Thanks for the detailed replies !
Basically I'm seeing two possible paths that I can follow :
1) Enter the industry in the IT role. Even though this seems like the easier path, I'm kinda keeping it as a second option (I love my dev job, but I just want to do something more "hands on", get my hands dirty [.. with something non-radioactive preferably

]).
2) Take the Masters in Nuclear Engineering and enter the industry proper. Now I'm a total noob when it comes to the terminology and business of nuclear power. JustinHEMI mentioned that in this case I would probably enter as a NLO. After digging around a bit I figured out that it means Non-Licensed Operator. Could someone please explain briefly what kind of responsibilities / roles a NLO holds ?
The kind of work I prefer to be doing is probably managing / maintaining (as I mentioned before) control systems , something that involves computers , micro controllers , systems integration etc. but I'm flexible.
I'm more than willing to work in remote areas, isolation, non-optimal environmental conditions, as long as the work is engaging / interesting and pays good

Another thing I'm worried about is the fact that I won't hold a Bachelors degree in Nuclear engineering. Will having a background in CS and Masters in NE, put me at a disadvantage compared to my peers ?
Finally, there are a lot of new plants under construction around the world, but what about the nuclear research labs, is there a renewed push into new reactor designs ? Any jobs opening up in R&D ?
