Nuclear would become much more practical, safe, and cost-effective, and it could last hundreds of years longer if we could perfect breeder reactors. These reprocess the waste into more fuel for further nuclear reactions, so they dramatically reduce the waste that needs to be stored and also stretch the limited supply of uranium much farther. In addition, they can allow the use of thorium, which is more abundant than uranium.
It is true that nuclear is subsidized by the public, but as energy costs rise all around, it becomes more cost-effective, especially as newer approaches are perfected as noted above. France successfully generates more than half of its electricity from nuclear, so it is clearly feasible.
