California Nuclear Power Plant Deploys Generative AI Safety System

America's first nuclear power plant to use artificial intelligence is, ironically, the last operational one in California.
As CalMatters reports, the Diablo Canyon power plant is slated to be decommissioned by the end of this decade. In the interim, the plant's owner, Pacific Gas & Electric (PG&E), claims that it's deploying its "Neutron Enterprise" tool — which will be the first nuclear plant in the nation to use AI — in a series of escalating stages.
Less than 18 months ago, Diablo Canyon was hurtling headlong toward a decommissioning that would have begun in 2024 and ended this year. In late 2023, however, the California Public Utility Commission voted to stay its execution for five years, kicking the can on the inevitable to 2029 and 2030, respectively.
Just under a year after that vote, PG&E announced that it was teaming up with a startup called Atomic Canyon, which was founded with the plant in mind and is also based in the coastal Central California town of San Luis Obispo. That partnership, and the first "stage" of the tool's deployment, brought some of Nvidia's high-powered H100 AI chips to the dying nuclear plant, and with them the compute power needed for generative artificial intelligence.
Running on an internal server without cloud access, Neutron Enterprise's biggest use case, much like so-called AI "search engines," is summarizing a massive trove of millions of regulatory documents that have been fed into it. According to Atomic Canyon CEO and cofounder Trey Lauderdale, this isn't risky — though anyone who has used AI to summarize information knows better, because the tech still often makes factual mistakes.
Speaking to CalMatters, PG&E executive Maureen Zalawick insisted that the AI program will be more of a "copilot" than a "decision-maker," meant to assist flesh-and-blood employees rather than replace them.
"We probably spend about 15,000 hours a year searching through our multiple databases and records and procedures," Zalawick explained. "And that's going to shrink that time way down."
Lauderdale put it in even simpler terms.
"You can put this on the record," he told CalMatters. "The AI guy in nuclear says there is no way in hell I want AI running my nuclear power plant right now."
If that "right now" caveat gives you pause, you're not alone. Given the shifting timelines for the closure of Diablo Canyon in a state that has been painstakingly phasing out its nuclear facilities since the 1970s over concerns about toxic waste — and the fact that Lauderdale claims to be talking to other plants in other states — there's ample cause for concern.
"The idea that you could just use generative AI for one specific kind of task at the nuclear power plant and then call it a day," cautioned Tamara Kneese of the tech watchdog Data & Society, "I don't really trust that it would stop there."
As head of Data & Society's Climate, Technology, and Justice program, Kneese said that while using AI to help sift through tomes of documents is worthwhile, "trusting PG&E to safely use generative AI in a nuclear setting is something that is deserving of more scrutiny." This is the same company whose polluting propensities were exposed by the real-life Erin Brokovich in the 1990s, after all.
California lawmakers, meanwhile, were impressed by the tailored usage Atomic Canyon and PG&E propose for the program — but it remains to be seen whether or not that narrow functionality will remain that way.
