In hindsight Fukushima should not have been operating in a tsunami zone, and in foresight no nuclear power should operate in earthquake zones or next to volcanoes or in general in any place prone to high-energy natural disasters. The problem with high-energy natural disasters is that you generally don't get a nice upper bound on the energy, rather you get an exponential falloff in probability of a disaster happening of higher and higher energies. So it's basically impossible to guarantee that the plant will survive, you can only make probabilistic arguments. That isn't good enough.
