As hyperscale AI data centers demand unprecedented electrical capacity, nuclear innovation firm TerraPower has unveiled a specialized deployment blueprint for its Natrium fast reactor system. Designed to deliver 345 MW of constant baseline clean power, the system features an integrated molten-salt thermal storage facility capable of boosting output to 500 MW during peak computational workloads.
The Natrium architecture utilizes liquid sodium as a coolant rather than high-pressure water, operating at near-atmospheric pressures and significantly reducing structural risk. The integrated energy storage system allows datacenters to balance intermittent renewable power on local grids while keeping GPU clusters running at 100% capacity.
