Fukushima Nuclear Accident Update, International Atomic Energy Agency (IAEA), March 21, 2011 at 23:15 UTC:

Japanese authorities have also reported that water has been sprayed over the Common Spent Fuel Pool; this started on 21 March at 1:37 UTC. The IAEA is seeking further information on this development and will report further as updates are received from Japan.

The Common (Shared) Storage Pool

In addition to these individual pools, there is a larger common spent fuel pool that is used to store spent fuel from all 6 reactors once it has been out of the reactor for 19 months and has cooled down. It has a volume of 3,828 cubic meters (29m x 12m x11m deep) and currently has 6,375 spent fuel assemblies in it. It is located 50 meters west of Unit 4. Reports also say that this pool continues to have water supplies but its cooling system is not functional.

    Size of Nuclear Fuel Assemblies

    A single fuel assembly for a boiling water reactor (BWR) is approximately 14.5 feet high and weighs approximately 704 pounds.

    A single fuel assembly for a pressurized water reactor (PWR) is approximately 13 feet high and weighs approximately 1,450 pounds.

    The PWR fuel assembly weighs more because it contains *264 fuel tubes*, while the BWR fuel assembly contains 63.

    The very large COMMON SPENT FUEL POOL.
    All fuel rods were very likely exposed to the air while the electric was down for days.
    The circulating pumps for ALL reactors & fuel storage ponds had no cooling & circulation of water.

    Well………It is now looking like the fuel rods in the center of every bunch of fuel rods has over heated to the point where the melting will continue to a complete meltdown of every single fuel rod at Fukushima.

    Chernoybal was a tiny candle.

    Fukushima is a disaster rating of maybe 200 ?

    There is nothing that can be done to reduce the endless stream of increasing radioactive steam from all the fuel rods that are melting.
    Minature radioactive explosions are very likely with the core of each fuel pile unable to be cooled at all.
    Bad condition. And it may get much worse.

    I wish G E would tell us all, that there is no danger from nuclear meltdowns.
