<p>My father was a nuclear reactor officer in the U.S. Navy, and has stated that nuclear engineering is the most difficult thing he has ever done. He went through Nuke School in Florida when it was rated by Time Magazine as a more difficult program than Harvard Med. and Law School. He said noone had ever received a 4.0 GPA throughout the progam, and only 2% of people who began the program actually ended up graduating. I’m sure the naval program may be a bit more difficult than at a typical university, but you would need to be ready for an extremely rigorous program if you wish to go into nuclear engineering. My father eventually left the field after six years because he got tired of living in a rural area in Iowa; that is something to take into consideration as well: most nuclear powerplants (where you would be working) are nowhere near urban/suburban settings.</p>
