Title: Spent fuel pool cooling system suspended at Fukushima Daiichi plant
Source: Kyodo
Date: April 12, 2012

A spent fuel pool cooling system was suspended Thursday at the No. 4 reactor [...]

[Tepco] is looking into the cause of the trouble, suspecting a possible water leak in the system, which was halted after the alarm was triggered at 2:44 p.m. [...]

The utility said the water temperature at that time was 28 C and is expected to rise by about 0.5 degree per hour while the cooling system is under suspension. [...]

      I tend to agree with you that spent fuel pools 3 and 4 are cracked and that the rods are already mostly (if not entirely) melted.

      I think that any cooling that has occurred has been a continuous feed-and-bleed operation (as Sickputer has described)

      What I don't understand, because it doesn't make sense to me, are the recent remarks made by Japanese diplomats and others about spent fuel pool 4 constituting a risk to civilization itself.

      If the pools are already destroyed, why these dire remarks now when they simply brings more mainstream attention to the conditions at the plant?

      The game that is being played makes no sense at all???

      I'm interested in your and other opinion of the stakeholders and their strategies.

      Obviously China, South Korea, the US, Canada, France, Russia and Australia all want the nuclear industry to continue so that makes sense. And the value of uranium futures has to be preserved.

      However, if we are indeed confronting a threat to civilization, why allow all these remarks to circulate publicly about that fact, particularly when they concern a situation that is already out of control…

      I am very puzzled… the entire situation makes NO sense…

          Majia,

          I have been asking that question, too, why now? It implies that there is worse news to come. I like Heart's theory about the declaration of victory, it makes sense.

          I can describe the effect of this tactic on me. Last spring, I had my bags packed and one foot out the door, but when Gundersen told the world that we would have to evacuate Tokyo, and "shelter in place" on the West Coast is SFP4 went down, well, ironically, I relaxed. I still had time to prepare, to get ready.

          Some thoughts:

          1. Even though this nation-destroying threat sounds horrible, it places the threat it the future. It defers the danger, the danger is not in the present, we still have time.

          2. It suggests that what has happened already, three meltdowns, melt-outs etc., are not that bad, nothing requiring evacuation has yet occurred.

          3. Fear is helpful to those in power. Today the bogeyman is not the communists, but the reactor 4 spent fuel pool. It is a narrative easy to control. Today a little bit worse, tomorrow a little bit better. Fear stifles dissent. Heros will arrive on the scene.

          4. The Shock Doctrine. Anyone uninformed who asks me about this news expresses the same thing, their helplessness about this situation. This potential catastrophe is shocking, renders the public helpless, and allows those in power to provide their answer.

          5. Cover. NRC transcripts revealed that the R4 sfp was "gone," and the drumbeat about the fear of the sfp4 started up again…

            6. Cover 2.0. Other bad things are happening now that will be blamed on the r4 sfp. Is this cover for the corium dust hitting Tokyo? Fuku II? Etc.

            I'm wondering now if the reactor 4 "temporary pool" (on the opposite side of the reactor from the spent fuel pool) somehow lasted until Dec 5, and that is what exploded and blew out the panels of reactor 4 that first week in December.

            7. Cover 3.0. Distract from the radioactive waste hitting the West Coast, the deformaties being reported in Japan and beyond, the "big threat" overwhelms.

        Dear Majia,
        With their contradicting information, they aim to discredit the oponentes. The fact is WE DO NOT KNOW,because the facts do not stick together. Or things they serve as facts. Godard and Gundersen and people like them are the targets! May be we can help by searching and pointing out contradictions. Step, by step, without affirmations. And we must guard the reputation of our experts. They have the honesty to examine things and explain why they think so.

        It's all designed to make the population think that everything is OK, as long as #4 survives. It's all about minimizing the public's awareness of how bad this truly is.

        The world's governments are deathly afraid of their countries turning into "The Road". Many people talk about "On The Beach", but it's the in-between time that's the scariest.

        We simply have to come to grips with this as best we can, help our fellow humans through this, and be ready for what comes next.

          I have to admit I don't have the stomach to read "The Road". It may have won a Pulitzer Prize, but there's a limit to how much I want to have pictured in my brain.

          And I won't go near the movie, either. Holy crap, things can get far worse than any of us can imagine.

          Very interesting that McCarthy would write this book five years before 3/11. What nightmares he must have now . . .

            @Time Is Short,

            Hello. Your mention of "The Road" prompts this.
            I read it. Although there is much of Love,
            and courage, and perseverance in it, it hammered
            me emotionally. It will remain with me for the rest of my life. It changed me.
            Perhaps strangeley, I don't regret reading it.
            I do regret not having done more in my life to preclude it's premise.
            I will NEVER watch the movie version.
            I think every nuclear psychopath on earth should have to listen to it read aloud. Over and over.
            I think it must have been difficult to write. I too ponder McCarthys'…reaction…to current events, and actually, the experience of writing it in the first place.
            I would never recommend it to anyone who already "knows" or "gets it". For the rest, it should be required reading.
            I quess this is pretty off topic. Oh well.

              I have thought of the movie "The Road" ever since 3.11 and imagine it as a very possible future for us all. I must say I have yet to read the book but plan to start it this week. If I may ask, do they attribute the start of their decline to a nuclear disaster in the book version?

                  Also, extremely realistic, very modern (recent) dystopian must reads….

                  PATRIOTS by James Wesley, Rawles

                  ONE SECOND AFTER by Prof. William Forstchen

                  Both offer extremely accurate portrayals of American life after TSHTF.

                  PATRIOTS is probably closer to our issue here, in that it deals with the aftermath of economic collapse.

                  The latter is nagging at the back of my mind a lot with regard to Fuku.

                  What happens when Joe Six Pack realizes that retirement planning is a lost cause?

                  What happens when it seems obvious that going to college is a total waste of time?

                  What happens when people decide they would rather cash in their 401k (the few who actually have much of one) and spend it than to roll the dice that it will actually be of any value, when "the long haul" becomes a thing of the past?

                  JIT manufacturing becomes a trap.
                  As a design engineer, I keep pondering control system theory.
                  Many systems that are "potentially" unstable require very small parameter changes to start oscillating. The real world applications typically break badly and abruptly or become useless.

                  The Mark I NPP designers/managers/accountants decided not to worry about the latter.

                  I am reminded of the sociopath accountant in the movie Failsafe who so casually calculated how long it would take after full on thermonuclear exchange for the GDP to return to "normal".

                There isn't really a decline depicted. It's more full-on, present-time (in the book) in-your-face BAD.

                It does seem to be a result of a nuclear exchange. That isn't really emphasized, and some readers who like things spelled out don't like that, but it is clear enough.

                My family sponsored two orphaned boys whose families had been killed during the civil war in Liberia, many years ago. From them we heard many terrible stories of the people turning to cannibalism as a form of intimidation. Parents were beheaded in front of their children. There is nothing in history to make us think people wouldn't utterly lose their humanity or be degraded to mere beasts.

                I don't think I can watch the movie or read the book. I'd probably have nightmares. I'm already waking up some mornings grinding my teeth, and having anxiety when I hear the latest round of bad news.

                Yesterday I was walking the dog and found a redwood tree whose tiny cones were all fused together, horribly mutated. Am going back with my camera and will post at Photobucket. Also — one of the trees in the neighbor's yard has all dying branches except for one single branch, on one side. The whole tree looks blasted, and it is barely growing leaves. The signs are all around us …. Granted it could be from diseases, and the plants' immunity might be lowered, as is ours. Maybe they're getting diseased. IMHO it's mutations. I've never seen anything like this. Ever.

Gotta love it, Or-Well! :-D I believe we need to teach kids how to become critical thinkers and learn to think for themselves and make sound decisions by weighing the options carefully. Too bad those in our society who went along with toeing the nuclear line did not have those skills, or they might have questioned the sanity of the orders they were given vis-a-vie nuclear.

        The lack of clarity makes me insane.

        Transparency is so important to a well-functioning, democratic society.

        Obviously we have failed to materialize our ideals.

        I think this is our last opportunity to demand transparency, accountability, and cooperation before it is too late.

        I do think more and more people all over the globe have come to realize that we had better reform our governance of star ship Earth…

        but too many people still doze (sedated by consumer culture) or are too mired in poverty or greed to stir…

          " … What I don't understand, because it doesn't make sense to me, are the recent remarks made by Japanese diplomats and others about spent fuel pool 4 constituting a risk to civilization itself.

          "If the pools are already destroyed, why these dire remarks now when they simply brings more mainstream attention to the conditions at the plant?

          One possibility in my devious view is that- as we know- Tepco have just asked for a very big sum to go towards remediation. We all have a view as to the amount the company is into in terms of compensation (can be estimated) and remediation ("if the technology can be invented" == completely unknown). I am sure that Tepco is an organisation with an excellent moral compass (warning:may contain traces of gullibility) and could never stoop to the cheap trick of frightening the powers that be with AAAAARMAGEDDON in order to get hold of a "little spare" cash to cover some outgoings they know about and hope others never will.

          In this…

            In this scenario an unscrupulous company totally unlike Tepco (warning: etc.) would naturally have got the friendly big players onside before putting out the frighteners.

          Majia, I was thinking about this, this morning. I'm beginning to wonder if it's true many people are chemically lobotomized by fluoride, GMO's, excitotoxins, pharmaceuticals, and the mind-numbing apparatus known as "television."

            I wonder too, HoTaters. Did you see the news today predicting a three-fold rise in dementia in the years to come? Granted, a big population of aging Baby Boomers is part of the reason for the projection, but I believe an ever-increasing exposure to environmental toxins, including radiation, is contributing to the degradation of our brain cells and our ability to think clearly. Also, a recent study about causes of autism showed a link between genes that had been compromised in the parents (especially older dads) and the rise in autism.

            And knowing what we know about radioactive fallout continuing to circle the globe in the upper atmosphere, even from past above-ground atomic tests, Chernobyl and now, Fuku, there is no doubt in my mind that our pilots and airline attendants are receiving increased doses of radiation exposure. The two separate recent occurrences of a pilot and in a separate incident, a flight attendant having psychotic breakdowns made me seriously wonder if their brains were not able to handle the radiation levels they've been receiving. :-(

        This just posted on ex-skf…TEPCO press release of 'supports' under SFP4 from June 2011: http://ex-skf.blogspot.com.au/2012/04/for-record-fukushima-i-nuke-plant.html

        Ahhh…I feel SO MUCH BETTER…those steel matchsticks will withstand another 1000 major quakes…

    It only goes up 0.5c per hour with the cooling off, unless there is a massive leak it will take days for the pool to be a problem.

    This does not make sense me, but then I am not a nuclear scientist.

    I just know these things are to dangerous to be built.
    Once accident or leakage is one to many, and we have had more than one.

    If this thing collapses, there will be no substitute for having your own meter, and also knowing how to use it.

    And for the first time since 3/11 I have seen a price drop in the price of Inspector Alerts, on Amazon with no shipping or sales tax.

      This free Geiger Counter Use Guide has been put together to help those here who have just purchased a Geiger counter. It has basic info on how to get the best out that new Geiger Counter. It also has info on how to prevent accidental contamination of a Geiger counter.

      I picked up some hot particles on a parcel delivery yesterday, with my Geiger counter. A friend picked up a contaminated batch of tea bags a few days ago. If a Geiger counter picks up food contamination, it is generally pretty contaminated.

      Last year another friend detected contamination on a newly purchased music CD, and a chocolate bar. You just have to test everything coming into your house.

        These detections where all by people in the southern hemisphere!

        Vital:
        Thanks for such a distinct post.
        I have not heard of anyone (yet) outside of Japan having detected anything other than the more specialized instrumentation set ups.

        I just had the misconception that contaminated items/products outside of Japan would not be detectable with the kinds of detectors most of us have.

        I will start measuring now.

        I am on the west side of Oregon (USA) and have taken maybe 5 or 6 different readings outside after rains over the last 12 months and have never detected anything that would have qualified as relevant.

        This is going to get very interesting soon, I guess!!!

    Yes, a meter is very important to keep now. Two is better. Price drops reflect the shut down in the media about this. The world is asleep again. Prices will skyrocket as soon as people wake up. The pools according to our our favorite expert are critical. We just had two more earthquakes over there, what's to come and is it not significant that this story enters the picture just as the quakes hit? Is this old, new or different? Are we going to see another shake up within days and if so, where do we go at that point? Also… this site is now blocked on Facebook! Try to post something and you will see as I did. The wagons are circled.

    Off topic: does anyone have any experience with the PRM-8000? It appears to have less sensitivity than the Inspector, but it can run continuously and internally stores the data. It's about the same price.

    For any radiation coming our way from this fuel pool or elsewhere at the site, more sensitivity in a meter is better, even if it costs more.

    Furthermore, Fukushima is a considerable distance away, and meters will be looking for trace amounts of radiation. Also, not all pancake tubes are the same size, which can lead to different CPM counts on the same items. If you want to be able to mentally interpret the CPM results of others, your meter should be of the same brand.

    Quote: Possible Leak at No. 4 Spent Fuel Pool

    POSSIBLE?????? Give me a break..This has been a continual feed to cool it.

    I would say they have to fix this from underneath not on top. How far down do they have to go, will the soil hold, is the area to hot, is it unfixable, who knows??

    This disaster has effected so many already, and will keep on effecting people.

    That's ridiculous.
    SFP 4 got leaks/cracks since the detonation in unit 4.

    I don't think that SFP 3 was only damaged. It doesn't exist anymore.
    The crane gone airborne hundreds of meters. Tons of steel. The pool got exploded for sure. There is no other explanation for that physical effect. The initial blast was in the south location of Units 3 Rooftop, right under the SFP – created a vacuum and the plume went up.

    Unit 1 SFP also have cooling problems because the rooftop lays in/on it.

    Lies Lies Lies…

    • from video and soundtrack from Arney, there was no fuel pool, all boxes out of water, a video yesterday someone posted from last year and news reports that there was no water in pool . separate video !

      I think the worse case scenario came and went and still burning !
