  • @Edano @Edano @Edano Sure tkes these "experts" a long time to catch up to us, eh?

  • fuku is a good proof for murphy's law.
    by Edano 11/2/2011 9:12:45 PM

  • @Edano That is so true. And it is also very reall and true that from Rueter's blog to now the nimble minds in this group have been way out in front

  • "Some nuclear experts have debated for months whether nuclear reactions might be continuing, either in the fuel inside the reactors, or in the spent fuel pools at the plant. They have pointed, for example, to the continued reports of short-lived iodine in the spent fuel pool at Reactor No. 3."

  • The engineer, who has worked at all three nuclear power complexes operated by Tokyo Electric, spoke on condition of anonymity because he did not want to be identified by his former employers. He said that tiny fuel pellets could have been carried to different parts of the plant, like the spaces under the reactor during attempts to vent them in the early days. That would explain several cases of lethally high radiation readings found outside the reactor cores.
    “If the fuel is still inside the reactor core, that’s one thing,” he said. But if the fuel has been dispersed more widely, then we are far from any stable shutdown.”

  • @Edano sounds a good explanation
    by elainekirk 11/2/2011 9:33:28 PM

  • the pellets are not tiny, normally. i wonder what could have destroyed them so early.
    by Edano 11/2/2011 9:37:27 PM

  • @Edano maybe he is speaking relatively , the debris etc is pretty big chunks that would dwarf a fuel pellet. But at the end of the day the anonymous employee could be a paid puppet trying to deflect attention

  • @Edano, Have there been Tepco reports of i131 in SFP3?
    by Ian 11/2/2011 9:40:32 PM

  • ... of course, lately.
    by Ian 11/2/2011 9:41:37 PM

  • @Ian not that i know.
    by Edano 11/2/2011 9:41:39 PM

  • @elainekirk right, we must be careful.
    by Edano 11/2/2011 9:42:40 PM

  • @Edano, right, same here. ?? I wonder what's Tabuchi's source.
    by Ian edited by lillymunster 11/2/2011 9:48:43 PM

  • @Edano, or maybe if we plowed through Tepco press releases with SFP radionuclide readings, but somehow I suspect we're not going to find any suddenly emergent i131 findings, at least in the last couple months, or that would have been news.
    by Ian 11/2/2011 9:51:01 PM

  • @Ian i think elaine did that. :)
    by Edano 11/2/2011 9:51:46 PM

  • I will check again
    by elainekirk 11/2/2011 9:52:23 PM

  • but we had iodine in rice recently.
    by Edano 11/2/2011 9:52:34 PM

  • @Edano, right, and a few other sporadic i131 reports in disparate spots. But in SFP3 would be significant beyond what might be attributed to medical waste or something else, it would prove/suggest recrit.
    by Ian 11/2/2011 9:54:14 PM

  • Tabuchi says there have been "continued reports of short-lived iodine in the spent fuel pool at Reactor No. 3." If not from Tepco where on earth would these reports come from? Internet rumors? Some shady figure in a back alley?
    by Ian 11/2/2011 9:56:52 PM

  • there is a 12.00hrs Nov 2nd data doc here it means nothing to me but you techi's may like it www.tepco.co.jp

  • Fuel rods seem to resonate at about 3 Hz tepco indicated in this picture: 4.bp.blogspot.com . If the Tohoku quake rattled them strong enough at around this frequency, they might have come apart.

    by Peter via 4.bp.blogspot 11/2/2011 10:22:29 PM

  • sorry , it is 0.25 Hz instead of 3 Hz.
    by Peter 11/2/2011 10:24:40 PM

  • @Peter oh now that is interesting

  • Ian, who is Tabuchi? The TEPCO documents have been saying "non detected" on I-131 for months. That doesn't mean they are being honest. I am curious what his take is on it but didn't see a link and didn't recognize the name
    by lillymunster 11/2/2011 11:01:45 PM

  • @ all - the reference to tiny fuel pellets could it be "nuclear fuel fleas"? I heard this term used recently to describe tiny bits of fuel pellet that come apart as part of the meltdown process. The mention talked of them being able to get into steam or explosion matter. I think this was in an article about plutonium and how it could have been carried away from the plant

  • @lillymunster www.nytimes.com
    by Edano 11/2/2011 11:07:43 PM

  • @lillymunster, he's the author of the NY Times report or blog post Edano posts.
    by Ian 11/2/2011 11:08:37 PM

  • Ah - thanks!
    by lillymunster 11/2/2011 11:09:07 PM

  • the article is full of tiny, unknown details.
    by Edano 11/2/2011 11:11:07 PM

  • @Elaine, do you remember what document TEPCO puts out periodically with reactor radiation isotope readings? I thought there was one that had isotope types and how much? They do sea readings, monitoring stations around the plant and I thought they put out one testing the water in the SFP?
    by lillymunster 11/2/2011 11:13:03 PM

  • The NYT and this NHK one both hint at fuel outside of containment, the NHK one being a bit harder to interpret his exact intent due to lots of vague terminology. www3.nhk.or.jp
    by lillymunster 11/2/2011 11:14:49 PM

  • @lillymunster I will have a look
    by elainekirk 11/2/2011 11:18:24 PM

  • So TEPCO is running out of cash and cutting corners to try to pay compensation. They admit this fission issue and their stock price tanks. There is i-131 in the rice and now all these little hints of info like that NYT article has.

    They are running out of cash, it sounds like there is more going on than admitted and now hints of fuel out of containment, iodine being produced in fuel pools etc.
    by lillymunster 11/2/2011 11:18:34 PM

  • @lillymunster maybe as in march when the gocv wouldnt let them leave the gov are still refusing. Once somebody else gets into the plant even in an advisory capacity whoever or whichever body put them there is legally adopting a responsibility and therefore tepco could say 'that situation arose after following the advice/orders of x' and bingo tepco's dream of a get out of jail free card becomes a reality
    by elainekirk 11/2/2011 11:25:27 PM

  • Tepco have to tread carefully though, they cannot reveal the full extent of the situation whilst still having overall control of the plant otherwise they have responsibility so they have to turn public on government to force the hand of government but they can only do it by vague 'maybe's' and 'possibles'
    by elainekirk 11/2/2011 11:27:12 PM

  • Hmm TEPCO's PR guy really does dance around the issue:

    “There is a possibility that certain conditions came together temporarily that were conducive to re-criticality,” and that the measurements indicated a burst that occurred at a slightly higher rate than prior cases. “It’s not that we’ve had zero fission until now,” Mr. Matsumoto said. “But at this point, we do not think there is a large-scale and self-sustained re-criticality.”
    by lillymunster 11/2/2011 11:37:45 PM

  • so far as to "the situation is under control".
    by Edano 11/2/2011 11:42:49 PM

  • If you look at these examples of ground motion acceleration spectra from the base mats at Fukushima Dai-ichi Units 2, 3 and 4 taken from here www.kantei.go.jp , the recorded ground motion acceleration exceeded the anticipated ground motion acceleration most near 0.25 Hz, that is the resonance frequency of the fuel bundles. i1214.photobucket.com

    by Peter via I1214.photobucket 11/2/2011 11:43:03 PM

  • @Peter but .25 hz means one swing per 4 seconds, that is too slow to break, isn't it ?
    by Edano 11/2/2011 11:45:54 PM

  • not enough energy i mean.

  • Even MORE hot spots in Setagaya High radiation dose in Setagaya, Tokyo 15 new locations
    NTV (NNN) , March 11 (Thursday) at 7:00, 36 minutes delivery
     Problem is found from the site of the super-radioactive radium in Setagaya, Tokyo, found 15 new locations where the high radiation dose.  Two days and the ministry, was removed by digging the soil around the bottle and was buried in the ground, where the radiation dose was decreased to 25 micro bottle buried Sievert per hour. Is not in a bottle containing a mass of brown, the ministry has concluded that this substance radium radiation source.  Meanwhile, in addition to this location, was detected high radiation doses of 12 micro sievert per hour at 15 locations inside and outside the new premises. For these locations, the ministry sequentially to identify the radiation source dig the soil, with plans to remove the work is expected to be prolonged. [Articles] on the ground "radiation source" high-dose bottle collection Setagaya Setagaya followed by high dose of the reagent bottle dig working with high radiation doses, Setagaya, reagent bottles in the ground with high radiation doses, Setagaya, or radium-226 in Setagaya, Tokyo Drilling begins at the high dose area headlines.yahoo.co.jp
