MMCM --
First of all, thanks for sticking it out and serving your country, I really appreciate it.
You weren't on the TR or at NPTU Charleston anytime in the past 6 years by any chance, were you?

Second, I'm by no means an expert, and I myself am still vying for my entry into commercial nuclear power. I'm finishing up some college work right now and will be jumping back into the work force this summer. But, I have learned a *lot* from all the guys/gals here on NukeWorker in the past several months, and I'm working on compiling an FAQ for commercial power newbies, based on what I've learned here.
To your questions: First of all, your ELT experience counts for quite a bit, *especially* if you've been on a decom crew or a ship refueling. Experience during that time counts on a 1 month:1 month basis. Otherwise, being an ELT counts for 12 months of equivalent experience towards the ANSI 3.1 requirements to qualify as a Senior Health Physics Technician, which requires 4 or 5 years of relevent experience (or something close to that).
If you have completed a college degree, that counts for another 12 months, also. That's what I'm counting on to get into commercial power, since I was an EM, which really gets me nowhere in the HP field.
While you're waiting to get out, you might want to study up for the theory exams. Somebody else chime in here, but I *think* you have enough qualified experience to probably take the NRRPT exam, which is the standard certification for civilian HP techs. Also, the Dept. of Energy CORE exam is the gateway to DOE work. This site has practice tests and study guides available in the "Study" section.
I would imagine that your experience in supervisory roles would count for quite a bit if you found a full time, in-house position at a power plant. A lot of plants have a position called a Shift Technical Specialist or something to that effect, that is basically a supervisory/technical advisor type position, available in Operations departments. As a road tech, I have no clue what is available.
For full-time work and some really good career advice, there is a well respected member of the NukeWorker.com communityu that is a nuclear recruiter, but I would never label her a "head hunter." Her user name is "NukeRecruiter". You might want to send her a private message here on the system. She helped me out a LOT when trying to figure out what to do to maximize both my Navy nuke experience and college education.
Check out the job boards here, and call directly and talk to the contract companies. The two largest contract companies for HP work are Bartlett and Numanco. They get the vast majority of the contracts for outages.
I hope I'm not breaking etiquette by mentioning this, but another individual you may want to talk to that helped me out a lot is Scott Wolf of the McLain Group in New Orleans. His number is 985-725-0290. He has a lot of experience with military-civilian transitions.
Well, I hope that is a good start.
Good luck, and welcome to CIV DIV!
Take care!
