Transitioning in nuclear from the U.S. Navy to the commercial industry was always a goal for me, but stepping directly into a fully digital control room was a paradigm shift. Moving from the tactile, analog world of my military background to the data-rich environment of modern advanced reactors was jarring. Digital systems offer an unprecedented wealth of information, but unlocking that potential requires a fundamental shift in how we approach testing, commissioning, and startup.

Commissioning analog plants meant physical verification, such as lifting leads, injecting signals, and manually tweaking potentiometers to calibrate gains and offsets. Digital instrumentation and control (I&C) completely redefines this landscape. Today, nearly all plant data are available at our fingertips, but this brings the challenge of filtering an immense amount of data and system alarms. Troubleshooting has largely migrated from the field and into software, following digital signals from operator inputs to field devices.

New frontiers

There may have been no more fitting place to gather for a conversation about the future of nuclear energy than Colorado.

For the nuclear community, Colorado carries a special resonance. About an hour north of Denver stands Fort St. Vrain. Today, it is a garden-variety natural gas power plant. But there was a time it was an ambitious nuclear reactor—a high-temperature gas reactor with helium coolant and a uranium-thorium fuel cycle. It was ahead of its time in many ways and imperfect in execution, but unmistakably part of the long story of nuclear innovation in America.

Colorado is a state shaped by frontiers. We, too, are standing at a frontier, which brings me to this year’s conference theme: “Net Out, Power Up.” We chose this theme to reflect the complementary challenges facing two parts of our community. “Net Out” reflects fusion’s challenge: proving you can get more energy out than you put in. “Power Up” reflects fission’s challenge: scaling advanced nuclear technologies quickly enough to meet rising demand.

In transition: Commercializing fusion power

Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.

Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

Meeting the moment

July 23, 2026, 10:10AMNuclear NewsMark Peters

It is both an honor and a privilege to begin my term as president of the American Nuclear Society. I am deeply grateful for the trust placed in me by the membership, and I look forward to serving this remarkable Society over the coming year.

I would also like to recognize the leadership of my predecessor, Hash Hashemian, as well as the dedication of ANS CEO Craig Piercy, our staff, and countless volunteers. ANS succeeds because people choose to contribute their time, expertise, and energy in service of a mission larger than themselves.

We begin this year at a moment of tremendous opportunity for nuclear science and technology. Around the world, there is growing recognition that nuclear energy and nuclear technologies are essential to addressing some of society’s most pressing challenges. At the same time, advances in areas ranging from medical isotopes and fusion to space nuclear systems and advanced reactors are creating new possibilities for innovation and impact.

As human factors specialists working at the intersection of human performance and nuclear operations, we are witnessing one of the nuclear sector’s most significant transitions in decades. The emergence of small modular reactors, microreactors, and other advanced designs is reshaping the industry’s landscape. Digital instrumentation and controls, passive safety systems, and increased automation are creating opportunities for greater safety margins and more flexible operation. These same features also fundamentally redefine what it means to “operate” a nuclear plant. Interactions among human roles, automation, and passive systems shape how people maintain awareness, exercise judgment, and intervene when necessary. These developments affect both operational realities and the regulatory foundations on which nuclear safety is built.

Nuclear is ready now

I don’t think we’ve ever had a busier year in the Office of Nuclear Energy, and it’s probably been decades since we’ve had this much momentum within the overall U.S. nuclear industry.

President Trump and Energy Secretary Wright have made very clear the important role that nuclear must play in meeting our energy needs, and that’s well demonstrated by the four executive orders that the president signed [more than] 375 days ago. In nuclear, we’re now talking about days, not years.

Those EOs set a goal for the United States to quadruple the amount of nuclear that we have. We need to go from the 94 reactors that we have operating right now, which generate roughly 100 gigawatts of electricity, to 400 gigawatts by 2050.

Summer at the American Nuclear Society carries with it a sense of renewed momentum as the incoming president takes office and starts making plans for the year ahead. This has been particularly true in the last few years, as nuclear energy moves into a new era marked by broader public interest, stronger policy support, and a growing sense of possibility across the field. Mark Peters, the Society’s 72nd president, shares that optimism—and he is focused on turning it into results.

Fostering a nuclear landscape to power America's next 250 years

On top of the many celebrations planned for America’s 250th birthday, the Trump administration wants to mark a nuclear milestone as well: achieving criticality for at least three advanced reactor concepts by July 4, 2026.

But this wouldn’t really be a milestone. On a day of fireworks nationwide, it would just be more noise.

Third Way has celebrated the nuclear sector’s progress during the Trump administration and supported the goal of 400 GW of nuclear energy by 2050. Additionally, we think all five commissioners on the Nuclear Regulatory Commission have prioritized safety in new designs and defended an understaffed agency under pressure to bypass important processes.

Design, deliver, repeat: A formula for success in nuclear’s next era

Conditions for nuclear energy haven’t looked this favorable in a generation. Policy support is building, public support has risen, and demand for reliable power continues to outpace what other sources can provide. Whether the industry can successfully capitalize on this moment will come down to how well it executes.

The proven truth is that execution success is largely determined before construction ever starts—by ensuring design constructability, shaping the project’s execution plan, aligning design and delivery, and establishing the systems needed to control cost and schedule. Many large energy projects have faltered for lack of these engineering, procurement, and construction (EPC) fundamentals.

In 2019, a familiar landmark at Idaho National Laboratory was scheduled for demolition. Though striking for both its physical presence and its significance to nuclear history, the containment dome that once housed Experimental Breeder Reactor-II sat unused—that is, until INL realized its potential as a reactor testing facility.

Recently, I spent an afternoon at Kairos Power’s Hermes construction site in Oak Ridge, Tenn. What I saw there was not a rendering, not a licensing presentation, not another panel about the future of advanced nuclear. I saw dozens of pilings built to NQA-1 standards. I saw seismic isolators ready for installation. I saw heavy equipment moving dirt and crews preparing concrete and steel.

I also saw a company doing genuinely innovative work with precast concrete techniques that could materially improve how we construct reactors in the future. None of it looked theoretical. It looked industrial.

Evergy’s Wolf Creek Generating Station, near Burlington, is the only nuclear power plant in Kansas. In addition to generating 20 percent of the state’s electricity—enough to power 800,000 homes—it has been generating educational opportunities by providing internships and co-op employment to nuclear engineering students from universities around the Midwest for 35 years.

The drive to Kairos Power’s reactor demonstration site in Oak Ridge, Tenn., is not only scenic—it’s historic. Nearly 85 years ago, roughly 30,000 construction workers transformed orchards and farmland into a key Manhattan Project site. Depending on your route, you may pass by one of the three gatehouses that were once military checkpoints controlling access to Atomic Energy Commission production facilities.

Investing in what comes next

The 2026 ANS Annual Conference, “Net Out and Power Up,” brought the nuclear community together in Denver at the end of May. Over four days at the Sheraton Denver, we heard from exceptional speakers on the most consequential questions facing our field; how fusion and fission can complement each other, how to meet surging electricity demand, and what it takes to sustain American nuclear leadership. The embedded topicals on nuclear fuels and materials and on fusion energy added real technical depth. It was exactly the kind of gathering that reminds us why this community is so remarkable.

That energy and commitment is precisely what I want to channel as I close out my term as president of the American Nuclear Society. Because sustaining it year after year, conference after conference, requires more than enthusiasm. It requires investment.

Here is a recap of recent industry happenings:

ADVANCED REACTOR MARKETPLACE

Fluor gets X-energy contract for Dow’s Seadrift project

Fluor Corporation has signed a contract to support X-energy’s planned small modular reactor project at Dow’s UCC Seadrift Operations facility in southern Texas. Fluor’s role will initially involve delivery of front-end loading stage 2 services, including project definition, strategic planning, feasibility assessment, cost control, and risk mitigation. X-energy plans to deploy four 80-MW SMRs to replace old infrastructure and supply electricity and industrial steam for the Seadrift facility, which produces materials for such applications as food packaging, footwear, wire and cable insulation, solar cell components, and medical and pharmaceutical packaging. X-energy submitted a construction permit application for the project, which is supported by the Department of Energy’s Advanced Reactor Demonstration Program, to the Nuclear Regulatory Commission in March 2025.

Deploying nuclear power: Financing, risk, and execution in the current market environment

May 29, 2026, 3:09PMNuclear NewsRyan Nielson

Nielson

The renewed global interest in nuclear power is often framed as a policy story driven by decarbonization goals, energy security concerns, and surging electricity demand from digital infrastructure and electrification. While these forces are real and durable, they materially understate the challenge at hand. The practical constraint on nuclear deployment today is not strategic will, but execution. Specifically, the challenge lies in how nuclear projects are financed, how risk is allocated, and how investors assess credibility in a sector defined by long timelines and asymmetric downside risk.

Kindergarten classrooms, the control rooms of newly completed reactors, and the meeting rooms of ANS local sections all have one thing in common: they are only made useful once they are filled with hardworking and passionate people.

In March, I had the privilege of engaging with some of the people in these spaces: the students, regulators, lawmakers, and fellow scientists from across several states who are working to build up the nuclear industry every day. These interactions served as yet another reminder that people serve as the bedrock of our work to push nuclear energy forward.

The month began here in my home city of Oak Ridge, where I welcomed a group of kindergartners from Woodland Elementary School to tour both the headquarters of AMS and the Roane State Community College Nuclear Technology Lab.
