the 5th Fact involves what I first worked on back in the 70's...i.e. Advanced Nuclear Reactor designs ("Fast Breeders")...and the ancillary 'ReProcessing', or 'ReCycling' of Used Fuel. Employing a "Closed Cycle" process (already demonstrated...Google "IFR") not only dramatically reduces the amount of radioactive waste products, but also increases the amount of usable fuel by a factor approaching 100X!...not bad.
I'll be happy to go deeper if you'd like.
