@Rob in SF those are older really early images before they started clean up.

@dean this is from 12/4 for unit 4: img34.imageshack.us

@xxx but what is in that spot on the floor? The part by the ? is not where the SFP is. The SFP is left of that near the end wall they are pumping water into.
by Nancy 4/13/2011 9:53:05 PM

Pretty sure they do not have special xl rods. Storage casks are 5.4m, a good chunk of space at each end taken up by various layers of the cask. Moving fuel from sfp back to the core could not reasonably have happened. They had no power, those assemblies are very heavy, and many people would be in a world puf trouble if they lied about that pool being empty.
by Markfm 4/13/2011 9:53:43 PM

@Markfm good point, no power. So what is the heat signature over there?
by Nancy 4/13/2011 9:54:23 PM

@Markfm Good point no power means no crane
by NHK Listener 4/13/2011 9:54:43 PM

We don't know the exact details xxx of what maintenance was going on the required the fuel to be removed to the spent fuel pools. it's unlikely that they would be moving anything from the time the earthquake hit up until the damage, loss of flow and makeup.... I"m just not sure on that one..
by dean 4/13/2011 9:56:18 PM

For now, i'll continue to think that a fairly cool, 30c, reading could be a bit o of residual radiation, reactor vessel contamination, a bit of left over pool water, whatever.

I feel pretty confident that the massive explosion of #3 spread all kinda of debris over to #3... perhaps some spent fuel .. how does that wound Nancy.. from what you've been able to produce

Those ir temp scales are important to watch - the meaning varies

@dean how's it goin'? I've been slaving above a console all day doing backups. Just about the time I think I have that old site figured out..it changes. Strange.
by Jim Carver 4/13/2011 9:59:08 PM

Jo.. may I ask.. how has the technical safety requirements helped
by dean 4/13/2011 10:00:55 PM

@dean If the rows on the heat images are caused by the roof trussing it could explain the rows. Then the question is what debris is causing that much heat? I will go back and re-look at side views and see if I can find anything again in that region.
by Nancy 4/13/2011 10:00:58 PM

@dean cool, well i'll just be in the background, I have to goose it every so often since it only gets about 10 pages at a time.

cryptome.org In this photo released April 12, 2011 by Tokyo Electric Power Co. (TEPCO), workers lower a panel that is used to cover the sluice gate to stop drainage from Unit 2 reactor at the tsunami-crippled Fukushima Dai-ichi nuclear power plant in Okumamachi, Fukushima Prefecture, northeastern Japan.

@Nancy: got some pics for you, if you want to see them; don't know how to share them, they're quite big
by Jo Lindien 4/13/2011 10:01:54 PM

I drew some lines on that heat image to determine the mid lines of the length and width of the reactor work floor to get a better idea where the heat signature is vs the estimated location of the reactor well. Those heat signature appear to be over the reactor well or just beside it. Best guesses on reactor well location on #3 and #4 is it is just slightly off of the mid line on the long side of the building and on the mid line the short way. Will post the image in a few minutes. Not sure what to think of this though. Ideas?

OK Unit 4 here we have a shut down after high radiation alarm ion Feb 18 2007 I havent yet found history 2007- present but if we start here and I will keep trawling. Very *interesting* read www2.jnes.go.jp
Next problem April 23rd 2007 www2.jnes.go.jp

@all Some of those reuters pages are not there. It's around p.185-267 ...
by Jim Carver 4/13/2011 10:08:03 PM

www.marshield.com What happened with the shielding they had on order? This is interesting... "Borotron ® Borated PE has been used as a medical and industrial shielding material to attenuate and absorb neutron radiation." www.marshield.com
by Rob in SF via Marshield 4/13/2011 10:08:11 PM

@nancy, perhaps warm water is making its way from the SFP to the reactor. Afterall, the reactor was opened for service at the time of the EQ.
by Peter Melzer 4/13/2011 10:08:31 PM

@Nancy: here you are... testing with first one watch out !

I can't say exactly because it seems to change.
by Jim Carver 4/13/2011 10:08:45 PM

good point Peter, maybe they had the gates pulled so there was water between the spent fuel pool and the reactor vessel

@Peter Melzer how hot could run off water get? Hot enough for those red readings?
by Nancy 4/13/2011 10:10:35 PM

Peter's comment sounds like a reasonable possibility.
by Markfm 4/13/2011 10:10:50 PM

The only reading I noticed was today, and red is only 30C
by Markfm 4/13/2011 10:11:37 PM

@jo, where did the images come from?
by Nancy 4/13/2011 10:11:39 PM

@Nancy: all those are zoomed cryptome pics. You can see light reflections on something nearly spherical, looking like metal, inside the drywell concrete structure
by Jo Lindien 4/13/2011 10:12:16 PM

the green lines and text are mine
by Jo Lindien 4/13/2011 10:12:55 PM

@Jo Lindien I don't think the reactor is that far off center line of the building.
by NHK Listener 4/13/2011 10:14:36 PM

depending on what MODE of operation they were in at the time of earthquake we could determine if it was cold shutdown , refueling, maintenance all could be different levels and if the gas rubber seal gates were deflated and/or removed the exchange of warmer water and water level would make sense
by dean 4/13/2011 10:14:36 PM

@jo, will take a look at them. Was wondering if they were your mark ups or from somewhere else. The reactor well is round opening and closer to the mid-line, not the wall. This image gives a good idea. There is a rectangular well near the edge that has been mistaken as the reactor well by a couple of people & places. There are images of a section of the round reactor well on both 4 and 3 that match this image. Will go take a look at the shiny object your pointing to and see what it might be. www.houseoffoust.com
by Nancy via Houseoffoust 4/13/2011 10:15:10 PM

@Nancy: as green lines and comments make it difficult to clearly see things, I suggest you compare with the original cryptome pics to see better
