Working breeder programs are a myth and condescendingly telling me to watch a video taking a narrow myopic view of things I already know (which ignores all the important points) isn't helping your point.

Show me where I can find documentation of a reactor running on U238 or Th which actually worked for a complete fuel cycle and wasn't just the same breeding ratio as a U235 but with extra steps.

You've also not addressed the hard bit either, which happens outside the reactor.

Also nobody banned breeders, breeder programs are still eating huge amounts of public money and failing to do anything useful in india and china to this day. Superphenix and Monju also weren't banned in the 70s. Nor were the BN reactors.

The only reason they exist is for plausible deniability on filthy loss-making Pu separation equipment for weapons, and for people like you to palter with.
