Nuclear isn't renewable precisely, but the amount of fuel available is extremely large and not being decreased by any appreciable amount. Waste storage can be handled quite easily by reprocessing fuel, the waste is very small in comparison to other types of energy. There's little to no relationship to arms proliferation, that's only a very specific type of reactor and fuel that's not in general use for nuclear power. And finally there's a lot of water on the planet. Cooling isn't a difficult problem. The bigger problem is that reactor research has essentially been stopped due to nimby problems, so we don't even know how much better we could make nuclear power.
