@Dom Excellent article...thanks for posting it. Here's a good graphic from that article detailing the number of nuclear reactors in Japan: www.japanfocus.org

@Markfm Yes, this seems like the first time there will be a sustained Easterly wind.

@dean I have a tech question for you. The reactor cap, containment cap, the "steam dryer" apparatus that goes under one of the caps all get placed on the work deck when servicing the reactor. Is the placement of these items static or fluid as in they could plop the yellow cap in one spot one time and the next service put the dryer apparatus in that spot? Does that make sense?

US offers unmanned copter to help remove fuel is a neat article english.kyodonews.jp

ty Nancy.. I'll do the best I can without a blue print of the way the steam dryer mounts into the reactor on the bottom.. I would think that there would be a mechanical attachment, then the reactor vessel top has a series of studs that the top head is lowered onto, then the many many nuts on the studs... some sore of machine that is like a SPANNER WRENCH to sequentially tighten the nuts on the studs ... then the yellow concrete containment cap with I think we've learned is a solid connection to the containment.. it has to withstand some where around 70 pounds. and finally the top caps.. so,,, I don't see the yellow cap being ploped.. however, if an explosion of the magnitude that we've seen happen it could blow the top of the reactor vessel off and then push up the yellow cap and top cover..

New cryptome images from this morning tweaked and zoomed the best I could. Really bummed by the low quality drone images but some new views. www.houseoffoust.com
by Nancy 4/16/2011 11:31:34 PM

Nancy.. from what we've learned do we think the yellow dome and reactor top head have been blown ott.. and the top plate..
by dean 4/16/2011 11:31:54 PM

@dean I was wondering about when they do service. They place the caps on the work floor in various places. Do those items have a designated place and can only be stored there or can they just put them whereever out of the way? So one time the yellow cap is in the corner and the next they put the dryer there. This image may help explain what I am trying to ask. www.houseoffoust.com

I had been going through interior images today, brought up the question.
by Nancy 4/16/2011 11:37:28 PM

@Nancy : each part has its designated place to put, but the places may vary in different reactors.
by Edano 4/16/2011 11:38:21 PM

@Edano but they will have a spot for say the yellow cap to go each time.
by Nancy 4/16/2011 11:39:21 PM

Nancy.. in most facilities ,, well at least the reactor I worked at had floor loading areas... there were lift height requirements and areas where loads could not be moved over those areas... as such.. every piece of hardware that came out.. had a designated place to store.. some times for convience , some times for the order taken off.. or other times for rad controls... I suspect it's the same at those reactors..
by dean 4/16/2011 11:39:40 PM

@Nancy : they have strict protocolls everything always the same place.
by Edano 4/16/2011 11:40:06 PM

we always had a main floor storage map that went with work orders to off load things
by dean 4/16/2011 11:40:39 PM

@Edano @dean Thanks that answered some big questions I had about the floor layouts on 3 and 4
by Nancy 4/16/2011 11:40:57 PM

Both interior images I have of 3 and 4 conveniently have the reactor cap storage spot missing.. Hoping to dig up some more photos of inside.
by Nancy 4/16/2011 11:41:46 PM

nancy.. from various photos we should see the same spots for the components.. however, there may be a difference between #2 and 3 and 4 as they were changed some on the floor plan as apposed to #1
by dean 4/16/2011 11:42:23 PM

@Nancy : it is a matter of quality management. every worker has to know where things are even when he is in another room or the shift changes. therefore strict protocols and designated places.
by Edano 4/16/2011 11:43:27 PM

@dean I am getting a very good picture of 3, should have a new page of images and explanations in a few days. 4 is a bit more of a question still.

[Good (my GMT+8) morning! Might it be advantageous if some of the relevant image pages can be organized by reactor? I think so. ~ more work ~ Thanks. - Alblee]
by Nancy edited by alblee 4/16/2011 11:44:45 PM

Nancy.. some link that had the blue print of #1 also has an explanation of how the others are different..
by dean 4/16/2011 11:45:40 PM

@dean if you find that let me know.
by Nancy 4/16/2011 11:47:45 PM

from that write up .. what was done..the location of the heads etc. could be different
by dean 4/16/2011 11:48:30 PM

from what I can tell from those pre-earthquake images is the refueling crane straddles the round reactor well. That is helping figure a few things out
by Nancy 4/16/2011 11:48:33 PM

@dean I think they are.
by Nancy 4/16/2011 11:48:54 PM

yes... it has to be able to move above the vessel to be directly above the fuel or other hardware removed like the shroud
by dean 4/16/2011 11:49:26 PM

I need to take a break.. dinner time.
by dean 4/16/2011 11:51:52 PM

Thanks dean and edano that was very helpful in sorting thing out
by Nancy 4/16/2011 11:53:16 PM

@Dom, I'm really appreciating the article you posted from www.japanfocus.org "March 2011 is set to mark a caesura in Japanese history comparable to August 1945: the end of a particular model of state, economy and society, both marked by nuclear catastrophes that shook the world…"
by Dan 4/17/2011 12:01:41 AM

@Dan: I'm glad youve found it as interesting as I have. It seems to me that the article nicely wraps-up much of what has been discussed here (which I follow, may I say, religiously since Reuters) and bluntly presents unpalatable issues: "leaders chose to see the most dangerous substance known to humanity, plutonium, as the magical solution to the country’s energy security. While international attention focused on the North Korean nuclear threat, Japan escaped serious international scrutiny as it pursued its nuclear destiny. One bizarre consequence is the emergence of Japan as a greater nuclear threat to the region than North Korea."
by Dom 4/17/2011 12:14:50 AM

@Nancy I'm starting to think that the drone images released to the public are poor quality on purpose. I think the real purpose of the drones is to collect heat and radiation readings. If there are any high-quality images from the drones I don't think we'll ever see them. Nice try, though...appreciate your work.

The data is a little weird on the EPA web site right now, seeing as they are supposedly showing data posted 4/17 through 4/20. WTH?

@Nancy, in the sixth pic of this series cryptome.org we may see a piece of the concrete plug on the floor of #3 at front left.

@Dom @Dan Thanks for the Japan Focus article. The history combined with current information makes for excellent reading that I would reccomend to everyone here.
The section on the reprocsessing at Rokkash chilled my blood...
" Under current (to March 2011) plans, fluids containing low levels of radiation were to be piped several kilometres out into the Pacific Ocean for discharge, the standards for effluent control having been relaxed so that Rokkasho could discharge the equivalent of the nuclear wastes of 1,300 power stations.
