  • “Minsk, 320 km away, would have been razed and Europe rendered uninhabitable. Tokyo, the world’s most populated city, is only 250 km from the Fukushima meltdowns.”

    Much biger pronlem then Chernobyl
    3 in meltdown, Fuel pools and a whole lot more fuel, and still poluting, plus that fuel storage that burned in March !

  • I am sure I posted an article about a month ago that plans to build this were canceled ! Should be in one of the weekly FORUM: Discussion Threads !

      Hi xdrfox, I think Tepco cancelled the wall towards the landside of the compound, but agreed to try to shield the ocean side. They said the main direction of the flow would be towards the sea, not inland…..

      TEPCO won’t build retaining wall to stop radioactive water seeping into ground water
      http://mdn.mainichi.jp/mdnnews/national/news/20111027p2a00m0na009000c.html

      “The utility, however, will construct an ocean-side retaining wall to prevent contaminated water from leaking into the sea, starting on Oct. 28.

      TEPCO had initially planned to build a land-side retaining wall (an underground dam) as well, thereby surrounding all four sides of the reactor buildings and turbine buildings of the No. 1 through No. 4 reactors at the plant, in order to prevent highly radioactive water from coming into contact with the ground water.

      However, the utility concluded that such a plan would be “ineffective” on the grounds that the ground water in the area flows only downward into the ocean as the area’s terrain is seaward-dipping and building a U-shaped retaining wall on the land side would make no point in preventing contaminated water from leaking into the ocean.
      The utility also said a land-side retaining wall would lower the ground water level around the reactor and turbine buildings, raising the risk of contaminated water leaking from those buildings. In addition, the utility said, the construction of such a wall would require the removal or relocation of existing facilities surrounding the buildings.”

      It is utterly ridiculus to believe that wall will stop the contaminated water from reaching the sea.
      Sure it may stop “groundwater”, but what about underground water.
      How far is it to sea level? That island is a fractured mess.
      The underground water that is below sea level ebbs and flows with the pressures of the tides of the ocean.
      It will go wherever the underground pressures send it.

      A fools folly at best. An idiots nightmare at its worst.

        They remind me of some CALTRANS workers out here in LaLa land. They lean on their shovels WHENEVER they think no one is watching. They work when they’re being scrutinized.
        Tepco is being scrutinized, obviously, huh?!

  • An explosion as this magnitude may well create a tsunami that would also take out the coast of other countries, RIGHT ?

      5 megatons will not incinerate tokyo but can kill every1 outside with radiation if winds blow in the big city direction.

      not even trains with 1000 cars can move enough people far enough, specially because its all electric driven and if such a kill cloud appears all other power plants will stop due to lack of people and themselves create a bigger cloud, fuck I didn’t buy the boat yet. well I’ll have to steal 1 in a marina near me… :P

    Good job Admin. Quite a list here.

    So if a melt through is pretty much a certainty when these accidents occur, shouldn’t we demand that reactors be built on platforms that cannot be penetrated by a melting core. Probably not possible, but then again, I never said I actually wanted the reactors built…

      “shouldn’t we demand that reactors be built on platforms that cannot be penetrated by a melting core”

      But that would cost plant operators money. Besides, I believe Arnie Gundersen has said that in the NRCs models of accidents that can occur, they assume no more that 1% fuel damage is likely to occur.

      Well, if I’m remembering that correctly, that model has obviously been proven 100% wrong by Fuku–it seems to me it calls into question all of the NRCs other models as well (i.e., their estimates of risk, the evacuation plans, etc.)

    My question every time I see that clip from The Battle of Chernobyl is why aren’t the Japanese taking this scenario seriously. Several sources have suggested that the reactor #1 fuel (at least) has probably melted down into the ground underneath. Why no effort to block, as the Soviets did?

    Moreover, the Soviets according to this clip had made preparations to evacuate people as far away as Kiev (which I believe was farther away from Cherno than Tokyo is from Fuku). The Japanese seem to be entirely ignoring the possibility of such a secondary explosion–but how much of Asia would be devastated by such a blast? And imagine how much fallout would result from it, considering all of the spent fuel on site and the fact that the fuel of all three reactors is probably out of its containment.

    I know,…idealistic of me,…but I think other Counties are about to ‘step in’. Just like my ‘stupid rat’ analogy,…the water is rising,…we ALL see ‘it’ now,….other County’s ‘accord of silence’ (nuclear),…is having a MELTDOWN!

    Like the kid who jumps off of the tracks at the last moment in a game of CHICKEN,….these surrounding Countries WILL FLINCH-IMO
