The process isn't very different. Right now, the only enlisted commissioning program for non-degree holders is STA 21, same as any other field. The major difference, and it really isn't that major, is enlisted nukes in power school, prototype, or an instructor the pipeline are the only persons who can apply to the nuclear option of STA21. There are about 60 nukes selected each year, including 10 to 20 staff members.
In my selection year, two nukes were chosen to be pilots. It is very difficult for a student in the nuclear pipeline to be selected for any other community besides the nuclear option.
If you enlisted into the nuclear field solely for its commissioning potential, be careful. The system is still very competitive, and you might want to take a look at the STA 21 website to check the other requirements to ensure you can be eligible. Don't count on the nuclear field to give you too much of an edge in the commissioning system, ESPECIALLY if your goal is to become a pilot. You need to bust your proverbial ass. Count on having a minimum GPA of 3.6 in A school and power school to even be considered. Count on having at least a 3.7 if you expect to be competitive for the pilot community. Count on waiting a few years to prove yourself at sea, because you're not likely to be selected for the pilot option out of nuke school.
Preferential consideration is given if you need less than 2 years to complete college. You have a year to get some serious work done in that direction. If you're waiting a year already, ask about the Navy college program. They'll pay you E-1 if you maintain 12 credit hours of enrollment in college for up to 12 months before going ot boot camp. I recommend taking all your gen. ed. courses.
