Who makes SMRs for AI data centers
Small modular reactors and other advanced reactor designs, plus the components, fuel, and enrichment supply chain that would build and run them.
This category spans developers racing to commercialize small modular and advanced reactor designs, the specialist manufacturers who would supply reactor-grade components, and the fuel and enrichment chain (including uranium mining) that feeds any reactor, new or existing. None of these designs have been built and licensed at commercial scale for a data center yet, which separates this category from the existing-fleet PPAs in Layer 8.04 — this is a bet on future supply rather than a claim on current output. The output of an SMR would ultimately connect through the same transmission and interconnection equipment described in Layer 8.09. AI demand has been the single biggest driver of new capital and offtake commitments into SMR developers, but licensing, first-of-a-kind construction risk, and fuel supply (particularly HALEU enrichment capacity) remain unresolved for nearly every design in this category. An investor should weigh developer timelines against enrichment capacity, since a shortage of enriched fuel could bind even a successfully licensed reactor design.
AI delta: AI operators have become the largest source of offtake commitments and equity capital for SMR and advanced reactor developers, betting on future firm carbon-free supply years ahead of any commercial operation.
