@LM many timesby Jim 5/10/2011 2:08:07 PM
@all Sorry for the re-post. I just woke up and only looked back 2 pages.by LM 5/10/2011 2:09:11 PM
I'm not seeing that. 7 May RPV temps were 163/150, DW were 206/153. 8 May RPV temps were 202/152, DW were 209/158. 9 May RPV 210/153, DW 210/154. I do see Unit 2 CAMS reached 148 on 8 May, before its initial drop to 128 on 9 May.by Markfm 5/10/2011 2:10:03 PM- @Markfm Who/what are you speaking to/of ?by Jim 5/10/2011 2:12:48 PM
- Perhaps someone's doing Fahrenheit/Celsius conversion -- >300F, not > 300C. Someone talking about temps greater than 300C -- the plant parameters I'm seeing do not support it, so I wondered where the data came from.by Markfm 5/10/2011 2:13:42 PM

@Markfm Look at the 5th and 6th. I can't remember for sure what sensor it was but it was in the DW section on 3, one of the temps listed was in the 300 range for a while, had been running in the high 200's. I don't read the plant stats often enough to remember specifically what one it was.by Nancy 5/10/2011 2:15:26 PM
These are the latest temps for #3 - note how the temp in 3rd column has dropped. @bo got translation of column headings: • Title: Power meter related to temperature
1. (blank)
2. Water supply nozzle temperature
3. RPV bottom part head temperature
4. Bronze phalange
5. Temperature @ bottom of pressure container
6. RPV temperature at bolt
7. Temperature at lower part of bronze phalange
8. Release valve security 2-71D leak
9. Release valve security 2-71F leak
10. Steam/vapor isolating valve 2-86A leak
11. Recovery temperature
12. RPV (Bero or Vero) sealing
13. S/C pool water temperature A
14. S/C pool water temperature Bby hudebnik 5/10/2011 2:16:19 PM- www.tepco.co.jp is tempsby hudebnik 5/10/2011 2:16:45 PM
LoLLopezz on twitter is suggesting that the contents of the sfp are 'touching' the flange of reactor #3 and are the source of the high temp readingby elainekirk 5/10/2011 2:16:54 PM
sorry Nancy and Jim.. I lost my internet connection... @ Jim.. that brass looking thing is weird.. would like to see more of how it's used if possible .... @ Nancy.. I want to see the video..by dean 5/10/2011 2:17:12 PM- welcome back elaineby dean 5/10/2011 2:17:57 PM
- @elainekirk @dean It seems to be acting like a radiator.by Jim 5/10/2011 2:17:58 PM
- @dean #3 sfp video www.youtube.comby Nancy 5/10/2011 2:19:09 PM
- Sorry all, scribble is driving me crazy today. Let's try again! www.tepco.co.jp is the latest temp reading for #3 and the header translations are 1. (blank)
2. Water supply nozzle temperature
3. RPV bottom part head temperature
4. Bronze phalange
5. Temperature @ bottom of pressure container
6. RPV temperature at bolt
7. Temperature at lower part of bronze phalange
8. Release valve security 2-71D leak
9. Release valve security 2-71F leak
10. Steam/vapor isolating valve 2-86A leak
11. Recovery temperature
12. RPV (Bero or Vero) sealing
13. S/C pool water temperature A
14. S/C pool water temperature Bby hudebnik 5/10/2011 2:19:22 PM - It's bottom temp (flange) is around 209by Jim 5/10/2011 2:19:55 PM
- The radiation detecting crockery is becoming very useful in Japan
movapic.comby elainekirk 5/10/2011 2:20:12 PM - Other reactor temps for comparison #1 www.tepco.co.jp #2 www.tepco.co.jpby hudebnik 5/10/2011 2:21:17 PM
- @jim I think that may be a case of inter country interpretation I know that I would refer to the top lip as the flangeby elainekirk 5/10/2011 2:21:26 PM
- No sorry 173by Jim 5/10/2011 2:21:48 PM
Jim, thanks for posting the link -- I was trying to find where that data set came from.by Markfm 5/10/2011 2:21:58 PM
Repost: Updated CTBTO radioisotope measurements at Takasaki, Japan from the Center for Promotion of Disarmament and Non-Proliferation www.cpdnp.jpby Bobby1 5/10/2011 2:22:28 PM- checking out video.. dang internet connectionby dean 5/10/2011 2:23:22 PM
- @elainekirk and I took phalange to be flange, from Japanese personal translation a la Bo.by Jim 5/10/2011 2:23:48 PM
- @LM Tepco says new iodine in the #3 SFP comes from the #3 reactor. Recent fission in #3 is also supported by the Takasaki data.by Bobby1 5/10/2011 2:27:23 PM
The first of my two RT interviews tonight: www.youtube.comby bo 5/10/2011 2:28:00 PM- @Markfm this Japanese TEPCO page www.tepco.co.jp has more data than appears on the English pages. Google makes a reasonable translation job. Down under the apology box are the links to reactor temps and pressures. The linked PDFs are updated every few hours so the page needs to be refreshed to pick up the latest link. @bo kindly got the column headers translated.by hudebnik 5/10/2011 2:29:27 PM
- @bo You're becoming quite the celebrity :)by Jim 5/10/2011 2:30:00 PM
- that video is unbelievable Nancy.. good find,,, wow,, trying to comprehend the magnitude of that explosion/detination..by dean 5/10/2011 2:30:00 PM
- I would like to hear what bo didby dean 5/10/2011 2:30:36 PM
- @dean It seems odd how 3 is so full of debris yet 4 that had reactor parts stored in the pool looks so orderly and neat.by Nancy 5/10/2011 2:30:53 PM
- that is a puzzle Nancy,. you know didn't we hear one time about speculation that some fuel was in the RPV on 4... because of the thermal image I think?by dean 5/10/2011 2:33:08 PM
- @dean yesby Jim 5/10/2011 2:34:04 PM
- @bo - that was excellent, thanks for doing it!by hudebnik 5/10/2011 2:36:15 PM
- well.. so on 4 perhaps the explosion which did the structural damage was from the fuel in the reactor that they said.. wasn't in there developing the hydrogen to cause that facility damage but not doing as much damage to the SFP.. I would have expected to see a whole lot more damage and debris in the SFP that what they showedby dean 5/10/2011 2:36:43 PM
In the video from #3 SFP I saw a leaking rod assembly, something not noticeable in vid from the SFP of #4. Anyone else see it?by Peter Melzer 5/10/2011 2:36:59 PM- @dean yes, there were a couple of thermal images that showed the RPV well being hot and some were wondering if there was fuel in it or parts of fuel etc. I noticed something in the paper I am reading. It mentions the control rods being inserted on #4, I didn't know if that was a typo. Would there be a reason to have the control rods up in an empty reactor?by Nancy 5/10/2011 2:38:36 PM
- @Peter - I found it hard to make out anything definite apart from the concrete and steel wreckage. Is that a dosimeter on the canister in the video? Can anyone read it?by hudebnik 5/10/2011 2:38:56 PM
- @bo Great interview, bo!by Bobby1 5/10/2011 2:39:11 PM
- @Peter Melzer can you let me know what time mark in the video it is and general part of the picture? I can grab a screen shot.by Nancy 5/10/2011 2:39:17 PM
- @Any progress being made of a forum, this chat chit has about had it. It's good for certain things but this confusion is getting old.by Jim 5/10/2011 2:39:26 PM
@Nancy : well, yes. there must have been a cold shutdown before opening it and getting the fuel out. control rods must be in.by Edano 5/10/2011 2:40:27 PM- that #3 video why are the concrete chunks rounded concrete doesn't break into pebble shaped chunksby elainekirk 5/10/2011 2:41:00 PM
- also, control rods must be in before refueling.by Edano 5/10/2011 2:41:35 PM
