You can use Uranium to make Plutonium. In fact a fast breeder makes more
fuel than it uses..

I don't think that is so.
The works I consulted suggest that the addition of plutonium to uranium
in MOX plants reduces uranium needs by about 30%.
Against this, extraction of plutonium multiplies high-level waste
about 17 times.
For this reason, the technique is not considered economic at present.

Fast breeders are used principally for weapon production.
