AI’s Nuclear Wall: The Power Crisis

By C. Rich

“Project Prometheus” is a well-funded artificial intelligence (AI) startup founded in late 2025 by Jeff Bezos and Vik Bajaj, aiming to advance AI in engineering, manufacturing, and physical-world applications. It is not a single chatbot but a company focused on agentic AI for sectors like aerospace and automotive.

In early 2026, Meta finalized its largest energy play to date, securing 6.6 gigawatts of nuclear power, roughly the capacity of six full-scale reactors, to fuel its new “Prometheus” supercluster in Ohio. This is significant because, unlike Microsoft’s single-plant deal with Three Mile Island, Meta is diversifying across three different providers: Vistra, TerraPower, and Oklo. By spreading its bets, Meta is attempting to insulate itself from the regulatory delays currently plaguing the Three Mile Island restart.

While the funding is present, a new and alarming “infrastructure wall” has emerged this month. Current reports indicate that nearly half of the planned AI data centers scheduled for 2026 are facing delays or cancellations. The bottleneck is no longer just the reactors themselves, but a critical shortage of secondary electrical components, specifically high-capacity transformers and switchgear. Lead times for these components have stretched from two years to five years, forcing tech giants into desperate measures. We are now seeing “cannibalization” of the energy sector, where companies like Crusoe are buying up and refurbishing old transformers from defunct 20th-century coal plants just to keep their AI projects on schedule.

The most tangible progress on the technical front occurred on March 4, 2026, when the U.S. Nuclear Regulatory Commission approved the construction permit for TerraPower’s Natrium reactor in Wyoming. This is the first “next-gen” reactor to be approved in the U.S. in over 40 years. Its importance cannot be overstated: it uses liquid sodium rather than water for cooling, making it far safer and more efficient for the constant, high-heat loads generated by AI training. The tone from Washington has also shifted. President Trump recently emphasized that the “AI Energy Race” is now a matter of national security, framing the competition as a binary struggle between the U.S. and China for nuclear supremacy. This has led to the “Permit-to-Power” initiative, designed to bypass local environmental hurdles that have traditionally stalled nuclear projects for decades.
