@ lilly.. Peter had composed a letter in response to NRC and I said I would look at the second part.. can I mail this to you so you can forward on for review?
by dean 6/26/2011 1:51:25 PM

@dean Email me what you have. I can add it to what I have so far and put it up for peer review.

Going back through older fuku images today looking for missed signs of the fissure Elaine found. Noticing how upright buildings and towers seem in those images 10 days after vs. images in June.

ty lilly.. I layed down last night and thought.. I just hadn't put enough into my response so I redid it and feel better now
by dean 6/26/2011 1:54:19 PM

sounds good lilly,, hey, did you determine that the #1 stack is tipping?
by dean 6/26/2011 1:54:54 PM

@dean Toshiba are sturdy and reliable. I don't know the brand of Lilly's laptop though. I've had this Satellite for 5 and a half years, I've dropped it, I've spilled beer on it, water... never had a problem.
by Pedro Jesus 6/26/2011 1:57:39 PM

@dean Not for sure. I think it may be. There is a possibility everything in that line is at an angle. We knew that the land moved and sunk. Now that fissure that we know about is sort of in line with the things that have tipped or sunk.
by lillymunster 6/26/2011 1:59:11 PM

@Pedro Jesus My current one is an HP. I had a few Toshiba before that, they are pretty durable. Handed them both down to the kids to use and they didn't manage to destroy them. :-)
by lillymunster 6/26/2011 2:00:05 PM

see you all later
by dean 6/26/2011 2:07:05 PM

@lillymunster There have been some know issues with hard drives on HP in the recent past but I think they have fixed the problem. Fingers crossed for yours.
by Pedro Jesus 6/26/2011 2:09:18 PM

@Pedro Jesus I was smart enough to buy a business class laptop. Some of the consumer models they sell at retail stores are really low quality and have thin plastic parts. Have not looked to see what brand/model hard drive is in this one.

Internal radiation exposure found in all 15 people surveyed in Fukushima
HIROSHIMA, June 26, Kyodo
english.kyodonews.jp Morning all!
by LM 6/26/2011 2:24:34 PM

@lillymunster It's funny that the best Toshiba are not the business class but the gaming class. Completely different orientation. Toshiba has just released the new Qosmio X770. It looks awesome. But I'm still more inclined to the X500 series because the screen is slightly wider (18.4"). The new Qosmio comes with a 17.3" screen.
by Pedro Jesus 6/26/2011 2:24:44 PM

@LM Any idea on details (I hate that Kyodo blocks news stories)? Wondering if these are residents rather than workers. Concerning all of a survey batch had internal exposure.
by lillymunster 6/26/2011 2:31:32 PM

All four reactors steaming in TEPCO cam now.
by estacion 6/26/2011 2:32:45 PM

@lilly It bugs me too. From the wording I'm thinking it might have been a resident survey. I'm sure we'll find out soon. Did you hear about today's story on the boric acid added to 3 yet?
by LM 6/26/2011 2:33:43 PM

@LM I saw it a few pages back. Why were they not adding boron anymore?
by lillymunster 6/26/2011 2:37:12 PM

@Lilly I wondered the same thing. I guess they either weren't or it wasn't enough...from the article it sounds like they haven't been. They are very concerned about corrosion.
by LM 6/26/2011 2:40:08 PM

@estacion guessing they are doing water injection tonight. Since they mentioned the boron going into 3. Will be interested to see if we get an EQ.
by lillymunster 6/26/2011 2:40:51 PM

@LM Dumb question, do they put boron into the SFP water during normal operation? Or is this something needed because they are using untreated fresh water? They did mention rubble in the pool jacking the calcium levels.
by lillymunster 6/26/2011 2:42:14 PM

Morning all, here is a good Japanese site discussing the plume over Tokyo on March 21, due to an unspecified event in #3: translate.google.com
by Bobby1 6/26/2011 2:42:29 PM

"Tokyo Electric Power Company has begun adding boric acid to the spent fuel storage pool of the No.3 reactor at its Fukushima Daiichi nuclear plant to prevent fuel racks from being corroded by alkaline water." I guess they didn't. A tad incompetent don't you think? I give up!
by LM 6/26/2011 2:42:31 PM

@lilly I thought it was a normal additive but I'll try to confirm.
by LM 6/26/2011 2:44:04 PM

@Lilly Found this..."A reactor is maintained critical during normal power operations. In other systems, such as a spent fuel pool, mechanisms are in place to prevent criticality. If such a system still achieves criticality, it is called “re-criticality”. Boron and other materials, which absorb neutrons, are in place to make sure that this re-criticality does not occur. The added neutron absorbers substantially increase the rate of loss of neutrons, to ensure a subcritical system." mitnse.com
by LM 6/26/2011 2:47:37 PM

@LM They have metal clad panels with boron inside, the rods are put inside those in the SFP. Not sure if boron as a water additive would be used though since the water between the SFP and reactor mingle when they flood both to move fuel. Maybe keeping the water at the right balance in the SFP avoids the corrosion?
by lillymunster 6/26/2011 2:55:45 PM

@Bobby1 Great link, Ty!!
by estacion 6/26/2011 2:56:08 PM

If boron is added to prevent re-criticality, what does this have to do with corrosion? Doesn't it really mean that they think re-criticality is happening in the #3 fuel pool?
by Bobby1 6/26/2011 2:56:29 PM

@Bobby1 Hi Bobby! Interesting. Mar 20-21 was when 3 went to atmosphere pressure. IIRC someone mentioned some rad spikes on those days in the area of the plant.

It would depend if boron is acidic it could be used to swing the water back to a neutral PH. I have to do things like that with our aquarium because our water is horrible. Let me go look at boron properties...
by lillymunster 6/26/2011 2:57:52 PM

Boric acid (what they are probably using) has a ph of 5.2 so it could logically be used to bring the ph to a more neutral level. They said the water was too alkaline.
by lillymunster 6/26/2011 3:02:33 PM

@Lilly @Bobby1 I think they're they're pumping up the boron to neutralize the alkaline environment..as boron is an acid...with the added benefit of criticality suppression if the corrosion gets bad enough. I'm not an expert. I did find this interesting article on corrosion prevention and mitigation. www.ocvreinforcements.com
by LM 6/26/2011 3:05:03 PM

@lillymunster Well, since there have been iodine spikes on a regular basis since April, and Tepco has not said a word about them, their published reasoning is questionable. Actually, it's better that re-criticality is occurring there rather than the corium blobs, because that would mean the blobs are not cooling down.
by Bobby1 6/26/2011 3:05:20 PM

@lillymunster @Angie : yes, only keep it running while i am in vacations. the plotter works automatically.
by Edano 6/26/2011 3:05:35 PM

@Edano what kind of intervention would we need to do if something crashes? Or just make sure it is still feeding? I am assuming the files you put on my server has the source location. I would hope TEPCO wouldn't change the feed in that time so shouldn't need anything other than making sure it is still posting right.
by lillymunster 6/26/2011 3:12:29 PM

@lillymunster : nothing to intervene. just keep the proggy running.
by Edano 6/26/2011 3:13:34 PM

@Edano can do. :-)
by lillymunster 6/26/2011 3:13:48 PM

@lillymunster : your screen is > 1300 pixel wide ?
by Edano 6/26/2011 3:14:42 PM

@Bobby1 I have not been tracking the rad readings in detail lately. I was curious if we were seeing iodine drop off or not. Are these the in plant rad readings or the regional ones?
by lillymunster 6/26/2011 3:14:44 PM

@Edano yes.
by lillymunster 6/26/2011 3:14:59 PM

@lillymunster i mail you :)
by Edano 6/26/2011 3:15:25 PM

@lillymunster There was a graph of the pool under #1 I saw recently that had another spike on Wednesday. But aren't the pools overflowing into each other at this point?
by Bobby1 6/26/2011 3:17:09 PM

@Bobby1 do you mean the water building up in the lower levels of the buildings? Yes that is mingling between buildings, pits etc. We should see iodine 131 dropping in comparison to the cesium levels. The difference between the two shows if it increases or is going down vs. just finding some more radioactive water. So iodine level alone doesn't mean new activity. I was thinking the other day we should be able to get enough rad reading data around the plant to tell if there is some sort of criticality happening as long as we get both iodine and cesium to read.

ex-skf.blogspot.com Newly released Tepco fax indicates amount of noble gases emitted on March 12 was 10% of Chernobyl noble gas release.
by Bobby1 6/26/2011 3:29:29 PM

@Bobby1 I tried looking at some of the rad reporting Mark has pinned. METI is in Japanese so can't read it. MEXT only does sVh. Is TEPCO releasing analysis of plant areas based on isotope?
by lillymunster 6/26/2011 3:32:05 PM

@lillymunster , gm, I saw Dean did not find much sleep, sweating over the last paragraph. We have guests today and I won't be able to do much else. Perhaps, I could read it tonight. As to organizing data, did you check on sourceforge? All applications I saw involve adding tags. As encouragement my daughter managed to pour half a can of soda over a macbook the other day. We had to remove every single key and clean under it with windex and q-tips. Was tedious, some keys still stick, but the computer works fine. Sometimes in life we are in luck, :)
