A Nuclear Innovation Company

Best-in-class talent demonstrating clean energy solutions


With the growing demand for electricity, TerraPower entered the nuclear energy arena because its founders saw clean energy as the pathway to lift billions out of poverty. The company has since expanded that vision to include the advancement of nuclear science in medical isotopes, offering potentially lifesaving treatment for cancer.

TerraPower is on a mission to tackle some of the most pressing challenges facing mankind with safe, affordable and sustainable technologies. We are ready to build the clean energy of tomorrow – today.
