I was thinking that too. There should be plenty of grads from the US Navy Nuclear Power School, and the officer grads are likely to have at minimum undergrad engineering degrees either from the Naval Academy or civilian universities.
My mother was office staff at a nuclear plant for a number of years in the late 80s/early 90s (and for reasons passing understanding, received training as some sort of emergency/backup operator, despite making very clear that in an emergency, she'd be driving away as quickly as possible). From what she tells me, former US Navy officers and enlisted were absolutely everywhere, as both employees and NRC personnel.
