The fuel is neither limitless nor does it regenerate itself (unless you use a Breader, like at Dounreay in Scotland, but that's closing/closed now)

There is a limited amount of fissile uranium, the currently used core material. However there are thorium reactors on the drawing boards. If the work, they will add 250 times the current estimated nuclear energy source. Breeder reactors create more material than they use. I don't really understand how.

takes a minimum 2~3 to produce one nuke warhead I believe the energy is the same its not that's it not renewable its a long process... I like nuke but I know a better boooooom

toxic waste takes 10k years to stop being radio active. The byproduct of nuclear power

The earth only has a certain amount, and it is dangerous to recreate. Now if we were able to mine from stars and other celestial things, then that's a whole other story in itself I imagine.
