    I think they do, and they have a triple backup system for keeping the power going. Beyond the triple backup...

    "...So even in the face of a complete station blackout—you don't have any power at all—there are methods for using the steam-driven pump to continue to keep cooling going."

    I think once they get the temperature down, there won't be a problem until they get power back. They normally pump water through the towers where the rods are. The pumps aren't operational without power but once the rods are cooled down they won't heat back up until the plant is back in operation. Since they are heated to a very high temperature in order to generate nuclear fission and subsequent power, they don't cool down very quickly. Chernobyl resulted because the pressure reached a point it caused the entire tower to collapse and release a massive dose of radiation into the atmosphere. That happened because the tower was old and the Russians had not maintained it very well. The atmospheric radiation would have to increase by another 1000 times before there would be a real health risk.

    What they aren't saying is that that is not a health issue because the dose level is still very, very low.

    I can't believe the devastation we are watching. I am numb with shock.

    An hour ago, CNN had an expert on who said exactly what you said. But they still seem to by hyping the issue.
    Creating drama!

    This one's from CNN.

    http://www.cnn.com/2011/WORLD/asiapc...x.html?hpt=T1#

    It seems there are many experts - Japanese and international -working on this and I am confident that they will find a solution.

    It's best to not panic and wait to find out exactly what is happening, after all the details come in. I don't trust Fox news a whole lot because they tend to sensationalize things.

    The *normal* dose levels in a nuclear facility have to increase by almost a million times to reach dangerous levels. Which won't happen barring a complete breach of the cooling towers. Workers don't even wear radiation protective items. Their occupational dose is less than my students who do have to wear lead.

    My brother is a free spirit and likes to be on the everything is bad for you except for natural things bandwagon. He is posting links to the sensationalism articles and have friends who are out there. I asked rfisher if I could post some of her level headed responses and she kindly said yes.

    I expect that there will be rants on me because I am telling them to knock off the sensationalism and be concerned about the people of Japan and elsewhere.

    They are on battery power now. It's their last backup.

    Walked 7 hours back home from work. My legs are swollen. But that's absolutely NOTHING compared to the people living around Miyagi, Fukushima, Nagano etc.

    My family and friends are alright. But I couldn't sleep at all. I want the earthquake to stop. I'm also shocked to learn that they found 200 to 300 bodies on shore, probably casualities of the first Tsunami.

    ((((MINAM)))) Could you not remain at work? I'm glad you and your family and friends are OK.

    They're bringing in replacement diesel generators, but the clock is ticking.

    Phew, glad to hear from you MINAM! My friend in Tokyo is still sitting tight in her office, 14 hours after being stranded there by the earthquake. It's hard to sleep and her stomach hurts since all she's had is beer and ramen. But she chose to stay at work rather than walk the 9.5 hours back home.

    I'll say! My dad freaks out about me being around radiation at work, but in school I just worked with tritium and here we work with potassium32, which you can block with a thin piece of acrylic.

    Still, hope they get the cooling fixed so they just have one less thing to worry about.

    Can't even begin to think about the consumable items, water, food, etc, that people will need. I take it for granted that I can go to my refrig and get food/water. And my medications - if I was stuck in an office building or car or anywhere, I wouldn't have them. Someone said it was like 9/11 - just a feeling of hopelessness for the people in Japan and others in the wake of this disaster.

    That sounds awful, but I am glad you are safe.

    In 1995, I was an exchange student in Osaka. On 17 January, I woke up at 5:41am and wondering why I was awake. At 5:46am what became known as the Great Hanshin earthquake struck not far from where I was.

    Yesterday morning I woke here in Ireland at 5:46am exactly which 2:46pm in Japan. The time the quake struck...

    Mr. allezfred's cousin who lives in Sendai left on a business trip to Tokyo yesterday morning. While she was on the 42nd floor of a building that was shaking in Tokyo, it could have been much worse.
    To think that fun is simple fun, while earnest things are earnest, proves all too plain that neither one thou truthfully discernest.
