Doesn't matter how much you prepare if it is really bad. All of the nuclear plants world wide that will not be monitored because the people taking care of them will be taking care of their families. Point being, we have FUKU times 2 to 3 hundred. This world would not be livable within months. The big wigs have created a time bomb in all of the plants. They would have to stay underground the rest of their lives. Who knows maybe they have planed that. Good luck all.
