Title: Arnold Gundersen with another update on the unfolding effects of the Fukushima disaster
Source: KPFT Houston, If You Love This Planet Radio
Date: Aug 31, 2012
Description: This week, Dr. Caldicott brings on nuclear engineer Arnold Gundersen [...]
At 12:00 in
Gundersen: That’s not clear, especially in Unit 3, how much damage is in the spent fuel pool. I think the damage in Unit 3′s pool is extensive.

Go 'Newsers&# 039;!! Folks, keep reading,...

Well you drop a 30 ton-rated-crane into the SFP and something has got to give. It not clear? It's clear to me. It's torn all to hell.

Sorry but… No Sh*t?!
The SFP crane went up in the sky like a rocket… SFP 3 turned into dust…

Smokin…I dont believe that to be the case. SFPs are not 'contained', therefore a 'prompt criticality' will vector upwards, not outwards. That is what appears to have happened. Here are some links to substantiate that probability, IMO…:

There are also rare pics on the net of what appear to be fairly intact fuel assemblies lying around and leaning on buildings/rubble, a probability substantiated by their infrared heat signature. MOX pellets were also found on the ground up to 2km away from Daiichi, which means that there's probably an amount lying on the seabed too as the blast vector appears to have been straight up, with a scattered descent. See link above. The best collection of pics that I've found are on the facebook page of Troy Livingston. Here is a link I've saved, but can't get it to connect right now. Would be great if he could post all his pics on a site that doesn't need 'membership', like FB does…
U3 exposed fuel assemblies?

Yes, Omniversling, I know it sounds cliche, but SFP #3 badly damaged? Well, NO DUH.
BTW, we had some discussion awhile back about those things which look like fuel racks lying around all over the place. Some appear to be fuel racks, and some are roof girders and steel beams from inside the structure, which were torn loose and thrown about when the thing blew sky high. Am thinking the person who posted here (Enenewser) was someone with reactor and nuke plant experience, or a nuclear physics and/or engineering degree.
If you're out there, will you please chime in on this? We discussed this last fall, or around the new year (01/12), when there were cooling problems with #2 (or something). If I recall correctly, it was the winter time and the cooling pipes (the jury rigged ones they've set up there) were freezing, and they were losing cooling. I think it was posted in the context of discussion about cooling failures (and dropping water levels) at Fuku-Dai #1 or #2.
Does anyone remember?
You might want to do a site search and see if you can pull that up. Someone posted good (and IMHO reliable) info. about those things which look look like fuel assembles. The person had said how one might distinguish the fuel assemblies from the steel beams and girders.
Just an FYI.

Dr. McCoy says, "Yes, the #3 spent fuel pool is badly damaged, but dammit Jim, I'm a doctor, not a brain surgeon!"
Report Comment
It doesn't take a brain surgeon to look at the films/videos of #3 blowing up to realize the SFP there is badly damaged. If there's much of it left, then it's a bleepin' miracle. The pics posted online shortly after showed a big, massive, gaping hole where the SFP was supposed to be. And there were three explosions. The second or third one appears to have been the SFP. Some have even said the detonation (not detonation, of which there seem to have been two, one or two before the detonation, one after?) which occured at #3 was the SFP.
Can one of the more brainy and/or experienced persons here comment on this? Someone had posted great commentary here on this subject, awhile back. Actually, there were several of you who made a very good case for multiple explosions and a detonation.
Report Comment
Sorry, that was supposed to say, some have even said the deflagrations (one or two of them) occurred separately from the detonation. The deflagrations may have caused the detonation. I think Arnie G. said the whole shebang may have been started by a prompt criticality which occured in the spent fuel pool at #3.
Am not sure which one of the explosions (deflagration(s) or the detonation) was the SFP. Whatever the big mushroom shaped cloud was, it was some massive explosion, and apparently that was the detonation.
Report Comment
I would be surprised if there is anything much of SFP3 left.
