    how would one drop of mercury paralyze the kodak plant?

    Not doubting, just ignorant in these matters and truly interested.

    I assume they have no mercury thermometers inside Kodak Park?

    Bruce;

    Mercury is a powerful fogging agent that has a reasonable propensity to form vapor. It spreads via air as the vapor and fogs film. So, our mandate is to contain any mercury spill.

    Sandholm,

    You are the one who said it was a minor incident! That is part of what I was arguing against. Now you argue that it was not, as if that is what you have been arguing all along. What you said is:

    As for the facts regarding the details of the incident, they have not been presented incorrectly by either of us, so you should not say that the discussion "went away from facts to values/believes," as if I was stating a bunch of crap personal opinions. It is the reason that the event was not catastrophic that we disagree on. The facts in this area are that despite the operators sitting around with their thumbs up their butts for over half a day when they should have realized what was going on, the accident was eventually kept from going out of hand both by them, and by the engineering of that plant. It was a situation that could have been catastrophic if not for these things. And it would have been in a design like Chernobyl, and many other poorly designed plants. Prudent engineering and timely human intervention in a crisis simply and decidedly do not qualify as "pure luck."

    For anyone seeking information:

    - MEXT (Japanese Ministry of Education, Culture, Sports, Science and Technology) radioactivity readings

    - CNIC
    (Citizens Nuclear Information Centre)


    - Plume models (where is the stuff going?) by ZAMG (Austrian weather institute)

    - MEXT and TEPCO readings of radioactivity and reactor status (pressure etc.), as time lined graphs (only in Japanese, but live Google Translate on the page does a surprising good job)

    - Wikipedia about Fukushima plant

    - Scientific article about decay heat from spent fuel

    Even after 3 months in the spent fuel pool, 1 ton of spent fuel of a light water reactor fuel still may give something like 50kW. That is 5 MW of cooling needed for 100 ton of spent fuel...

    - Summary of "criticality accidents" report by Los Alamos National Labarotory

    Two sites with breaking news links:
    - http://www.breakingnews.com/filter/f...-prefecture-jp
    - http://newsblogged.com/fukushima-nuc...l-time-updates

    Site with potentially useful links:

    Photo's and videos below are from Japan News website:

    - Video Released Analyzing Spent Fuel Rod Pool of Unit 4 at Fukushima Nuclear Plant
    - TEPCO Releases New Photos of Fukushima Nuclear Plant Unit 4 – Pictures
    - TEPCO Releases New Photos of Fukushima Nuclear Plant Units 1 and 3 – Pictures
    - Fukushima Spent Fuel Rod Pool Unit 3 Pictures Taken from Concrete Pumping Vehicle

    And interesting video of 21 march conference at the Stanford University:

    The Nuclear Crisis in Japan:
    http://fsi.stanford.edu/events/the_n...isis_in_japan/

    Direct link to video of conference:
    http://fsi.stanford.edu/events/recording/6615/1/555/

    Video starts out with a 15 minute "economic" analysis, before heading into the more interesting technical stuff about the reactors and what happened.

    PDF of one of the conference contributors presentation:

    If you are interested about radiation info for the local water in Japan, you should look into Japanese local city office / prefecture office web site.
    Also you need to understand Japanese.

    I suppose Fuji is making Film in Kanagawa plant (i.e. Minami-Ashigara City)
    Here are the water radiation test results at water plant in Minami-Ashigara.

    http://www.city.minamiashigara.kanag...isitukensa.pdf

    Abstract Translation:
    Minami-Ashigara City has requested Yokosuka City water office to test for radiation contamination of water.
    Place: Yagurazawa water purification plant (in Minami-Asigara)
    Test Date/Time: Mar. 24 AM 7:30 Cs 134, Cs 137, I 131 All Not Detected
    Apr. 6 AM 7:50 Cs 134, Cs 137, I 131 All Not Detected

    May be this will help you to understand the facts.

    How they could put a nuclear plant in an area near such an active fault and in a tsunami zone amazes me. Just terrible.

    I bought a supply of Acros the day after the tsunami, just in case.......

    Or build it in a rural, mostly low-income area. That's the reason.
