Japan Newspaper: Unit 3 steel beams were bent inward by explosion, Unit 4’s bent outward — Some hang in No. 3 fuel pool 12 feet deep

Title: Removal of steel members started at Fukushima I unit 3

Caption: Columns and beams of the unit 3 building are bent inward


Unit 3 […] is slated to complete debris removal by around next summer.

What is different from unit 4, which has completed debris removal, is that columns and beams of unit 3 are bent inward. Because many of the columns and beams of unit 4 were bent outward, it was possible to handle them remotely with a large crane. A platform will be constructed around the unit 3 building at the height of the fifth floor, and debris will be removed with heavy machines deployed on the platform.

Some steel members are submerged in the unit 3 pool as deep as about 3.5 meters [~12 feet]. Although they do not interfere with the fuel at present because the top of the fuel is at about 8 meters deep [~26 feet], TEPCO intends to pull them out while taking care not to damage the fuel.

  • A quick review shows some very disturbing trends.

    An obvious uptrend in radiation is spreading across the country, with some areas seeing scary high levels. Something happened around Sept 17th.

    Rule of thumb is that exposure to 100 CPM clicks per minute for a year results in a real risk of cancer, 500 CPM for 90 days is a real risk.

    Many places are now up over 100,

    25 is "normal" we just don't get that much lower. And back in the day, before Fuku, 50% to 66% of us got cancer, what will the new normal be.

    Basic protective measures, air filters, anti-oxidants. Do them now if you are not on track.

      I'm with you!
      The younger you are the more this will affect you and especially your children and of course their offspring!

      For a glimpse of what is coming look at those that were exposed during the War to radiation during the Bombing or testing of atomic weapons.

      Paul Langley's Nuclear History is THE place to go for well researched information on all thins nuclear and lately he has been post great info on BOTH survivor health studies and the exact chronological of the Fukushima meltdown Before the Tsunami struck!
      Here is one link to get you "HOOKED":

    Look at Fukushima Daiichi on Google maps and you can see the same with the beams of the buildings 3 and 4.

    Off Topic but please post….

    It would be great to get a little support on U2.com. They're currently allowing me to post info on their front Page. (Message board and Pictures)So it would be great to make Hay while the Sun Shines!!!

    Beams bent inward…would that be heat from inside the pool partially melting them?

    Time Is Short said: "There are things going on at that site that no physicist has ever dreamed of."
    An implosion would suck beams inward.
    An explosion would bend beams outward.
    I have been rethinking what happened at Unit3. First, SFP3 looks just a bit too tidy to have been the source for the explosion. The racks are not twisted and tilted, as you would expect from fuel bundles exploding nearby. The steel liner of SFP3 seems intact, and the concrete rubble seems not to have been produced inside SFP3, but instead dropped into the pool as the debris rained back down on the building. At the beginning of the explosion, I see flame emerging sideways out of the SFP area. http://iangoddard.com/fukushima01.html. Then the mushroom cloud takes off straight upwards. Reactor3 was probably not the source, since an explosion of this magnitude would have blown the reactor and containment lid and concrete plug right out of the building. Which would have punched a hole in the roof beams. Which did not occur. Just thinking out loud here. It's not that we have discovered the source of the explosion at Fuku3, it's just that SFP3 doesn't seem to have been the source for the explosion at Building3. The problem that I have with the ongoing cleanup is the destruction of evidence for what actually happened in the Unit3 explosion. Never finding out what happened here is simply unacceptable.

    Here is a link to the explosion at Unit3, with sound, including a slow motion with sound.

    Special (Official) Report on Fukushima Daiichi disaster:
    Cut away drawings of Unit3, along with discussion eliminating Reactor3 as the source for the explosion:
    Prior ENEnews thread discussing possible sources for the explosion that destroyed Unit3:
    The explosion did not come from Reactor3. The concrete plug, reactor lid, and containment lid all remain in place. SFP3 seemed like a good bet, but fuel assemblies look intact, racks aren't twisted or destroyed as you would expect them to be if a large explosion had occurred inside the pool. Any thoughts?

      Everyone assumes that because we can see some intact fuel rods under the rubble in Unit3 SFP, that means the SFP can't have been the origin of the vertical explosion jet.

      That is not the case. The upward jet was from the SFP (proven by the roof damage) but it wasn't from a chemical explosion. It was mostly a violent expansion of water to steam due to neutron bursts from three rapidly sequential prompt criticalities in the SFP.
      The fuel rods are vertical structures. The water flash-boiling around them can only expand upwards due to the SFP walls. So the water/steam moved upwards between the rods, doing little if any damage to them. The roof on the other hand, was in the way (and already pulverized and moving upwards due to the initial H explosion.)

      I'm guessing the water level in the SFP at the time was very low, with the tops of the rods partially exposed. Maybe it had merely boiled low, or maybe much of the water had drained down into the breached reactor containment vessel. Some of the more active rods in the SFP may have burned top ends; hence the fuel pellets that were blown out of the pool in the steam explosion. But most rods are still there, albeit perhaps distorted. It's impossible to really say from TEPCOs very limited SFP video releases.

      What is certain: the high velocity jet came from SFP3, and there were three sharp bangs. Only one possible scenario could cause that. http://everist.org/archives/Fukushima/20120430_Message_of_Fuku3.htm

    Thanks PUN, news footage recorded three distinct blasts in rapid sequence. The TEPKILL footage is only showing a fraction of the SFP, and the roof beams are missing above the SFP, not the reactor vessel. My related question is why does the surface of the SFP look so badly pixelated in this pic from last week? TEPKILL really need to get a better photoshopper to work on their coverups and deceptions…

      I guess I'll have to make the point this way:

      Unit3 explosion did not originate in SFP3.

      Unit3 explosion did not originate in Reactor3.

      What caused Unit3 to explode?

      TEP.gov is right now removing the evidence of what caused the explosion of Unit3.

      The world is listening to speeches at the UN by world leaders.
      America is listening to speeches by Obama and Romney today.
      Is nobody even curious about what happened at Unit3? Guess not… So it goes.

      • JustmeAlso

        Phillip, many people do want to know what happened. For me what counts most is that it was/is possible to happen. So much for nuke safety, hey?

        I have found three vids from Goddardjournal about unit3.

        Just the fact that the NRC and IAEA eggheads are so silent on what created the massive blast at Unit 3 speaks volumes to me. They know what happened and it must reflect unfavorably on the entire industry. Thus the stone cold silence about what ignited the supersonic blast.

        They lied about the three meltdowns for months because they didn't want to spook Tokyo citizens in the first critical weeks. They will certainly lie about any thing they desire because after all…they are Big Brother. Citizens are just carbon forms they buy, sell, trade, and kill every day. Sounds harsh…because it's true.
