Fast Reactors and Thorium
...physics of reactors is covered in more detail. Thermal reactors benefit from the enhanced chance of nuclear fission when thermal neutrons come close to and interact with a U-235 or Pu-239 nucleus. The slowing of the fast neutrons is not essential, however, for a controllable nuclear reactor, and such thinking lies at the heart of a different class of reactors: the ‘fast...
