Who needs Three Mile Island or Chernobyl when you can have dozens, if not hundreds of mini meltdowns in your very own neighborhood? That may be a nightmare scenario which has little basis in fact, but that’s the stigma that Toshiba will have to combat if it wants to see its 200 kilowatt micro nuclear reactor take off. The mini reactor measures 20 feet by 6 feet and is designed to be “fail-safe, totally automatic and will not overheat.” The reactor will have an energy production half life of 20 years and has the promise to make cheap electricity for around a nickel per kilowatt hour.”
