Quote from Pekelo:
So uranium ore suddenly started to replenish itself??
Your argument (beside being offtopic in a peak oil thread) is based on better waste product usage and doesn't address my point of uranium ores being a limited resource...
Any resource is finite. You have to crunch the numbers if you want to find out how likely it is that it will be exhausted. With Gen IV nuclear there is no chance of exhausting uranium for hundreds of years and probably a lot more. And the significance is not limited to "burning" waste. Natural mined uranium is just as good.
Known world recoverable uranium reserves: 5,469,000 tonnes
Required uranium for Gen IV 1GWe power plant for one year: 1 tonne
Current world generation capacity ~ 4000 GWe
Back of envelope calculation: 1,367 years at current production levels. If push comes to shove uranium can be recovered from sea water.
If you don't like the uranium-plutonium fuel cycle, then how about the thorium-uranium cycle. There is several times as much readily recoverable thorium as uranium in the world. The Indians are pursuing this because of their lack of uranium.
There will be peak oil (and coal) sooner or later, discussion of energy futures is highly relevant.
