I agree with gamecock that you are thinking too deep too early, as you still have the toughest part of the pipeline coming. Although, I will say that is a good sign. Officer or enlisted, your future is bright in commercial nuke power, but you will see that there is little difference between the opportunites. Here is a generic break down of opportunities (mostly focused on ops);
Enlisted;
6 and out, not a crap bag = start at NLO at some plant. About 2 years out, make 100+K/yr. Work your way through the ranks as RO then SRO and beyond. This is by far, the preferred path.
8-10 and out, qualified EWS >2 years = start at NLO, or get and instant SRO job. If you got your degree all the opportunities for officer apply, which basically adds engineering. You should note that I know 8 and outters with RPI engineering degrees sitting in NLO classes as we speak, because they never qualified EWS. EWS is key to instant SRO as an enlisted guy.
There will also be many other opportunities such as maintenance or radcon if you aren't interested in ops.
Officer;
Start at NLO
or more probably,
Get an instant SRO job
Also Engineering (pay is less) will be another good opportunity.
The industry doesn't really hold JOs and enlisted in any different light, so the question is what do you want to do while you are in the Navy?
In regards to all of this, keep your nose clean, try to excel (AKA resume build) by qualifying anything you can and going to as many schools as possible. Don't be a dirt bag, and gain some good experience. Remember, if you just do the 6 and out, there are lots of you so try to be a step above the rest.
As far as the new plants, it doesn't matter right now if they never even approved another license. Most of the current plants are so short staffed that if you play your cards right, you will get a job anyway.
Good luck!
