    Japans nuclear meltdown III

    Paradigm Intel: Japan meltdown.

    US officials warned of the rising risk of a catastrophic radiation leak from spent fuel rods.

    IAEA world’s nuclear watchdog, impotent in nuclear accident.

    In another sign of international frustration at the pace of updates from Japan, Yukiya Amano, director general of the International Atomic Energy Agency, said he would fly to Japan on Thursday to get first-hand information. Six days after first explosion at a Nuclear plant. Six days and 4 explosions later IAEA is expected to arrive.

    Problem with IAEA data: Based on a press release from the Japanese Chief Cabinet Secretary dated 16 March 2011, the IAEA can confirm the following information about human injuries or contamination at the Fukushima Daiichi nuclear power plant. Who got his info from the Utility running the 6 nuclear plants.

    Right now the IAEA has to wait for an invite to come into a country that has a nuclear accident. THAT ISN'T ACCEPTABLE, IN VIEW OF THE RISKS TO THE WORLD FROM

    No. 3 has experienced at least a partial fuel meltdown, and it contains nearly a quarter of a metric ton of plutonium.

    No. 3 reactor is the uranium-plutonium fuel, called MOX (for mixed oxides of uranium and plutonium), that was loaded into the reactor last year.

    Plutonium has a half-life of 24,000 years, warning that if it burns through a containment vessel, it could release vast amounts of radioactive steam wherever the molten material encounters ground water.

    However, with plutonium inside reactor No. 3, if it melts down or explodes, then even microscopic quantities of particulate will cause lung cancer in anyone who inhales it.

    Authorities have confirmed that radioactive iodine, which causes thyroid cancer, and cesium, which causes leukemia, have been detected in the air around Tokyo, in very low quantiles.

    Plutonium is weak emitter that registers low on radiation detectors, but it is an intensely radio-toxic material.

    Nuclear reactions starting
    By Wednesday morning Japan time, the BBC confirmed that a "criticality event" was being reported in the No. 4 fuel pond after it caught fire.

    "The explosion at the spent fuel pond at reactor No. 4 was a criticality explosion," Moglen asserted, "which means that the fuel in that pond has begun to interact on a nuclear level--that there was a nuclear chain reaction going on in the pond."

    A "criticality event" means that the melted fuel rods accumulated enough mass to exceed the "critical" stage and start a nuclear chain reaction similar to the controlled reaction in a normal reactor. Without a containment vessel, the nuclear reaction emits large amounts of radiation while potentially releasing radioactive particulate directly into the air.

    "The spent fuel ponds are even more dangerous than the inside of the reactors because the fuel pools are open to the air. At least there is a containment vessel around the reactor cores," said Moglen. "All six pools are in jeopardy, since they need to be constantly supplied with water to replace that which the fuel rods are constantly boiling off."

    A critical Nuclear chain reaction risk at Fukushima is not zero.
    It just isn't known what conditions could trigger this type of event.
    Our sources indicate the possibility of temps of 10,000 degrees
    in some possible circumstances.

    nuclear chain reaction occurs when one nuclear reaction causes an average of one or more nuclear reactions, thus leading to a self-propagating number of these reactions. 

    Dumping water on the reactors from 80 yrds in the sky is a desperate
    attempt to cool the events, and about as effective as pissing on a house fire.

    They do have a chance of pulling a rabbit out of the hat on this one,
    if they can get electric restored and re-activate some cooling system.

    The site will end with a huge concrete cap and a possible death zone
    around it, and cost Billions in clean up. Thats the best case.

    Worst case, and a very remote possibility involves a mushroom cloud.

    This is very serious with many unknown factors. US has its best
    nuclear minds and computers on it but its virgin Territory.
    But US was invited late in the game by Japan.
    History will tell if it was too late.

    And why I think US set up a bigger danger Zone.
    Because of the risk of a fallout situation.

    Engineers at Japan's stricken Fukushima nuclear power plant have successfully 
    connected a power line to reactor 2, the UN's nuclear watchdog reports.
    Professional speculation Core broke.
    Restoring power should enable engineers to restart the pumps which send coolant over the reactor.
    If salt water didn't damage pumps....
    sources say pressure down, not sure if pumps working,
    ONE down 5 to GO.
    Japan's reactors nothing wrong with them, passed 9.0
    earthquake, failure lies in not protecting backup cooling
    systems from expected Tsunami.
