And regarding an earlier post, the reason why those scientists resigned 35 years ago was because they believed that these specific kind of reactors should not be built, if there was trouble and there was a loss of power, those reactors won't be able to cool down sufficiently and that is exactly what's happening now. They were so upset about it that they left their job and walked out of the company. It doesn't matter that they retrofitted the reactors to strengthen the containment, the main problem still exists. It's like designing a car and you find out that it has a braking problem and instead of redesigning it, you just put some extra airbags in there.
