Because how you tune the reactor determines whether you are creating
more plutonium or fissioning it away into other lighter isotopes to the
point where you wind up with low grade uranium, strontium, etc. which is
reprocessed to get the radioactive isotopes for more fissioning, and the
non-reactive isotopes can then be used in industry or disposed of. I
could type up a big paper on it, but you would be better to find
something that is already on the net with regard to the breeder reaction

They have far more greens than we do, but they are educated greens, who
prefer nukes that burn their own waste to smog and adding to the carbon

Read up on it John. I'm actually surprised that you are not aware of

Sure, but you reprocess the waste to extract the remaining radioactive
isotopes for more fissioning, and the non-radioactive isotopes can be
used by industry.

You do if you don't want more waste than you started with. The only
plants we have here in the US for getting rid of our weapons grade
plutonium are, in fact, breeder reactors.

The reprocessing plants are contained and typically automated with
