I'm seeing a green tint to it, and my daughter said "fire" right away when I asked what she thought it looked like.by M.I.A. 12/1/2011 3:56:09 PM
The fire is getting bigger. I have seen absolutely no action on the TEPPY cam they have to know about it..by lillymunster 12/1/2011 3:56:37 PM- For how big it looks on TBS there doesn't seem to be huge amounts of smoke on Teppy.by lillymunster 12/1/2011 3:58:27 PM
What do you make of the fact, although we cannot see well enough to be sure, that there doesn't appear to be lights being put upon it to illuminate a response?by bo via mobile 12/1/2011 4:00:34 PM- can someone please give a screenshotby DT 12/1/2011 4:00:58 PM
by Panserbjorne9 via I1200.photobucket 12/1/2011 4:05:44 PM- Flames seem to be flashing larger now.by bo via mobile 12/1/2011 4:08:26 PM
- @bo agreed; slightly but definitivelyby Panserbjorne9 12/1/2011 4:09:16 PM
- I'm seeing a perfect round circle in the midst of it, esp. when it's died down. Could they be burning hydrogen from the end of a pipe?by M.I.A. 12/1/2011 4:09:28 PM
- One would think an urgent response would be necessary.by bo via mobile 12/1/2011 4:10:02 PM
- @M.I.A. I surely can't say technically, but one would think that if it has come to that it is an indicator of a deteriorating situation in terms of the possible hydrogen buildup.by bo via mobile 12/1/2011 4:11:31 PM
- @M.I.A. i was wondering the same thing- is this a (somewhat) controlled burn of some sort... but it would then imply something's upby Panserbjorne9 12/1/2011 4:11:47 PM
- ....lol, Bo, dittoby Panserbjorne9 12/1/2011 4:11:57 PM
- Yes it is really weird that there is no response. We see action and people doing things when there have been steam events or night maintenance.by lillymunster 12/1/2011 4:12:07 PM
- Could hydrogen be control burned in some way?by lillymunster 12/1/2011 4:12:30 PM
This is the desalination truck. Posting to give an idea what the temporary equipment rigs look like www.tepco.co.jp
by lillymunster via Tepco.co.jp 12/1/2011 4:14:33 PM- But I do agree there does appear to be a "point source."by bo via mobile 12/1/2011 4:18:11 PM
- Seriously though, if they are taking to burning off the hydrogen then an explosion must have seemed likely.by bo via mobile 12/1/2011 4:20:14 PM
- From my times playing with fire coloring, I know that the color of the flame indicates the temp. Blues and greens are usually closer to the ignition source, and are photons released from higher heat. Sodium burns a bright yellow...by M.I.A. 12/1/2011 4:22:34 PM
- Given that it hasn't moved, has only gotten slightly larger in the time we've been looking, it does appear somewhat 'controlled'. It would have started raging or went out for lack of fuel otherwise.by Panserbjorne9 12/1/2011 4:23:00 PM
- The green I am seeing seems to show up when it wanes and I see it in the left side of the fireby lillymunster 12/1/2011 4:24:43 PM
- A pure oxygen-hydrogen flame is ultraviolet and virtually invisible too the eye, but with dust/carbon and sodium in it...by M.I.A. 12/1/2011 4:25:00 PM
- The lack of a response would also support the notion that this is planned. Was it 3 or 4 that was having the dangerous hydrogen buildup?by bo via mobile 12/1/2011 4:25:13 PM
- I keep going back to "is this a warning light" or something similar. Then I remembered, we can't see the 1st story of the buildings on TBS due to the trees and reactor level being down a small hill. Whatever that is, is at least 1 story tall.by lillymunster 12/1/2011 4:26:06 PM
- TEPCO's recent press release talks about hydrogen injection changes at 1-3. Hydrogen would be a non issue at 4 due to no fuel in the core. Off to try to find what units had the hydrogen spike issues recentlyby lillymunster 12/1/2011 4:27:26 PM
- Just looked it up and confirmed info on the colors I mentioned. Found Barium emits green. www.webexhibits.orgby M.I.A. 12/1/2011 4:29:06 PM
- newest report Dec 1 (unit 2)
At 1:45 pm on November 30, we started nitrogen injection to the Reactor
Pressure Vessel. At 2:47 on the same day, as we confirmed nitrogen
injection had not increased, we temporally stopped the operation. We are
continuing nitrogen injection into the primary containment vessel. The
inspection thereafter revealed that the valve which was not described in
the operation manual was not open. At 10:46 am on December 1, we
restarted the injection operation. At 11:00 am, injection amount reached
the scheduled amount of 5 m3/h. Along with this operation, in order to
balance the injected amount of nitrogen into the Reactor Pressure Vessel
and the Primary Containment Vessel of Unit 2 and the exhaust amount from
the gas management system, the exhaust amount from the system was
adjusted from approx. 22 m3/h to approx. 34 m3/hby lillymunster 12/1/2011 4:29:33 PM - Unit 3
At 4:26 pm on November 30, we started operation to inject nitrogen into
the reactor pressure vessel. At 4:40 pm on November 30, injection amount
reached the scheduled amount of 5 N m3/h.by lillymunster 12/1/2011 4:30:22 PM - So all unit 2?by bo via mobile 12/1/2011 4:30:30 PM
- Unit 3 has had hydrogen issues also. Unit 2 has had struggles with the ratio, IIRC unit 3 also has had struggles with keeping the ratio right.by lillymunster 12/1/2011 4:33:03 PM
- TEPCO mentioned the other day the lowered water volumes being put in to create more steam to counter hydrogen.
This was after the whole talk of increasing nitrogen at all units.by lillymunster 12/1/2011 4:38:08 PM - I hate to say it, but I am off to bed. I'm in the middle of the Hiroshima Peace Film Festival and very busy everyday and night. Hopefully it will be out, or look the same when I get up in the morning. Thanks to all and especially to @lilly for all of the background data. Mata ne.by bo via mobile 12/1/2011 4:38:50 PM
- nite bo!
@all
From recent press release about their additional nitrogen injection work from last week
Following the implementation, it is expected that relatively high concentration
of hydrogen inside reactor pressure vessel may pushed out to primary
containment vessel. Therefore, the amount of nitrogen injection for Unit 3 will
be increased from 14Nm
3
/h to 28Nm
3
/h at the same time since the injection
amount for Unit 3 is small compared to Unit 1 and 2
www.tepco.co.jpby lillymunster 12/1/2011 4:40:18 PM - This from Oct talks about TEPCO ejecting hydrogen from a pipe to prevent explosion. enenews.comby lillymunster 12/1/2011 4:41:59 PM
- The fire location is situated near but past out into the road from the base of the vent stack. I don't know if they have any intact venting in that area to feed a flame source if they were purging hydrogen?by lillymunster 12/1/2011 4:43:16 PM
- Still no changes on Teppycam. I'm thinking the controlled burn/venting may be what is happeningby lillymunster 12/1/2011 4:55:26 PM
- Question: if it is a hydrogen burn off would there be much smoke?by lillymunster 12/1/2011 5:06:50 PM
- @lillymunster Short answer is no, butand more
lots of factors- carbon content, efficiency of burnby M.I.A. 12/1/2011 5:09:10 PM - generally speaking, burning gases give off vapors, vice smokeby M.I.A. 12/1/2011 5:11:10 PM
- @M.I.A. If it was diesel fuel or something like a small structure there would be smoke. So this does sort of fit a burn off?by lillymunster 12/1/2011 5:11:55 PM
- Yes, I think so. Diesel would give off lots of black smoke.by M.I.A. 12/1/2011 5:14:18 PM
- A structure fire would have more reds and orange in it.by M.I.A. 12/1/2011 5:14:45 PM
- MIA what was it you said burns yellow or green?by lillymunster 12/1/2011 5:17:30 PM
- Yellow is sodium (sea salt?) and green is barium. But of course other substances also give off those colors.by M.I.A. 12/1/2011 5:19:04 PM
- I'm no expert, remember. Just chiming in to give some ideas :-)by M.I.A. 12/1/2011 5:20:14 PM
