The Japanese government and Tepco claim that the nuclear reactors are "stable" and that radiation releases have subsided to low levels.
But world renowned physicist Michio Kaku - who studied under atom bomb developer Edward Teller - told Democracy Now today:
Tokyo Electric has been in denial, trying to downplay the full impact of this nuclear accident. However, there’s a formula, a mathematical formula, by which you can determine what level this accident is. This accident has already released something on the order of 50,000 trillion becquerels of radiation. You do the math. That puts it right smack in the middle of a level 7 nuclear accident. Still, less than Chernobyl. However, radiation is continuing to leak out of the reactors. The situation is not stable at all. So, you’re looking at basically a ticking time bomb. It appears stable, but the slightest disturbance—a secondary earthquake, a pipe break, evacuation of the crew at Fukushima—could set off a full-scale meltdown at three nuclear power stations, far beyond what we saw at Chernobyl.
When the utility says that things are stable, it’s only stable in the sense that you’re dangling from a cliff hanging by your fingernails. And as the time goes by, each fingernail starts to crack. That’s the situation now.
TEPCO is like the little Dutch boy. All of a sudden we have cracks in the dike. You put a finger here, you put a finger there. And all of a sudden, new leaks start to occur, and they’re overwhelmed.
I suggest that they be removed from leadership entirely and be put as consultants. An international team of top physicists and engineers should take over
