CHAIRMAN JACZKO: — the updates, and I won’t have to do that as much.

We have video footage that we believed showed containment has been violated.

MR. DORMAN: Yes, what is it, is — I’ll try to describe it for you.

From a distance, you’ve got the plants in the center.

You’ve got four reactor buildings and behind them, from the point of view of the camera, is the turbine building and then the sea, and what you see is, on the left-most, which would be the Unit 1, from the vicinity of the reactor building, you see an initial vertical pulse –

CHAIRMAN JACZKO: Yes.

MR. DORMAN: — and then a large white cloud, spread out from that reactor building, and then you have footage of a later image, where you have the three reactor buildings to the right are solid white images, and the one where the — you know, the explosion occurred, appears to be the metal frames of the portion of the building above the refueling plug and the spent fuel pool.

CHAIRMAN JACZKO: Okay.

MR. DORMAN: And based on that, our assessment is, it appears to have been an event that originated in the reactor building.

CHAIRMAN JACZKO: Okay.

MR. DORMAN: And our assessment is that there is possibility that that would — and event like that involved a failure of the primary containment.

CHAIRMAN JACZKO: Okay.

MALE PARTICIPANT: Yes.

MALE PARTICIPANT: Well, there’s no smoke. It looks like steam, or some kind of vapor.

MR. DORMAN: Or yes, the –

MALE PARTICIPANT: It doesn’t look like smoke, and there was no fire ball.

CHAIRMAN JACZKO: Okay.

MR. DORMAN: And some of that’s pulverized concrete, too.

MALE PARTICIPANT: Yes.

CHAIRMAN JACZKO: And then the IAEA piece of information we have, can you describe that to me, again?

MR. DORMAN: The IAEA, we talked to them, a little over an hour ago, from their operations center, and Mark Shafer was on their end.

We basically confirmed that they are as starved for facts as we are.

MALE PARTICIPANT: Right.

CHAIRMAN JACZKO: Okay.

MR. DORMAN: So, there — unfortunately, we were mutually unable to help each other, much.

MR. DORMAN: The other issue that we’ve raised is that the apparent mode of force for such an event in the turbine building would be hydrogen that cooled the turbine, and we don’t see any deflagration issue, in terms of –

CHAIRMAN JACZKO: Okay.

MR. DORMAN: — we don’t see any flame –

CHAIRMAN JACZKO: Right, which you’d see from a hydrogen explosion.

MR. DORMAN: Right.

CHAIRMAN JACZKO: Okay, good, thanks.

    To : Don’t eat that;
    I put this out there deliberately to wake people up, they are not testing children’s lunches for radiation, whets up with that. The government of Japan wanted to send radioactive food to third world countries, whets up with that. The Japan government does nothing proactive, do improvements after public gets after them, whets up with that. The Japan government increased the allowable back ground radiation that is allowable, this means that the food chain radiation is increased also, whets up with that. The USA, Russia and many more countries advise a 60 mile no man’s land, Japan has set a 18 mile limit, whets up with that. The Japan government has been testing some food but for the most part say it is acceptable level even though other countries receive it and reject it, what’s up with that. So if they eat less radiation hopefully they will live longer, I suspect they are already mixing the food, some people on their own by eating less produce that they suspect high in radiation and eating produce they think is absent or has little radiation. This is a hell of a state these people are in and I hope it will not get any worse. We need to give them all the help we can, I am not pleased with my government Canada as they have refused entry for Japanese people because of Fukushima, it is disgraceful. I hope this clears the air a bit as I agree 100% what you said and hope this will open some eyes as to what’s up over there.
