>Uranium running out

Not a problem, once the nuclear can of worms has been opened.  As long
as the technological level of the civilization stays high enough to run
a reprocessing plant, there's no limit on growth of fissionables.   See
also "Fermi Paradox" ....

The Japanese government says its stockpile of plutonium had grown to
43.1 tons as of the end of 2004, up 2.4 tons from 2003. ... The
increase reflected suspension of a project to burn plutonium at
conventional nuclear power plants .... Japan also has unreprocessed,
spent nuclear fuel believed to contain more than 110 tons of plutonium.
...Of the 43.1 tons of plutonium, 29.3 tons are believed to be
fissionable.    www.physorg.com/news6316.html
