Nuclearn Unleashes Gamma2, The World's Largest AI Model Built for Nuclear

Live Across the U.S., Canada, and U.K., Gamma2's 32-Billion Parameter System Resolves Plant Issues in Hours, Not Years.

PHOENIX, June 18, 2025 /PRNewswire/ -- Nuclearn, the first AI-driven solutions provider for the nuclear industry, today announced that Gamma2—its 32-billion-parameter large language model (LLM) purpose-built for nuclear power—is live and delivering results across the U.S., Canada, and the U.K. In early trials, Gamma2 resolved a two-year auxiliary feedwater pump issue at a major Texas plant in under four hours, synthesized two decades of pump history, and pinpointed the fix before the following shift change. Built by nuclear professionals and trained on more than 4 terabytes of regulatory and operational data from the NRC and IAEA, Gamma2 understands the technical language, acronyms, and licensing context that generic models routinely mishandle.

The mission of Gamma2 is to help utilities reduce O&M costs by 30–50% by automating high-effort tasks, supporting long-term reactor viability, and advancing global decarbonization goals.

"Every dollar we save on operations keeps reactors online and carbon out of the atmosphere," said Jerrold Vincent, Co-Founder and CFO of Nuclearn. "With Gamma2, nuclear finally has an AI brain fluent in its language."

Real-World Impact
Already used in operations across 23 reactors, Gamma2 has cut troubleshooting and document development time by up to 98%. Teams rely on it for FSAR lookups, safety evaluations, root cause analysis, and procedure development, drastically improving operational insight and efficiency.

Unlike general AI, Gamma2 was explicitly built for nuclear environments. It supports secure deployments across 10 CFR 810-compliant, on-premise, air-gapped, or SaaS models. Full audit trails, real-time QA tools, and output traceability come standard.

"Most AI models are like hiring a top grad with no nuclear experience—smart, but not plant-ready," added Vincent. "Gamma2 is different. It's like working with a 30-year nuclear veteran who remembers every regulation, procedure, and lesson learned—instantly."

"This feels like nuclear's iPhone moment," said Phil Zeringue, CRO of Nuclearn. "While others debated what AI could do, we built what it can do for nuclear energy."

Availability
Gamma2 is available now through the Nuclearn platform. Organizations can request a demo at www.nuclearn.ai.
