// the signal · what the data says
AI demand revived nuclear: legacy restarts (Crane/TMI, Palisades) return quickly, while SMRs (Kairos, X-energy, TerraPower, NuScale) promise 2027-2030 first power but remain first-of-a-kind risk. Capacity factor (~92% for nuclear) is the reason AI operators want firm nuclear over intermittent renewables.
