Just this week, TEPCO released a report http://www.tepco.co.jp/nu/fukushima-...11130_09-j.pdf on this China Syndrome event. The containment vessels are being systematically eaten by a molten mass of core materials. They are chemically reacting with cement which is not rock but rather, is a water-permeable material that reacts to heat .
The molten core of several Fukushima Daiichi reactors is sinking through the Earth’s crust and appears to be in early stages of a “China Syndrome”. If fuel reaches an underground water vein, it will cause contamination of underground water, soil contamination and sea contamination. Moreover, if the underground water vein keeps being heated for long time, a massive hydrovolcanic explosion will be caused.
