I have faith in the Japanese. They can overcome this.

not just an explosion; it was large. it's hard to believe but it looks like the tower is toast.
The earthquake may now be the lesser of the whole thing. There are 6 operating power plants there. This couold render all of them history. And in the worst case more might melt down. In addition 2 other plants were close to complete.
The costs here are incalculable. It could be a cataclysm.

It can meltdown. TMI Unit 2 did. When the cooling is lost the fuel overheats, the fuel rods melt = meltdown. The heat continues to buildup and fuel melts through vessel and then from there who knows.

What actually exploded?

While I'd like to believe that, and I pray for those people, do you really believe the Japanese gov't is telling the truth?
The outcome of this is not pretty. I'm sure most of us has seen the pics of the Russian plant. The whole area remains uninhabitable today.

Hydrogen explosion.......the video does show some serious force.

Right now, the Gov't and the electric company is the last I would belive to tell the truth.
And they were very proud of the fact that their reactors were "quake" proof with automatic fail-safe mechanisms. Looks like more [censored] fed to an innocent public.
Anderson Copper is going there on Monday; he'll get to the bottom of this!

My prayers ar to the Japanese and to US servicemembers there.
Now Japanese say radiation levels at the damaged reactor are dropping.

Thier whole culture like China is about "saving face". I would be leery about any news about thier containment of radiation. Right now they are handing out iodine.

Yesterday I wasnt terribly concerned with the "emergency" status mentioned, as it is SOP. Now, whether there will be a large release or not, we will see... I hope not. Seems that based upon the news reports that there may be some very dishonorable Japanese after all the stories flush out.
I like to read the commentaries by people after the reports. This one was pretty good.

The core melt has already occurred. It is now about containment and that may be lost soon. I am in this line of work and have been piecing together all the information and video. If this was a hydrogen explosion like one report said. It means the zirc-water reaction has already occurred. Fuel cladding material when it melts reacts to produce hydrogen. This is an exothermic reaction that produces even more heat than the decay heat. This is what happens during a core melt. The report I heard mentioned that it was the outer containment that exploded. That means the hydrogen has leaked past the primary containment structure and reached its explosive range in the secondary containment. All that was necessary was a spark. Hopefully the thicker primary containment building is intact and will hold most of the core material now called corium (molten core mass). Containment pressure is probably high and is being released to prevent primary containment breach. This is accounting for the increased radiation around the plant. Melt has occurred just keeping it contained now.

Wow,this quote worries me on so many levels. "And the AP adds that: " 'meltdown' is not a technical term. Rather, it is an informal way of referring to a very serious collapse". A meltdown is absolutely a technical term. Control rods are used to absorbs neutrons. These rods can be inserted into the core to slow the reaction down. A meltdown is when the temperature gets so high that these control rods melt and taking aways to only way to control the nuclear reaction. This is a point of no return where efforts must turn to burying the core in concrete.
Wake up Mark!!! If you don't understand nuclear power, talk to someone who does.

If news reports start showing helicopters dumping material into the explosion site we can be sure that a meltdown occurred.
Not sure what really is the case. Im not a nuke expert. I just hope the truth is flowing...
