CNN An 8.8-magnitude earthquake has struck Japan

So, Tepco is really good at covering up the "accident" (everything's under control) ...

yo, you do realize that is a cooling tower in your sig, and doesn't necessarily have anything to do with nuclear power generation?

So it's misleading, much like your signature.

French nuclear agency disagrees with Japan's assessment that Fukushima is a level 4 incident on the INES scale and says that it is rather a 5 or 6. This would make it as bad or worse than Three Mile Island without reaching Chernobyl levels.

The US has been surpassed by the Japanese once again.

From plants based on US designs...

It's a nuclear power plant's cooling tower. It's not a photoshop. I forget which real German nuclear power plant it is, might even be a closed-down one.
Of course, how cooling towers came to be the iconic image of nuclear power plants I have no idea, but that's the way it is. The huge Staudinger power plant (near Hanau) has a huge cooling tower looking much like that and quite visible from the motorway, and lots of people mistake it for nuclear. It isn't.

The famous photos of Three Mile Island, though I grew up 3 miles from a coal plant with cooling towers.

[Bunwahaha [still dunno why, but well, so be it]]

In other countries I don't know, but in France, I found rather impressive how it quickly went on 'we should go out of nuclear right now!!!', especially when you come to think about the 'huge' oddities that such a quake or a tsunami happen in France, it looked like the quake suddenly put  the fancy Nippon archipelago in front of Brest (which would be wonderful). Well, the way politicians dealt with Chernobyl when it happened (a mix of contempt, shallowness, and ignorance) certainly made people more 'radioactive' about those questions too. Also, I found the position of the French nuclear agency rather daring. French should actually begin to figure out that all of this is happening in Japan now.

About the quake, and especially the tsunami, very impressive pictures actually, very impressive things that happened then, very impressive in the action, and very impressive in the afterward. Such pictures, and especially coupled with a nuclear threat, would fuel all kinds of doom sayers, but whatever, just wish the best to all people involved in that.

Another explosion.

It's over, they're out of pumps. Total meltdown of all 3 reactors is now all but guaranteed.

Not unexpected.  Has the reaction stopped.

Now there seems to be a higher radiation leak.

The suppression pool of No. 2 was damaged, they are talking lower pressure in containment. I guess that means the rods are leaking out into the environment. That would be a Chernobyl style situation. The other two reactors are probably still melting, if they haven't melted already, but anyone going into the area to work now will be exposed to high amounts of radiation.

They are evacuating some plant personal. 

2.7 of the fuel rod is now exposed.  Fukushimaed!

[Beet]

Yeah they are totally screwed. Hopefully the entire Tokyo metro won't have to be evacuated, that is the largest city in the world. They literally have nowhere to go. I think this is a bigger event than 9/11 or the Egyptian revolution, even.

I would really like to know what happened though, because we really have no clue, TEPCO wasn't really telling us the truth. It's concrete block time.

They have radiation detectors around Tokyo.  Still reading normal but starting to tick up to the north.  It is next to impossible to evacuate the northern prefectures that are virtually destroyed.  There will be a greater demographic shift than with Katrina.

Now, if the pile spreads physically, will that slow or stop the reaction?

[Beet]

No idea, none of the so-called experts on TV even here have been really explaning what a worst-case scenario would look like in detail. They have all been dancing around it.

Are you saying there could be a nuclear explosion if the meltdown doesn't stop the reaction?

No, I'm asking that if the density of the melted core changes, i.e. it becomes less dense, will the reaction stop?

It would certainly make sense. Plus, exposure to environmental temperatures should gradually lower the temperature inside the ruptured containment vessel. But I'm using 6th grade science here.

As am I (plus my snow removal techniques). 

You could accelerate the cool perhaps, with liquid nitrogen.  The T-2 method.

Or liquid helium; it won't react.

I feel like that would be too cold too fast, would it make it worse?

If the containment vessel is breached, it won't make to much of a difference.  Instead of liquid nitrogen, liquid helium?

[Swing low, sweet chariot. Comin' for to carry me home.]

you couldn't transport enough liquid he or n in time. basically, it needed vast amount of liquid coolant continuously flowing through it.  since they were down to one pump, they've simply been switching back and forth between the 3 reactors to try to end up with a partial meltdown of all three instead of a full meltdown of one or more.

There is with a breached containment unit.  If there is a meltdown, the temperature will start dropping as the core is exposed to the atmosphere, it the reaction stops.
