    Damage to rack? What is that supposed to mean? Where are the thousands of fuel assemblies? I don’t see the fuel. The fuel is gone. Adios fuel. Fuel went bye bye. No fuel assemblies= no fuel rods= no fuel. How did they get this sfp to hold water?

        Oh well then, you can see where they definatively declare the pool perfectly intact.

        The SFP3 shown in that video is definitely not destroyed. Destroyed pools are not full of water.

        That pool has lots of concrete and twisted metal that fell into it when the rest of the plant was destroyed, but the pool is intact.

          yes you have made yourself clear, it is just without supporting evidence it is impossible to believe you. Thanks for repeating though.

            The evidence is in plain sight in the video.

            By definiion the pool is not destroyed if there’s water in it.

            I’ll simplify the process for you….

            1. Can you see the water in the pool?

            If yes, the pool is not destroyed

            If no, then the pool might be destroyed, or you might be an [REMOVED].

            2. Can you see twisted rebar and broken concrete?

            If yes, it’s junk that fell into the pool
            If no, then the pool might be fine or you might be an [REMOVED]

            3. If stuff fell into the pool and the pool still holds water do you think he pool is destroyed?
            If yes, you are an idiot
            If no, the pool is not destroyed

              thanks James, we have been through this before. and I have already stated that I will not continue this discussion as clearly it is impossible to engage in a meainingful dialogue without your resorting to any number of ridiculous assertions.

              With respect to a camera being in water. First off it is my understand that contineoues flows of water into whats left of various levels of containment is ongoing resulting in the huge dumps of radioactive water into the ocean. Second, of all the video shot none show any nuclear fuel bundles. Of the couple vids that do show one or two bundles they show them as isolated one offs and only expose the bundle handle. And as I have repeatedly stated, to any discerning mind that is not evidence of anything definitive. In fact, based on such evidence it would suggest precisely the opposite, that the pool has indeed been disrupted by multiple explosions.

              Finally, my original comment was based on the fact that in this post SFP 4 shows, definetively without a doubt a fuel pool which ise easily compared against specs (such as Anee has provided). Its clear what we are looking at is part of a fuel pool at reactor 4. It is not clear what the status of the entire pool is, but at least we are able to make some proper observations.

              The point I have made all along is no such evidence exists for three. The official narrative is that it is intact. My opinion is such that if, in fact, the narrative were true they would have been able to provide the evidence they base the statement on. Which they have not. My issues has everything to do with the official version of events and status of the pool and nothing to do with you as I have dismissed you a long time ago as a crackpot. But do continue raging on if it brings you some sort of perverse satisfaction.

                Well Kevin, the one thing we can agree on is that I believe the pool has indeed been disrupted by multiple explosions – as evidenced by the piles of rubble that fell into it.

                In fact I think it’s safe to say that everything for hundreds, even thousands of miles has been disrupted by multiple explosions.

                Now if you are waiting for me to produce pretty pictures like the ones in the presentation above showing the fuel racks, well then I think we can also agree that’s not going to happen, because there’s tons of roof material all over whatever fuel is in the pool, and unlike the misinformationalists, I don’t want to bother photoshopping something that’s not true.

                So your point is apparently that the spent fuel is not in there, because you cannot see it through the rubble and because I cannot produce a picture of the fuel through the rubble then saying I believe the fuel is still in there, even though you admit the official record agrees with me, is a ridiculous assertion.

                Got it.

                  This will be my last go round with you, I promise.

                  I have only asked you to provide material to back up your statements. Anyhing at all will do, however you refuse to do so, claim your knowledge of the circumstance supercedes that of your citics and the onus is on them to prove you wrong. This is an odd track of reasoning, as it is you that is making unsubstantiated claims that to your mind are “100%” accurate, and the rest of us are simply looking for evidence that supports the claims you make and most have provided a myriad of data that suggests your wrong.

                  That said, I also find it odd that you hold up the official story ( as agreeing with you – lol – dude they dont even know you are or care) however you spend your days on here attacking the offical narrative and unearthing any number of points ( real or fictitous) as evidence that the officials are undertaking a devious misinformation campaign. So how on earth can you hold up there material as evidence of your outrageous claims? You cannot have it both ways James. They are either out to fool with misinformation or they are not, and it serves you poorly to hold up their data when it serves your perverted purposes yet dismiss the rest.

                  The only piece you have referred me to was the INPO report, which was a ridiculous, self serving load of complete and utter rubbish devised by the minds of TEPCO and IAEA in what to me is a criminal cover up. None of the material therein supports anything you say accept the hollow assertion that the sFP 3 is intact, but much like you they provide no evidence. Like how they continue to cling to the Hydrogen explosion theory and any number of other points of disinformation.

                  Finally in your last rebuttle you put words in my mouth, suggest things I do not state and once again muddy the waters with a bunch of unfounded nonsense.

                  My issue is really very simple. There is no evidence that supports the official version of the story that the feul pool is intact. Period.

                    Analysis of this video of #3

                    So chemfood, that video shows all the same pictures I used to analyze what happened at reactor 3.

                    The person that made it doesn’t realize all the details, or has simplified it in order to make a point.

                    Let me point a few things out to you:

                    Stop the video at exactly 2:05. This is a good overhead view of #3 about two weeks after the explosion.

                    Blow it up to full screen. Notice first the lattice roof structure which held up the reinforced concrete roof. The concrete is gone and the lattice is draped back down over the wreckage moved a few feet south and a bit askew.

                    Second notice the center joint of the roof sctructure – which is the “star” shaped one near the center of the building (originally was the exact center of the building). In reactors #2, 3 and 4 buildings the reactor itself was positioned a bit off center – which in this shot would be a little to the bottom and left of the center joint. Notice the roof structure has a big hole where the beams are rounded to the bottom and to the left of the of the center joint – more on that later.

                    Notice to the left of this area is the #3 fuel pool, intact, with green water in it and a bit of steam over it. This is indeed the fuel pool that the video referenced above was taken in. At this point they haven’t been adding water to it, and it is heating up – as evidenced by the steam. Amazingly the pool is intact. Everything on the whole site is covered with debris – a lot of crumpled concrete and rebar from the roof – and a lot of that dropped into the pool.

                    They haven’t got a water line on that pool yet because there was hot nuclear material that fell down between #3 and #4 and they couldn’t go in there – eventually they buried it and brought a snorkel in and added cool water to the pool. the snorkel is how they got the camera into the pool.

                    Ok now advance the video to 5:40. Stop it and blow it up to full-screen.

                    This is a different view of the same wreckage. Instead of looking from east to west, you are now looking south to north. to orient yourself find the center “star” beam the roof wreckage – pretty easy to spot.

                    Notice the green water filled fuel pool is still there just on the other side of the south wall, and to the right of the center of the building. The reactor containment is just on the other side of this pool – in fact there is a door that connects the two, that must still be intact, otherwise the pool wouldn’t hold water.

                    Also note the level of the top of the pool is almost up to the level that used to be the reactor floor. Note exactly how high the south wall of the building is in this shot, and that the wall is relatively unscathed below where it’s been blown off.

                    Now notice the very prominent “circle” of roof wreckage that I talked about in the previous note. This circle is a perfectly round hole in the roof beams, which did not exist before the explosion. There were no bent beams in the roof, only straight ones.

                    This circle of beams, which when you compare the two shots I’ve just showed you, you realize is, not over the spent fuel pool, but is exactly over the center of the nuclear reactor, and is exactly the diameter of the reactor cap – is proof in my mind of two things: First that the reactor cap at least, if not the whole reactor ejected in the explosion on March 14th. Second, this photo proves that the explosion did not occur in the spent fuel pool, which is intact, but in the core itself. This shot is literally proof the MOX blew.

                    Let me know if you see these things.

                    Proof the fuel pool fell a few weeks ago

                    Now, last step. Take note of the height of the south wall of Reactor 3 – which contains the spent fuel pool just on the other side of it.

                    Take a good look and use some references to determine how high the wall remains – which is almost up to where the reactor floor was prior to the explosion.

                    Now go look at the latest live TBS/JNN webcam view and compare what the same wall’s height is today.

                    You will immediately understand that the wall is quite a bit lower today than it was back in March when the pictures from this video was taken. You will also realize that, since the fuel pool is just on the other side of this wall – it has collapsed.

                    Ironclad proof that the #3 fuel pool was intact after the explosion and is down now.

                    Reactor # 4 was in a refueling outage so the rpv head and other assemblies would be visible. Reactor # 3 was in normal operation so the Reactor Vessel Head was in place, and thick concrete shield plugs were on top of the head. In normal operation one can walk over the top of the reactor on the 4th floor of the building and not even know what is right under their feet, and their is enough shielding from the concrete that the dose rate is close to normal background readings.
                    Too many non stories floated around by people who do not know the facts and that obscures the real dangers and issues.

                      Are you disputing what I say or the video narrative – which I said was either too simplified or naiive.

                      you are correct that the reactor 4 head was off and the reactor 3 head was on before the explosion.

                      However, my story of how the explosion occured is still valid. The containment cap at least, if not the entire reactor did indeed burst through the roof in the explosion.

                      The spent fuel pool was not destroyed in the explosion, but has fallen down now.

                      If you follow my instructions above and disagree with me, then I’d like to hear your opinion on which part you disagree with.

                      I was mostly commenting on the video narrative, as I did not see all your comments.Did the reactor pressure vessel head blow off the top, or is that even possible? Very doubtful it would eject intact just from my experiences seeing it installed and removed many times. It would have to go through many feet of concrete plugs above it, unless it was in a refueling mode and then the head would be removed also. Could a “nuclear explosion” blow everything straight up in a circular pattern-maybe.But the reactor head would be dust.

                      Could we have complete structural failure in any of the fuel pools? Only if the vast majority of fuel was in some configuration still was covered by water. Otherwise dose rates would be so high no work would be possible on site at all and releases would be so massive that their would be no way to hide the truth.

                  • Look at the roof of the adjacent building. It has a neat ROUND hole in it. It is about the size and shape of a reactor core cover.

                    Want to bet there is a yellow dome sitting at the bottom of that hole?

                    What happened to the spent fuel pool(s) sitting on top of this building and near the reactor core? I do not see those either…

                      Actually I recall the hole being more of an octagon shape – which is exactly the shape of the concrete plug above the cap.

                      Regardless I’m pretty sure something about the diameter of the cap blasted through the roof, and something pretty big came back down into the turbine building roof.

    If you search around a bit for Professor Downar, you find some interesting industrial connections that seem far removed from academia.

    Here is one possible starting point:

    Changes to R4 structure, may make all the discussion on fuel pool OBE. What would be invaluable is a CURRENT look at all the reactors..and into the fuel pools. The old videos and photos probably are only good for historical uses (or histerical usses). The AS IS is probably a lot different now. Wonder if anyone was trying to BURN up the nuclear fuel..in a fire or such..(“worklight? anyone”). That would be make more sense for a “filter” needing to be changed out for Reactor3 area. The TEPCO announcement is confusing. So workers rest a few days, they stop cooling the location, before replacing filter..huh? Just sounds a little unusual. Of course..no money..could the the factor.

    Wonder what happens when workers go home –and what they tell family. If I was TEPCO.I would not want any gossip to happen..and you know its going to occur. They probably need to keep those workers underwraps for a long time.or at least until they get the public informed of the full extent of the disaster(and officals can get out of “Dodge”).

    …so far..Party line is “Everything is fine, move back, COLD SHUTDOWN..etc etc.” A few workers are probably not going to stay quiet..especially if any are sick….
