Crux of The Thing About Thorium: Why The Better Nuclear Fuel May Not Get A Chance by Marin Katusa:

  • Thorium is a better nuclear fuel than uranium, because it’s safer, more abundant, more energy-dense, and produces less radioactive waste.
  • Uranium reactors gained the upper hand because they produce plutonium that can then be used for nuclear bombs, which was desirable during the cold war.
  • Still, “generating the barrage of neutrons needed to kick-start the [thorium] reaction regularly come down to uranium or plutonium, bringing at least part of the problem full circle.”
  • Thorium reactors are planned in India and China, but not in the west. It may be that they are still not economically viable.
