Title: Temperature at No.2 reactor remains high
Source: NHK
Date: Monday, February 06, 2012 20:48 +0900 (JST)

Attempts to cool the temperature in the No. 2 reactor of the disabled Fukushima Daiichi nuclear power plant have only partially succeeded despite the injection of more cooling water. [...] 

TEPCO says the rise in temperatures indicate that the flow of water in the reactor may have changed direction after plumbing work, and is no longer able to properly cool down the melted down nuclear fuel.

However, the utility says radioactive xenon has not been detected in gases around the reactor, and that nuclear criticality is not taking place. [...]

Meanwhile, the Chairman of the Nuclear Safety Commission, Haruki Madarame, says that a recurrence of nuclear criticality is unlikely. [...]

    Hey, Taco, good to see you active. How bout this mess? So the water flow changed direction after plumbing work? Jeez, who did that work?

    • I heard a rumor (or was it a fairy tail) that the doc that says smilin will protect everyone from radiation did a surgery on this reactor core through the endoscope hole.

      He plugged the bent pipes n tubes n things that caused this reactor wessel to stop smilin.

      He then cut the spermin nuke production tubes, so it would quit producin nuke babes out of the bent up tubes n things. Then he welded it’s crack shut with a special smilin weld machine, sealin in the whole deal.

      Now the reactor is smilin agin, and no mo baby nuke thingies will be comin out.

      The side effect of the drugs they are givin after the surgery on this reactor is that it has a slightly elevated temperature..

      This is how the temperature is rising, but no more radiation is coming out, or so I have heard.

    BEG TO DIFFER! #3 is NOT a reactor… it’s a 4-R Radioactive-Reactor-Reduced-to-RUBBLE!

    So, it’s #3 rubble pile, and corium vent apparatus!

      • In regards to reactor 3 the containment dome is leaking. Thus there is a form of containment that needs only partial mentioning. ;) It is still a reactor in regards to a reaction taking place.

        Hence nuclear reaction.

        The Reactor 3 primary containment is experiencing hyper venting today. Which indicates the coolant is above boiling point. As always fission is responsible… This is not to be confused by emissions coming from the fuel pool. Which would come from the South end of the facility. Thus the Core emissions are likely the culprit.

      Agreed, how can you call a pile of sticks a reactor?

    It’s not a reactor, it has crossed over to the other side and become a mini fuel pool.
    It is no longer, it has gone to a mini fuel pool heaven now..,
    Where it can cool off in pristine waters and so forth.

    They keep putting out press releases on 2 today, so you can be assured that the place to pay attention to is not #2.

    “Dearly Beloved, we are gathered here today to lay to rest Fuku #3, or Fukusan as it was fondly called. He has labored long in the nuclear vineyards and suffered his death at the hands of his short-sighted creators… who didn’t really believe those old standing stones that told about tsunamis and who thought ground level was a swell place for backup generators and many stories high a great place for hypertoxic fuel pools…

    Well, if it’s the usual Press-tidigitation of TEPCO’s, bad news of 2, 3, and 4, along with worries about 5 and 6, must mean that unit 1 must be the really bad story. And it’s hidden from view….

    Which leads me to the burning question: where is the fuel gone???


    Report Comment

    • Burning questions are not allowed.

      We are in cold shutdown.

      Only liquid nitrogen cooled questions are allowed, and then only if you have an extra couple of hundred gallons of liquid nitrogen in case of about 30 uncontrolled ‘leaks’.

    Now I lay me down to sleep
    While gamma rays nibble at my feet
    Our future is now foretold
    By radiation levels 100 fold
    In lead-lined beds we will rest
    After crushing our bones for the Strontium test
    So no more worrying about a thing
    Now is time for the *fat lady to sing

    Discussing Nuclear news today with friends, someone pointed out that we have evolved to *absorb high levels of contaminants. Even with an increase in diseases & cancer many people have a *new form of healthy.

    With news of one friend with esophageal cancer & one passed away this week I am a little overwhelmed.

    And yet in my heart Hope exists. But right now just not sure why.

      Great prose Maiden
      I think your friend is right about the development of resistance… it only makes sense scientifically.

      It wont be pleasant, evolution has always been about Out with the old and In with the new.

      The ability of the human body to suffer and deal with radiation and toxins is amazing, though certainly has limits. If we had a human being with no ability to suffer any radiation or toxins, can you imagine how much code would have to be written to give that being the ability to do so?

      How would one write the code? It would take years just to research the science. Instructions would have to be written, to integrate the new ability, at myriad levels, from each individual type of cell in the body, each tissue, each organ, not to mention the brain, and on and on. It’s only recently been discovered that genes function three-dimensionally, not just linearly, making it ever more complicated than previously understood.

      How does your body deal with solvent contaminant? It handles it, moves it around, stores it, sends it out in urine, fecal material, breath, sweat, hair. None of that is not accident, it’s according to genetic instructions. It’s according to code.

      It takes scientific knowledge, chemical engineering skill, foresight, supreme programming ability, knowledge of the environment, knowledge of the whole code at once and all its possible variations.

      And most people, especially most educated people, think this happened by chance? They ascribe this to an unthinking, uncognizant, random selecting, ‘thing’, the environment; which they ascribe intelligence and decision-making ability, among all the other necessary things.

      As someone recently wrote, who made this observation, and pointed it out to me, that is idolatry. The people have made them a god, to replace the obvious God.

  • If they can’t cool molten cores properly, of course it will lead to re-criticality. All of us here who have made ourselves reasonably knowledgeable on nuclear power know that even spent fuel must be cooled down for several years or it too will start the fission process. TEPCO is known for not telling the truth and revealing news after the fact. Is it still a nuclear reactor? Just like a car that has hit a brick wall at 100 mph is still a car. Its a wrecked car and can’t function as it was designed, but still a car. They are still nuclear power plants but they can’t generate power and they are not containing the nuclear poisons. You could call them nuclear poison factories and you could call that wrecked car $50 worth of scrap iron. I think Shakespeare had the last word on whats in a name. “A rose by any other name would smell as sweet” And a wrecked nuclear reactor spewing radiation into the air and ocean is still a major health hazard even if you say its in cold shut down

  • So rising temperatures are NOT associated with criticality or fission… Hmmmmmm, I am going to have to give that one some thought… How does that work exactly in the melted down, melted through nuclear reactor world?

    They are supposedly POURING cold water on a non existent reactor core that is in ‘cold shutdown’, but the temperature is RISING.

    It must be those darn Tasmanian Devils coming up from down below, to dance on top of the cool down formerly melted corium dance floor then..

    They have some really hot breath and the friction from their dancing shoes is building up heat inside the building..

    Darn those Tasmanian Devils… and those pesky wabbits are right behind em.. causing trouble.

    yea, I can buy that.. if you pay me 2 Million Dollars in GOLD, I will buy that explanation.
