TerraPower’s nuclear reactor offers a strategic edge for AI data center deals

TerraPower’s Natrium reactor design can deliver a steady 345 MW of baseload power, then ramp up to 500 MW for more than five hours when demand spikes. The trick is an integrated molten salt energy storage system that effectively acts as a thermal battery, absorbing excess heat during low-demand periods and releasing it when the grid, or an AI training cluster, needs the extra juice. The Meta deal and what it signals In January 2026, Meta signed an agreement with TerraPower for up to eight Natrium units. The projected baseload capacity across those units sits at roughly 2.8 GW, with storage capabilities pushing the effective output to approximately 4 GW. Meta’s broader nuclear initiative reportedly targets up to 6.6 GW across several projects, all aimed at feeding the computational demands of its AI infrastructure. The TerraPower deal, with units projected for delivery by 2032, represents the kind of multi-year energy commitment that hyperscalers are increasingly willing to make.
