If the world attempted to convert its energy use from oil to nuclear power, to replace this oil we would need to build over 10,000 new nuke plants. These plants would then completely deplete the Earths reserves of uranium in about 25 years.

However: a new type of reactor utilizing thorium shows promise- these reactors will never suffer a dangerous meltdown, and their radioactive waste byproducts would only be hazardous for a few hundred years, instead of thousands of years as for uranium. We might even be on the threshold of devising a way to 'eat' radioactive waste with electro-chemical processes.
