I live in Minnesota and we do have nuclear plants in the area. The worst natural disasters we suffer in the Midwest are tornadoes, snow and the occasional river flooding. There aren't massive earthquakes, tsunamis, hurricanes, volcanoes, or mudslides. Japan has far few options for where they locate plants, the US isn't nearly as limited. It would seem reasonable that we could make some intelligent decisions on location with a good design. I really don't see the problem for nuclear plants in the US.
Sure some of our nuclear plants are aging, but there is no excuse (aside from $$$) for why we don't update them with new/safer tech.
