Well the nuclear division is broken into 3 different jobs. Electronics Technician, Electricians Mate, and Machinist Mate. Note that these jobs are VERY different than what conventional ET, EM, and MM's do.
ET(Electronics Technician) takes care of all the computer related aspects of maintaining and operating the ships nuclear reactor. EM's handle the electrical aspect of it, and MM's handle the piping and make sure all the physical components do what they are supposed to do, when they are supposed to do it.
You WILL sign a NDA upon enlistment, and will recieve a government clearance after A school, but before C school. That means that what I learned and did I cannot talk about for 99 years or until I die, whichever comes first.
My sign-on bonus was 40,000, but I made them beg a bit to enlist me...Pay is same as other jobs, HOWEVER accelerated advancement means you make more money and rank higher than other ALOT faster than you would in other jobs.(BTW, people with other jobs despise this, HEHE)
If you are scientifically inclined, i.e. REALLY advanced chemistry, physics(both conventional and quantum), and math, then it is AWESOME.
The nuclear program is beyond stressful according to my coworkers who did that in the Navy
Yes, it is unbelievably stressful. The general "type" that goes for this job is the loner types and the ones who got A's school without even cracking a book. Unfortunately that adds to the stress, because most have to relearn study habits.
