TerraPower's reactor design targets AI load spikes

TerraPower’s 345-megawatt Natrium reactor design stores excess heat in a molten-sodium reservoir, letting it generate extra steam during AI compute demand spikes without slowing the reactor itself, aiming to beat the 92.5% average capacity factor of US nuclear plants. Meta agreed in January to buy eight Natrium plants; the first is under construction in Wyoming, with a second data-center project expected to break ground in 2027.
