Bill Gates' Terrapower: A Window Into the Nuclear Future

TerraPower—with the backing of Bill Gates—has a radical vision for the reactors of tomorrow

• Thanks to his role funding and guiding a start-up called TerraPower LLC, where he serves as chairman, Mr. Gates has become a player in a field of inventors whose goal is to make nuclear reactors smaller, cheaper and safer than today's nuclear energy sources 
• "A cheaper reactor design that can burn waste and doesn't run into fuel limitations would be a big thing," Mr. Gates says
• The type of reactor TerraPower is working on, ... could reduce the need for enrichment and reprocessing of uranium. 
• It's a slow, controlled reaction that could continue over many years without need of human intervention.
