I'm still not opposed to nuclear power, even after the flustered cluck that went down with Fukushima Dai-ichi. That being said, I caught this interview with physicist Michio Kaku, and the professor plainly states that we came real close to losing all of Northern Japan as a habitable area; and would have done if TEPCO had not been forced to pump seawater into the reactors. All jokes about Tohoku aside, that's just gobsmackingly nuts.
100% meltdown and clowns at TEPCO were apparently more concerned with their investment than the Japanese people. Good to know.
