Fukushima will belittle Chernobyl. The Japanese Government has had a nuclear disaster at level 7 go for almost a week but it will not accept it. The disaster is going the opposite way as Chernobyl, which exploded and stopped the reaction. Fukushima, the reactions are getting worst. I suspect that three nuclear batteries are in the merger and we’ll probably get some of it.
If the 3 reactor is in the merger, concrete under contention seems lava. But Fukushima is not far away from the water table. When this molten mass of independent nuclear material gets economically to the water table it will not cool just below. Not a nuclear explosion will explode, but it will quite probably involve other reactors and ease fuel rods. Concrete pouring in a critical reactor has no sense will explode and be launched simply a more radioactive particulate matter. Daily news – concrete will melt and the problem will get worse.
Chernobyl a critical reactor exploded and stopped the reaction was different. Fukushima, the reactor cores are still melting. The only way to stop that is to detonate a fission device of 10 kiloton within each container and hope of containment of the reactor to vaporize the hearts. That’s probably a bad solution. A nuclear fusion is a reaction independent economically. Nothing can stop it except for the arrest of the reaction. And that would require a nuclear weapon. In fact, one in each bowl of containment would require stop simply what now is lighting. But it will be dirty. Fukushima was waiting to happen because of the placement of the emergency generators. If they did not all failing immediately flooded by a tsunami, Fukushima would have not happened as it did though it had still been a nuclear disaster.
