If there is any place that would be off-limits to AI, the control room of a nuclear power plant certainly sounds like one. The nuclear industry is historically cautious and risk averse—understandable given the possible catastrophic consequences of an accident or a mistake. Even well-trained managers struggle with the operational complexity of a nuclear reactor. It’s not the kind of setting that seems well suited to a powerful but error-prone new technology.
Reality tells a startlingly different story. A variety of companies have begun to offer AI solutions for nuclear power. This year, nearly the entire fleet of 94 U.S. nuclear reactors has been offered the chance to integrate AI into its operations, and most have taken it.
In August, California-based Atomic Canyon launched NIVA, the Nuclear Industry Virtual Assistant, which was developed in cooperation with nuclear industry groups. The assistant was pilot tested in nuclear plants run by Constellation Energy and is now available to the United States’ entire fleet of reactors. (Constellation declined to be interviewed for this story.) Meanwhile, the AI-for-nuclear startup Nuclearn says its products have gone to work with more than 65 U.S. partners, a total that includes many traditionals plants but also an integration with NuScale Power Corporation that is working toward advanced small nuclear reactors. Microsoft and Nvidia have collaborated on a project to apply AI toward optimizing “the entire lifecycle of a nuclear plant, spanning site permitting, design, construction, and continuous operations.”
The reason for the rapid adoption, according to Nuclearn CFO and cofounder Jerrold Vincent, is twofold. First, the technology companies banking their futures on AI are also keen on a revival of nuclear power to provide the electricity for all those data centers. Vincent says AI is also ideal for addressing some of the nuclear industry’s most pressing problems. Many of the things that make reactors so difficult to operate–intricate regulations, along with complex systems for management and maintenance–are exactly the kinds of tasks that AI is good at. The industry is staggering to deal with aging hardware and an aging workforce. If it is going to survive, and have a real shot at a nuclear revival, it will need help from machine intelligence, Vincent says.
“There’s this huge growth in demand from advanced reactor developers and in new nuclear,” Vincent adds. “But the existing workforce has spread really thin. So most of the time when we’re coming into a customer, [they're saying,] ‘I’ve had jobs open and I can’t fill these positions. We need to do the things required by regulation. How the heck are we going to do it?’”
AI Streamlines Nuclear Documentation
Right now, the principal output of a nuclear reactor (aside from electricity) is paperwork. Nuclear plants produce piles of documentation to demonstrate regulatory compliance and to record how they respond to any potential problem, from a crack in the sidewalk to a fault in the reactor.
“Every engineering decision has to be evaluated, independently verified, and checked,” Vincent says. Nuclearn’s AI products help plants search through large repositories of data more efficiently to more quickly file paperwork with the federal government or figure out how a particular problem was solved in the past. “If you think of it as ChatGPT for nuclear,” he says, “it’s actually not a bad place to start.”
Rob Austin, the Electric Power Research Institute’s leader for the NIVA project, says the project started a year ago when Constellation chairman Joseph Dominguez issued a challenge to the non-profit industry groups that act as storehouses of information about regulatory compliance, maintenance and repair, and mechanical history. He asked the groups to find a way to make that industry knowledge available with the convenience of a large language model like ChatGPT, Copilot, or Gemini, but at the same time keep it secure.
The task fell to Atomic Canyon, whose CEO Trey Lauderdale previously worked to integrate AI into healthcare, another conservative industry. Living and working downstream from Diablo Canyon, California’s last operating nuclear plant, he began to see how nuclear energy and AI could form a mutually beneficial relationship: A revival of nuclear power could help feed electricity to energy-hungry data centers, but only if AI could help the industry thrive again.

A major hurdle is public opinion of nuclear power, which soured decades ago after notorious accidents and worries about waste and only recently has begun to recover. But the resulting halt in construction of new nuclear plants has created another hurdle of its own: a loss of institutional knowledge, Lauderdale says. As the industry stalled in the U.S., fewer people entered careers as nuclear scientists or technicians. The result is a people problem. Nuclear power has a remarkably skilled but quickly shrinking workforce tasked with keeping old reactors online and possibly starting up new ones to meet surging demand for electricity.
“There is absolutely no way we as an industry will be able to have this nuclear resurgence or nuclear renaissance without augmenting the capacity of this knowledge-based workforce,” Lauderdale says.
For him, the answer is an AI that can smartly search the repository of data that the nuclear workforce has created over the decades. When Atomic Canyon won the NIVA contract in 2025, the first step was to download 53 million pages of publicly available data from the Nuclear Regulatory Commission to train the model on the operations, vernacular, and regulations particular to nuclear power. Lauderdale then struck a partnership with Oak Ridge National Laboratory to build the first nuclear-specific AI models.
“Technically, they’re sentence-embedding models,” Lauderdale says. “Fancy way of saying: we taught AI how to seek the nuclear language. Nuclear is almost like its own vernacular.” The goal is that today’s nuclear workers can ask questions about every aspect of plant operations, from filling out regulatory forms to procuring the right tools and materials, simply by writing a query and letting the AI sort through all of the accumulated institutional knowledge.
Unifying Nuclear Data for AI Searches
When Lauderdale began to work with Diablo Canyon on integrating AI into the nuclear industry, it became apparent that one bottleneck was simply getting decades’ worth of a nuclear plant’s documentation—procedures, best practices, safety recommendations—into an easily searchable format. Information across the industry was scattered and not standardized, which is why three of the biggest nonprofit entities in the industry (the Institute of Nuclear Power Operations, the Electrical Power Research Institute, and the Nuclear Energy Institute) moved in 2025 to create unified datasets, an idea that would birth the NIVA AI assistant developed at Atomic Canyon.
For example, EPRI’s Austin says, nuclear engineers might run into a problem with one of the house-sized, thousand-horsepower vertical pumps that circulate vast quantities of water used for cooling purposes. In their search for a solution, the workers have access to plenty of information. Too much information, perhaps. They can read through EPRI’s maintenance guides about those components. They can also call upon tens of thousands of incident reports stored with the Institute of Nuclear Power Operations about things that have gone wrong with pumps in the past. AI’s task is to synthesize all those reports to create a guide to the main failures that strike a pump, and, crucially, to show all its work so engineers can find the documentation it used to make its recommendations.
“I want to know all the other nuclear power plants that have that same part,” Lauderdale says. “Have any of them seen a similar issue? How did they fix it? What’s the troubleshooting look like? If you think about nuclear, we have a tremendous amount of information. The challenge is, how do you collectively gather knowledge from that information data set? And that’s what AI is really, really good at doing.”

Secrecy is a major hurdle to modernizing nuclear operations. AI systems that chiefly help with documentation and data search aren’t subject to the strictest rules, like they would be if they interacted with components that control the plant. But nuclear data itself is largely proprietary or protected by federal law.
Nuclearn offers only single-location solutions to deal with this, so that a plant’s data can never leave that site. NIVA can only search databases that already required plant-level security clearances, Austin says, so the same rules hold true for using the AI assistant to hunt through that deluge of data. Technology cannot wipe away these human barriers, but it does provide new incentives to find ways to share data more openly.
“The goal was to make decades of operating experience, hundreds of thousands literally of operating experience reports, tens of thousands of technical documents and a whole lot of information available for people to find, and do so in a way that’s going to be much more accessible and easy to use, but at the same time preserving data security and that critical information, keeping control over it,” Austin says. That’s exactly what NIVA does.
