Carbon-free power for the clean energy transition

The Natrium™ reactor and integrated energy system redefines what nuclear technology can be: emissions-free, competitive and flexible.

The Natrium technology is built for the 21st century grid and is one of the fastest and lowest-cost paths to advanced clean energy that the world needs.

Natrium Reactor

The Natrium Technology

The Natrium technology — a 345-megawatt sodium fast reactor coupled with a molten salt-based integrated energy storage system — provides clean, flexible energy and stability for the grid.


Natrium Project in Wyoming

TerraPower is working to advance a Natrium reactor demonstration project at a retiring coal plant in Kemmerer, Wyoming. The advanced energy demonstration project is intended to validate the design, construction and operational features of the Natrium system. The project will bring a commercial operating, advanced nuclear reactor online that will deliver carbon-free, reliable power to the electric grid and provide good-paying jobs in Wyoming for decades to come.
