196 comments to Remaining portion of Spent Fuel Pool No. 4 seen from Kyodo helicopter (PHOTOS)

  • I am re-posting a comment made by James about spent fuel pool 4 at my blog:

    As we discussed a couple days ago, the SFP4 is indeed still intact.

    Let me describe a few things from that picture:

    1. The approximately 150 foot tall building has been cut down to now 100 feet tall. All the structure above the reactor floor has been exploded off or removed.

    2, You'll notice there are 6 "bays" and 7 columns in the north south direction of the building. (The end you see is the south end and the north end is to the right) The building is also 4 bays wide and used to be 5 bays tall. They have removed the top 2 bays of the building. Each of the bays is approximately 25-30 feet wide. So the building now stands 3 bays tall, or 90 feet, it stands 6 bays long or 180 feet and it stands 4 bays wide or 120 feet. (In reality the East/west bays appear slightly skinnier so more like 100 feet wide).

    3. The Excavator is sitting on a platform that is directly over the reactor core. The base of the platform is at the level of the "reactor floor" – which is actually above the top of the reactor. The yellow thing is the containment dome which bolts to the top of the contaiment and there used to be a slightly smaller diameter Reactor pressure vessel cap that went inside it and sealed the RPV. It used to be in the wreckage, but I don't see it here. They must have removed it… cont.

    • cont. Notice the reactor itself is not centered in the building, but offset slightly to the south and to the east of center. (this is not important for reactor 4 analysis, but very important for reactor 3 analysis)

      4. The spent fuel pool is under the steel plate behind the pink box. The top of the pool is at the reactor floor level and as you state it is approximately 45 feet deep , in order to accommodate moving the 12 foot long fuel assemblies into the reactor while they are kept completely submerged. So the SFP only goes halfway down to ground level in this photo. You can actually see on of the outside walls of the SFP through the opening in bay 1 on the SE corner of the building. The hole on the south wall at bay 3 was blown out in the explosion, and you can see the SFP doesn't extend that far. Somewhere in that vicinity is the elevator where they bring fuel up to the floor level.

      5. On the other side of the reactor – the north side, you see the green refueling crane, which rides on tracks in the floor back and forth to the north and south. (or at least did at one time). Between the crane and the platform that covers the reactor is another steel plate, covering another pool, the machinery or equipment pool. This pool is smaller than the spent fuel pool. It's also where I think the explosions occurred in this reactor, and where I think the danger is. cont.

      • cont
        It's also where I think the explosions occurred in this reactor, and where I think the danger is. Notice that the end of the building around this pool is very much devastated by explosion and fire – with the exception of the crane which was actually on top of the SFP after the accident – it's been moved to this location recently.

        The reports in March 2011 of a "fire" in reactor 4 described a "machinery fire". I believe now they meant a "machinery pool fire", and that means the machinery pool had something in it – something very explosive – and I believe that something was new MOX fuel that they were about to load into the reactor. They claimed the #4 SFP did not contain MOX – that is technically correct if the MOX was in the machinery pool, not the SFP – but really misleading.

        6. You are correct but maybe not completely correct in worrying that the bottom of the SFP is 45 feet above ground level. It's dangerous for all pools of this size, because it makes it nearly impossible to remove the fuel in this scenario. However you are not correct that this #4 pool is unstable from the bottom. During June and july 2011 they installed reinforcement to the bottom of the pool – there was a document released on November 17, 2011 called "Progress Status Classified by Issues (Photos and figures)". On page 35 of this document, there are photos of the steel and concrete reinforcement placed under the pool. It's extensive enough that I have no worry about he pool…

        • I'm more worried about the makeshift cooling system breaking down and/or the water leaking out of cracks in the walls or leaks through the gate between the pool and the reactor.

          And I'm extremely worried about whatever is or was in the machinery pool. In the video of the criticality on June 30th, something in that very vicinity lit off and was glowing more brightly than the initial criticality.

          And finally, you are correct that SPF3 is not intact.

          I reported on numerous occasions that it was on fire starting in November until at least March or so. I also reported that the south wall of #3 had partially collapsed and a "river of corium" was running out of the collapse. All true. At one point they actually spray painted the corium in order to hide it from one of the media tours. Now I believe they've build a construction wall in the gap between #3 and #4 buildings to hide it from any of the photographs.


          • Points from James [℅ majia]:

            5. I agree that it looks very much like the explosion may have originated in the equipment pool, which in fact appears to have been destroyed – no evidence of its wall, which should be visible like the SFP wall is. Also agree the refueling crane has been recently moved to straddle that pool (over plating). Maybe a little extra shielding?

            Yes, "machinery fire" was probably a deliberately deceptive description of fire in the machinery pool, with "pool" left out. If there were MOX assemblies in that pool, the fire could well have been there because the pool itself (or at least the eastern – seaward – wall) ain't there anymore.

            The active core that was in the SFP was reportedly NOT "checkerboarded" for long-term storage, presumably because they intended to put it back into the reactor as-is when maintenance on the shroud was done. That would seem to negate the need for fresh fuel in the equipment pool. Of course, since the core was in the SFP they may have planned to go ahead with refueling when it was returned to the reactor, along with reconfiguring to burn MOX. THEN they could "checkerboard" the older removed assemblies for long-term storage. With TEPCO, all things are possible…

          • At any rate, if there were assemblies (MOX or UOX) in the machinery pool, it's corium now somewhere in and underneath the unholy mess we can see only the outside edge of. That would seem to make any approach toward the eastern (seaward) side impossible due to gross gamma/neutron radiation levels. They do not in fact appear to be approaching that side of the building, though remote machinery may come and go – looks like they're allowing that open side to just be, not removing debris.

            I am not impressed with the glorified jacks and beams holding up the bottom of the #4 SFP. They appear quite flimsy, and not anchored to actual ground-level. Thus dangerous in an decent quake, though it does seem to have survived a few that begin to approach the ~6.0 the original quake generated under these plants. So it must be better than it looks…

          • 6. How the @#$! do you "spray paint" a flowing "river of corium" to disguise it from tourists? Photos of what (I think) he's talking about looked to me to be water, not molten metal. Though undoubtedly highly radioactive, necessitating a shield wall so as to enable workers to get to the #4 fuel floor without immediately dying. Corium actually was visibly present coming from a broken pipe in the wreckage of #1 early on (first drone fly-by). Or maybe that was just a loose assembly in the red-hot process of melting, hard to tell. Whatever form it was in, it was fuel.

            Moreover, who the heck would they get to "spray paint" it? Humans would be dead before they could push the nozzle. And what kind of paint can 'disguise' molten metal without becoming one with the molten metal? Some details on this assertion are necessary, as it sounds pretty far-fetched to me.

            Anyhoo, thanks for reposting here, majia.

          • In reactor 4 I am most worried about the amount of weight intake that the reactor is suffering from…

            So far there is a 35 ton crane located inside the fuel pool itself
            A 60 ton platform located above the pool…
            And probably another couple tons give or take on top of the platform…

            Then add the tonnage of the water which is probably anywhere between 1 and 60 tons…

            How much weight was the reactor sfp designed to support in the first place?
            Thats just a bad recipe being tokyo seismologists in 2011 predicted another huge quake within 3 years…

            Its like balancing a 2 pound weight on top of an egg…

            • patb2009

              the added weight is probably a wash compared to all the stuff blown off.

              my bigger issue is are there any critically cracked columns from the quake.

              if some of those are hard cracked, then the damn deck may give in

    • WindorSolarPlease

      Thank You majia

      We are all in a fine mess of a mess.

  • demo demo

    BOTTOM LINE–when/if #4 SFP goes, how much time will we then have to either "shelter in" or evacuate from: 1.Tokyo 2.Hawaii 3.California 4.northwest US and Canada 5.eastern US 6.europe 7.Africa 8.India 9.Asia etc. It will depend on the jet stream direction & speed at that time, so–to plan–we need best and worst case scenarios for each location.

  • patb2009

    so Asahi sent a chopper over, so where are the pics of unit 1, 2 and 3?

    Where are the big pics showing the SARRY water treatment facility?

    What is going on here?

  • islandboy9

    can somebody tell me where SFP that was covered with a white tarp & 60 ton lid in this photo???

    • demo demo

      "The spent fuel pool is under the steel plate behind the pink box. The top of the pool is at the reactor floor level and as you state it is approximately 45 feet deep, in order to accommodate moving the 12 foot long fuel assemblies into the reactor while they are kept completely submerged. So the SFP only goes halfway down to ground per. (thnx Majia & James)

  • Sam Sam

    So how many tons of mox fuel got released from the machinery pool fire -explosion in
    Unit 4. assuming that it was the load to go into the reactor core? These figures are
    important as we are so alarmed about SFP 4 and yet no one has grasped the fall out
    effects from this machinery pool fire . We could be in a world of more harm than we
    already assume. .

  • sonnen.blum.239 sonnen.blum.239

    we likely already are. Take a look outside in this 105 F degree heat in the midwestern US, and not much is surviving. Without rain, the fallout merely circles aloft and does not descend, spreading ever further destruction when it does. Stock up now, and the sheeple will panic when the truth is known. I for one, do not know what that truth is. But my gieger counter gives me an indication of how sick this atmosphere really is.

  • Andres Arce Andres Arce

    Scares a bit that no nuclear-worker is seen around this time.

  • islandboy9

    before 6/17 SFP4 was at the top of that building covered in white tarp & 60 ton lid. So where is that special crane to help lower SFP under this PINK BOX??

    • flatsville


      Study it. Look at both views…left side and right side.

      Start with the left. See where it says crane rail? Note the roof line is one bay above that…

      Now look at the right. Note the top edge of the SPF begins about one bay below the crane rail line and immediately below the line marked service floor.

      The steel plates in the recent photograph are resting/spanning the service floor.

    MARCH 18 Radiation hampers efforts to restore power to nuclear plant in Japan March 18, 2011|By Thomas H. Maugh II, Los Angeles Times

    Efforts to try to restore power to reactors at the Fukushima Daiichi complex are interrupted as high radiation forces the withdrawal of workers. But it's unclear whether a return of power will help. Spent fuel rods remain the biggest concern…

    …Reactor building No. 4 is now the source of the biggest concern at the site because it contains spent fuel rods that may have boiled dry and are releasing large amounts of radiation into the environment.

    Workers made a second series of attempts Friday to cool the fuel rods, dumping water from helicopters and using water cannons operated by Japan's Self-Defense Forces to spray water into the pool, which sits in the upper level of the building housing reactor No. 4….

    …But photographs taken by helicopters and a Global Hawk drone operated by the U.S. Air Force indicate the water is not lasting very long in the pool, suggesting that there is a major breach in the walls of the vessel holding the fuel rods, according to the U.S. Nuclear Regulatory Commission.

    • Sam Sam

      Excellent historical research. There seems to be no containment left of the machinery pool.
      So where is the fuel——where's waldo in that mess. Vaporized, melted down and out?
      I would hazard a preliminary guess that with Unit 3 exploded and machinery pool fire of
      Unit 4 we are in deeper in the danger zone than assumed so far –especially Japan.

  • My personal opinion:

    Spent fuel pool 3 and reactor 3 were destroyed rather completely. This has never been confirmed but looking at early reports reveal NO specific info other than water cannons were used on this reactor.

    Additionally, the early reports from Maugh at the Los Angeles Times stated that fuel at unit 1 was 70% destroyed (3/15

    We now know that reactor 1 is a full China syndrome.

    IMPORTANT We have never been informed of the status of the spent fuel pools at reactors 1 and 2 nor have we been informed of the status of the common spent fuel pool.

    We've never been informed of the real status of Daini:

March 11, 2011|By Thomas H. Maugh II and Ralph Vartabedian | Los Angeles Times

    • We've never been informed of the status of other reactors in Japan

      [Excerpted] Jim Walsh of MIT's Center of International Studies agreed that these reactors will probably be OK. But there are other facilities in Japan that produce enriched fuel for reactors and manage highly radioactive waste, some of which are in remote areas in the north, "and no one has said 'boo' about them," he said. "It's not inconceivable that some of them have had problems. The story may continue to unfold in the next few weeks."

        The status of the plant is summarized by speaker: he states the status of the plant has progressed to at least
        "2 reactors [in meltdown], multiple spent fuel pools and maybe 4 reactors and 4 spent fuel pools…."

        The prognosis is considered grim: “We’ve just not seen any mitigation of any of the events and we would take all the spent fuel pools and probably all the four reactors into the final conclusion because we’ve not seen any mitigation… (page 215 March 16) ”

        • FUEL at Daiichi

          A November 16, 2010 report titled “Integrity Inspection of Dry Storage Casks and Spent Fuels at Fukushima Daiichi Nuclear Power Station” asserts that approximately 700 spent fuel assemblies are generated every year. The report specifies that 3,450 assemblies are stored in each of the six reactor’s spent fuel pools. The common spent fuel pool contains 6291 assemblies.

          The amount of Mox fuel stored at the plant has not been reported. One source suggests that unit 3’s reactor core contained a range of 164 to 32 mox assemblies. The low-end estimate of 32 mox assemblies is from France’s Areva, which provided the fuel for unit 3. As the French Fukushima 3/11 Watchdog group points out, the low-end estimate of 32 mox assemblies translates into 5.5 tons of fuel containing more than 300 kg of plutonium: “300 kg is therefore equivalent to 300 billion lethal doses.”

          • This disaster is so BAD that we will never be told the truth.

            Arguing about 4 is just an intellectual exercise because it contained a mere fraction of the fuel at the plant, plus we know that some of it burned in March of 2011 and probably again in June of 2011 (and maybe Nov of 2011)

              Majia, I agree – who knows how much they are hiding. Already their mortality and illness stats must have jumped significantly, not just in Japan but certainly HI and in the US & Canada.

              Yes, we need to know and have a right to know what the fallout is/has been/continues to be – not only in these areas but in the Southern Hemisphere. Some of us possibly could leave our contaminated location for a less contaminated one, but it seems foolish to do something like that without at least some information re the safer/least affected areas.

              We know they are recording such information – because this, like Hiroshima/Nagasaki and all of the 'tests,' is among other things an ongoing 'experiment' – in which we and all life in in the affected areas are the 'experimental subjects.'

  • Looking back at the news reports from march 12-19 I find statements that reactor 4 pool has no water but that helicopters would be able to douse it because the pool was open, i.e., had no roof.

    I've put the details citations for these assertions in the webcam discussion forum.

    Does that mean that the pool was at the roof level?

    If so, that means no more pool at 4.

      Please refrain from stirring up confusing and misleading information. We all know what the floor plans are and what the blueprints say, yet you keep inserting doubt and speculation into the mix… THAT'S TEPCO'S JOB!

        Thanks for those links yesterday. Too bad people aren't paying any attention to them.

        I was in law enforcement and had to learn to read blueprints for search and rescue purposes. Sense of scale is a hard thing to determine.

        The photos you link helped a great deal as well.

        Do you agree those steel plates are probably resting on the service floor noted in the blueprint?

      • I'm NOT trying to insert doubt Max

        I'm just trying to make sense of the conflicting reports.

        I really don't know what the floor plans are, to be totally honest. Please link.

        Every news report that I looked at today from the period of March 11-19 the reported that most, but not all, the pools were on the upper levels.

        One report stated that pool for 4 was on levels 3 and 4.
        SOURCE: Takao Yamada. Fukushima Danger Continues.The Mainichi. 2 April 2012


        Going through the early reports reveals a lot more damage at a lot more places than is being recognized officially now

        I've written over 100 pages and spent over a year trying to document this mess Max and the answers remain equivocal.

        I have very good research skills.

        • Max1 Max1

          Sorry for the late response.
          I meant no ill harm toward you, personally by my observation.
          Earlier in this thread I answered nedlifromvermont with the floor plans link's shortly after I answered you with a description of the basic floor plans. I thought you had seen my responses.
          Sorry for any confusion.

        • Max1 Max1

          "I'm just trying to make sense of the conflicting reports."
          I agree 100%.
          There are many conflicting reports AND interpretations of events. Usually, the truth is right in front of our eyes. TEPCO is trying to "save face" with grace… The government has just exposed itself to the world as being complicit to defrauding the people of Japan of safety regulations that were put in place to GUARANTEE nothing like this could or would happen.

          The truth in all of this is:
          Secondary containment FAILED when primary containment of R1, R2, R3, FAILED and secondary containment FAILED on R4 because by design, that secondary containment was meant to be the ONLY containment for the SFP. It failed ALL safety designs BY CODE.

          Proof that Mark Reactors are vulnerable to FAILED containment systems as witnessed by Daiichi. Yet, many remain in operation.

          Sorry for the rant, thanks for the ear/eye here. We're on the same side. That much I do know for sure. Stay strong and keep up asking questions and posting observations. They ARE valuable.

    • flatsville

      SPF4 was never at roof level. According to the bluprints, the very top edge of the SPF began two bays down from the roof.

      See the blueprints Max1 posted yesterday.

      It is a sense of scale problem. I think those steel plates are resting on what is now labeled the service floor if you look at the above link. See the bluprint image on the right to understand why some are saying the SPF is under the plate by the "pink box".

      Look at every link he posted to get a better sense of the scale of the building–

      • thanks Flatsvill

        that is consistent with them being reported as being on levels 3 and 4

        However, the initial explosion must have destroyed the top bays because the reports are very clear over and over again that helicopters and high pressure hoses were able to get water into the pool.

    Aerosolized plutonium, uranium, etc., is not only injuring infants and other creatures in Fukushima and Futaba today, but in a location near you, if not now, eventually. So much MOX and other fuel is outside out any control/containment, that there are massive releases of radiation ongoing, everyday, into the air as far as Lithuania and beyond, into the ocean, lapping up on the shores of the Pacific Rim countries, then onto dinner plates around the world and back into the air with radioactive fog, moving steadily into other oceans, etc….

    • omniversling

      Destroyed to what level? Not functional, for sure, but the gantry crane structure was, and still is, there on that level. It appears to have been pushed back to the other end of the track. Here is a clip of the gantry structure above the SFP immediately after the explosion.

      Are you confusing the gantry crane which appears to be IN SFP3?

      • Radio VicFromOregon

        That's what i'm thinking, too.

        • flatsville

          Yep. It's confusing at best.

          Combine bad reporting on the part of the press and no reporting on the part of TEPCO with the inability to understand the difference between a crane rail, crane gantry, SPF crane etc…and people who can't read a blueprint and it's little wonder nobody understands the condition of the building.

          People also don't seem to understand that the service floor has large openings to access the SPF, reactor well and the tool pit. The service floor plane in not a solid piece of flooring…hence the need for steel plates to span the gaps,

          SPF4 is definitely in trouble and not holding adequate water. It could be cracked and even listing, but not fallen in.

          The readings would be screaming the news.

    Once again, please google FOOTAGE OF GOV'T OFFICIAL AT FUKUSHIMA INSPECTING SUPPORT POSTS UNDER SPENT FUEL POOL NO.4 (VIDEOS) it's a enenews story 4/27/2012. watch this and you find out THOSE PHOTOS ARE FAKE!!!
    the pool COLLASPED 6/26……

    • Radio VicFromOregon

      islandboy9, i'm trying to understand your claim. Maybe you mean the pool in Reactor 3? The crane fell into the pool in Reactor 3 SFP. But so far, nothing has collapsed or crumbled to the ground that i can tell from all the evidence combined. Given the amount of radiation that would be released immediately into the atmosphere and linger for thousands more if SFP4 collapsed, there would not be this discussion. It would be evident. It is not evident. We can not rely on poor video as proof, especially given the debris removal and restructuring that has gone into this building. We MUST rely on scientific evidence in testing for radioactive isotopes. Such isotopes don't just fail to be there one moment then suddenly appear, and are gone again the next time someone looks. They are traceable, trackable, measurable, and if what everyone is saying is true, many of the worst ones tend to hang around for hundreds, if not thousands of years. So, if what you are saying is true, that the SFP4 collapsed in mid June, where are the rad readings? Begin with the pile of broken and burning fuel rods that would be in the Fukushima parking lot, then go out from there, past Tokyo, keep going. Not elevated, or higher than ever before readings, but, off the charts rad readings. Where are those? Show us those and I will completely go with your theory.

        >>>So, if what you are saying is true, that the SFP4 collapsed in mid June, where are the rad readings?<<<

        I agree. And Yoichi Shimatsu's "non explanation" in the rense interview of why we are not getting such readings was bizarre…something about how the particles were mixing high in the upper atmosphere causing a rash of storms in the US???

        At some point all that crap comes down in the air or the rain out. It would be measurable in the hasn't happened…they'd be screaming "FUEL POOL COLLAPSE!!!" There would be do doubt about what happened.

    Yoichi Shimatsu with another great analysis of the 7/7 status of R#4 and the reasons for the necessary 6/26 demolition derby.

        Corrected link one more time:

        • Sickputer

          Good analysis by Yochi. I think the danger of implosion for the Unit 4 building is a distinct possibility…and an earthquake probably won't cause the collapse, it is already well on its way to self-destructing.

          The Japanese leaders probably have been told that the odds for stabilizing Unit 4 are very low. The Sword of Damocles is poised to fall on Japan and with it the Northern Hemisphere. Hopefully they have some engineers who can beat this pool collapse, but they better act fast. Unfortunately we know Tepco has three speeds: slow, slower, and slowest.

    NRC guidelines for Spent Fuel Pond water requirements:

    "The water-pool option involves storing spent fuel rods under at least 20 feet of water, which provides adequate shielding from the radiation for anyone near the pool. The rods are moved into the water pools from the reactor along the bottom of water canals, so that the spent fuel is always shielded to protect workers.
    About one-fourth to one-third of the total fuel load from the pools is spent and removed from the reactor every 12 to 18 months and replaced with fresh fuel.

    Current regulations permit re-racking of the spent fuel pool grid and fuel rod consolidation, subject to NRC review and approval, to increase the amount of spent fuel that can be stored in the pool. Both of these methods are constrained by the size of the pool."

    SP: Belated answer to Friday question from Majia: "How can this building hold an intact 45 feet deep swimming pool? Do you think it can?"

    SP: Steel floors are tough and if the huge thick walls were OK it would have no trouble holding even that much fuel, water, and even the crane that fell in. But I doubt the walls are holding up under so much thermal and nuclear bombardment. Maybe the water level has dropped or the pool tilted as Yoichi suggests on Rense, and if so the problem may be rushing to a climax. I hope the pool covers were for protection from the upper wall destruction by crane and not to hide a serious issue.

    • Radio VicFromOregon

      SP, i believe you are correct about the water level dropping. I think it is far lower than they want, but still covering the rods by a few meters rather than the 30 feets or so that it is designed for. The pool leak must be above the current water level. The upside of this downside is that the lower the water level, the less weight on this precarious and heavily damaged structure. But, when the circulation pumps or pipes have leaks or are down, the water starts to heat up fairly rapidly and steam increases, lowering the water level. So, TEPCO keeps the tall water crane thing they used in the first days of the crisis after the explosion in building 4 just on the other side of the pool wall for emergency filling.

  • Radio VicFromOregon

    And, yes, Arnie had said the tarp was to keep debris AND workers from falling in as they cleared debris, and also begin to construct whatever they plan on using to lower the dry cask into the existing pool. The steel plates are probably part of that protection, but, maybe they will also be supporting something heavy?

  • Andres Arce Andres Arce

    "(quake-caused liquefaction, erosion by the tsunami, incessant water leakage and melt-through of escaped nuclear fuel)
    Engineers therefore had to push back the TEPCO plan to remove two fuel rods from Reactor 4 in this month of July."

    hello everyone, check at the google custom search on ENENEWS FRONT PAGE. Published 04/27/2012 FOOTAGE OF GOV'T OFFICAL AT FUKUSHIMA INSPECTING SUPPORT POSTS UNDER SPENT FUEL POOL NO.4(VIDEOS) this video will show you the ORIGINAL LOCATION OF SFP4 white tarp water all, WHICH WAS ON THE FIFTH FLOOR! THE ORIGINAL LOCATION OF SUPPORT POSTS UNDER SFP4 WAS ON SECOND FLOOR! as you can see on the photo,SFP4 IS ON THE SECOND FLOOR(very strange) IF you take the time and cross exam the photo and video, you see photo layout is off from north to south east and west of the building! THE PHOTOS ARE A FRAUD!!!!!

  • islandboy9

    adding to this jnnlivecam has no visuals for days! so i checked tepco livecam and i see alot cloudiness around reactor3 this next to sFP4 location. PEOPLE we may not ever get true visual of SFP4! that why i'm saying SFP4 caved within the building 6/26 THIS IS A MASSIVE COVERUP BEFORE ARE VERY EYES!!! PLEASE checkout the FUKUSHIMA DIARY STORY BELOW…( RADIATION READINGS ON WEATHER FORECAST OF FUKUSHIMA). add em up people!!!!

    • Radio VicFromOregon

      islandboy9, so, please, what would be the rad readings if this happened? There would be astronomical radiation, correct? I get that you believe the building is gone, but, here is my difficulty. No rad readings. And, no, they wouldn't all disappear into the upper atmosphere. Some isotopes would aerolize in the fire and climb in a smoke column, but, most would stay right there in the parking lot in a big molten heaping pile of melting, refissioning nuclear fuel rods. Why should i put my trust in you? You are anonymous and are reticent to provide evidence? None of these links point to evidence or some don't even work. Why trust your assessment and not the assessment of scientists, doctors, engineers, physicists, people on the streets who are all openly risking their reputations, their jobs, their families to get the truth out, truth combined with tangible, measurable, independently verifiable evidence collected and tested by several unrelated people and in different places. The reason why this is important is because in times when lies are the norm, people must find other means to seek out the truth, often at their own risk. Are you really suggesting that we have all been duped, not just by TEPCO, but by all the scientists and antinuclear activists that have joined with us to help?

      • flatsville

        I don't live so very far away from these folks conducting independent air and rainout testing here

        I believe they are conscientious and well-meaning.

        12x Background Radiation In 7/8/12 STL Storms<<<

        Unfortunately, nothing unusual about 12x background.

        From the middle of June…39x background was high average, but well below the highest readings.

        >>>Sunday, June 17, 2012
        39X Background Radiation 12 AM 6/17/12
        Prior to Fukushima hitting ground water in August 2011, this paper towel swipe, from a piece of sheet metal, would have been in our top 5 highest readings ever. After August 2011, in the new normal, this reading is only high above average. Our highest reading ever was 276X background radiation.

        However, there is an additionally troubling thing about this reading and that is that the jetstream is several hundred miles north of Saint Louis over Minnesota. With a reading of 39X, we would expect the jet stream to be directly overhead.

        On a positive news side, we did not notice any elevated airborne radioactivity while we were conducting the sampling process.<<<

        So, there you have it. I would think if SPF4 had fallen through the building, these recent readings from rainout would be much different.

        (I don't doubt for a minute that there's serious trouble with that pool…leaking,yes…perhaps listing, yes…hasn't fallen through or crumbled to pieces yet.

    Wonder if the sudden activity (destructo derby, endoscope of Reactor 1 and such) is due to external pressure from other governments. Those robots used (at least one of them) came from the US thinking someone gave the Japan/TEPCO joint company a kick in the tush to get something done. HOPE more is completed before we are all "toast". Hope dies eternal.

  • Radio VicFromOregon

    jec, Senator Wyden from Oregon flew over to Japan mid-April and asked TEPCO and the Japanese government for a tour of the Fukushima NPP. What he saw frightened him. He returned to Washington, D.C. and requested a sit-down with Pres. Obama and began making public announcements about SFP4 and the rest of the plant, saying that Japan needed to accept outside help. Though there was a lot of resistance from both political parties, he got the ball rolling. He also met with people from the UN who were trying to get that leadership to create a core group of scientists, engineers and doctors from all over the world to go to Japan. Japan was publicly not interested in the offer. But, maybe they have accepted help after all. Since then, SFP4 suddenly gets priority and, as you've pointed out, so does Reactor 1. Wyden understood the timing – the increased protests in Japan, TEPCO's cold shutdown theory coming apart at the seams, the debris field beginning to wash ashore, sites like enenews getting info out to the public, US plants having issues. He took one theme – "TEPCO is out of its depth and that poses a danger to the world" and stayed on message. It was one more step towards legitimacy – an allegedly pronuke Senator saying time to rethink this. Btw, there are no longer any NPP's in Oregon.

  • islandboy9

    no rad readings because,1)people that check and report the readings in fukushima are in tokyo joining in the protests.2)japan is in the middle of it's rain season and winds flow through fukushima an out to sea nonstop from june to mid july, a week from now when shifts back to japan..3)when sfp4 caved within the building it didn't hit the ground as the world feared,so with a lid on top and previous fires it allows workers to remain onsite to demolish(6/26), the top frames and cover it and try to supply coolant. sorry about the wrong link if you can find Tepco livecam you will see thick smoke in sfp4 area. OH, YOU WILL GET THOSE HIGH RAD READINGS AFTER RAIN SEASON ENDS IN ABOUT A WEEK AND THE WINDS SHIFT BACK TO JAPAN11111

    • DrTom


      The general assessment is that you are wrong, but you aren't. There are no rad readings because TEPCO is pouring tons of boron in there, but that won't solve the problem. Nothing will.

      It was pretty obvious when the camera went off that the fuel had fallen through.

    • Radio VicFromOregon

      So, instead of saying that the pool has crumbled and fuel rods are laying exposed on the ground, the pool actually fell several floors intact and by pouring in water, it remains cool? That would be a blessing. Then we wouldn't need to worry about future earthquakes since the heavy water laden pool is already on the ground. It would also explain why there are no rad readings of a toppled fuel pool at ground level or atmospheric level. You had me worried there for a while. So, actually, things are better at SFP4.

      • flatsville

        Here is the original enenews article IB9 keeps referring to–

        I didn't think reading a blueprint (which clearly shows the top of the SPF4 water level just below the service floor and NOT immediately below the roof) was that difficult…apparently it is.

        If he is correct in this:

        >>>2)japan is in the middle of it's rain season and winds flow through fukushima an out to sea nonstop from june to mid july, a week from now when shifts back to japan…<<<

        Out to sea nonstop across the Pacific and beyond…Those readings would be all over the globe by now…so, where are they?

  • Radio VicFromOregon

    Yes, the boron is helping. In fact, to contain leaks, Arnie suggested that a deep trench that reaches below the groundwater level should be dug all the way around and below the entire plant and filled with boron. But, that is an expensive, though, effective solution, and not likely to be done. Now, ascribing reasons why cameras go on and off without a way to back up your guess leaves it just that – a guess. While i find them fascinating to speculate about, I personally don't go by camera images. They are open to everybodies interpretation and, sometimes, those interpretations have an agenda to mislead people for or against nuclear power. Misleading is never ok in my book. We need factual evidence so that we know what to do, what action to take, who to pressure, where to rally, where to evacuate, what not to eat. Painting this crisis with the broad brush of "total doom" makes it hard for people whose lives are a stake to make those meaningful, vital choices.
