Cs-137 is the winner, 30 year half life I guess, but it is not as bad as I-131 so I guess it is a good thing. Unless it gets in your body. Cs 134 is doing OK as well.

Has anyone noticed the radiation level in #3 Drywell lately ??? S/C 5.06 x 10 Sv/h D/W 9.74 x 10 Sv/h that is really high, shouldn't be any radiation in DW unless it is getting RPV water in it or it has corium in it !!!

Just get the name Carabiner and be done with it LOL.

@ Nancy A while back you said you saw the containment cap... I thought you were watching the live video
by carabnr 5/4/2011 2:54:34 AM

@carabnr Oh, on the video saw the containment cap on #4. That is the one that was uninstalled because they are working on it. The containment cap on #3 is still playing where's waldo.
by Nancy 5/4/2011 2:55:38 AM

I think the containment cap on #4 was giving the illusion of flames because it is so light colored and the heat waves.
by Nancy 5/4/2011 2:56:21 AM

@Nancy, never seen the D/W anywhere near that high, S/C had been creeping up, I think it was a 3 something last week, now a 5 something. Something is happening in there, and it isn't good with that high of a reading.

@wtm we started seeing steam or smoke out of 3 about 2 weeks ago. Same time 4 heated up. The SFP on 3 and 4 both got hot so the assumption had been steam out of SFP. But the reactor cap on 3 will leak steam out of the reactor well also. Sure sounds like something is not well in the bottom though. I would guess with 10Svh nobody is getting anywhere near 3's containment any time soon.

So if that was a small jet (corporate/governmental Lear or whatever) taking off from Fukushima airport, heading as tight into the wind as it could and avoid the exclusion zone, then that camera could be in Tamura.

@wtm we were discussing this morning that the RPV in 3 may have not just jumped up when it reached high pressure but could have been moved side to side in the earthquake. On top of whatever the blast did. 3 is likely an epic mess inside.
by Nancy 5/4/2011 3:01:21 AM

@radioguy I thought maybe it was the drone flight but wrong shape and too close to the camera.

#2 Pressure / Temperature of the Reactor Pressure Vessel = Unknown / Stable So they still don't know what it is LOL Who makes up these numbers and graphs. www.jaif.or.jp

@Nancy, been noticing the water levels, they can't seem to fill them any higher than what they currently are now, no matter how much water they keep telling us they are putting in there. I think that some valves or piping in the RPV's and S/C's are broke, and the water is leaking out at that particular level in the units. no way it is going to get higher until those pipes get fixed or plugged. Which means that those rods have got to be melted.

Interesting that light spot in the middle of #4 is very light compared to the other things on that side of the building....W.... but the South side is bright from the sun in the south... could it be the containment cap illuminating from the middle of the building b/c there's no roof?
by carabnr 5/4/2011 3:04:54 AM

There's the big tamura, but there's a little town in about the right direction right outside the exclusion zone. at 37N26 x 140E47
by radioguy 5/4/2011 3:05:29 AM

@Ralph, somethings he lets Homer do it, ever notice the torus looks like a donut ??? aaah Donuts !!!!
by wtm 5/4/2011 3:08:25 AM

Isn't unknown / stable kinda like a little bit pregnant? Mutually exclusive?
by Ralph Unger 5/4/2011 3:08:54 AM

@Ralph, sounds like that T-Mobile commercial where AT&T guy says "Sounds right, if you don't think about it"
by wtm 5/4/2011 3:11:09 AM

Hey, it worked, I was looking at the cute girl and did not have any thoughts at all.
by Ralph Unger 5/4/2011 3:12:20 AM

@wtm I am guessing the torus on 2 and 3 are toast. There was a study where they said if the torus was too full of water a rush of steam pressure would act like a water hammer into the torus. So if a rush of steam could potentially damage it, what would the kick back of the massive explosion on 3 do? I would assume enough pressure getting pushed into the torus would torque or bow the sections that get the brunt of the force and hard enough could bend, break, the joints or break loose connections to pipes etc.

GE was supposed to fix that a few years ago. Baffles as I recall.

Tepco device to decontaminate sea water. www3.nhk.or.jp
by Scilla 5/4/2011 3:17:59 AM

@Nancy, that would be a good assumption !!!! Or it was quake damage at some point, or both. Whatever happened, it's not going to get fixed in the near future !!!
by wtm 5/4/2011 3:18:48 AM

@Ralph Unger The jumpy reactors? One of the many unique features of the GE Mark 1? :-)
by Nancy 5/4/2011 3:22:05 AM

"A further modification was made to the “saddles” on which the torus sits — basically the series of leg-like structures that support it. The construction was fortified, as was the steel, to accommodate the loads that are generated."

The required mod list on these reactors is kinda scary.
