The Power Allocation

Why SMRs Won't Save Us Until 2030


Listen Later

Small modular reactors have become the energy solution every AI company wants to talk about. But the timeline reality is stark: the earliest SMR-powered data centers won't come online until late 2027 at the absolute earliest, with more realistic estimates pointing to 2030 or beyond.

Key topics covered:

  • Hyperscaler nuclear deals: Meta/Oklo, Amazon/X-energy, Microsoft/Constellation, Google/Kairos
  • Actual SMR timelines: Oklo Aurora (2028), TerraPower Natrium (2030), Kairos/Google (2030)
  • NuScale's cancelled Utah project and lessons learned
  • First-of-a-kind nuclear: regulatory review, financing, and execution risk
  • The timing mismatch between AI demand growth and SMR availability
  • What fills the gap: natural gas, grid power, and existing nuclear restarts
