This Startup Just Raised $10 Million to Help Nuclear Power Plants Level Up Their Tech

A startup that leverages AI to streamline nuclear reactor operations just got a major cash infusion.

Phoenix, Arizona-based Nuclearn announced a $10.5 million series A round of funding, bringing the startup’s total capital raised to date to about $13 million. The round was led by Blue Bear Capital with participation from SJF Ventures and existing investors AZ-VC and Nucleation Capital.

Nuclearn plans to use the funding to grow into markets beyond the U.S. and Canada, as well as to expand its engineering team, invest in hardware, and grow the tech capabilities of its platform.

Nuclearn builds an AI platform specifically for nuclear plants. The AI is meant to cut down on the complexity involved with running a plant to free up worker time for other tasks. The company reports that its solutions can reduce time spent on various regulatory tasks down from 400 hours to just one day, delivering an estimated 50 to 90 percent reduction depending on the task. “We’re able to draft complex documents, do nuclear-specific research—really help engineers and nuclear professionals accelerate documentation requirements for regulatory, for engineering work,” CEO and co-founder Brad Fox says.

Nuclear plants are notoriously complex to build and operate—and for good reason. Although it is incredibly rare for them to malfunction, when they do the results can be catastrophic. This has led to a meticulous culture of safety in the nuclear industry, which also means a lot of specialized paperwork, documentation, and record-keeping. Nuclearn believes AI can help to streamline some of these processes.

“I would hope to turn every knowledge worker into a reviewer,” Fox says. “We want to rapidly accelerate those peoples’ workflows such that they’re using their skills and their talent, their mindshare to produce novel new documents and new things.”

And given that the International Atomic Energy Agency forecasts that global nuclear capacity could double or even triple by 2050, utilities are more concerned about finding adequate talent than replacing, through automation, the skilled workers they currently employ, Nuclearn co-founder and CFO Jerrold Vincent said during a separate conversation in March.

Workers can interact with Nuclearn’s AI in different ways. Fox explains that Nuclearn offers a suite of products that automate background processes based on client-specific data, as well as a generative AI chatbot called AtomAssist. It helps employees parse through institutional knowledge, draft text, and track changes to ease the creation and validation of technical documents. As far as time savings per product, Nuclearn reports that its Corrective Action Program AI can save up to 70 percent of time spent screening for issues, which translates to about 4,000 hours of a team’s time saved per reactor, per year.

If all this sounds farfetched, it’s not: Nuclearn’s AI platform is already operational in more than 60 of the roughly 113 reactors in the U.S. and Canada. The company hopes to grow its market share in North America, and expand to Europe and the Middle East. Founded in 2021, the company has begun generating revenue and brought in about $2 million in 2024.
