1. if a real effort is put in, 10 years or so 2. Solved problem. Spent fuel is not really an issue, we have solutions and areas to put it in both Europe and the USA. Only green Luddites hold it back. Storage really does not take up a lot of space. 3. Next to none if the right type of fuel stock and reactor is chosen. Obviously security comes in, but that is also a solved issue 4. Lots of modern designs literally cannot go critical, I suggest we use those, instead of old designs just because they're "a known known". 5. don't build reactors that can go critical near known tsunami shorlines. 6. At worst we'll surely have fusion by the end of the century and can then retire the nuclear plants. Solar and wind without a 100x improvement in battery storage tech do not make sense right now as the sole producer of energy like a lot of unrealistic "environmental" groups claim.
