    TEPCO contaminates Japan & entire world with MOX. And all they have to say is the stainless steel liner of SFP3 may be TORN? Pardon me, but BFHD.

  • eatliesndie eatliesndie

    What a bunch of wackers!

  • norbu norbu

    Are they using all 10 of there workers on this one?

  • weeman

    The original stainless steel liner has been bombarded by neutrons and has become brittle, funny that the water in the area they are fixing seems to be clearer than the rest of the pool anybody any ideas.

    • weeman

      I studied the photos and came up with a reason for half the SFP is cloudy and the area with the reactor appears clearer, the explosion was in the reactor therefore all the debris in that area was blown out and came down on the other parts of SFP ? Anybody got input, interesting .

      • HoTaters HoTaters

        Concrete dust in SFP. If there is water circulation, it keeps stirring up the concrete slurry at the bottom of the tank.

    • Sirius

      And add the fact that they poured tons of salt water on that brittled liner…

  • Solar is 3 cents per kWH.

    Why are we even considering nuke at all? It has failed time and again. Kill Nuke


  • snowwy snowwy

    getting a touch confused here now.

    not so long ago i read that no worker can even get close to unit 3

    is this true or not true?

    is this an optical illusion or does the SFP3 appear to be located much lower in the building or what is left of it. last time i looked there were only 2 levels left of building #3. this really and seriously confuses me.

    • snowwy snowwy

      another bit that confuses me it that building #3 had a very large explosion… how did SFP3 miraculously survive it with just one crack? meanwhile fuel was found over a mile away … so what exactly blew up, how much of it, what is the state of SFP and reactor #3?

      when shall i start to believe in the easter bunny again? because i might as well with all the fairy tales that surround Fukushima Daiichi?

      • eatliesndie eatliesndie

        These are verrry good questions…..

      • AGreenRoad AGreenRoad

        Santa and the Easter Bunny live inside #3, which miraculously survived both the explosion and the meltdown.

        All of the spent fuel and the fresh fuel in the reactor is STILL THERE, thanks be to God, Santa and the Easter Bunny.

        Now TEPCO just has to figure out how to get Santa and the Easter Bunny to deliver these delicious 'leftover's to little kids, so that they do not have to deal with it.

        They seem to be doing a pretty good job delivering lethal doses to their own kids, so we think the plan is to get Santa to deliver radioactive fuel rods to children all around the world.

        The Easter bunny will hide spent fuel rod bits inside of Easter eggs.

        Problem solved.

        Next PR release, coming in January of 2013;

        No more radiation to be found in #3. No fuel rods left in spent fuel pool or reactor #3. Easter Bunny and Santa took them all away.

        • AGreenRoad AGreenRoad

          Either that, or they may start the planning process to sacrifice virgins and throw them into whatever is left of reactor and SPF#3, to get rid of the radiation and melted coriums that way.

      • m a x l i

        @snowwy, wait two or three more years, and there NEVER WAS an explosion. If you think otherwise, it will be only your – you said it – confusion.

    • HoTaters HoTaters

      Yes, snowwy, you are correct. I thought (and recent reports said) no one had gotten close to Unit 3. Maybe they mean the reactor itself? But you are correct, they're working there, now.

      There are robots doing some of the work onsite. Am not sure how close humans are actually getting to the SFP and the reactor itself.

      Good question, yes, it' confusing.

      • HoTaters HoTaters

        Cranes are doing some of the work, too. That would extend the "reach" of any work being done w/o requiring a human being to get too close.

        Perhaps #3 has cooled down since the accident first happened. Can anyone comment? It still seems to be very radioactively "hot" based on recent reports ….

  • Heart of the Rose Heart of the Rose

    So… is this a cool time to talk about..the Common Spent Fuel Pool?

    [Express] “Common usage pool may be more heated than SFP of reactor3″


    • HoTaters HoTaters

      Heart, it's always a good time to discuss the fate of the common SFP. If the plant were to become further damaged, the common spent fuel pool could rapidly become the "issue du jour." Some of us were saying here early on (a year or so ago) the fate of the common spent fuel pool is a really, really important thing to consider.

      Would any of you "old timers" care to weigh in on this one?

  • PhilipUpNorth PhilipUpNorth

    Yes, Heart. "Common spent fuel pool has 6,375 assemblies of spent fuel, is located in only 50m west of reactor4." From Fukushima Diary.
    I get the feeling that TEPCO is dragging its feet to let the spent fuel in the Common SFP cool to the point where it can go into dry storage. Did you catch this article from Simply Info on this topic?
    TEPCO plans a storage facility to contain 240 dry casks. This is spent fuel from SFP1,2,3,4,5,&6, plus what is currently in the Common SFP. I believe the cost of the steel casks would come down with a redesign and from mass production. The problem is that current dry casks are not designed for permanent storage. Better to build steel and concrete storage facilities, using Markww's ingredient list for the borated concrete. Spent fuel goes into mobile steel containers, that are lowered into each SFP, and loaded with spent fuel assemblies using a customized Mobile Marine Crane (described by me in another thread today.). These are hauled by truck to the storage facility, and lowered into cells built of borated concrete, like a honeycomb, in the large storage facility. Once the storage facility is filled with 240 steel casks, the top is sealed with another 10' layer of reinforced concrete. Finally, a membrane roof is put on top to keep weather out, and to seal any leaks in. Done deal. Nice solution. Permanent storage on site. Probably cheaper than TEPCO's plan for steel cask storage.

      Great work, great thinking, guys. Now the only thing IMHO one would need to add is a structure on which to place them which will absorb the shock from earthquakes or other earth movement. Think the roller or shock systems on which skyscrapers in the Pacific Northwest are built.

      It might be a good idea to think about what kind of low maintenance or no maintenance safety features could be added so that if, for some reason, people aren't able to work on these things, they'll still be in (more or less) safe "permanent" storage.

      And add a pictorial instruction manual to tell posterity what's there, why it's there, and what to do/not to do with it.

    • HoTaters HoTaters

      Based on the report I read today re: the Rokkasho Plant, Tepco is pushing to have Rokkasho built so they can store the fuel from Fukushima Daichi there.

      The Tepclowns are very hard to nail down, when it comes to factoids.

  • ForwardAssist ForwardAssist

    I think burying the casks would be ill advised. Better to store them inside a dry warehouse, either above or below ground, where you can monitor for leakage, perform visual inspections, and keep them dry.

    Either bolt the casks to the floor, or rest them horizontaly in cradles so there is no way they can shift.
