Getting on with a Utility, in Ops, Maintenance or Radiation Protection would allow you to finish your degree in your spare time, after completing whatever training program they have for you.
Short of doing contract RP work, which is part time, any major challenging employer is going to have their own training to go through, plus qualification, etc.... kinda like the Nav (funny how nuclear power is different.. but the same)
There is contract RP work in the DOE world.... and many of those locations are in a "change of scenery", and a change of pace. Also tend to be longer term
Look at the job board. If you read through enough, you may find something interesting. You may just want to try some contract work in the fall - take a semester off and give that a try...
Good luck 
ps - you got a response because you wrote the request in reasonable English, with appropriate punctuation, etc. Eventually, someone is going to give you a "use the search function" spiel - but I gather you aren't sure what you are looking for. So nose around, read some, look over the job boards. After you formulate a bit more for direction, the search function will come natural.... 
Thanks for the prompt reply.
I figured there'd be additional training and schooling, I just wasn't sure of the "total time commitment" it would require, and how much continuing training and education there would be, and if utilities/operators had programs designed to help employees finish school while they work. I tried using the search function for it, but my keywords have failed me; ultimately I'm trying to get a total per-week average time commitment for these sorts of thing.
I mean, power school was 40 hours/wk of school, plus 10 hr/wk of study time; the boat was 70-80 hr/wk on-crew and maybe 40 hr/wk offcrew; college is running me 50-60 hr/wk right now between studying and classes. I assume that training will run close to 40-50 hr/wk as well, and full-time will probably be on the same order of magnitude, with the potential for rotating shiftwork as needed.
I glanced through the jobs postings, and aside from becoming a "road tech," which I assume is a rad tech doing contract work - the nuclear version of a migrant farm worker, as far as I can tell - there don't seem to be all too many jobs outside of rad sponge and general survey work for someone with my qualifications. There is a chemist job in NJ, but I keep hearing bad things about living in NJ and being a gun owner, and since I like to go shooting on the weekends, that's a big no-go for me.
And yeah, I try to be reasonably literate; I find that being able to use English appropriately saves me a lot of grief, especially when it comes to first impressions and whatnot. I suppose that being a technical writer for a few years has given me a hand up in that matter.
Thanks again for your advice, and I'll be sure to use the search function more once I figure out what keywords I need to be hunting for.
If you are a little tired of the school thing then you should be warned that no matter what department you find yourself in (other than janitor) you will be receiving a lot of schooling. Most of which will interfer with your outside schooling.
HouseDad has given you good advice though. A contract RP/HP/deconner will give you a lot more "free" time for more schooling (re: college).
If you really want to get back to the utilities and go to school then try an co-op'ing. I am just sayin' ...

And thank you for the reply as well. I figured there'd be schooling; what I wasn't clear in my questioning was the quantity of training and time commitment for it, and if employers have any sort of program meant to help their emplyees in their professional development.
Could you give me a basic rundown of what contract RP/HP/rad sponge work-life schedule and balance is like? From my reading, it seems that it depends on outages, and that a relative newcomer with minimal experience and qualification - like myself - is at a disadvantage when it comes to competing for job opportunities with experienced professionals who've established existing networks with employers.
