Hey Mike,
I would just call Scott and get on with TMI and Peach this year. You have quals in the exelon system. You would be a retrunee at Peach, which should set you up to get in at TMI, (I bet Stu would let you work for him in a heartbeat) plus it's going to be a longer outage this fall. (I know it doesn't help for the spring.) And you would get 3+ more months of Jr time in.
But Even if you keep returning to Peach for the next 2 seasons, You should get your 18.1 by the following spring and then you won't have to fight for Jr spots. You can fight for 18.1 spots!
