    She's in Ozark and out of range of this. I hope.

      I got information from the scene just a little while ago.

      A work crew was moving a very large generator part when it got away from them.  

      The reactor was not involved.  Anytime there is a serious accident, especially if it involves a fatality, there is a strict protocol that must be followed. That includes a shutdown and checks for radiation. It may be disconcerting to see inspectors running around with radiation detectors, but that is a required procedure.

      Unfortunately, it is the type of accident that happens every once in a while at any industrial faculty where workers have to move multi-ton pieces of equipment around.  The only reason this made national news is that it happened at a nuclear plant.  Had exactly the same thing happened at a hydroelectric plant, it would have been just a local news story.

        of this situation is the grid blackout for not the one, but BOTH reactors. The second of which was humming along at 100% power. The damage to the electrical circuitry (more detailed analysis soon from someone who knows the systems) appears to have interfered with in-plant systems as well as grid feed. The scrammed unit 2 should not be on convection cooling per the date of this notification. That means the EDGs aren't managing to power the RCS pumps.

        Unlike the spent fuel pool circulation system, the RCS [Reactor Coolant System] is supposed to be powered in an emergency situation just as the secondary heat exchange system is, to carry away excess heat. Peripherals - including the power generation system - are supposed to get automatically isolated to conserve whatever capability of controlling the core reaction to the primary. A scrammed from 100% core generates a whole lot more heat a whole lot faster than a plant in outage shutdown status.

        Just mentioning the difference highlighted here, in case they need to confuse things even more hopelessly over the next few days.

        Mom didn't hear anything about this on the local news. She's not the news addict I am, though.

        I know she's OK, but she has friends in Russelville she may have been visiting, who were the ones who mentioned the accident to her in the first place.
