What is "terrapower"

TerraPower is a nuclear reactor design company headquartered in Bellevue, Washington, in the United States. TerraPower is a class of nuclear fast reactors called the traveling wave reactor (TWR). TerraPower is partly funded by Los Alamos National Laboratory. Unlike standard light water reactors such as PWRs or BWRs that operate by using enriched uranium as fuel, TWR uses depleted uranium instead, with an estimated operation period from 40 to 60 years. The byproduct of the Uranium-235 fission can be re-used for other TWR reactors.
