Tepco Tackles Nuclear Reaction Threat as Fukushima Plant Temperature Rises

Tokyo Electric Power Co. injected boric acid into a reactor at its crippled Fukushima nuclear plant to prevent an accidental chain reaction known as re-criticality after temperatures rose in the past week.

The temperature of the No. 2 reactor was 70.1 degrees Celsius (158 degrees Fahrenheit) as of 6 a.m. today, according to preliminary data, Akitsuka Kobayashi, a spokesman for the utility, said by phone. The reading fell from 72.2 degrees at 5 a.m. this morning [...]

“It was too early to say the plant is safe in December. They declared cold shutdown even though nobody is sure about the location of melted fuel,” Tetsuo Ito, the head of the Atomic Energy Research Institute at Kinki University in western Japan. “A similar incident will probably occur again.” [...]

    Snarky comment: Hey, dude, they didn’t declare ‘cold shutdown,’ they declared ‘cold shutdown conditions’! Cold shutdown CONDITIONS include molten, spontaneously still fissioning, on the loose China Syndrome melt-through nuclear fuel/waste.

    Sincere comment: At least the point is being made that it’s not fair to declare cold shutdown when you still have molten fuel core on the loose.

    • I put this text in bold for a reason.

      I will continue to put updates such as these in a bold large text format.

      In my opinion we are all here to discuss this current crisis. Thus The updates of this nature deserve a large text. As they clearly are providing the most up to date source on record in light of current events…
      So It is un arguable in my eyes. Truly, I do apologize for your possible inconvenience from me using the large text format.

      • BreadAndButter BreadAndButter

        Hi Taco, I agree with you – we’re all here to discuss this current crisis. Everyone here has something important to contribute.
        I just find it not very polite to use bold typing, as it gives the impression to others that you consider your updates more important and they therefore deserve more room ant attention.
        To me, it’s like someone wrestling his/her way to the first row and grabbing the microphone.

        No offense intended, but maybe worth a thought?

        *peace

        Maybe, just post your comment that is on topic with the article and then at the end of your post you can write your updates, albeit normal font. We will still read it, as I like many others, are always interested in what you have to say. I think we should try, though, to stay mostly on topic in each thread. JMO.

          I believe Tacomagroove’s FREE information is sufficiently ON topic and an essential ASSET to the education of our many “browsers”.

          Are we attempting to WAKE FOLKS UP about what’s happening in our PRO-NUCLEAR GOVERNED WORLD, or quibble amongst each other about font sizes?

          Just READ IT FOR WHAT IT IS and move along, LIKE ADULTS.

    • ENENews

      OK, No more 30 pt bold text.
      If you have to do something, you can bold the text, but no increased text size.
      The html tags were only allowed in the first place so people can post videos and photos.
      I am thinking of getting rid of that too, as people are posting photos and video that are too wide, overlapping content in some cases. If anyone knows how to restrict the width of comment content please get in touch.
      Thanks for everyone’s cooperation.

      • gr81 gr81

        My opinion is: just leave it like it is. It seems very flexible and surely has the effect of being MORE INFORMATIVE for the visitor/browser searching for the truth.

      • arclight arclight

        how do i embed to show a smaller screen??

      • @ Admin

        You can adjust the frame size in your html. But each user must make the changes in their html before they post.

        A common html will say size =, or frame =

        That is where you would adjust the size width and height of the html on any: picture or video.

        P.s. If you took off the html; I would still be able to use it on your website ;)

        However, I will agree to discontinue to use the h2. format. Users need to realize this request would make it less likely for users to see the reactors live stream events.

        As I only adjusted the text during live events. So there was a need for it in my opinion.

        Yes its like running to the front of the crowd to grab a microphone.

        BUT THE BUILDING IS ON FIRE And ITS A GENEROUS THING TO TELL THE PUBLIC THAT INFORMATION

        Sorry to everyone that found it easier to get these updates.
        I prefer to be on admins goodside ;)

    If you are in Japan, it’s probably too late to get out.

    I would suggest that your government has not served you well.

    But every other government appears poised to do the same – so it’s not a problem with government.

    It comes down to people – people being honest and doing the right thing, rather than the easy thing or the popular thing, or the high paying thing – the right thing.

    i wish you good luck and good health

      It’s not too late yet for Japanese to escape, but that day is fast approaching. Has anyone heard if the royal family is hanging on in Japan? Just wondering if their children have been sent out of the island.

    • Spectrometising Spectrometising

      James2….I would agree that the hour is getting near. My theory about burnt soup and insulation etc….The hour has gone inverse exponential in my view.

  • Frances

    Rhetoric tells us everything. See below

    “It was too early to say the plant is safe in December. They declared cold shutdown even though nobody is sure about the location of melted fuel,” Tetsuo Ito, the head of the Atomic Energy Research Institute at Kinki University in western Japan.

    Note that the correct English world be: “was safe in December.”

    The shift to the present tense (even though qualified by “December”)is a nice indirect way to say:”The plant is not safe”.

    • anne anne

      They declared cold shutdown because that was a requirement before they could restart a reactor on the west coast. Kashiwazaki-Kariwa NPP was damaged by an earthquake several years ago and is on an active fault line. However, making money off this newly started reactor will keep TEPCO from going bankrupt. But another earthquake will be disastrous. It is hard to have to suffer the priorities of such a decision.

    Effects of recent releases across the country:
    the spikes in most prefectures shown on the atmc.jp site are quite impressive. See this one from Osaka measured at 20 m height:

    Note: Osaka is 630 km / 390 miles from Fuku.

    • Sickputer

      Wow! Got to be at least 10 times higher at ground level. Did anyone hear from Yoichi on Rense radio this week?

    • Hot Tuna Hot Tuna

      Pretty unimaginable. I’m sure officials were out in force giving downwind residents plenty of advance warning that this deadly plume was coming. Otherwise, the Government of Japan must admit they are murdering their own children.

    Aaahhh…liability (part 2):
    Power firms to install vent facilities in all domestic nuclear plants

    The Federation of Electric Power Companies of Japan said Tuesday it will install vent facilities in all nuclear power plants in Japan to enhance the safety of them by releasing vapor from reactor containment vessels when pressure inside rises in the event of an accident.

    The facilities will have a filtering function to remove radioactive substances from vapor before releasing it from the containers, Makoto Yagi, chairman of the federation, said at a meeting of the Atomic Energy Commission convened to work out a new outline of Japan’s nuclear policy.

    “Drastic measures” are necessary to maintain the public acceptance of nuclear power, Yagi said. “We would like to ensure local people have a sense of security (about nuclear power plants) by avoiding their long-term evacuation and contamination of the soil as much as possible” when an accident occurs.

    http://english.kyodonews.jp/news/2012/02/140425.html

    *Just vent it all instead of letting it explode!
    Slow & steady vs. quick & dirty

    • Sickputer

      Tepco: The masters of disinformation and misinformation. They can’t even filter water from Daiichi efficiently (nor the air releases) but they want to reassure the public they can achieve this technique at 50 other Japanese nuclear complexes.

      The Japanese people know Big Brother is a liar, but they want to believe in his lies because for virtually all of the people their lives have no escape outlet despite the severity of a national crisis.

      99% of the Japanese will accept their fate. 1% will leave Japan ( and half of those 1.3 million souls have already departed).

      Sayonara Japan!! The grim reaper is at your door as you read this. The next ball of rice, certainly the next small fish, and even the air you breathe is becoming oh so deadly. Die with Tepco’s assurances or escape to another land. Your choice.

      Death with national approval or a chance to live longer in Brazil, Shanghai, or America. A Hiroshima bomb is exploding EVERY day at Fukushima Daiichi. You will not survive 1,000 days of dirty bombs. Time to make a stand for your families. Your choice.

  • or-well

    Basements -
    just how many Olympic-sized awimming pools of water can any of these individual basements hold?

    One by one how full are they now?

    Anything down there that shouldn’t be submerged in (radioactive)water?

    Or is it just trunks full of kids old school projects, jars of homemade jam, the old stereo and a beer fridge?

    • aigeezer aigeezer

      I’ve been wondering about that too, and we haven’t heard anything recently about the huge barge brought in months ago. Surely it filled long ago.

      People here have speculated that they’re just dumping it into the ocean. Who knows, but the story has been “everything is almost full” for a long time, it seems.

    • Sickputer

      It’s not an issue of deadly “filtered” water storage anymore… That ship has sailed. I doubt they will buy and transport any more storage tanks. As you can see on the Tepco scam cams there has been a big nuclear event in the past 24 hours requiring massive water cannon usage to flood the plant reactors involved.

      That means millions of gallons of contaminated water flowing unimpeded to the ocean. There is nothing else they can do but try to put out the nuclear fires that can’t be extinquished by water. The heroic firefighters are doing their best against a situation no firefighter has ever been asked to contain. They are true 21st century samurai fighting against an enemy greater than mankind has ever faced. An alien Frankenstein monster enemy borne of scientists who knew the dangers and predicted this day many times in the past.

  • hbjon hbjon

    I think one thing is correct. The powers that be do not know where the melted fuel really is. I go back to what I was saying in another thread. When fuel melts in containment it may stay liquid. When fuel melts outside of containment it may vaporize. Liquid fuel will pool like molten lead at the bottom of containment and try to pass through any cracks because of it’s weight. Once outside of containment and exposed to the air and other elements, chemical reactions take place that will throw the Uranium into a vapor. If the SF is not contained, there may be large releases of the decay products, as well as the daughter products. There is a phenomenon that has been suggested that fuel will create a crust that will contain itself somewhat(that can be understood in a lengthy discussion). A small crack or hole would enlarge as the fuel flowed through it right? Perhaps what is not understood is what happens if large quantities of molten fuel builds up in the ground and evaporate all the h2o in its immediate vacinity and forms the crust. Perhaps the best case scenario in these dire times. Sure thing is it will happen again, because there is fuel that is still undamaged. Undamaged but unapproachable. Perhaps the barge is waiting for someone to invent a way to offload some of the fuel rods into it? Could there really be undamaged fuel rods at daiichi?

  • Bobby1

    Ito says nobody is sure about the location of the melted fuel.

    Arnie Gundersen says he knows where it is:

    “Question is how deep into the concrete it has worked it’s way and has it broken through the steel?

    I do not think it has broken through the steel and I think it is perhaps as much as a foot or two into the 3 feet of concrete

    I do not believe that the nuclear core can melt down through the containment and into the water table”

    hey all … just to let you know, my PRM-8000 always-on geiger counter woke me up today at 4:21 am (night from Feb 6 to 7, Mon to Tue) with the rad alarm levels set to 0.7 usv/hr … the “normal rads in my home here in South Korea, Chuncheon are 0.36 usv/hr … so I set the alarm to twice that … and it has not gone off in the last few weeks … until last night …

    I don’t know if anything happened at that time or if it was a fluke … since when I woke up and turned on the backlight on the unit the levels had “gone down” to 0.6 usv/hr … which is the “normal” high level (0.22 to 0.6 most of the time, indoors … outdoors it is around 0.31 at the lowest and goes over 0.7 on in some areas)

    also, it seems that I am living in a hot spot since when I went on a “rad survey trip” to Seoul on the weekend the highest rad levels I found were 0.28 usv/hr and lowest 0.05 !!! I had never seen such a low reading since I got my geiger counters (Inspector alert and the PRM-8000)

    anyways I just wanted to share.

    • BreadAndButter BreadAndButter

      Hey DukeNukem, haven’t seen you around for a while! I’m not surprised to hear you’re havin higher levels at the moment. Look at the rise during past days in Osaka, which might not be too far from you:
      http://atmc.jp/?n=27 (the measurement was taken at 20 m height!)

      *peace, take care

  • DukeNukem4ever DukeNukem4ever

    well, I have been keeping busy and counting the days until my contract runs out here so I can take off (without major financial losses) to Europe (got some family there) and get away from these high rads here … I got till the end of March … and hope against all hope that this situation in Fuku will at least hold on until then :-( … I will try to get out and about and get motivated enough to do some short movies around the neighborhood to document the high rads (eg: 0.5 usv/hr at the local subway station) … but I have been just too busy working and then cleansing and stuffing myself full of supplements along with keeping up my Yoga workouts and doing all that I can to avoid going out into the higher still levels in the streets …

    surreal times we live in … when I go to work I watch people in the streets … who are going about their business totally unaware of the impending doom … this is so bizarre … and of course no a peep about any of this on the news … at least for now we have had the good fortune of having the winds blowing out into the pacific … but a change might be looming … I dread to think about that … last time the wind “swiped over” us here the air was “hot” … lots of coughing and sick kids at school …

    anyways, thanks for the warm welcome (back) :-)
