I was just wondering about this field and I have a few questions. 1) Is it possible (or how typical is it?) to get a PhD in Nuclear Engineering with a B.Sc in Physics? 2) Is a PhD recommended if I want to work in this industry? 3) I don't know if I want to do pure research (ex. experimental plasma physics) or have an industrial engineering job. I'm more interested in the physics behind the subject, especially fusion and plasma physics. What kind of questions should I be asking myself to decide?
