A few scattered thoughts on the topics from above:
The year after Three Mile Island was the first year we had House Finches at our feeder. My mother thought that they looked like mutant sparrows, so we there after called them Three Mile Island Sparrows.
I remember going to Shippingport reactor in 1967 as part of a class trip.
I did some reading on DOE emergency publications at Hillman Library one evening. Up until Three Mile Island (TMI), most of the papers were on terrorist attacks against nuclear reactors. After TMI, they were on accidents at reactors.
