    Maybe the MIRACLE is that SFP4 is still standing. Period.

      And to think of what's sitting there
      (taken from another link but good to revisit):
      • All these fuel rods are, astonishingly, exposed to the open air. They are not held inside any containment vessel.
      • The total number of spent fuel rods across all six reactors at the Fukushima Daiichi site is 11,421.
      • If reactor No. 4 suffers a structural failure, the release of radiation from the 1,535 spent fuel rods would make it virtually impossible for work to continue on the site, potentially resulting in an inability to halt a massive radiation release from all the other rods.
      • In all, the 11,421 fuel rods held at the Fukushima Daiichi facility contain roughly 336 million curies of “long-lived radioactivity.” Roughly 134 million curies of that is Cesium-137.
      • “Reactors that have been operating for decades, such as those at the Fukushima-Dai-Ichi site have generated some of the largest concentrations of radioactivity on the planet.” – Mr. Robert Alvarez, U.S. Dept. of Energy
      • This amount of Cesium-137 radioactivity held in the full collection of fuel rods at Fukushima is 85 times the amount released at Chernobyl.
      CLOSE TO THE EDGE IS RIGHT. :(

        • Reactor #4 contains 1,535 spent fuel rods which remain highly radioactive.
        • These fuel rods currently hold the potential to emit 37 million curies of radiation.
        • Those fuel rods are stored in a concrete pool located 100 feet above the ground, inside the structurally compromised reactor building, effectively making the pool open to the air.
        • The pool holding these fuel rods is “structurally damaged.”
        • “If an earthquake or other event were to cause this pool to drain this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.”

          Whoopie, I think you meant to say 'fuel assemblies.' There are far more fuel rods in SFP #4:

          Why Fukushima Is a Greater Disaster than Chernobyl and a Warning Sign for the US
          The radioactive inventory of all the irradiated nuclear fuel stored in spent fuel pools at Fukushima is far greater and even more problematic than the molten cores.

          “…As more information is made available, we now know that the Fukushima Dai-Ichi site is storing 10,833 spent fuel assemblies (SNF) containing roughly 327 million curies of long-lived radioactivity About 132 million curies is cesium-137 or nearly 85 times the amount estimated to have been released at Chernobyl….”

        11,421 fuel assemblies times 200 gives us 2,284,200 fuel rods.

    5 Kilometers is a very shallow earthquake. And only 19 miles east. There is no doubt the water was splashing around in all the pools.

    Vermont Yankee (what a patriotic sounding name) holds north of 3,000 spent fuel assemblies in its spent fuel pool (read FOOL POOL) …

    If this little swimming pool were dewatered by a stray tornado, say, or a small plane or any other of sixty million one-off ain't ever gonna happens, then the smoke and radioactive plume would find its way to the Quabbin Reservoir, metro Boston's drinking water supply, less than seventeen miles away, downwind, (most of the recharge watershed lies substantially closer than this) … and this counts for science? This counts for regulation? This counts for sound energy policy? This is in fact tempting the nuclear devil!

    NEWS FLASH: The Nuclearists have invented a new game … American Roulette. This is the one where the crazy guy (insert reactor operator of your choice) loads the gun with six bullets (it's a six shooter) and spins the chamber (for comic effect) and places the barrel of the gun against your and my temple and pulls the trigger …. BANG you're dead. Sound like fun? Coming to a nuclear "spent fool pool" near you! Stay tuned, and wash your feet.

  • workers today at reactor #4. strange the camera starts shaking about 3:20 or so. maybe not the same time as the earthquake tho
