A recent article in Wired discussed a “new”ish method of nuclear power utilizing thorium instead of uranium.  It appears to be cheaper, safer, more efficient, takes up less space and goes forever.  So why can’t we get more buy in?  Nuke is nuke I suppose.  Lets forget the cap-n-trade crap or quit burning bundles of carbon to get to Copenhagen and develop this stuff! That’s my “global warming” answer.  Now only if the government will back off to allow it and hopefully some archaic nuclear utilities will explore it too.  One of the big proponents, Kirk Sorensen, runs a blog called “Energy from Thorium“.  Check it out, the first “open source project” for nuclear power.  The article is excellent and interesting. Check out this comparison sheet from the article of three possible reactors:

  • Uranium-Fueled Light-Water Reactor
  • Fuel Uranium fuel rods
  • Fuel input per gigawatt output 250 tons raw uranium
  • Annual fuel cost for 1-GW reactor $50-60 million
  • Coolant Water
  • Proliferation potential Medium
  • Footprint 200,000-300,000 square feet, surrounded by a low-density population zone
  • Seed-and-Blanket Reactor
  • Fuel Thorium oxide and uranium oxide rods
  • Fuel input per gigawatt output 4.6 tons raw thorium, 177 tons raw uranium
  • Annual fuel cost for 1-GW reactor $50-60 million
  • Coolant Water
  • Proliferation potential None
  • Footprint 200,000-300,000 square feet, surrounded by a low-density population zone
  • Liquid Fluoride Thorium Reactor
  • Fuel Thorium and uranium fluoride solution
  • Fuel input per gigawatt output 1 ton raw thorium
  • Annual fuel cost for 1-GW reactor $10,000 (estimated)
  • Coolant Self-regulating
  • Proliferation potential None
  • Footprint 2,000-3,000 square feet, with no need for a buffer zone
  • Well, I’m sold (at least enough to want to explore it further!)
