Before I start saying anything: DISCLAIMER: I have not attended RPI and anything I say here is based on my potentially faulty memory.
I believe RPI had a program worked out to allow staff at NPTU Ballston Spa to take the courses they needed to get a BS in the 3 years they are stationed in NY. Basically they had class schedules so you could attend no matter what shift you were on. I don't know what the degree was in, although I think it was either nuclear engineering or nuclear engineering technology. Since this course of study requires on campus classes, if you don't make it through the pipeline, you're probably not going to use this.
On the other hand, Old Dominion University, Thomas Edison State College, and Excellsior all accept credits from Power School and you can either transfer credits from local community colleges or take their classes online, so they might be a better choice, after you've finished all the training. DO NOT ATTEMPT TO TAKE COLLEGE COURSES WHILE IN THE NUKE PIPELINE! You are ineligible for TA and the GI Bill as a student, and you'll have more than enough school to keep you busy without it.
