(former Navy nuc operator here) Although the direct technical skills from my time really don't apply. The idea of the "block diagram level" knowledge in your mind and the basic troubleshooting process instlled in me there in my training has served me VERY well over the course of my IT career. Not to mention the broad (not necessarily deep) mechanical system knowledge of things like power, HVAC, emergency generators, UPSs, etc. Data center infrastructure has a lot of similarity (at a smaller scale) to safety systems at a nuc plant.
Yeah, not broad based the way the article says, but for my more specific part it worked for me!
