Careers in the fields of Nuclear Engineering or N. Physics?

Earlier this past week, I asked a question about the differences between the majors of Nuclear Physics and Nuclear Engineering. I was given wonderful feedback and answers though I still have many questions. I am wondering now if anyone can give me an explanation and some examples of the career choices involved in both majors (governmental jobs included). My thoughts have focused in on jobs with the Department of Defense but even that has such a broad range. If anyone can give me some good examples of careers that could be pursued with degrees in both N. Engineering and N. Physics, I would really appreciate it. Thank you.
