When the Fukushima Meltdown Hits Groundwater | Hawai`i News Daily

Fukushima is going to dwarf Chenobyl. The Japanese government has had a level 7 nuclear disaster going for almost a week but won't admit it.

The disaster is occurring the opposite way than Chernobyl, which exploded and stopped the reaction. At Fukushima, the reactions are getting worse. I suspect three nuclear piles are in meltdown and we will probably get some of it.

If reactor 3 is in meltdown,  the concrete under the containment looks like lava. But Fukushima is not far off the water table. When that molten mass of self-sustaining nuclear material gets to the water table it won't simply cool down. It will explode - not a nuclear explosion, but probably enough to involve the rest of the reactors and fuel rods at the facility.

Pouring concrete on a critical reactor makes no sense - it will simply explode and release more radioactive particulate matter. The concrete will melt and the problem will get worse. Chernobyl was different - a critical reactor exploded and stopped the reaction. At Fukushima, the reactor cores are still melting down. The ONLY way to stop that is to detonate a ~10 kiloton fission device inside each reactor containment vessel and hope to vaporize the cores. That's probably a bad solution.

Environmental activist group Greenpeace said it had confirmed radiation levels of up to 10 microsieverts per hour in Iitate village, 40 kilometres northwest of the plant, and urged the government to evacuate the area. "It is clearly not safe for people to remain in Iitate, especially children and pregnant women, when it could mean receiving the maximum allowed annual dose of radiation in only a few days," said its radiation safety expert Jan van de Putte. "The authorities must stop choosing politics over science and determine evacuation zones around the Fukushima nuclear plant that reflect the radiation levels being found in the environment."
