    • norbu norbu

      good morning do you think #3 #4 are falling in on themselves? they look odd.Has the fuel melted through the cement yet?

    • SteveMT

      As the saying goes: Where there is [radioactive] smoke, there is ….

  • charlie3

    ok, so what is happening now to cause a still greater level of radiation inside the drywell of #1?

  • fromtokyo

    today people have measured quite higher air radiation in tokyo area. about 0,13~0,2uSv (it was about 0,11 the last days)

  • markww markww

    Radiation is going to go up and up since its out of the containment and no water it is just giving off all its deadly glory. Its time to add 7 anti nuclear elements to first top level and then concrete the whole mess in all the reactors

  • AkDave AkDave

    Just keeps getting better every day! Stock up on food now.

  • itstomd

    in some respects its like fire. i think its eating thru, falling in the drywell and creating fission because its “dripping” (this stuff is placed in exact distance in the racks with water!!, thats now gone). when this stuff is next to each other so close it burns up then cools alittle, shifting makes it get worse. We worry that it does not get in a way that it goes boom. one “exploding” atom, break more atoms, and more atom, till boom.

    I wonder how all this radiation effects the entire structure, my thoughts are that the atoms in the building are getting ionized and causing it to get weak.

    The gamma ray pictures look really bad. You can see that around the edges of doors and cracks lotta gamma, so the atoms on the inside of the matter ( walls, and such) must be getting destroyed something else.

    • lokay5

      Boom goes the dynamite

    • The structure is inquiring extreme humidity, It is much like a steam room in the interior. This will effect electrical lines, remote sensory, and even create rust in some cases. The atoms attach themselves, to 99% of the surfaces they encounter.

      That being said, the main concern is the 84 day period of accumulation that has occurred.

      You are very correct in respects to the fuels integrity within the now damaged fuel pool. The fuel rod assemblies, must be held to enormous amounts of guidelines to prevent hyper hyper-criticality. (explosion).
      This is why tepco has implemented the addition of boron in respect to cooling operations. Limiting atomic reaction’s within the spent fuel pool.

      This is a temporary solution to an otherwise greater problem. The critical fuel is more than likely able to breach the base of the sfp; before any course of action is fathomable.

      Tic tock.

        @Tacomagroove

        I’m having some difficulty understanding your post.

        “The structure is inquiring extreme humidity” – did you mean to say ‘acquiring’?

        “This will effect electrical lines” – did you mean to say ‘affect’?

        “the main concern is the 84 day period of accumulation that has occurred.” – accumulation of what?

        “The fuel rod assemblies, must be held to enormous amounts of guidelines” – ???

        “to prevent hyper hyper-criticality.” – link please, to any scientific reference which describes a ‘hyper hyper criticality”.

        “The critical fuel is more than likely able to breach the base of the sfp;” – are you referring to the SFP at R4? If so has it gone critical? Link please!

        “before any course of action is fathomable.” – does this imply that nobody will understand the nature of the current activity until after the event?

        I’d normally be inclined to smile and move on, but this is a serious topic, with lots of nervous readers. Not the best place for a bright adolescent posing as an adult expert on nuclear fission (which you often refer to as fusion btw). You already have a significant number of enthusiastic followers who lack the necessary skills to differentiate between science and psuedo science, and my concern is that you will eventually panic one or more of them into taking inappropriate action. We all see the serious nature of the events taking place in Japan, quoting Arnie then adding your own apocalyptic spin does no good for anyone, it just spreads more fear in the wrong places, and for the wrong reasons. Anyway it’s already apocalyptic enough for everybody.

        Btw I’m always interested to read a new theory, even from an adolescent, provided it’s postulated as such, and not smugly announced as ‘the truth’.

        I realise there might be some angry responses to this, please know that I act out of concern for the safety of others. Isn’t that why we are here in the first place?

        • “I’d normally be inclined to smile and move on”‘
          (no you wouldn’t)…,
          “but this is a serious topic”
          (this we both agree)…,
          “with lots of nervous readers”

          Yes; I told them all to read…
          Its safe to have a emergency kit too…
          Something I missed?

          We all see the serious nature of the events taking place in Japan, quoting Arnie then adding your own apocalyptic spin does no good for anyone, it just spreads more fear in the wrong places, and for the wrong reasons. Anyway it’s already apocalyptic enough for everybody.

          Look, You want an angry response, its a relative thing to want for someone that likes to bash someone, to prove their point, with out having common sense, to facilitate a simple opinion…

          I have no reason to actually, Be any more specific, in anything I write… Its all an opinion.
          In fact I have already claimed im no expert with any licenses or qualifications in nuclear physics.
          I am an event planner.
          Thats what I said…

          But here’s the situation…
          There are 4 nuclear reactors, in a very dangerous state, contaminating, national and international food chains daily… The situation is in fact very serious by all accounts…

          Its: “Super Chernobyl”
          Get that through your head…

          You don’t have to have a degree to understand that the “pick up sticks” are about to “drop the marbles”…

          Or tell me exactly what tepco is going to do to restore the reactors cooling systems and re contain the nuclear fuel that has breached its containment…

          Before the contamination say doubles, or triples…
          Do you know how long that will take…
          Do you have common sense?

          I think the people standing at the side lines, are the most likely people to get kicked during the game…

          ying, yang, whatever…
          Emmy.

          • The bottom line is, if you are taking no precaution, especially just limiting yourself to even just reading you are truly misinformed…in respects to the magnitude of the situation; bearing in mind its very real dire consequences it may in time bestow upon humanity…

            We as a collective conscious must prepare for the unquestionable events to come in the very near future….

            Physicists agree the situation and its repercussions can be unimaginable. unfathomable. Biblical. apocalyptic…

            I ain’t the one Coming to terms with those headlines…… bbc was.

            IM simply bringing it to the attention of others…

            Not me……

            “Look, You want an angry response”

            No I don’t, I said “I realise there might be some angry responses”.

            “Its: “Super Chernobyl”
            Get that through your head…”

            I agree. Most of my posts would confirm this. As for your disrespectful tone, that’s the anger I was expecting.

            “Before the contamination say doubles, or triples…
            Do you know how long that will take…
            Do you have common sense?”

            Nothing here that requires a nuclear explosion. And again with the disrespectful tone.

            “I think the people standing at the side lines, are the most likely people to get kicked during the game…”

            I take it from this that you see yourself as a ‘player’ in some kind of ‘game’?

            Like nearly everyone else I have no answers, only questions, conjecture, and a deep sense of sorrow. You appear to be enjoying yourself mightily, however.

            Steven,
            TacomaGroove blogs a lot on Godlikeproductions which is purported to be conducting research on individuals who blog on doomsday websites. This research is supposedly conducted by Tavistock and Stanford Research Institute who teach psy ops. There are also computer programs developed for the government which allow one person to have many names and keep a blog going. Arguing with anyone on this blog is likely to be counter productive.

          • Steven Steven

            Thank you anne, I wasn’t aware of that. I appreciate the ‘heads up’.

    How High Can It Go?

    I was off by about a factor of 10 in my comment on the previous thread. So I correct it here.

    At Chernobyl 30,000 Roentgens or 2,579 Sieverts per hour were detected in the early stages of the disaster.

    Like this we have an idea what might happen if R4 SFP blows.

  • nomade

    Just curious as I can’t see the JNN feed, just the tepco one. Is it showing exactly the same thing or something different?

  • fromtokyo

    is it still smoking?
    cannot judge it..smoke or pixel?

    • Whoopie Whoopie

      Not as bad as it was.

    • Heart of the Rose Heart of the Rose

      It’s smoke..steam..vapor.
      Pixel motion interpretation is best left to those that know what they are looking for.

      • Sickputer

        Well, we’ll get a better view at sunrise and not too long from now.

        Here’s a good site that tells us when Fukushima has daylight hours and how many hours:

        http://www.gaisma.com/en/location/fukushima.html

        Also at bottom of that page it reads your IP address and shows your distance from the plant (in Kilometers). Hope yours is a big number! *;-)

        Coming up soon is the longest day of the year…June 21 which is my dear departed mother’s birthday. Luv ya mom!

  • Heart of the Rose Heart of the Rose

    To imply that the interpretation is faulty here because we are Jesuits..is disinformation at it’s best.
    It is true however that the Jesuits will morph into any Christian organization that it feels is the most effective at the time.

  • nomade

    I can get the tepco video OK, it’s the other one that’s blocked in Europe.

    Just curious if smoke/steam events can be seen simultaneously on both feeds.

  • nomade

    It’s a great pity we only had one video of the big smoke the other day.

    When nothing is happening it’s hard to tell when the filming is taking place…

    I realize that there is supposed to be a 30second time lag but I took some stills the other day using a good old camera which showed the time on my computer clock. The time lapse wasn’t the same the next day… there was difference of 15 seconds.

    So either my computer clock is really inaccurate or their live feed isn’t a live feed.

  • SteveMT

    Live web cam: Imagine if there was a counter with the # of visitors/day and the # currently watching this live feed.

    Those data would us a good estimate of how well the message about this disaster is reaching the world.

    Just thinking out loud about something else that they do not want to tell us about.

  • bleep_hits_blades

    I am trying to find information re the spread of the Fukushima radiation into the Southern Hemisphere.

    Does anyone know where online to find that info? (ideally, imaging)

    Also what are your opinions re advisability of moving if possible and where would be best place on the planet to move to?

    • BreadAndButter BreadAndButter

      Bleep,
      I also made a research on the net – no ifo, I think, our friends in the south did not yet wake up. I would imagine (having no clue of weather patterns and nuke physics) that over a couple of years all the nasty particles will have settled more or less evenly over our lovely planet. Espeacially when there’s not one massive blast like Chernobyl, but a long term constant release as it seems to be right now.

    Heads up here about Rima Laibow, hubby Bert Stubblebine, and their Natural Solutions Foundation. Stubblebine was career military intelligence specializing in dis-info(!) Not a guy I would trust. Of course if pressed/confronted he probably claims to have ‘seen the error of his ways,’ etc.

    Check out article on him at above link.

    Agreed Codex is odious and execrable and should be opposed. But we all know or should by now that pied piper dis-info agents have to present a front that will suck all the kiddies in, the better to mess with their minds and also gather info on them.

    Just a heads up on the graphic for this thread.

    The data span appears to be for May 21 2011 through June 12 2011 (based on the date axis, graph bottom edge)

    The header text for the data says March 15 2011 to December 6 2011

    @bleep_hits_blades

    All I know is that they have been fighting against Codex and other damaging health proposals for YEARS. This is a time to get behind ANYONE who is trying to defeat the forces that are trying to ELIMINATE US.

    Can you provide us with the names of someone who you believe is doing a better job?

  • CleaN Nrgy

    I’m sure I can see a faint whisp of steam/smoke rising from R1 as well this morning. The only reason we can see steam above R4 for most of the time is that there is a tower (dark object) behind it. In all other Reactors, it is almost impossible to differentiate between steam and the sky due to the crappy streamed video quality and lighting.

  • Heart of the Rose Heart of the Rose

    They are all steaming including 1..
    These buildings are huge..no small wofting.

  • Heart of the Rose Heart of the Rose

    Why would they stop “steaming”?

    • Two things,

      1.The water is completely evaporated out. You would likely witness vapor in its replacement.

      2.The addition to fresh cooled water, would enable the temperature from rising beyond boiling point;(until the fuel heats it up again).

  • Heart of the Rose Heart of the Rose

    Nuclear chain reaction is self-perpetuating.

    • It depends on a number of things, closeness and shielding but there gave been numerous reports and guestaments that fission was taking place at different times !

  • Heart of the Rose Heart of the Rose

    Actually..I’m not studying it..It’s just a given….some folks need numbers.

    Yeah. 260sv/hr is nothing to sneeze at. I’ve been watching this chart for quite a while and it certainly tells a tale of something still very wrong in Unit 1.

    With the addition iodine still present there’s obviously some level of continued criticality.

    Here’s an interesting graph of current temperatures from Unit 3 – obviously something is still very wrong there as well.

  • Stephengn

    What is the reason for the ups and downs in this graph?

    Shouldn’t it remain constant?

  • blackmoon

    Here is more information concerning the apparent mutation of wild (and non-sheltered) animals:

    http://theextinctionprotocol.wordpress.com/?s=WILD+DOGS

    I pose this question; would we see mutations in the animal kingdom before sickness in humans?

    Wild animals fending for themselves would be exposed to more radiation than household or sheltered animals. Do you all think that these mutations, and the aggressive behavior they exhibit, could be caused by radiation? Or is this just a coincidence?

  • icone

    My understanding is that a critical or semi-critical corium blob would tend to sputter as parts become more or less critical and hot. As a crust forms on the corium, some heat and radioactivity is contained inside the blob. As the inside of the blob heats up, it becomes more molten, and the crust can break, leading to increases in temperature and radioactivity.

    The 2 scenarios are that the corium will cool down on its own, perhaps very slowly -or- that the criticality will continue and increase, eventually boring down into the watertable, etc. etc.

    The Unit 1 graph seems to show this sputtering, and that the level of radioactivity released is increasing. If the data is correct, I think it shows conclusively that #1 not only has ongoing criticality, but its getting worse.

    Perhaps one of the experts wants to weigh in, I’m no nuke engineer, just interested in whats going on.

    Can anyone help? I’m constructing a graphical timeline of the Unit 1 Drywell events, and would like to find more saved copies of the TEPCO graph from http://atmc.jp/plant/rad/?n=1
    I have Mar 17 to Apr 8, and May 18 onwards.
    Seems they never published any D/W readings from Apr 9th to May 17th, or am I missing some?

    Very importantly, did anyone save TEPCO’s graph between May 18 to 21? (Before it jumped up to 200 Sv/Hr)

    It’s looking like I can prove the bastards have been lying about Unit 1 criticality IN THE DRYWELL since April 9th. Just need to get a few details more solid.

    Please email to TerraHertz (at) everist.org

    MoonKai, that’s very bad news. 36 million people bad news. I don’t know what ‘milk and cheese’ is thinking; doesn’t sound like ‘safe’ to me.
