Title: Demolition and Removal of Structures Damaged or Contaminated as a Result of the Fukushima Accident
Source: Tepco (IAEA International Experts’ Meeting on Decommissioning and Remediation after a Nuclear accident)
Author: Shunichi SUZUKI
Date: January 2013

Page 51: Fuel debris shown outside the suppression chamber

Identification of debris location

  • SA codes predicts that molten debris has fallen downward, out of RPV
  • No enough evidence at this moment to deny the existence of debris in recirculation pipes, suppression chamber or torus room
  • Attempts such as further visual inspections, SA code improvement and MUON technology are continuing

More from Tepco’s presentation:

  • Molten corium discussed on pages 56 and 57
  • Excerpt from summary: “Many unexpected situations are expected. Flexible program management will be necessary. Advices and counsels from the world community would be very much appreciated.”

  • Why Nukes and Humans should not mix on the Home Planet
    The real problem with nuclear is not so much the technology, its the cost to make it "safe enough" but then the stunning realization that if humans are involved that nuke can never be safe because humans are highly imperfect creatures.

    In human nature there will always be episodes of greed, denial, "hope", laziness, times when the operators personal life if way out of whack, substance abuse (like the Kewaunee worker who was busted pounding beers at lunch, in containment), economic hardship.

    Advice to TEPCO, keep them ALL SHUTDOWN, FOREVER.

        2 years ago when this might have helped, TEPCO and the JG were utterly against any outside assistance. Now when the dynaimic phase is over, they are starting to ask for advice and counsel.

        OK.

        Here's my advice: "All Women of childbearing age, , Children and Parents with minor children and single men under 35 and critical skills individuals ( Doctors, nurses, pilots, scientists, professors, teachers, cultural artisans)should be immediately evacuated from the Home islands to the US. Those not included should be drafted into cleanup battalions to remove high level debris from the reactors and SFPs, and to assist in the shutdown and clean up of all Nuclear stations in Japan. As evacuees age out they should be required to return and assist the stay behind or as we call them the Fukushima 50 Million. "

        A mass evacuation now is the only thing that may preserve enough life to assure japan can continue as a culture

    Core on the floor and out the door…OMG how can they even imply that demolition is an option? Where's the Chernobyl sarcophagus plan? These international profiteers are mentally ill and should have all their assets frozen.

    American Public Media's Marketplace featured a story on Fuku and our BWRs vents being too small…filters would be way too expensive according to Exelon CEO Genocidal Maniac…so the public will have to endure massive highly Hot steaM releases during a power outage.

    Thanks Big Men…hope your descendents grow those monstrous legs like the Chernobyl kids bedridden by the hands of uranium mining stakeholders.

    "Many unexpected situations are expected." Translation: we have no idea what to expect but want to sound like we have things under control, which we don't. :p

    UNEXPECTED..if you believe that, I have some swamp land to sell.
    There has been professionals yelling at the top of their lungs from day one.

    They ran out of excuses, so now they are calling it UNEXPECTED…

    Violation of public trust
    Violation against the environment
    Violation against the health of the people
    Violation in putting profits and corporations first
    Betrayal of preserve, protect and defend the people

  • Japan detects xenon 133 in air – Blames North Korea but could the source be a bit closer to home?

    Xenon-133 is released into the air not just by an atomic explosion but also from nuclear power plants and medical institutions.

      Hi arclight

      Wonder if North Korea knew they were handing Japan another excuse?

      WOW ..No more excuses Japan and all other Governments…The fact is, Nuclear Power Plants are too dangerous for our environment and for the health of the public. This plant is an on going catastrophic disaster to the world, it will/has reached far, and they know this.

    Where is the corium, TEPCO?
    Answer: "No enough evidence at this moment to deny the existence of debris in recirculation pipes, suppression chamber or torus room"
    All Reactor Building drawings in TEPCO's slide show have a heavy solid line at bottom of building, with no hint that corium may have gone China Syndrome on them.
    The public should demand slantwise core drilling under Unit1,2,&3 in order to reassure everyone that melt-through didn't exit the building structure.
    Most ENEnewsers believe that over 200 tons of nuclear fuel burned out the bottom of Building1,2,&3 about one week after 3/11/2011, and that 3 bus-sized ,blobs of corium are now located in the mudrock under the buildings.
    Here is a much better drawing of the most probable reality at Unit1,2,&3, that should have been included in this slide show:

    It's beyond the time to strip TEPCO of any leadership role in this project. It's time to form an international consortium founded on democratic principles, with mutually accepted financial responsibility, in order to complete the project asap.

    Transparency should be absolute, citizens around the world deserve a full daily situation report and nothing less.

      No. It had to have been long since "transparent" enough to THEM, that they were willfully, fatally, poisoning their own population. Someone "help" them to jail, please. Or invoke some long, time-honored Japanese tradition. They've had the indecency to kill OTHER people.

  • This is a cry for help. I hope the world is listening.

    1. “Advices and counsels from the world community would be very much appreciated.”

    – Reading between the lines, this says… "We need 'HELP!', the world is being destroyed.

    2. “Many unexpected situations are expected. Flexible program management will be necessary.”

    – Reading between the lines, this says… "We don't have a clue! What we do know is that the chit's going to hit the fan and this is going to be a real mess."

    Where's the jail time for TEPCO? They can have their choice of detention facility: Unit 1, 2 or 3. Oh, they might find the results "unexpected"? No one cares, you won't be missed, bye-bye.

    Even a glance at this report by a layman shows that it was not written NOW. It talks of what will be done by 2012, 2013. Insanely unrealistic plans like "fuel debris removal from Unit 4." They don't know better? I know better. You know better. I don't believe in the death penalty, but what happens when you've consigned millions of OTHERS to death? This makes Hitler look like a sideshow.

    We don't even understand how the world bought the "cold shutdown" hype in December 2011. At BEST, that would be temperature down within the containment vessels. But "meltdown" means, by definition, that the fuel is OUTSIDE the containment vessel, in an uncontrolled ongoing outlandishly hot state. The public is kept so ignorant and the explanations are so twisted, that there is no way any of their announcements even make sense, much less are true. So how about something REALLY unexpected for TEPCO and the Japanese government? — like mass arrests of THEM? Their jail time can be spent in a choice of reactors 1-4.
