And there is a good solution for storage, but the allies of the fossil fuel industry have combined with the anti nuclear folks to block Yucca mountain from opening. Bury the nuclear waste deep in the earth, because that is where it came from in the first place.
It is very sad for the thousands of people that lost their homes because of radiation around Fukushima. But compare that evacuation to the effects of the earthquake and tsunami itself, which claimed the lives of 15,885 people and injured 6,148 with 2623 people still missing, the response to the radiation leak is just one after effect of the tsunami, but it hasn't caused any deaths.
As for "Such a fire will render the U.S "virtually" uninhabitable.".... a hundred nuclear weapons were detonated on the US mainland as part of above ground nuclear weapons tests. While I think that was incredibly stupid and irresponsible and there have certainly been health effects and increased cancer deaths in the decades afterwards, the radiation leaks at nuclear power plants pale in comparison to the radiation released by those above ground tests and as far as I can tell the US is still inhabitable.
