Assuming there won't be any disasters worse than what has already occurred.
Presumably any new nuclear capacity would use safer designs, but still, the tail end single event worst case scenario is a lot scarier.
(Before you say Fukushima, remember the carnage and death was caused by an insanely catastrophic tsunami. Despite massive incompetence and disastrous consequences, it has resulted in a grand total of 1 death so far, with perhaps a few dozen over the lifetime of all people in the area. Not nothing, but it shows just how safe this stuff is when you extricate paranoia from the equation.)

Choice quotes:
"Short answer not much would happen. There just is not enough of them and even in the worst case breakdown they don't release that much radiation."
"Even if every single reactor in the US 'failed' today, I doubt there would be significant radiation leakage ... without a 40 foot tsunami, I think this is more like Three Mile Island."
"The problem is that there is a great deal of exaggeration in the public's idea of radiation - the "Omigawd, it's radioactive! We're all gonna DIE!" effect."
