OH, and yes, they can take my title of Nuclear Engineer from my cold dead Naval Reactor Operator hands when I scram to the big Reactor in the sky!
I worked with one person who was former enlisted Navy and serve a lot of time on nuke boats. No college degree. Still as knowledgable as most engineers, however. He’s currently on track to being on the plant management team of a major refinery.
I have hear that even though there are specialties on the boat, most everyone on the boat knows at least the basics from how to load and fire a torpedo to how to run a reactor. Everything except how to operate the radio (thank the Walker family for that one). Everyone I have worked with that was nuclear Navy was top notch.
