> Breeder reactors of any kind are a proliferation risk. We also don't need them. Thorium fueled reactors are a better choice, both for the availability of fuel and the lowered risk. The Thorium fuel cycle is, by definition, a breeding fuel cycle because Th doesn't naturally contain any fissile isotopes. U-233, which is the fissile isotope that is the actual fuel in the Th cycle, is perfectly fine as a bomb material, so you have similar proliferation worries as with a U-Pu fuel cycle.
