Reactor meltdown possible in Japan.

TMI had a partial meltdown, but no container breach? If so, it would seem different scenario being played out here.

Tmi had two big differences. First the outer containment building was never breached. A hydrogen bubble was detected and although there may have been an explosion it was nowhere near as severe as these.

The amount of time cooling was lost at tmi and the amount of water lost was tiny in comparison to the reports here and a ton of the core melted then. Really I hope the main container has not been breached otherwise this is a disaster unfolding.

live stream of a Geiger counter in Tokyo. Pretty cool.

Also, TEPCO is going to have a lot of explaining to do. They keep saying "we have it under control", when they clearly don't. Reporters are furious with them.

TEPCO has a very long history of concealing things.

we must find out if the chambers are in tact. If they are and cooling can be applied.....sea water......this will likely be ok......if No 2 is leaking from the chamber.....that is bad obviously. There are other containment barriers but we also need to find out what the explosion damage is......

press cnf in 30......

Lol I read that as confrontation and I think that's probably what it's going to be.

Actually Edano has been for the most part straightforward.

Despite all this need for instantaneous information they needed time to assess and if it's indeed dire or that bad I'm sure he will acknowledge it.

Guy doesn't look like he has slept since Friday though.

Reading an earlier post about the comments being made by Tokyo Electric Power, it is important to understand something about the Japanese culture. If they make a mistake, they say "I am sorry. We made a mistake" and then they move on, put it behind them. I certainly read that from some of their statements... not that this is the end of the story, but it reflects the kind of comments they are making to the press.

Read about the November 22, 1968 Japan Airline Flight 2 (DC-8) that landed short of SFO piloted by Captain Asoh. His apology was called the "Asoh defense" and was a learning experience for Americans about the Japanese culture.

I've been to Tokyo and worked within the Japanese culture for 2 years. When they realize they have "offended," you are correct, they apologize very quickly by saying "Gomenasai," with a hand up, and one or two head nods. After which, they rush off as quickly as possible, appearing quite embarrassed.

I was very surprised to hear the Japanese press dig in, and push aggressively (very difficult for that culture) for a reason for the "Gomen'" offered.

I also realized that in this case, the apology was quite likely preemptive, for withholding the level of the crisis, in the hopes that they would be able to regain control, and save face.

If people read the history of tmi it will put a ton of this in context. The amount of time coolant was lost and the degree to which it has been lost is far greater this time. Koyodo reports almost 150 minutes of total rod exposure versus tmi.

It's also interesting to read about the melting of fuel, byproducts and almost explosion at tmi. Goes to show how much more severe this is.

The event tv show on NBC dealing with nuclear meltdown. Ouch NBC...Charlie sheen'esque timing

While I know they have to be forthcoming with the latest info (especially now that the press is really peeved) they have to be careful at the same time and I'm sure it's posing a dilemma. Otherwise they pose the risk of creating complete panic and chaos in Tokyo which would make things even more dangerous if it isn't warranted. So far the Japanese people have shown to be one hell of a resilient nation. Nerves have to be incredibly frayed at this point though.

Kind of important as a meltdown can occur with or without vessel containment. If the vessel containers are breached then yes, that's real bad. Looks like our MSM networks are on short supply of nuke experts these days.

The reports I am hearing point to cracks/leaks in the reactor vessel. The explosion happened in the bottom of the concrete containment structure just below the reactor vessel.

For those asking "How many containment systems/wall are there...

1. Outer building wall (which blew off #1 first).

2. Containment building made of thick re-enforced concrete and designed to "hold" a melted core, but nobody knows because no core has ever made it through on a BWR reactor.

3. The reactor vessel is where all the reaction happens and is where the primary coolant circulates to control temperatures/energy. These are made of 20 cm stainless steel. They have vents and safety systems built into them to prevent over pressurization. The reactor vessel sits inside the containment building which is covered at the top by the outer building.

For the pressure in the reactor vessel to be at normal atmospheric pressure indicates a breach/crack.

Someone else asked why these things are built so close to one another. There are a lot of reasons. From a safety point of view though, it might be wise to reconsider "clusters" in earthquake or Tsunami. Another option would be to build re-directing walls between the ocean and the plant that would re-direct/canal a tsunami away from the plant. Probably an option plants will consider now.

Its an amazing society. If the same thing happened here half the military would have to be used to prevent looting instead of rescue and recovery operations.

I second your statement. The Japanese culture could definitely teach American society a thing or two about what it really means to be a community. Their peacefulness and eagerness to aid anyone, is gently inspiring.
