Title: TEPCO investigates Fukushima plant fuel pool
Source: NHK
Date: Thursday, February 09, 2012 17:57 +0900 (JST)

[...] Tepco put a remote-controlled underwater camera inside the storage pool for Reactor Number 4 on Thursday [...]

[T]he reactor had 1,535 spent fuel rods stored in a pool above the reactor — more than any of the 3 other reactors. The temperatures in the pool rose steeply in March, raising fears that a partial meltdown might have occurred.

A hydrogen explosion blew the roof off the reactor building, sending debris falling inside the pool, and making it very difficult to look inside the storage pool.

    This is from May 8, 2011, doesn’t look like partial meltdown…. should be boiling?
    So, what is wrong: I guess, the Video. Just a guess, but I already guessed this last May. I believe the video was taken in another SFP, maybe 5 or 6.

    So, after approximately 11 months of observing the spent fuel pool of #4, when will they get around to reporting on what the camera is recording? Maybe on the anniversary of the major event.

    If you have not seen Akira Kurosawa’s film “Dreams,” see it! Made in 1990 it portrays the meltdown of six nuclear reactors in Japan.

      Dreams, a truly unforgettable film. I read somewhere that Kurosawa considered it his personal masterpiece. The nuclear piece was one of three “nightmares” among the dreams. A couple others are startlingly beautiful (the film consists of 6 or 8, i forget which, unrelated short films).

    No Sir, they won’t because they can’t. TRUTH is something like the lawof gravity, everybody can prove it on his/her own, but the Japanese officials can’t do that, if some authority says, an apple will fly up into the universe when dropped, they will repeat until they believe. The perceiving of truth is powerfully suppressed and creates the demons in Akira Kurosawas Dreams, which are gathered around the radioactive pools and cannot find their homes. This is the fate of the recent Japanese authorities. Sad, so sad.

    “The reactor was off line at the time of the accident on March 11th and no active fuel was inside the reactor.”

    it does not say THERE IS NO fuel in the reactor does it? does it mean its fully loaded and ready to go but has not ever had the control rods removed from this batch of fuel? (thus activating it) wtf?

    they admitted that it was fully

      I’ve never seen them admit that. Every document I’ve seen says 0 assemblies in the reactor, 1535 in the pool.

      • There have been several different stories that have come out. I have only seen technical documents stating all fuel assemblies were in the pool. That said, numerous officials from Tepco and the nuclear fraternity have made conflicting, incorrect, intentionally vague or otherwise misleading statements that confuse the public (intentionally, no doubt).
        I wish that I COULD just take Tepco statements, video, and data at face value. I hope that the radioactive inventory of sfp4 is indeed intact and stably cooled in a structurally sound building. Unfortunately, history shows the nuclear industry to have been and continue to be dishonest about their failings, to be overly confident in their power to control what they unleash upon the world, and to see the public as unworthy of the truth.

    Drip drip drip. TEPCO keeps slowing leaking out the information! Last year, the public would have mass panic to think they might get 1 mSv/h of radiation, or even a drop of cesium. Now its fine to have 10 mSv/h for school children to walk thru, 200 mSv a year..and okay to eat all the radioactive food products. Cesium, just smile and be happy.We’ve come a long long way in 12 months to accept being contaminated at high levels!

    Birth defects? no problem, just make them “go away”.

  • I postst 2 links somewhere on threads a few days ago with a video Japanese news broadcast saying there was another melt in 4 SFP in Nov.19 also !

    If a partial meltdown occurred inside the Spent Fuel Pool, what kind of consequences would that have? ………brains here?
    Or did they pour these trillions of liters of water on the meltdown , which would create a huge radioactive steam-soup?
    Arrrr I hate that kind of information politics. At least, all the nuclear scientists have been working on the Cernobyl incident, but zero scientific information comes from the nuclear scientists from Japan??? As if they didn’t know. What leads me to the only logical solution: the situation is worse than anyone can imagine, so it doesn’t matter what the *t*e*p*c*o boys say or do.

      I think we all knew that a partial meltdown occurred somewhere in #4, otherwise there wouldn’t have been any hydrogen to blow it up with.

      I can understand why a partial meltdown a year ago is important to anybody i’m much more concerned about the meltdown that occurred in that pool 3 days ago.

      The hottest fuel would melt first (ie that recently removed from reactor). the oldest fuel probably wouldn’t melt at all if it was far away from the major heat source. The US has recently done multiple studies on this but the results are top secret. There is some older public pool fire US research though that covers partial melt scenarios.

    Don’t forget everybody, TEPCO already stated that info would be released ONLY when THEY think the public is ready to handle the info!

      That indicates to me that the situation is far worse than we know. Just like Ben Bernanke said that he wasn’t going to release any info about which banks were in trouble because it might cause a panic.

      Duh! Anytime some government official says that they can’t give certain information because it might cause a panic, that info alone should cause one to panic! They are basically saying, “You should be panicking, but we can’t tell you why.”
