Video from March 14, 2012, around 11:01AM, explosion in the Reactor 3 building translated by EXSKF:
At ~1:15 in
Plant Manager Yoshida at 1F: HQ! HQ! It’s bad! It’s bad!
HQ: Yes!? Yes?
Yoshida: Reactor 3, probably steam explosion, it just happened!
HQ: (in a weak, almost disappearing voice) Alright… (someone else) O..OK.. Emergency communication…
[...]
HQ: That, that is the same as Reactor 1 [explosion], isn’t it?
Yoshida: Yes, in the building, inside the Anti-Seismic Building here, we can’t tell, but a side-way shake, clearly different from an earthquake, came, and there was no after-shake like in an earthquake. So I think this is an explosion, just like what happened in Reactor 1.
At 3:20 in
HQ (Probably Mr. Komori?, executive director, making a phone call to NISA): At 11:02AM, (was that 11:02?), at 11:02, in Reactor 3, there was a possibility of hydrogen explosion, we’ve been just informed by the plant. It’s the first report…
US Nuclear Regulatory Commission transcript excerpt from March 18, 2011:
CHAIRMAN JACZKO: [...] Just go back one more time and, and look and see if you can’t come up with a, with what I would call a true worst-case scenario; namely, the worst-case that is physically possible.
TRISH HOLAHAN: Okay.
CHAIRMAN JACZKO: See if you can do that because I, I have to believe that there is no possibility in a light-water reactor design to reject an entire core. I mean, that’s basically steam explosion; isn’t it?
TRISH HOLAHAN: Yes.

In four separate scenarios, the Mark 1 reactor secondary containment system FAILED…
… Why is this design still operating around the world?
It is a known national security risk for ANY country that has one in operation. The proof only lay at Fukushima…
… Yes, baby R3 did upchuck.
Report Comment
They have lost the power to think in front of bucks at any COST!
Report Comment
Not the entire core, there is enough MOX left from the former reactor 3 to kill a lot of us. Some went up and some went down, and is now a major source of on-going contamination, killing those near and far today, tomorrow, without known end.
Report Comment
Yes. By how many years will we have?
Report Comment
Tepco should pay for the lease of these sites, which are not due to radiation may be residing. Residents should get further money for 25 years minimum lease…
Report Comment
The Japanese video reminds me for some reason of the Who's Tommy. "That deaf,dumb and blind kid sure plays a mean pinball" Except they failed in their game. A bunch of people sitting in a bunker, without any sensors, instruments or even visibility trying to run a nuclear power plant. An entire reactor just blew up and they can only guess what just happened. Tell us again how this could never happen because everything is controllable.
Report Comment
I believe it was a prompt critical moderation because that's what Arnie thinks.
Report Comment
I meant prompt moderated criticality.
Report Comment
I agree with Arnie, and I also believe that Tepco knows. A lot of sensors were operational, and there are many sensors that would point to any criticality and any increase in radiation levels.
Report Comment
Not an expert opinion:
This was not a hydrogen explosion.
This was not a steam explosion.
This was not a prompt criticality, or whatener Arnie said it was.
This may have been a zirconium/cesium explosion.
This may have been an atom bomb.
Whatever this was, Fuku3 should be studied by non Japanese (and non nuclear industry) investigators before evidence is destroyed. The results should be made public.
If this remains a mystery, shut down all nukes until the cause is known, and until we know for certain that this cannot happen again. Or thirty or fourty times more. Better yet, just shut them all down now.
