  • On the Berkely Nuclear Site on the forum of Radiological
    and Water Monitoring in the Is planting a veggie garden in
    Ca. this year idiotic;

    Tim a member of the Brawm team made this comment.

    As for the possibility of increased levels of fallout, while I can’t predict the future, we’re pretty sure that there won’t be any further releases seen here in the US. The cores have been melting down for quite some time now (which is why they had the releases in the first place months ago). We will continue to monitor, but in the meantime I will continue to drink milk and eat tomatoes from the plant sitting outside my front door.

    This is an interesting observation. Does it mean that the
    corium already hit ground water and the explosions we
    observed were from the breaching of the containment?
    Thus the fears we have of a major China Syndrome are
    overblown
    Be interesting to have some feedback on this.
    If this is so then what we are going to see is more radioactive venting of steam and smoke but no more major explosions. The damage has been done?

  • @bojack54 - if you're around compare the 7 May big steam event with this chart of #3 temperatures www.tepco.co.jp

  • @Meretisa hi! hope you find the house of your dreams soon. re 3- I don't think there's major change. 4 looks as if it's collapsing more, but I'm prbably imagining it.
    by UKVal 5/22/2011 11:09:06 PM

  • Now if the vessel, suppression pool etc are all a close system, the explosion from the hydrogen buildup in the top of the building shouldn't have caused this to happen should it? This must have been something within the closed system and the vessel itself.
    by Rexz 5/22/2011 11:09:08 PM

  • @Sam, the fukushima reactor and spent fuel pool situation is still not in control totally, althought we've not seen explosions or huge releases of radioactivity does not mean there could be some releases and even yet an explosion (not expecting this tho).... keep posted to your local authorities and even this room for any releases of information

  • @all- have to go again. be back in a few hours
    by Meretisa 5/22/2011 11:10:35 PM

  • @Rexz If that tank is up at #5, 5 didn't have a hydrogen explosion. I think all that crazy twisting was done by the tsunami.

  • @Nancy Did you copy the pdf link ?
    by Reed 5/22/2011 11:12:07 PM

  • @Rexz pretty sure the isunami did this , there is a pic with the water coming in and going out then the tank, looks like this.... don't read japaese.. why do you think its water for 5 & 6 pools??? not saying your incorrect... just wanted to further look at

  • The last news from Fukushima inside Le Monde was last friday. Sorry it is google translate and only for sibscribers: Shy transparency about the consequences of the accident in Fukushima
    Something has changed in the information given to the Japanese on the nuclear crisis Fukushima. After two months ago to minimize the dangers to evade questions on the actual severity of the accident after the earthquake and tsunami of March 11 in four of six reactors at the plant, the Government, the Electricity Company of Tokyo (TEPCO), but also researchers previously stakeholders of the powerful nuclear lobby Japanese are beginning to show a little more transparency.

    Proof of this evolution, sensitive but timid, the government spokesman Yukio Edano pledged to do "everything possible to ensure transparency of information" during the visit from May 24 to June 2 of a team investigators of the International Atomic Energy Agency (IAEA). A confession that speaks to the policy followed so far.

    Similarly, the documents released May 16 by Tepco reflect the chaos at the station immediately after the earthquake of magnitude 9 that struck the Tohoku region, northeastern Japan. It appears from these report that, contrary to what the company and most experts "official" listed by the major Japanese media, the nuclear incident began before the arrival of the tsunami, evidence that the installation, yet built to standards considered the strictest in the world, has withstood the bad earthquake. The tsunami has only aggravated the situation. Similarly, ads Tepco that the reactor vessels were intact and the fuel had partially melted, were erroneous and especially so far from a reality that confirms the continuing danger of a situation even more precarious than the region remains subject to violent aftershocks of magnitudes such as 5.8 and 4.6, which hit eastern Japan Friday, May 20 The new data also jeopardizes the commitment of TEPCO, taken April 17 and reiterated on May 17, to regain control of the facility within six to nine months.

    But what most worries the Japanese today is information on the levels of contamination. The Ministry of Science maintains measurements in all prefectures.

    Several researchers, like Professor Kunihiko Takeda, an expert in uranium enrichment, challenge how they are done. It regrets in particular that they are made to 18 m high. In his view, it is better to take measurements at ground level, to determine the actual exposure of the population. But at this level they should be higher.

  • @LM it's certainly dancing around consistently - as if someone's on top of it & swinging around.No wind noise & little wind at the plant too. Strange...
    by UKVal 5/22/2011 11:12:28 PM

  • @Rexz, implosion of the surge tank could be caused by rapid cooling of the tank if its content were hot
    by WolfDK 5/22/2011 11:12:43 PM

  • Ok, my bad.... Looked interesting thats all :P
    by Rexz 5/22/2011 11:14:24 PM

  • @UKVal It is weird. I don't think I've ever seen the bobbing thing outside of them zooming or with major gusts of wind. (shrug)
    by LM 5/22/2011 11:14:57 PM

  • @WolfDK i have limited pc now, but pretty sure there is a sequence of water surrounding it and then leaving... i think the wave action twized it, but you may be right also..
    by fitter 5/22/2011 11:15:16 PM

  • @Rexz indeed, and i am only speculating
    by WolfDK 5/22/2011 11:15:28 PM

  • Try the following experiment, take a coke bottle fill it half with hot water, then dip it quickly into your kitchen sink filled with cold water
    by WolfDK 5/22/2011 11:16:49 PM

  • @UKVal @LM Almost looks lke we'e watching it from a boat, bobbing on the water.
    by NervousinNJ 5/22/2011 11:17:44 PM

  • Remember to put the cap back on before submerging ;)
    by WolfDK 5/22/2011 11:17:49 PM

  • @Rexz it is interesting, just wonder were to look about the info on 5&6 connection.. have been looking at abiut 100 drawings (that i did not print correctly and cut of info boxes) they are not japan, but if 50% is correct... the reactor systems are much more complex than anyone on the internet is addressing....
    by fitter 5/22/2011 11:18:18 PM

  • floating tripod? lol
    by NervousinNJ 5/22/2011 11:18:32 PM

  • @Rexz Don't tanks deform like that during a flood when they're empty?
    If so, the question is: why was the tank empty?
    by Reed 5/22/2011 11:18:48 PM

  • @NervousinNJ It does doesn't it!
    by LM 5/22/2011 11:20:01 PM

  • I would only think a tank would deform like that due to a change in pressure? Yes temperature change would cause it too, but that would be a pressure change of the liquid cooling/heating rapidly? Would this not have an effect on the sup
    pression pool too?
    by Rexz 5/22/2011 11:20:20 PM

  • @Reed dont think outside water pressure caused it, remember its much harder to deform a tank from the outside than from the inside, and its designed to be filled with water i guess..
    by WolfDK 5/22/2011 11:21:17 PM

  • Imagine a arc in an cathedral, apply pressure from the outside of the arc and it will support a huge load, aplly pressure from the inside and it will crumble with little force
    by WolfDK 5/22/2011 11:24:15 PM

  • @WolfDK I've seen pictures of empty tanks being crushed like that during floods. How do you explain the picture ?
    by Reed 5/22/2011 11:26:36 PM

  • @Rexz not saying all or none of the senerios happened... but tanks are not designed to keep tidial/wave action out.. they the design factors would be concentrated on holding water in and its forces... also have to look at if it had a vent... punp out a 18 wheeler and don't open vent the tank will look the same... seen it happen
    by fitter 5/22/2011 11:27:06 PM

  • @Rexz it would if the valves were open, when you lower the pressure you also lower the boiling point of water, and thereby its cooling capability
    by WolfDK 5/22/2011 11:27:33 PM

  • @Reed temp difference, filled with hot air, surounded by cold water
    by WolfDK 5/22/2011 11:28:10 PM

  • Correction: suddenly surrounded by cold water
    by WolfDK 5/22/2011 11:29:16 PM

  • @WolfDK why do you think the tank had a temp other than atmosperic temp???
    by fitter 5/22/2011 11:29:38 PM

  • @fitter I am guessing as to what caused the implosion/deformation of the tank, but it would make sense after a reactor scram wouldnt it ?
    by WolfDK 5/22/2011 11:32:01 PM

  • @rexz start at the beginging.. first is it fresh water make-up or sea water cooling, or part of a closed system on the fresh water side do you know any of these????
    by fitter 5/22/2011 11:32:34 PM

  • back and forth.. one thought.. most all tanks. fuel , water etc. have vents..
    by dean 5/22/2011 11:33:13 PM

  • @WolfDK it looks like the waves twized... like when standing on in the wave action on the beach and a strong current pulls at your feet
    by fitter 5/22/2011 11:33:53 PM

  • @WolfDK It's not a good image, but these storage tanks, when empty, will fold up like crushed cans during a flood... [IMG]http://www.beaumontenterprise.com/mediaManager/?controllerName=image&action=get&id=399494&width=628&height=471[/IMG]
    by Reed 5/22/2011 11:34:44 PM

  • @dean correct.... except if its "hot" which i don't think it would be, thats why i say it looks twisted
