The Nuclear Regulatory Commission announced that it has received the first portion of a construction permit application from Oklo subsidiary Atomic Alchemy that requests permission to build four nonpower reactors for a radioisotope production facility at Idaho National Laboratory. The submission is now available for public inspection on the NRC website.
The U.S. nuclear industry is standing at its most volatile regulatory moment yet—one that will shape the trajectory and the safety of the industry for decades to come. Recent judicial, legislative, and executive actions are rewriting the rules governing the licensing and regulation of nuclear power reactors. Although these changes are intended to promote and accelerate the deployment of new nuclear energy technologies, the collision of multiple legal shifts—occurring simultaneously and intersecting with profound technological uncertainties—is overwhelming the Nuclear Regulatory Commission and threatening to destabilize investor and industry expectations.
As President Trump hosted Saudi Crown Prince Mohammed bin Salman at the White House on November 19, Energy Secretary Chris Wright confirmed that the United States and Saudi Arabia have signed a “historic” deal on cooperation in the civilian nuclear energy sector. The “Joint Declaration on the Completion of Negotiations on Civil Nuclear Cooperation” is seen as an important part to strengthen U.S. influence in the Gulf region to counter the influence of Iran, Russia, and China.
Workers have begun demolishing the massive X-333 Process Building at the Portsmouth Site in Ohio, the Department of Energy’s Office of Environmental Management announced.

The Department of Energy announced on November 18 that it has closed on a $1 billion loan through its Loan Programs Office to Constellation to aid in financing the restart of the 835-MWe Crane Clean Energy Center, formerly Three Mile Island-1.
AI for energy, and energy for AI: that is the new refrain. But can nuclear power plants be deployed at the pace needed for substantial and timely contributions to the energy infrastructure? For Westinghouse, delivering its AP1000 on time and on budget in the United States is a challenge not yet accomplished, while newcomers like Aalo Atomics are turning to AI to speed design, permitting, and construction.

This question is the one that we ask and answer every day. University faculty are uniquely positioned to bridge the gap between generative AI capabilities and the nuclear industry’s evolving energy challenges. By leveraging our expertise in research, education, and collaboration, faculty can drive advancements in nuclear technology, cultivate a skilled workforce, and foster public and industry support.
There is no industry without a skilled, well-educated workforce. At Texas A&M’s Department of Nuclear Engineering, we nurture our students through a very comprehensive and rigorous nuclear engineering program, which has a critical impact on the nuclear industry as those students enter the workforce. As nuclear industry demands grow, so too our student population is growing. We are approaching 200 graduate students and 400 undergraduate students in our programs.
As part of the Janus Program, announced in October, the Department of the Army is seeking potential commercial vendors to build microreactor power plants at nine military installations that are under consideration.
Nieh
Earlier today, the U.S. Senate officially confirmed Ho Nieh in a 66–32 vote to serve as a commissioner on the U.S. Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029. All present Republicans, alongside 15 Democrats and one Independent, cast their votes in favor of Nieh, who was nominated by President Trump in July and fills the seat left vacant following the dismissal of former commissioner Christopher Hanson.
NRC details: The commission leading the NRC now comprises four members. Nieh joins Chair David Wright and commissioners Bradley Crowell and Matthew Marzano. One spot remains unfilled after the resignation of Annie Caputo in July. President Trump nominated Douglas Weaver earlier this month to fill Caputo’s seat.
A new type of material has been demonstrated to greatly enhance the ability to recover uranium from seawater, according to a study published recently in Sustainable Carbon Materials. The research, which could lead to a new way of obtaining uranium for nuclear reactor fuel, was conducted by scientists from Weifang University and North China Electric Power University.
Due to the days lost to the government shutdown, the Nuclear Regulatory Commission has extended the public comment period for a draft environmental impact statement for the TX-1 advanced nuclear fuel fabrication facility being built in Oak Ridge, Tenn.
Utah Gov. Spencer Cox joined Brigham City Mayor D. J. Bott this week to announce a new partnership among the state, city, Hi Tech Solutions, and Holtec International. The partnership plans to develop a “full-scale nuclear energy ecosystem” based in Brigham City that will feature advanced manufacturing, workforce development, and Holtec’s SMR-300.
Valar Atomics has announced that its Nova Core achieved zero-power criticality on November 17 at Los Alamos National Laboratory’s National Criticality Experiments Research Center (NCERC) at the Nevada National Security Site.

As 2025 winds down, it seems nuclear energy in the U.S. is now well on its way toward a renaissance, or resurgence, or whatever optimistic term you may use in your daily conversations.
New reactor designs, projects, and partnerships are being announced on a near-weekly basis; valuations of publicly traded nuclear companies are hovering near all-time highs; and AI’s thirst for reliable, clean electricity remains largely unquenched. The overall investment climate for nuclear energy has thawed dramatically. These days, it seems everyone from big Wall Street banks to individual investors is trying to get a piece of the nuclear action.
It’s the perfect time to talk about failure.
Yes, I know “nuclear failure” is not a topic on which we in the nuclear community like to dwell. For those of a certain age, it brings back bad memories of events beyond our control that shifted the trajectory of companies, careers, and lives for decades.
Mobley
American Nuclear Society member John Mobley IV recently donated some historical nuclear artifacts and memorabilia to the Department of Nuclear Engineering and Radiological Sciences (NERS) at the University of Michigan.
Mobley is a nuclear engineering education researcher at the University of Michigan. Among his roles at ANS, he is currently the secretary of Young Members Group; the vice chair of the Education, Training and Workforce Development Division; and the vice chair of Student Sections Committee.
He said he chose to donate part of his collection to NERS because the University of Michigan is broadly committed to nuclear outreach at the local, state, and federal levels. The university is home of the first ANS Student Section, which turned 70 this year.
