I graduated last year with BS degrees in physics and applied math. I also took heat transfer and fluid mechanics courses which I enjoyed. I'm looking into various areas to complete a phD in and nuclear engineering is one of them, but I know little about it. I had some questions about how much physics and math is involved in the theoretical grad courses in a phD nuclear engineering program: 1. How much quantum mechanics and E&M is used? I thought quantum mech was ok but didn't really like E&M as much. 2. How much heat transfer and CFD is used? What areas of ME besides those is also used in nuclear eng? 3. How much math is involved? Is there heavy use of linear algebra, numerical analysis, probability/stats, PDEs, and other math? Basically my main concerns with applying to a phD program in nuclear engineering are: 1. I haven't taken any classes in it so I don't know if I'll like it. 2. Do nuclear engineering graduates find jobs easily outside of nuclear engineering? such as mechanical/aerospace industries? 3. Is a security clearance required for jobs in the nuclear industry?
