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.



Any idiot can face a crisis - it's day to day living that wears you out.
