What about uranium depletion? Never mind how safe we can make it, or how cost-effective... neither of these things matter if we run out, and I can't find a definite, comprehensive study on how long it could last. Projections range from a decade to seven decades using current technology, or longer than the life of the sun using breeder reactors and seawater-uranium extraction technology. Considering it is essentially nonrenewable (breeder reactors don't create new uranium, per se, just extend the lifespan of the stuff we've got) this is an important question to ask. Does anyone know of a good, comprehensive study on this? My google-fu is weak on this topic. http://en.wikipedia.org/wiki/Uranium_depletion#Pessimistic_uranium_depletion_outlook http://en.wikipedia.org/wiki/Uranium_depletion#Pessimistic_u...
