    Nuclear disasters, such as Japan's, due to natural disaster can happen anywhere! Here is why and what we can do about it.

    Thank you for your posting. I want to comment about the Tunguska event related to nuclear plants that are not close to the ocean.

    Based on what was researched and simulated related to the Tunguska event, it appears that a space object entered the earth atmosphere at an angle (30 degrees) and speed (21,600 MPH) that prevented a direct impacts into the ground. Instead the super-heated metal/rock caused an airburst and then exploded 4 - 6 miles above the ground flattening everything for 43 miles in width and 34 miles in length as it came apart.

    The impact of this rock/metal coming directly to earth for impact would have been much less widespread. If something about the same size or bigger exploded of parts of the United States where there is a nuclear power plant, the problem would not be the damage from the airburst. Rather, the problem would be:

    1. No power for an extended period of time if transmission lines are knocked down/out.
    2. Access to water for emergency cooling for many reactors could be a problem (You need large amounts of water to do what the Japanese have been doing with seawater to keep the reactors cool).

    So the questions are:

    i) Are backup generators protected from an airburst like event?
    ii) Are power lines providing power from the back up generators protected?
    iii) Is there sufficient water available that if the answer to i) and ii) is NO, that manual spraying/cooling could be done?

    I would think that not every plant needs to have plan C available for a Tunguska event, but at least by region, stage the equipment that can be moved in a matter of days to the location needing it most.

    We also have to hope that a larger Tunguska like event is not going to happen for at least a thousand years.
