Title: Temperature remains high at damaged reactor

Date: Tuesday, February 07, 2012 13:05 +0900 (JST)

An unknown rise in temperature at one of the reactors at the damaged Fukushima nuclear plant is troubling its operator. Tokyo Electric says the temperature hasn’t gone down even after it increased the volume of cooling water on Tuesday.

One of the thermometers at the bottom of reactor No. 2 at the Fukushima Daiichi plant gradually rose to about 70 degrees Celsius since January 27th. It had stayed around 45 degrees before.

In an effort to lower the temperature, the operator increased the amount of water sprayed on the nuclear fuel by 3 tons to 13.5 tons per hour Tuesday morning.

But Tokyo Electric said readings were down only about 3 degrees after some 5 hours of operation, hardly showing signs of improvement. [...]

    “Sprayed on”. If anything says how little control they have. Another phrase that should never appear in the same line as “nuclear fuel.”

    Ok, somethings I would love to have feed back on this.
    They are measuring 73 million bq/hr emissions of CESIUM.
    Cesium act like sodium or potassium, throw it in water it explodes!
    Instantly forms cesium hydroxide (like lye NaOH)
    Sure, it’s gaseous after a bomb or meltdown….and neither of those involve much water do they?
    Iodine would make perfect sense, and that’s scary, think somebody else should have picked it up……

    Ok, what’s the nitrogen injection like in terms of volumn of RPV.

    Let’s say we had cesium forming in the system….it goes into solution as a hydroxide ph would be close to 14. As if forms it kicks out H2….they have reported before.

    Ok, take it from there

      plus hydrazine, from the Tepco report..

      so.. all the normal crap from nuke reaction, plus nitrogen, plus water, plus air, plus sodium(sea water), plus hydrazine..
      sounds like a crazy chemical cocktail, with unknown potentials for reactions..it is like watching a mad scientist.. pinky and the brain…

      ..no idea why the temp is going up, maybe we will read those manuals after all, oh well.. bunch o homers..
      the whole dang industry!

        hydrozine is N2H4 usually an O2 scavenger,anti corrosive
        too late for that
        stuff been soaked in salt water, ionics take over acting as much like a battery as anything as it dissolves metals

          thank you, I wondered if all the chemicals are having impacts that are not considered.. maybe pipes burst due to the hydrozine? they have been adding since at least may.. and don’t forget the boric acid too..

        “Hydrazine” caught my eye. One more thing to pay attention to at the site. From Wiki:

        It is a colorless flammable liquid with an ammonia-like odor….

        Hydrazine is highly toxic and dangerously unstable, especially in the anhydrous form. According to the U.S. Environmental Protection Agency:

        Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, coma in humans. Acute exposure can also damage the liver, kidneys, and central nervous system. The liquid is corrosive and may produce dermatitis from skin contact in humans and animals. Effects to the lungs, liver, spleen, and thyroid have been reported in animals chronically exposed to hydrazine via inhalation. Increased incidences of lung, nasal cavity, and liver tumors have been observed in rodents exposed to hydrazine.

      Ocean. They are just pumping in water..and more water. Where it goes nobody knows…Ocean is as good a guess as any. OR into the ground water. Is anyone checking radiation levels in ground water around the Fukushima I plant? Anyone see any increase in water flow to the lagoon from Reactors 1-6?–and on into the ocean?

      In one diagram, it showed co-jointed corium pools from all the four reactors. Guess if situation is of merged radioactive materials-water could be flowing into area. If so, could there be a build up of steam/gas pressure if it can’t vent or drain? Or does it just flow int the water table? Just a layman on this, but physics is physics.

    “may, might and maybe,
    we don’t really know
    could be or sorta”
    (awkwardly bow)
    ow -that hurt my back –
    gotta practise my swing
    I’m due for eighteen
    away from this thing -
    “so please go away
    and ask questions never.”
    why do I feel
    like I have a fever?
    “The next press release
    will tell more – I think.”
    I’m feeling nauseous,
    where’s the nearest sink?
    “As Americans say -
    ‘leave it to Beaver’
    smile and be confident
    we’re like Ward and June Cleaver!
    kindly and knowing
    for our precious kids!”
    There’s gonna be trouble if
    they find what we did.
    “One more thing, maybe two,
    or should that be three – ”
    oh hell make it four,
    between me and the door
    it makes no difference
    at all anymore -
    “The next press release
    will be from Hosono,
    dressed in his special
    Seppuku kimono!”
    Oh no what did I say?
    My brains starting to rot!
    I shouldn’t have come to
    this damn plant so hot!

    So concludes another reassuring conference from Tepco.

      95 degrees per one report supposedly from TEPCO employee –surprised no one had announced the increase to that level. Are the workers still there–are they to be evacuated? Anyone concerned about the local residents who “came back” because the government said so? Or those within 80 KM of Fukushima? Would it be smart to remove the children to a safer area until the mess stablizes.

      Since no one knows what is going to occur. Please Please PLEASE have them err on the side of over-reaction..and protect the little ones.

        Agreed jec….seems obvious….
        300 klms to be on the safe side, but more importantly, issue detection devices to be assigned to the most responsible nominated person in say a group of each 10 families also. air filters, electrostatic and HEPA….respirators and so on…
        The idea that even such measures cannot be employed reeks.
        detection, detection, detection, detection. and more detection, not less.
