Fission at scale is science fiction. There are no closed loop fuel cycles and 6TWe of PWR reactors would exhaust world reserves un under 5 years. Reprocessing all of the waste adds maybe a year, and enriching the tailings adds maybe another year. Sea mining and breeders are significantly less real than 46% efficient solar or 1200Wh/kg AlS batteries.
