Tepco no longer monitoring thermometer — Temperature remains steady around 220°C — Will stop added water injections if gov’t says it’s reasonable

Title: TEPCO reports reactor thermometer problem to govt
Source: NHK
Date: Thursday, February 16, 2012 17:28 +0900 (JST)

[...] Tokyo Electric Power Company, or TEPCO, reported the analysis of the problem at the Number 2 reactor to the government’s nuclear safety agency on Thursday. [...] 

The utility said it’s highly unlikely that temperatures could rise so high unless at least 60 percent of the melted nuclear fuel in the reactor were concentrated near the thermometer. [...]

TEPCO says the thermometer will no longer be monitored. The firm says it will comprehensively examine data, including other thermometer readings and radiation levels in the reactor’s containment vessel, to determine whether a state of cold shutdown is achieved.

The utility plans to reduce water injections into the reactor to a level at which such injections were done before the thermometer readings began rising, if the nuclear safety agency says that doing so is reasonable.

    guharbage again from TEPCO. Yeah 220c sounds reasonable to me and definately in cold shutdown…lol

    "TEPCO says the thermometer will no longer be monitored."
    Translation: IT is so out of hand we are not going to tell anyone the truth, so badly we don't even want to know.

    The government needs to step in here (probably just as useless) and start telling TEPCO the score instead of TEPCO telling them the score with their continual lies.

    I bet if the entire place fell into the ocean TEPCO would declare the site clean.

    Didnt the government tell TEPCO to REPLACE the temperature gauge? Guess TEPCO told them…NO. So now you know who is in charge..its not the Japanese Government, or the Japanese people.

      Previous post of mine advising that Tepco were refusing to accept Govt rescue money without conditions i.e. without giving away operational control, source: Tokyo Times. Between the lines, boardroom dispute over this, but subsequently rescue package agreed so who TF knows what is really happening… this tends to suggest agreement with your point; and the background plot appears to be a totally non existent (sarc) threat by Tepco that the power supply to Tokyo was at risk. Of course, this has to be entirely made up (sarc).

      Reminds me of some of those stupid films where arch criminal masterminds demand zillions of gold bars in order not to blow up London/ Paris/ New York/ Tokyo (sorry, erase last one was a mistake)

    Ah! Now I understand. If the reading is rising, the gauge is faulty. If the reading is falling, the gauge is ok again. If the reading is steady, we can ignore it. Wish they had taught me this kind of science in school.

    It's come to this. Thank heavens, admin, and the rest of us for all the laughs and to Tepco and Hon Japanese Gov for humour generating material.

    We're all going to die, but at least the enenewsers will die laughing.

    Sorry this is not meant to offend but my refuge of choice today is black humour. Best wishes all, and admin, from

    From the last page of the 775 page thread at the Physics Forums.

    A contributor says…..
    "I feel really amazed that a cheap two-wire thermocouple configuration was used and no four-wire-one with return wires.

    With a four-wire thermocouple it would have been possible to narrow down the cause of the problem without having physical access. Possibilities include damage of the thermocouple element itself, wiring damage, shifting/decalibration etc."

      Thanks, Spectro. Since your post someone added this:

      "Tepco is studying new thermometers for unit 2. Already 8 out of 41 or 20% of unit 2's thermometers are broken. As more might break down in the future, Tepco is studying how to install new thermometers. As one cannot easily approach the reactor, the study will take from one to two years."

      It's all so Monty Python-ish.

      To which the proper reply is:
      "Of course they used 2 wire thermocouples, there was 0 chance of a meltdown, so we didn't need to waste money on reliable thermocouples…"

      Of course, if they really wanted to save money, they should have just thrown away the blueprints to the reactors and not built them.

  • they have a broken thermometer which they conclude is right "only when 60% of fuel" is next to it… some 100 tons…
    what a bs

    additionally : when they put in more water the temperature of the "working meters" did not change, so the question arises if cooling is needed anyway…
    and after all that "tepco does it alone due to legislation" they now search approval by government

      I agree catweazel..You could be forgiven for thinking …."Nothing works!" :-)
      What we are dealing with here is "'a soap bubble that lasts a long time only in a quiet medium'. "

    TEPCO – "We can no longer lie about that thermometer, so we will now ignore it." Unbelievable.

    Did he go down that endoscope hole?

    I bet that pesky wabbit is the one chewing on the wire and causing the temperature swings..

    Dang those pesky wabbits..

      Tepcos' technique
      for lies not unique:
      think Elmer Fudd and

      with Bugs on the run;
      down comes the scenery
      while Bugs eats a carrot.
      Scattershot lying -

      So Monty Python and Looney Tunes,
      Bugs Bunny/Roadrunner Tepco goons

      It was said

      and that's the damnation,
      for Tepco and J-gov -
      they're killing children,
      trying to keep it hid,
      killing the helpless,
      crushed by the fist,
      inside a mailed glove of nuclear mist.

    doesn't matter
    what the temp is anyway because there's zip they can do about it. In fact, best not know. In fact……. they should organise to have all thermocouples broken, that will shut people up!

    Water injections will cease is the government finds it reasonable….
    Since when did TEPCO take orders from the government?
    TEPCO will tell the government ..when they are done with water injections. (or they will decide together…camaraderie among beggars and theives)
    They ought to forget the temperature ..the patient is "code blue".

    Yes,…and,…the 'patient has left the building'!

    Yep ..the patient left the ward unattended..and died in the parking lot.
    The body is radioactive and no one wants to touch it…. the corpse is starting to rot.

    So we're telling the family that the patient IS NOT DEAD,….until 'we' figure out what the hell to say killed 'him/her'. Got it???? Got it!!!
