Worse than meltdown
Recent reports confirming that Reactors 1, 2, and 3 of the Fukushima Daiichi nuclear facility completely melted just hours after the devastating earthquake and tsunami hit the area on March 11 (http://www.naturalnews.com/032537_F...) have been trumped by even worse news that those same reactors have all likely "melted through," a situation that according to Japan's Daily Yomiuri DY is "the worst possibility in a nuclear accident."
And senior political official Ichiro Ozawa suggested in an interview with The Wall Street Journal (WSJ) that the Fukushima situation could make the entire country of Japan "unlivable."
An explanation follows and it describes the difference between a "meltdown" and "melt-through":
A nuclear core meltdown involves nuclear fuel exceeding its melting point to the point where it damages the core, leaks out, and threatens to potentially release high levels of radiation into the environment. However, a nuclear melt-through is an even worse scenario, as nuclear fuel literally melts through the bottom of damaged reactor pressure vessels into out containment vessels -- and possibly even melts through those outer vessels directly into ground, air, and water.
The report suggesting that melt-throughs have already occurred, which is set to be submitted to the International Atomic Energy Agency (IAEA), is the "first official recognition" of this dire situation, according to DY.
It also confirms early suspicions that such a scenario had been underway all along, as later reports confirmed that the epic disaster at the reactors had produced holes in come of the plant's core containment vessels, and that radioactive water, and possibly even fuel, were leaking into the lower vessels.
In an interview conducted prior to the release of the new report, Ichiro Ozawa told the WSJ that areas around Fukushima were already becoming completely "uninhabitable." He also suggested that as it currently stands, much of the rest of the country, including Tokyo, could suffer the same fate if nothing is done to properly and effectively contain the situation.
It is hard to know what to add to this article. This situation will continue to evolve.
As a reminder of what can happen, it may be worth a look back at Chernobyl:
