I have had the displeasure of working at the Kesselring site. I would not recommmend it to anyone in any position. Their philosophy is to micro manage everything and their acceptance criteria is perfection. I have seen many an engineer go through the program, then one mistake - probation, two and you are through. The starting pay for engineers used to be in the low 40s with a gradual increase from there. You may hit the 60s in a few years. That is considerably less than a technician gets in a commercial facility. Since you have a degree, you might try working for some of the nuclear vendor companies. That way you can work some short term jobs doing different things, meet some experienced engineers, and travel a little bit.
