having read the Peak Oil thread, and the various responses saying we
should build nuclear power stations, it reminded me of an article I read
a while ago about Peak Uranium. Have we maybe missed that boat already ?

http://en.wikipedia.org/wiki/Peak_uranium


In that same wikipedia article, under the heading "Optimistic
predictions for peak uranium", is the statement:

"A nuclear engineer writing for American Energy Independence in 2004
believes that there is a several hundred years' supply of recoverable
uranium even for standard reactors. For breeder reactors, 'it is
essentially infinite'".

i.e. until the sun burns out in 4.5 billion years.

Maybe the answer lies halfway between the two estimates?

David Mackay reckoned 750 years.

wood lasted about 10,000 years, coal about 200, oil about 100, in this
country.
