Bill Gates goes nuclear in Idaho

Bill Gates, along with the staff of nuclear startup TerraPower, visited the U.S. government-owned Idaho National Labs this week to check out the facilities in advance of reactor design work that TerraPower plans to do at the facility. Gates is chairman of, and investor, in TerraPower, which has been developing a traveling wave nuclear reactor that can run on waste uranium, and can make and consume its own fuel — theoretically it doesn’t need to be refueled for hundreds of years.
