Hi @nancy - here are some nice pretty 5&6 temp graphs - no, I don't know what they show! www.tepco.co.jpby hudebnik 5/20/2011 12:17:37 PM
@Ralph Unger nope, look at the corner of #2, there is a small pipe that runs up the side.by Nancy 5/20/2011 12:24:37 PM- @hudebnik Thanks, I am a tad paranoid about #6 after TEPCO said it was at risk of flooding the cooling systems.by Nancy 5/20/2011 12:26:06 PM
- @nancy - I'm paranoid about EVERYTHING!by hudebnik 5/20/2011 12:27:17 PM
Lisa P. Jackson needs our support! She is defending the EPA. Or what is left of it....by Ralph Unger 5/20/2011 12:29:53 PM- I think we can infer that #5 is temperature cycling over quite a wide range, 45-70C, #6 is cooler, 25-50C. But what goes down as the temperature rises? My guess is that the first of the 2 traces for each reactor is water temp (I think I recognise the Kanji character for water in the legend) the second is some other sensor (?). Any Japanese speakers on the board?by hudebnik 5/20/2011 12:32:57 PM

- Google translate works wonder for the kanji you dont know :) I can only read water, temperature and the katakana for poolby Jocke_Jensen 5/20/2011 12:36:26 PM
- Unfortunately I can't get Google to tx stuff from Tepco's PDFs because they have set the permissions to deny copying.by hudebnik 5/20/2011 12:38:23 PM
- @hudebnik What I am keeping an eye out for is any temp spikes that don't routinely go back down or sudden black out of data on #6 indicating the reactor systems might have been flooded out. How they let #6 fill up with 6 feet of water is just beyond me. One would think preventing the other 2 from melting down would be a priority in water management decisions.by Nancy 5/20/2011 12:38:35 PM

@Nancy I think it is a (highly contaminated) ground water issue. Several weeks ago the mentioned pumping out water from #6 and referred to it as "subdrains". Groundwater level ther is high, and is going to continue to be a factor. I brought up real early, that they have groundwater pumps working around the clock, in normal times.. www.asahi.comby RBeaner 5/20/2011 12:48:44 PM- @hudebnik TEPCO will not defeat me. :-) It just annoys me that they lock down their documents to that extent. I had one I could not save and reopen because they put a password on it.by Nancy 5/20/2011 12:56:07 PM
- @nancy - they won't defeat me either. I was very pleased to spirit the historical reactor docs from them before they had realised what they had done. As we used to say at the BBC after an especially big c**k-up, "Assistant Heads will roll!"by hudebnik 5/20/2011 1:02:39 PM
- @hudebnik Elaine found tons of documents doing a bit of reasearch. We saved anything that looked of value. TEPCO was erasing documents over a month ago. So anything found of use keep a copy! We can figure out how to share and distribute later. Making copies before TEPCO deletes them is probably the biggest issue right now.by Nancy 5/20/2011 1:09:28 PM

For 20 May NISA reports, they have filenames of the form "pdfs\.pdfs\.pdf" instead of "pdfs\.pdf"by Markfm 5/20/2011 1:16:24 PM- New news from Japan via some of the reporters I have contact with.
#3 is having heat issues, they intend to water more. Estimate is they will be out of water holding capacity in 1 week. No plan what they will do, sea release may happen again.
Worker conditions are getting worse, the upcoming summer heat is a major concern with no current plan. If we have brainstorming ideas on this we should gather and pass on.
Building 3 is having structural issues. They are warning workers about falling objects but have not rated it as fragile yet as in needing a new plan but it is a concern.by Nancy 5/20/2011 1:26:14 PM - I hate to post and fly. I have to leave, should be back in about 6 hrs and can field questions related to the post below.by Nancy 5/20/2011 1:26:37 PM
- @markfm - well found! Typical Homer-style efficiency there, then. So #1 temp falling but pressure still rising, #4SFP pretty hot...by hudebnik 5/20/2011 1:27:24 PM

#3 warning about falling objects, but not yet calling it fragile -- yeah, right. ("Pieces are falling off, but don't worry")by Markfm 5/20/2011 1:36:21 PM- @Nancy:
May be you have missed this...
@estacion and @Nancy: The TEPCO plan was for the water supply and drainage system at Daiichi NPP and the Japanese for deep well indicates it is a well that "goes down to the water table."

No.1 reactor has 4.2 meters of contaminated water
Workers have confirmed that more than 4 meters of highly radioactive water has flooded the basement of one of the reactors at the Fukushima Daiichi nuclear power plant.
The plant's operator, the Tokyo Electric Power Company, sent workers inside the No.1 reactor on Friday as part of preparations to install a cooling system to stabilize the reactor core.
TEPCO suspects that the reactor's fuel rods have melted down, creating holes in a pressure vessel and damaging the reactor's containment vessel.
Contaminated water is apparently leaking from the holes. Under a revised plan announced this week, the utility plans to decontaminate the water and circulate it to cool the reactor core.
Two workers who went into the building on Friday morning stayed there for about one hour, and confirmed that water in the basement was roughly 4.2 meters deep. That's slightly more than a week ago, when TEPCO first confirmed the existence of water there.
4 other workers later took over and spent about 90 minutes on the ground floor using a gamma camera to measure the spread and densities of radiation.
TEPCO plans to use the findings to decide how to install the cooling system and set procedures for workers to follow.

Not sure where #4 stands -- I thought they were supposed to have put in permanent temp and water level sensors several weeks ago, but don't seem to be providing that info in the summary reports.by Markfm 5/20/2011 2:00:00 PM

March quake mechanism
A Japanese scientist says the March 11th earthquake and tsunami were caused by distinctive movements of nearby tectonic plates.
Associate Professor Satoshi Ide of the University of Tokyo's Graduate School analyzed data from seismometers around the world. He studied the movements of the descending Pacific plate, or the ocean plate, and the overlying North American plate carrying eastern Japan, at the time of the quake.
Ide found the quake began with the North American plate sliding relatively slowly along its boundary with the Pacific plate, off the coast of Japan at a depth of about 20 kilometers.
The sliding movement spread in the direction of the coast for about 40 seconds, sending strong tremors across northeastern Japan.
Then, about one minute after the quake began, the displacement accelerated near the Japan Trench, causing the North American plate to slip as far as 30 meters. Ide says this resulted in lifting vast amounts of seawater, triggering the massive tsunami.
About 90 seconds after the start of the quake, the plate slid again deep beneath the seabed near the coast, triggering another wave of strong jolts.
Ide says the findings show that the movement of the North American plate was greater than the stress accumulated around its boundary with the Pacific plate. He says he will next explore whether similar events could happen in other areas.
