2030 and has discussed making $80 billion available for that objective. Evolutionary small modular reactors based on light water reactor technology are on the market now, and the Tennessee Valley Authority expects a construction permit for a project at its Clinch River Site later this year.

Commonwealth Fusion Systems makes no small plans. The company wants to build a 400-MWe magnetic confinement fusion power plant called ARC near Richmond, Va., and begin operating it in the early 2030s. And the plans don’t end there. CFS wants to deploy “thousands” of fusion power plants capable of accelerating a global energy transition.

For the past several years, the University of North Carolina–Wilmington has hosted volunteer instructors from Wilmington-­based GE Vernova Hitachi Nuclear Energy who teach engineering courses and engage with students. This guest instructor program has grown under the guidance of Amy Craig Reamer, associate professor of practice and director of engineering in the UNCW College of Science and Engineering’s Department of Computer Science. Under her oversight, an informal but strong public-­private partnership has been established to the benefit of UNCW students and the wider Wilmington community.

I spent a fair amount of time over the holiday break pondering the makings of a good year for nuclear technology in 2026.

Last year was white-­hot. Between the fundamental upward shift in domestic electricity demand, the continuing proliferation of data center projects in all corners of the U.S., the increasingly voracious appetite of the financial markets for nuclear investment, and the Trump administration’s full-­throttle approach to nuclear policy, 2025 will likely be remembered as a significant, positive inflection point in the history of the harnessed atom.

I hope 2026 will be even better, but for it to be so, it will have to be different. It needs a seriousness about it, a scrape of the froth. Advanced nuclear energy technology is in a hardening phase at the moment, where the green shoots of innovation must now grow into robust commercial enterprises capable of scaling quickly and safely. Not everyone will succeed.

Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

As the energy sector faces mounting pressure to grow at an unprecedented pace while maintaining reliability and affordability, nuclear technology remains an essential component of the long-­term solution. Southern Company stands out among U.S. utilities for its proactive role in shaping these next-­generation systems—not just as a future customer, but as a hands-­on innovator.

When talking about growth in the nuclear sector, there can be a somewhat myopic focus on increasing capacity from year to year. Certainly, we all feel a degree of excitement when new projects are announced, and such announcements are undoubtedly a reflection of growth in the field, but it’s important to keep in mind that growth in nuclear has many metrics and takes many forms.

Nuclear growth—beyond megawatts—also takes the form of increasing international engagement. That engagement looks like newcomer countries building their nuclear sectors for the first time. It also looks like countries with established nuclear sectors deepening their connections and collaborations. This is one of the reasons I have been focused throughout my presidency on bringing more international members and organizations into the fold of the American Nuclear Society.

Nuclear is enjoying a bit of a resurgence. The momentum for reliable energy to support economic development around the country—specifically data centers and AI—remains strong, and strongly in favor of nuclear. And as feature coverage on the states in the January 2026 issue of Nuclear News made abundantly clear, many states now see nuclear as necessary to support rising electricity demand while maintaining a reliable grid and reaching decarbonization goals.

In early 1951, Los Alamos scientists Edward Teller and Stanislaw Ulam devised a breakthrough that would lead to the hydrogen bomb [1]. Their design gave the United States an initial advantage in the Cold War, though comparable progress was soon achieved independently in the Soviet Union and the United Kingdom.

Igunma

American Nuclear Society member Thompson Odion Igunma is a doctoral candidate in materials science and engineering at the University of Florida (UF) conducting research in collaboration with the Computational Mechanics and Materials Group at Idaho National Laboratory. His work focuses on advanced modeling of the complex interplay between molten salt corrosion, irradiation, and changes in alloy microstructure.

“I see molten salt reactors as a pivotal part of the next generation of nuclear energy,” Igunma said. “Their unique combination of safety, efficiency, and fuel flexibility makes them ideally suited to complement renewables in a low-carbon energy mix.”

In November, I flew to Paris, France, to speak at the World Nuclear Exposition. This wasn’t my first time at WNE, but it’s safe to say that the 2025 Expo was markedly different from years past. Excitement was palpable, and attendance was high—there were more than 25,000 attendees and 1,000 exhibitors. This enthusiasm reflects the growing nuclear momentum across Europe.

My opening remarks at the expo spotlighted the similar nuclear momentum on this side of the Atlantic, focusing on the recent strides made by both U.S. industry and government. I also highlighted the key challenges we still face: namely, workforce development, supply chains, fuel, and financing.

The past few years have seen a concerted effort from many U.S. states to encourage nuclear development. The momentum behind nuclear-friendly policies has grown considerably, with many states repealing moratoriums, courting nuclear developers and suppliers, and in some cases creating advisory groups and road maps to push deployment of new nuclear reactors.

Recently, a colleague related to me a conversation overheard at an industry forum in which ANS was referred to as a group of “academics” who were of limited use in expanding the workforce needed to deliver a nuclear resurgence.

While not new, this criticism still gets me hypertensive when I hear it. Many still see ANS as a bunch of academics and “labbies” disconnected from the day-to-day commercial nuclear race.

Yet, I also understand the charge is not entirely without foundation. Pop your head into a technical session at an ANS national conference, and you’re bound to hear academics presenting research that, to nontechnical ears, sounds esoteric.
