A recent article on Australia’s ABC News website highlighted the work of undergraduate physics and engineering students at the University of New South Wales (UNSW) to design, build, and operate their own small nuclear fusion reactor. The ambitious work, known as the AtomCraft project, is being led by associate professor Patrick Burr with the objective of producing a student-built tokamak reactor by the end of 2026.

Australia-based HB-11 Energy and U.K.-based Tokamak Energy have partnered with UNSW for the project.

Research goals: The AtomCraft project has the following research goals for participating students, according to its website:

Our team aims [to] make the world’s first fusion reactor entirely designed, built, and operated by students. And [to] do so in 2 years. You will develop innovative solutions to engineering challenges across many engineering disciplines, work closely with industry partners, and be part a vibrant team of enthusiastic and dedicated people who want to push the boundaries of what is possible with fusion energy.

Radiant Industries announced on June 4 that the safety design strategy (SDS) for a test of its Kaleidos microreactor in the National Reactor Innovation Center’s DOME test bed at Idaho National Laboratory now has approval from the Department of Energy. Radiant hopes to test Kaleidos—a 1-MW high-temperature, gas-cooled reactor—by 2026 and then market portable commercial reactors to power remote locations and provide backup or primary power for critical applications in hospitals or for disaster relief.

Results of two new surveys have shed light on American public opinion regarding nuclear energy. The surveys, which were conducted with very different methods, offer generally encouraging news for the nuclear industry.

The groundbreaking brought together TerraPower leaders, government officials, Natrium project partners, industry advocates, and community supporters.

At the “Past Department of Energy Nuclear Energy Officials Roundtable” webinar on May 20, the American Nuclear Society gathered six past assistant secretaries for the Office of Nuclear Energy for a very special discussion. The group of stellar leaders, who have shaped the current state of innovation and growth around nuclear energy, shared insights from their time as NE-1 and their perspectives about where we must go from here.

Just one week after the White House Office of Science and Technology Policy hosted a summit on domestic nuclear deployment, they filled a room again on June 6 for a livestreamed event cohosted with the Department of Energy to announce a new DOE fusion energy strategy and new public-private partnership programs, and to hear directly from stakeholders—including scientists, private fusion companies, investors, and end users—during panel discussions on fusion science and technology progress and the path to fusion energy commercialization.

The Department of Energy will enter into lease negotiations with two solar energy developers for 400 megawatts of solar electricity generation within the Idaho National Laboratory site. Announced on June 5, the projects are the first proposed projects selected under the department’s Cleanup to Clean Energy initiative, an effort to repurpose parts of DOE-owned lands—portions of which were previously used in the nation’s nuclear weapons program—into sites of clean-energy generation, including for solar, geothermal, wind, and nuclear.

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) held another Community of Practice (CoP) on April 26. For this event, the committee welcomed Mory Diané of Oklo. RP3C chair N. Prasad Kadambi led with a brief introduction before Diané shared Oklo's risk-informed, performance-based (RIPB) approach to seismic design categorization and seismic siting characterization.

Power generation from nuclear fission as a clean and stable source of electricity has secured the interest of policymakers and industry leaders around the globe. Last fall, the United States spearheaded a pledge at COP28 to get countries to agree to triple nuclear capacity worldwide, and recently the members of the Group of 7 (G7) nations that currently use nuclear power have reaffirmed their pledges to invest in that power source to cut carbon emissions.

As of this writing, U.S. policymakers are trying to make good on that promise by passing legislation to support nuclear power, funding the domestic fuel supply chain, and working to pass the ADVANCE Act. On top of the support from Washington, D.C., power-hungry industries like data centers and chemical engineering are looking to secure stable, carbon-free power directly from power plants.

The board of governors for the International Atomic Energy Agency censured Iran this week for its failure to cooperate with access requests and materials needed to confirm that the Middle Eastern nation is adhering to nuclear safeguard obligations.

On August 23, 2011, at 1:51 p.m., I was standing next to Matt Milazzo, a former ANS Congressional Fellow, on the sidewalk of a high-traffic D.C. street. We were saying goodbye after a pleasant lunch. At that exact moment, a seismic wave from a 5.9 magnitude earthquake in Mineral, Va.—one that would be felt as far away as Canada and cause hundreds of millions of dollars in damage—rippled under my feet. Perhaps it felt too familiar, like a heavy truck passing by, or maybe the oscillation peaked just as I was turning to walk back to my office. Either way, I didn’t feel a thing. The largest East Coast earthquake in 100 years, and I missed it. Completely. It wasn’t until I saw the stunned faces of my colleagues and a few picture frames scattered on the floor of my office that I understood the gravity of the moment.

Today, as I wrap my head around the stunningly large amount of energy that will be required to support advanced data center and AI functions in the coming years, I get the same feeling—that something big and consequential has happened in my larger world and I have been slow to perceive the magnitude of it.

Xcimer Energy announced June 4 that it has raised $100 million in Series A financing for a new facility in Denver, Colo., that will host a prototype laser system with “the world’s largest nonlinear optical pulse compression system.” As a private fusion developer, Xcimer wants to “extend the proven science of inertial fusion to industrial scale” with the help of that laser system and “key technologies and innovations from multiple fields.”
