Nuclear Is Back — And It's Smaller
After decades of stagnation, nuclear energy is experiencing a genuine renaissance in 2026. The catalyst isn't environmentalism — it's AI data centers. The explosion in AI compute demand requires massive amounts of reliable, carbon-free baseload power. Solar and wind can't deliver 24/7. Nuclear can. And the new generation of Small Modular Reactors (SMRs) solves the cost and safety problems that killed traditional nuclear.
What Are Small Modular Reactors?
Size: SMRs generate 50-300 megawatts, compared to 1,000+ MW for traditional reactors. Small enough to fit on a few acres. Cost: Factory-built modules shipped to site, reducing construction costs by 40-60%. Traditional reactors cost $10-15 billion and take 10-15 years. SMRs target $2-4 billion and 3-5 years. Safety: Passive cooling systems that shut down automatically without human intervention. Physically impossible to melt down in most designs.
Who's Leading the Race
NuScale Power (SMR): The first SMR to receive NRC design certification. 77 MW modules, targeting first commercial deployment by 2029. Stock has been volatile but the technology is real.
Oklo (OKLO): Sam Altman-backed microreactor company. 15 MW fast reactor design using recycled nuclear fuel. The AI-nuclear connection is literal — OpenAI's chairman is funding it.
TerraPower: Bill Gates' nuclear venture. Natrium reactor design using molten salt energy storage. First plant under construction in Kemmerer, Wyoming.
X-energy: High-temperature gas reactor with pebble bed design. Partnered with Dow Chemical to power industrial facilities. Received $1.2B in DOE funding.
Rolls-Royce SMR: UK-based, targeting 470 MW modular reactors for the British grid. Government backing of $700M+.
The AI Connection
Microsoft signed a deal to restart Three Mile Island to power its AI data centers. Amazon invested $500M in X-energy. Google signed a nuclear PPA with Kairos Power. The pattern is clear: Big Tech needs nuclear for AI. AI training runs consume 10-100 MW of continuous power. SMRs are purpose-built for this use case.

Investment Thesis
The nuclear energy ETF (NLR) is up 45% over the past year. Individual plays: Cameco (CCJ) for uranium supply, Constellation Energy (CEG) for existing nuclear fleet, NuScale (SMR) and Oklo (OKLO) for SMR pure plays. Uranium prices have tripled since 2020 to $95/lb. The supply-demand imbalance is structural — it takes 10-15 years to bring new uranium mines online. This is a decade-long trend, not a trade.
