Project Overview

The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities interactions for the Natrium reactor.  The Natrium designs combines features from the previous GEH PRISM and TerraPower Traveling Wave designs.  The proposed Natrium reactor is a 345 MWe pool type sodium fast reactor using HALEU metal fuel.

For more information, please see the Natrium pre-application documents (NRC Docket 99902087).
