Also, uranium is not the only nuclear fuel source! Another possibility is Thorium fuel, which produces less waste, is far more common than uranium, gives more energy per kg, and is far more easily controlled. Nations such as China (I think) have been investing in this kind of technology.

Edit: However, thorium reactions are not self-sustainable on their own and need a "helper," such as uranium or plutonium. This isn't entirely a bad thing, though, as if you take away the helper material, the reaction should die on its own.

The 'produces less waste' part is a breeder or molten salt reactor advantage, not a thorium advantage. It works just as well on the uranium fuel cycle.

The advantage of thorium fuel cycle in particular, for the moment is that there are already mined stockpiles of thorium in certain countries (like India) with nothing to do with them. But other than that, both fuels are abundant enough. The disadvantage is that the thorium fuel cycle inherently requires a breeding step, which means there's a higher bar for entry. You need to work with and reprocess irradiated fuel, which is a bit more difficult and only done in a few countries. Or you need a more complicated design (MSR) which is also only done in a few countries. That's part of why they're only starting to seriously consider it now instead of earlier.
