Following up on the AOPA article linked to by the OP this morning, here's the original Sep 2001 FAA notice about flight near nuclear plants:

Note that you cannot "CIRCLE AS TO LOITER IN THE VICINITY" of nuclear plants, etc.

And here's the clarification that the SSA got in Mar 2002 from "FAA Air Traffic" regarding the "no loitering" rule:

Apparently there isn't anything written from "FAA Air Traffic" to the SSA on this subject. I'm also not sure that the toll free number the SSA set up in 2002 still works.
