As interest and investment grows around AI applications in nuclear power plants, there remains a gap in standardized benchmarks that can quantitatively compare and measure the quality and reliability of new products.

Nuclear-tailored AI developer Atomic Canyon is moving to fill that gap by entering into a new strategic partnership with Idaho National Laboratory to develop and release the “first comprehensive benchmark suite for evaluating retrieval-augmented generation (RAG) and large language models (LLMs) in nuclear applications.”

Nuclearn, the nuclear AI start-up cofounded by Bradely Fox, one of Nuclear News’s 40 Under 40 honorees for 2024, announced it has raised $10.5 million in Series A funding to accelerate product development and market expansion of its AI platform for nuclear plant operations.

Rhoades

Mudrick

Longtime nuclear industry executive Chris Mudrick has been named the new chief nuclear officer at Constellation Energy, effective September 29. He will take over the position from Dave Rhoades, who is retiring from the role.

History: Mudrick has been Constellation’s senior vice president of generation growth since December 2024, a position that marked his return to the company after serving as executive vice president and CNO at Bruce Power in Ontario, Canada, for more than four years. Prior to joining Bruce Power, Mudrick was at Constellation/Exelon for more than 32 years, ending his time there as senior vice president of operations–East and chief operating officer. He began his career with the company as a nuclear power plant operator in Pennsylvania in 1987.

Constellation has reported that its employees were joined by hundreds of community members and labor leaders on August 26 at the Clinton Clean Energy Center to celebrate a power purchase agreement between Constellation and Meta that supports the relicensing, continued operation, and expansion of Clinton for another two decades. The rally was held at the plant site, located in rural DeWitt County, Ill.

Energy Secretary Chris Wright will attend the opening of the Advanced Manufacturing Collaborative in Aiken, S.C., on August 7. Wright will deliver remarks and join Savannah River National Laboratory leadership and partners for a ribbon-cutting ceremony.

The United States has tight new deadlines—18 months, max—for licensing commercial reactor designs. The Department of Energy is marshaling the nuclear expertise and high-performance computing assets of its national laboratories, in partnership with private tech companies, to develop generative AI tools and large-scale simulations that could help get nuclear reactor designs through the Nuclear Regulatory Commission’s licensing process—or the DOE’s own reactor pilot program. “Accelerate” and “streamline” are the verbs of choice in recent announcements from Oak Ridge National Laboratory and Idaho National Laboratory, as they describe plans with Atomic Canyon, Microsoft, and Amazon.

At the end of his July 15 speech at the inaugural Pennsylvania Energy and Innovation Summit, President Trump promised that “a lot more [was] going to be announced in the coming week” for the energy and AI sectors.

The Idaho National Laboratory has announced that it will collaborate with Microsoft on the use of artificial intelligence technologies to streamline the nuclear permitting and licensing application process. Using Microsoft’s Azure cloud computing platform, INL will generate the engineering and safety analysis reports that are required to be submitted for construction permits and operating licenses for nuclear power plants.

Representatives across all levels of Pennsylvania government convened at Carnegie Mellon University on July 15 with investors and key leaders in the energy community at the behest of Sen. Dave McCormick (R., Pa.).

A recent article in the Chicago Tribune explores the benefits and potential drawbacks of the 20-year power purchase agreement (PPA) signed by Constellation Energy and Meta last month.

Texas Tech University and Fermi America shared plans on June 26 to build “the world’s largest advanced energy and artificial intelligence campus” in Amarillo, Texas, near the Pantex nuclear weapons plant. Fermi America is a company cofounded by former Texas governor and energy secretary Rick Perry and his son, Griffin Perry, a cofounder and past senior advisor at Grey Rock Investment Partners. The announcement—a first press release from relative newcomer Fermi America—says the company “proudly answers President Donald J. Trump’s call to deliver global energy and AI dominance.”

SMR developer Arc Clean Technology has signed a memorandum of understanding with Deep Atomic to jointly explore deployment opportunities across North America.

Talen Energy Corporation and Amazon have signed an expanded power purchase agreement (PPA) whereby Talen agrees to supply electricity from its Susquehanna nuclear power plant for AI operations and other cloud technologies at Amazon Web Services’ data center campus next to the power plant.

This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.

Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.

or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

The first Advances in Nuclear Fuel Management (ANFM) conference in eight years is being held July 20–23, 2025, at the Sheraton Sand Key Resort in Clearwater Beach, Fla.

The Department of Energy’s Office of Nuclear Energy has posted a list of the advantages and challenges of using nuclear energy to power AI data centers, which some estimates suggest could consume as much as 12 percent of U.S. energy production by 2028. The DOE also posted a brief video on its YouTube channel to accompany the list.

Melbye

During an interview for Kitco News at the 2025 Prospectors & Developers Association of Canada (PDAC) Convention, held in Toronto in early March, the chief executive of British Columbia–based Uranium Royalty Corp. noted, “I’ve never seen a better narrative around nuclear power [and] uranium.”

CEO Scott Melbye, who is also executive vice president of Texas-based Uranium Energy Corp. and has 41 years of experience in the uranium sector, added that nuclear energy has gone from stagnation or decline to a point where it may double by 2040.

Imagine you’re constructing a bridge or designing an airplane, and everything appears flawless on the outside. However, microscopic flaws beneath the surface could weaken the entire structure over time.

These hidden defects can be difficult to detect with traditional inspection methods, but a new technology developed by scientists at the U.S. Department of Energy’s Argonne National Laboratory is changing that. Using artificial intelligence and advanced imaging techniques, researchers have developed a method to reveal these tiny flaws before they become critical problems.
