A design for a Thorium nuclear reactor addresses one of the biggest fears associated with nuclear power – meltdown. A fission reaction can be maintained by firing a proton beam (similar to that generated by the Large Hadron Collider at CERN) in a straight line aimed at Thorium fuel (which is both more abundant and generates less nuclear waste than Uranium). The reaction can be turned off by switching off the beam. No Fukushima style meltdown if the power fails.
Sounds like a winner to me. Construction starts in 2015, should be operational by 2023. Can’t wait. Let’s hope it lives up to expectations.
