I would suggest that anyone looking into commercial nuke power look long and hard at the utility prior to committing and moving to that plant. Some of my friends there were "un-hired" during the training. Condensed version.... If you do not maintain an 80% rolling average during your training... YOU WILL BE LET GO (and the precious Union won't help). Sorry if you bought a house, started your kids in school, used up your Navy move, etc, You WILL be looking for another source of income to live on!
Just a thought prior to agreeing to Southern Company. There are plenty of other utilities to look at first (Progress, FPL, Entergy, Excelon ...) Do your homework first.
