Nikkei report published at 9:55pm ET tonight, translated by Babelfish:

Fukushima nuclear plant 2 the pressure container of the machine, it rises to 78.3 degrees

Tokyo Electric Power announced that 12th morning, Fukushima 1st nuclear power plant 2 temperature of pressure container bottom of the machine same day at 10 o’clock in the morning rose in Celsius 78.3 degree. According to Tokyo Electric Power Company, value of this temperature in the December last year later cool temperature stopped state is declared, reaches the highest value.

You call 2 the thermometer of remainder that it is transitive at approximately 35 degrees.

2 temperature of machine pressure container bottom rose entering February, but once it had decreased to approximately 65 degrees by increasing the pouring water quantity for cooling. But, 11th in the afternoon again in Celsius 74.9 degree rise. In the 11th night the pouring water quantity per hour was made 1 ton increasing and the same 14.6 tons. As for Tokyo Electric Power Company, because you cannot see the effect of cooling, you say that modification of the pouring water quantity is examined.

EX-SKF has the press conference details:

[…] TEPCO do not give morning presser on weekends any more, but today is the exception due to the concern over the Reactor 2 RPV. Matsumoto is doing the press conference, instead of the usual junior manager of PR department.

Q: What happens if the temperature here exceeds 80 degrees Celsius?
A: Further increase of water to be injected into the RPV. But the cold shutdown state should take other parameters of the reactor into consideration.

Q: Possible causes?
A: Unstable cooling at the location. Some movement inside RPV of melted fuel, possibly, disturbing the flow of water. We don’t think it’s likely because we haven’t been working near the reactor. Instrument failure is another possibility. […]

    We’ve been told the device margin of error is +/- 20 degrees, but they report values to a tenth of a degree to give the illusion of precision?

  • Laterlukemayb Laterlukemayb

    Not trying to change the subject as the most IMPORTANT THING here as that they keep molten mess cool, but……where are they planning on putting the millions of gallons of radioactive sea water when they eventually get that MOLTEN MESS to room temperature???

    Just wondering is all.

  • vivvi

    maybe all this spin is heating it up. if they don’t stop it will blow apart with centrifugal bullshine force.

  • StillJill StillJill

    Yeah, and ask that Tony Dude from BP,….”It’s a big ocean”, right? NO!

  • jec jec

    It seems like Reactor 2 will repeat last weeks smoke event..before it cooled down. Wonder if this is going to be an ongoing cycle? Sure hope the runoff, full of radiation, is captured and not going into the oceans. Sad, think it is a direct transfer. If anyother countries are worried, its time to try and assist in the decontamination if nothing else. Once the oceans are polluted with radiation, there is no way to fix or correct the damage. Is anyone listening??

    • stopnp stopnp

      All the water they injected into and onto these reactors has made it’s way into the ocean or the groundwater. There are some on site tanks. Those were full a long time ago. This site has those reports. They continue to dump hazardous liquid waste in the ocean. It’s not going to stop either

  • StillJill StillJill

    No deaf ears here my friend!

    • jec jec

      @StillJill yes, great hearing –just wish the governments would wake up before its too late. Alternatively, does lack of activity mean it IS TOO LATE? Thanks for ENENEWS people, such as yourself, keeping up the pressures. Frankly getting pretty depressed on the situation.

      The fingers trying to hang on…are slowly slipping off the edge. Its a very long way down..

      • StillJill StillJill

        I know jec.

        Sometimes I think the Big Kahoona,…and I mean the BIG Kahoona, shields us some days,….from really ‘feeling’ this intensely.
        Then, as we’re able, we get shown some more.
        I’m reminded always of Corinthians 10:13, not to preach,….it’s the “God will make a way to escape, that ye may be able to bear it”, scripture.

        And secondly jec,….I’ve had to do a gratitude list most days just to stay afloat. But I realized that if I have sufficient for this day, a warm, safe place to sleep, food, and friends,…..I truly am BOTH wealthy and PRETTY PROTECTED by something! And,…we have LOVE, and each other. Even when we’re alone, we’re not. I know this to be true more than most as a near shut-in. We are not alone,….and you jec,….are under ‘Sure Wings’ my friend! 🙂

        Government has a new slogan for the seriously depressed.” You can’t say Fukushima without a smile”.

  • Laterlukemayb Laterlukemayb

    At the current rate of water flow how long will it take to cool the melted fuel to a safe temperature?

    Just wondering is all.

  • StillJill StillJill

    Haahahhaa, snort, Haahahhaa, snort, snort. Sorry Laterlukemayb,…I’m from Ohio too, so I almost hated to laugh with stopnp,….but I just couldn’t resist a good snort!

    TEPCO provided radiation map to U.S. before Japanese public

    TOKYO (Kyodo) — Tokyo Electric Power Co. provided a contamination survey map of its crippled Fukushima No. 1 nuclear plant to the U.S. nuclear regulator nearly a month before its official disclosure to the public in Japan in late April last year, company officials said….

    ….An official at TEPCO’s public relations department said the company had provided data on the radiation amount at the Fukushima No. 1 complex at press conferences even before the official disclosure of the map, adding the utility “received advice” from the NRC.

    As most of us here know, or at least suspect, these already ‘mortally wounded,’ tottering, collapsing structures are just going to keep on deteriorating, and we will have meltdowns in all of them. (Keeping in mind that the radio-nuclides are damaging not only to living creatures but also to metals, the structures themselves.)

    The infusion of radio-nuclides into the biosphere is going to be humongous (already is massive).

    All TPTB can do is lie about it, trying to keep the truth from the public – of the world – as long as they can.

    I keep wondering what the reaction of the masses will be when the light finally dawns.

    Elites are going to want to muddy the waters, throw a lot of distracting manufactured crises at us, like this Iran thing. And the impending financial collapse, inflationary depression.

    Great guys, these ruling elites.

    Forgive my ignorance, but to the point of the fuel moving around in the RPV I thought most the fuel melted out of the RPV into the primary containment hence the whole china syndrome talk. Since they appear to be measuring the temp of the RPV, how accurate will the temperature be if most the fuel is down below? Do these temps even matter? Isn’t the fuel far from the temp sensor like in a completely different part of the reactor? lol Could anyone clear that up for me, please?

  • StillJill StillJill

    Bones, you’re being too logical like Spock! 🙂

    • Bones Bones

      Lol Good, so I’m not crazy. I was thinking I had amnesia or something. I think the sensor is malfunctioning unless the temps are extremely high at the bottom of the primary containment. This just feels like a misdirection.

      • StillJill StillJill

        You are not crazy Bones. I read it the same way you do.
        So,…if you’re crazy,…well, you’re not alone. 🙂

    If they could get it to stay in one place it would make their attempts much easier.

  • Tumrgrwer Tumrgrwer

    The reactors fuel load melted through primary containment, downward to the basement. What distance is that? Water and fuel in the basement is hot enough to creat steam as we saw on the endo. How much temerature is lost between the basement and the measureing devices? When you hold you hand over boiling water it will burn you, but if you raise your hand a couple of feet the heat disapates. alot. So the “Cold Shutdown” is nothing more than the thermometers are many yards away from the fuel.

    Let us be kind, one to another, for we are each of us together in our pain!

    All the world’s nuclear experts combined can’t figure a way to cork one power plant. Can’t do it.

  • dear jones

    Don’t worry TEPCO is directly pouring sea water to the thermometer, so it will cold down soon.

  • dear jones

    I think we put all pumper in the world together should have a better result than nuclear experts.

  • dear jones

    And they are much much cheaper.

  • Laterlukemayb Laterlukemayb

    THIS JUST IN! The world is breathing a sigh of relief as the worlds nuclear scientists, engineers, military generals confirm containment of all three Fukushima meltdowns. China reported this morning that all 3 meltdowns arrived with minutes of they’re approximated breakthrough to it’s continent where the meltdowns simply flowed into the 40ft thick Titanium containment vessels and were immediately sealed. Water was immediately poured on them where for so long they had evaded the efforts to cool them down. Never again in the history of this planet will we allow this type of evasion from out of control meltdowns to occur unimpeded for such a long period of time threatening the lives of biological life forms, stated the top military generals who coordinated the containment effort.

    • Laterlukemayb Laterlukemayb

      Just in case….this story is satire.

      • Sickputer

        Funny…although technically the antipode from Fukushima is off the coast of Argentina. *;-) Miss by a couple thousand miles and the corium might come out at the huge Nissan plant in Sao Paulo and ruin their lunchtime. *;-)

        The Chinese are the only super power who could probably fix the problem at Daiichi…if Japan’s leaders weren’t so arrogant about asking for help from them.

        • BreadAndButter BreadAndButter

          Unfixable by anyone….SP, did you see the pics of the recent cadmium spill in China? Image-google, and then think “Fuku”…
          Good morning btw!

          • Sickputer

            Yes…ugly scene in China…Six months or less and the firing squads will blow away the seven hapless plant executives.

            No air emissions though…>;->


          • Sickputer

            >Unfixable by anyone

            SP: I forgot to add…nothing is impossible…only improbable. Fukushima Daiichi could be contained if they threw enough resources at it. As I said the disaster is a titanic toxic war on the level of a Third World War and requires resources befitting such an event.

            Estimated cost of World War II:

            “Monetarily, in 1940 dollars, the estimated cost was $288 Billion. In 2007 dollars this would amount to approximately $5 Trillion.”


            SP: I stand by my estimate of $10 trillion to contain Daiichii (and that’s just to stop the island mess…another $10 trillion to help remediate some of the environmental damages in Japan…some is unfixable obviously for 200,000 plus years).

          Your comment shows the miserable lack of understanding of the ‘Middle Kingdom” and logics.

          1) It is not a super power. It is the most fraudulent economy in the world

          2) “Nothing is impossible” is a logical fallacy. It conceals the premise–“given time and space”.

          There is no solution for nuclear disintegration because homo sapiens have NEVER understood how nuclear reaction works. Nor have they understood how DNA works. Nor have they understood how a human body works. Nor have they understood anything.

          Your comment exemplifies that.

          The “good thing” is that the days of this species are numbered.

  • dear jones

    In order to make sure the cold shut down status of the reactor, I think TEPCO should replace the naughty thermometer reading with the one in the air condition office.

  • dear jones

    Now my home fish tank thermometer reading is 28 degree, I can sale this reading to TEPCO.

  • dear jones

    Are we living in the same planet?
    There are no so call main stream media care about this new !!!!

  • dear jones

    Now the temperature at the bottom of the Reactor Pressure Vessel at 80 degrees Celsius. I have told them to use air condition or my fish tank reading.
