  Also some one on this site? asked me where i got my info about uranium, i said 60 years [ I was wrong it is 16 years, fossil fuelled power stations are out carbon trading is a lie every atom of carbon released into the atmosphere can stay there for up to 100 years] this is from a professor of nuclear physics
   
  Martin,

This is not an easy question to answer, and some parts of the answer are quite contentious. At present usage rates the high grade ore bodies currently being mined would last around 80 years. If nuclear power went from providing 16% of the world's electricity to 80%, then this reduces to 16 years. This suggests that, if lower grade ores are not effectively available,  nuclear electricity has a limited future. It would also imply that expanding nuclear power is counter-productive in terms of combating greenhouse gas emissions. 

The availability of the lower grade ores is the contentious point, where availability means,  does it take more energy to extract uranium from an ore body than we can deliver to users from its use in electricity production? Those who believe that it is effective in this sense (for example, the International Atomic Energy Agency) say at current usage levels there is enough uranium to last 270 years, or 54 years at the 80% of electricity level. Once this is exhausted some believe we can extract uranium from seawater, and if this turns out to be true, then there is enough to last thousands of years, as most of the worlds uranium is dissolved in seawater in the oceans.

    Dear Martin,
  Â 
  Thank you for your enquiry to CSIRO regarding Uranium.
  Â 
  Regrettably we are unable to answer this query as it is not a specific area of CSIRO research.
