You’re obviously not willing to change your mind, so this will be my last response. Googling “breeder reactor” will show you plenty of peer reviewed papers and findings from past experimental reactors that can answer your questions.

Apart from that, the point of the technology is obviously not to replace renewables, it’s to

1. Phase out coal and oil as fast as possible.
2. Get rid of the nuclear waste we already accumulated (by turning it into energy).

Especially point 2, you are obviously and rightfully worried about nuclear waste - breeder reactors are the solution, the only one we currently know of. What else do you suggest we should do with that waste? Store it for millennia?

Last you checked? When was that?
