ex Navy Submariner here. I know quite a few folks that got out (in the 2005-2010 range) and took jobs in the nuclear field. Some had degrees, some didn't.
The Navy uses Pressurized Water reactors which seem to be a fairly common design in commercial use as well (according to Wikipedia, anyway). Which means a lot of how things work would be similar, and you'd just have to learn the specific systems for how that plant operated (i.e. the designs and how the cooling, electronics, power generation, etc. worked)
I would imagine there would be a lot of overall similarities in core principles and operations, but some specific systems would work differently being on land and likely generating a lot more power + having other requirements for discharges and cooling etc, vs. a seagoing vessel.
