For what it's worth, I'm new to the nuclear industry and thought I would share my experience in case it might help someone who reads this thread and is contemplating the nuclear industry/operator position.
Personally, I went through a community college program that is sponsored by a major utility in our area. Our course work consisted of everything from entry level physics and chemistry, up to reactor theory and kinetics and engineering level thermodynamics/fluid mechanics. Over the course of our two year program we had four "nuclear" classes. Two of which focused on theory and more of the primary systems, the other two were more mechanical concepts and secondary side. In those four classes, most of our handouts and study guides were from the utility and are used in their training at the local plant. Between the first and second year, in order to get your degree you must complete a summer internship. The idea is to do your internship with the utility, although some choose not to take that route (I strongly discourage this choice). I chose to do my internship with the utility and it was awesome. I worked on shift for three months, following all rounds and pretty much trying to see whatever I could and absorb as much information as possible. The course work in the program is not easy, and to call the internship an "eye-opening experience" would be a huge understatement.
As of now, I am scheduled to graduate in May with an associates in nuclear technology, have passed the POSSC and have an interview for an AO position (at the plant I interned in) next week.
A few observations I have had:
Although BZ was considered harsh, a lot of what he said is true in my experience. These companies owe you nothing. Operator positions are highly sought after jobs that require continuous training and carry a great deal of responsibility, and they invest a lot of assets into the hiring to process to ensure they get quality candidates. I have heard there are anywhere from 1200-1500 applicants per operator position posted, and they try to pull from one-third Navy/one-third technical(me)/one-third four year, not including internal applicants. I personally racked my nerves waiting on phone calls and emails after I applied for the internship, and the AO position, because I want it so bad and understand how competitive it is. When they called, they had an answer from me within seconds about whatever they were offering, which was an emphatic yes. After talking with multiple people from contractors to maintenance to everyone I can basically in the industry, I understand that I have been very privileged with my opportunity and will say that operator positions are great jobs that pay well (very well in my opinion) and have a low turnover rate. Again, this makes the market for landing a job VERY competitive, so check your ego at the job board.
As far as the culture, it is not filled with a bunch of jerks by any means. Everyone on my shift during my internship from unqualified AO's up to SRO's and beyond were very helpful, genuinely cared for my safety and are a major reason I have been successful in my program so far. BUT: This is a very serious job, it is not an easy job and everyone in the operations department has busted their tail and put in a lot of work to get where they are. Some have applied for 5 years to get there so, yes, you do have to prove yourself. When you're on shift you are one big team that relies heavily on communication and teamwork and you spend a lot of time with each other, so a "me" attitude will not get you anywhere. As an intern, I wasn't called "noob" or "snowflake" (that may change if I get hired as an AO but in that case they can call me whatever they want because I'll be lucky to be there), but I think what BZ was trying to get across is everyone works hard in operations and they want to make sure the guy beside them is as equally committed and serious.
I hope that my experiences can answer some questions and help anyone who is trying to make the nuclear industry a career.
