Japan Nuclear Crisis-JAIF data shows situation melting down.

The reports from JAIF concern me most when you look at the details.
They show that Unit's #5 and 6 are of such concern that they punched a hole in the roof of one or both to help evacuate hydrogen build up. Hydrogen buildup implies that a chemical reaction has been occurring between the casing and water for some time due to overheating. It appears to me that they are well on their way to causing explosions similar to what we have seen in other units with associated radiation increase and meltdown of pond contents. JAIF has indicated some resumption of electricity and pumping at 5 and 6, but no report of any success in lowering the pond temperature. #5 and #6 might be melting now, or will be as situation escalates.
Unit #4 is receiving no attention. High radioactivity, a largely intact roof, and damage to the pool structures seem to have precluded any sensible response at #4. #4 continues to melt.
Unit #3 has had a little water sprayed on it with unknown effect. At last known report, days ago #3 had failed containment and partial meltdown. Spraying water might help slow the melting of the pond, but not be able to penetrate to cool core at all.
The data shows core exposure at #1, 2, and 3 but water and pressure levels remaining fairly steady. This makes no sense. If the cores were half exposed days ago, how is it that the water level is remaining steady? There are no reports of any ability to supply water to the cores of 1, 2, or 3. Units 1, 2, and 3 are melting.

It is my belief that the situation continues to spiral completely out of control. To varying degrees, all six units are, or are in danger of, melting down. Radiation release will continue to rise steadily. There is no effective response to the situation.
