Nuke report’s worst case: Tokyo exodus, Japan Times, Jan. 5, 2012:

[...] In interviews with the media, [Former Prime Minister Naoto] Kan said he was particularly scared in the first week of the crisis because he had to entertain the possibility of evacuating the capital, without elaborating further [...]

Worst-case Situation?

  • Compiled March 25
  • At the request of then Prime Minister Naoto Kan
  • Drawn up at the height of the crisis by the chief of the Japan Atomic Energy Commission
  • Alarming 20-page report was written up by commission Chairman Shunsuke Kondo
  • Kondo drafted the report after Kan asked him for a “worst-case situation”
  • Kondo emphasized that the scenario was based on extreme conditions and was not very realistic
  • The report uses the same evacuation protocols adopted during the 1986 Chernobyl accident
  • Areas 250 km away — including central Tokyo — could have been tainted by radiation and require the gov’t to assist those electing to voluntarily migrate away
  • Scenario is based on the assumption that another hydrogen explosion would have further damaged reactor 1, releasing more radioactive fallout into the environment and forcing the entire plant to evacuate
  • With no workers to control the situation, the cooling systems at reactors 1, 2 and 3 would be lost and the spent-fuel pool in reactor 4 would collapse as the rods melted through its concrete walls, the report said

    Well, let’s hope reactor 4 holds. There was just a 3 point and 4 point earthquake at Fukushima a few minutes ago.

    Could have? It has been contaminated. Who are we kidding here!!

    Yes we have all been dosed. I can’t wait to see the results of the following “Tokyo Electric Power Co. is to use an industrial endoscope to look inside the containment vessel of Fukushima Daiichi reactor 2 for the first time since the 2011 earthquake. The utility says the 33-foot long, 1/3-inch wide device will be deployed this month to measure temperatures and other parameters inside the reactor, including the condition of the pressure vessels and melted fuel.”

    One more Tsunami and you can say goodbye to the whole world.

    from what I know of the british Civil defence, during extreme nuclear situation drills in the cold war, you must remain in your county (similar to a state/prefecture). I know they used to simulate drills of nuclear attack and simulated people evacuating big cities to the country, but to maintain food protection the city evacuees had to be forcibly stopped by the military – in these drills – and they were only drills. So Sadly it isn’t a surprise that the big cities population are kept in place with a triple melt down fairly close by. in a cold logical way it would be an increased population struggle to have that many homeless in japan if everyone left tokyo.

    If the Prime Minister has been forced to order the evacuation of Tokyo, how would he have done that?

    1. “Everyone must leave, radiation levels are too high.”

    2. “Godzilla has been spotted in Tokyo Bay, we must flee.”

    3. “The Autumn Society is sponsoring a fall leaf tour for all Tokyo residents.”

    4. “The American invasion fleet is offshore and planning to attack Tokyo tomorrow.”

    Or….???

    Hmmn, not very realistic but based on 1986 Chernobyl evacuation standards? Is that “weasel wording” for the contamination isn’t as great as what the worst case scenario could be, or it is but we’re not telling you what the actual contamination levels are, therefore not realistic ….

    Dang, them weasels are hidin’ everywhere! Gots to watch out for them weasels!

      Or does it mean we’re just not using the Chernobyl evacuation standards here, despite the contamination levels? (Since we already know the contamination in many areas is much greater than that in some Ukranian evacuation zones post-Chernobyl).

        OK, looking like they mean collapse of SPF 4 and abandonment, etc. But we already know there were four meltdowns, probable loss of spent fuel at SPF #’s 3 and 4, and contamination in some areas was much higher (5X ?) that in some areas around Chernobyl. So I’ll argue the model wasn’t so “unrealistic” after all.

    REAL government nurtures and cares for its citizens. If Japan government had taken steps in March, they would be ready now to help evacuate. Now if the order is given..there are no prepared areas. Oh wait..there is..the SPECIAL new city the government built for a few..the rest of the citizens are on their own. Talk about ethnic cleansing..this is population cleansing.

    Not sure where to post this. Maybe some of you educated more in chemistry than I can answer this question:

    http://www.chemistryexplained.com/elements/A-C/Boron.html

    Where BORON NTRIDE is discussed (see below) has this substance been researched in terms of creating some sort of metallic alloy or ceramic that can be used to encapsulate the radioactive substances? Could it, for example, be added to steel or concrete? It’s highly resistant to heat, and very hard. Could it be used along with other boron compounds to neutralize and encapsulate the radiation?

    My guess is some brilliant lay person will come up with a solution for this. Maybe he or she could suggest this to some smart science type, and maybe, just maybe he or she will listen. Probably would take credit for it, but who cares, as long as something gets implemented? Sometimes it takes people who don’t work in the field to be able to “think outside the box” and come up with creative, inventive solutions.

    Credentials not necessarily needed by the brilliant! Steve Jobs was a great example!

    “Boron also forms important compounds with two other elements, carbon and nitrogen. Boron carbide (B 4 C) and boron nitride (BN) are important compounds because of their hardness. In fact, boron nitride may be the hardest substance known. Both compounds have very high melting points: 2,350°C (4,300°F) for boron carbide and more than 3,000°C (5,400°F) for boron nitride.

    These properties make boron carbide and boron nitride useful as abrasives and refractories. An abrasive is a powdery material used to grind or polish other materials. A refractory material is one that can withstand very high temperatures by reflecting heat. Refractory materials line ovens to maintain high temperatures.

  • WHERE IS FUKUSHIMA REACTOR 3? – It seems to be missing?

    Tell me if I am missing something here?

    It looks like the reactor and spent fuel pool are completely gone.

    Not for sure where it is now, do you mean now or after it aerosolized itself to death…
