That is great advice, I guess this thread will end up in a different direction than I hoped but it is nice to hear about specific jobs.
Outside of knowing how to operate the sh*t out of a nuke plant, I am pretty stupid, so I guess I don't know where you want this thread to go. How are we supposed to answer your original questions without giving specific examples? Or, if you want to know what salaries to expect, how about I just say anywhere between 50-200K? That is about as broad as you are looking for, isn't it?
On the topic of corporate jobs, any idea what they involve? And I know I've read about it on the forums but what are the job specs for an SRO?
I can't speak intelligently about what corporate jobs you'd be qualified for, except maybe engineering. You certainly wouldn't be hired into anything that is in the path of managing operations of nuclear facilities. I have heard of the occasional Admiral that got hired in at the executive level, but outside of that, I am not sure. Perhaps one of the more experienced SROs like Broadzilla can speak to that. The point is, everyone has to get an SRO license (for the most part) at some point. It is called "getting your ticket punched." That license is almost always held above any degree you obtain. I know VPs with no degrees but they have an SRO license. The SRO license is supreme, and there is nothing you can do in the Navy or college to change that.
What do you mean by jobs specs? What the job entails or what is required to become an SRO? In either case, both of those are covered extensively on this site so I am not going to recover them..., and even if the last post was 2007, it is still current.
What I'm gathering is that 5 years in or 19.5 years in are about the same if I don't get to O-5? Or are you saying that I should get to O-6 to get the better standing in the civilian world? I'm not sure where you are cutting it off at.
What I am saying, which I am clearly not getting across well, is that all of your degrees and Navy experience add up to about 2 bullets on your resume. To the commercial nuclear power world, they are almost meaningless and merely get you in the door for an interview. For 9/10 Navy nukes, the highest you can hope to hire in at is SRO. I am not sure what you think you should be entitled to other than that. You should count yourself lucky that commercial nukes even allow people to hire in at SRO. There is no clear cut case, is what I am saying. Like I said before, I know an 05 who was my Commanding Officer on a Fast Attack submarine who hired in at the same level I did, a lowly E6 blue shirt. Hell, there is even a 6 an outer enlisted nuke on the site that hired in as an SRO. Commercial nuclear power is the great equalizer. If you want to go higher than that from the onset, then you need to be super special and be the 1/10 that what I said doesn't apply to. Maybe you are, only time will tell.
Are there any theoretical jobs in the Nuke Eng field rather than mainly operational? I know a few of the Nuke Engs at the local plant and they tell me there's not a lot of Math involved... I do especially like math 
I can't speak to that outside of a nuke plant, but I don't think the "nuclear engineering" would be too interesting to you based on what you said, at a nuke plant. They don't do any real "engineering," like design and what not. Sure, they put a core together, but it isn't challenging and where I've been, they pretty much use a computer program to do it anyway. Now, I am not and never will be in nuclear engineering here, but they showed me what they do, and most of them aren't happy..., mostly because the work is mundane and they are severely underpaid compared to ops. So take what I say about engineering with a grain of sale. Like I said before, according to the engineers in my class, little credit is given to your Navy experience unless you are the rare special snow flake. Again, you may or may not be, only time will tell.
What it boils down to for commercial nuclear power is this;
If you want to maximize your pay when you get out, then SRO is your only choice in 9/10 cases. If you are that 1/10 person, then I don't know.
If you want someone to drool at your college accolades and Navy achievements, you need to look outside of commercial nuclear power.
Good luck.
