MountainBiker, We are not sure if even the nuclear power plants will have enough fuel for more the two weeks, but I do know that almost all military vehicles will still work in a EMP attack so the question is do they have any plans to refuel the generators if the generators work since the generators do have wiring and electronic starter. That is a big question. But I thing someone knows this and they have some type of plans I hope.
I think the real problem will be the used fuel rods which need to stay cool. Robin is right that the reactors have an auto shutdown so that takes care of the plant but some of these nuclear plants have a lot of used fuel rods, so that is were I hope the military has some type of plans.
