Re: Global warming (was:Chernobyl " population will continue to slidetoward extinction ")
Jaro, Ted & Radsafers,
Sorry, Jaro, I only joined after the 'hijack'! Ted, I checked the million
tonnes natural U3O8, and with typical PWR burnup the yield would only be
about 0.5Q (thermal). Breeders can change this picture dramatically;
another reason why 'spent ' fuel is a valuable resource which should not be
disposed of irretrievably.

Please respond to Ted
de Castro
Thanks for some real numbers HOWEVER I am a bit skeptical of the last
one! ALL generated power that does not go into making a chemical bond
(that is not later undone) or assists in a phase change that is stable
at ambient - eventually ends up as waste heat! And with 1 kiloton =
4.18 E12 a "Q" is about 1/2 kilo-megaton - and I would think THAT much U
would be good for a whole lot more than that!
Just a feeling.
