      Was a CAT 5 and the plant almost took a direct hit.  The 'cane laid waste to nearby Homestead, FL but Turkey Point suffered mostly superficial damage.

        station blackout. That is: the grid goes down due to high winds and the plant is required to use diesel backup. This happens ever few years someplace when an area wide black out occurs. Power is always restored in a few days.

        The issue is where the diesel fuel supplies and/or reactor cooling pump(s) are somehow made inoperable. This is what happened with Fukushima. Thus the industry has developed but protocol and engineering solutions to solve this potential events (including, but not exclusively, hardening of pumps and fuel tanks, relocation* of fuel tanks, extra portable diesel fuel pumps with own source of fuel, etc etc).

          I've always had a hard time figuring out why nuclear power plants aren't allowed to use the very power they're generating to run all the other auxiliary equipment in the plant.  Why do they have to rely on power brought in from elsewhere?  You would think that the power they were generating would be the most reliable inside the station.

            Turbines have minimum steam flow lower limits. Usually about 15 to 25% of maximum load depending on type and size. So this % is way and above the minium load of the unit.

            A 1150MW gross output plant uses something like 50MWs for it's station use. Or slightly under 5% of the total output. This is fine when the reactor is outputting say it's permitted minimum of, say, 450MWs but can't be achieved give my guestimated minimum load of 15% or 160MWs.

            So that's the basic reason. Excellent question BTW.
