I'll throw in my take on NLO training at an Exelon East Coast BWR.
You'll most likely only get paid for 40 hours. About 2-3 hours a day have built in study time/lunch.
I took a clue from the licensed class upstairs and came in on the weekends to study (pay or no pay, it worked in Orlando).
We received formal lectures for all systems, subsystems, etc. with built in objectives and references. We also had what were the "house notes" which were a combination simplified one-line with embedded notes (set points, alarms, automatic features, trips, interlocks, etc). We also had P and IDs which to me are more useful in the plant than they are in the classroom. IMHO, a P and ID can be too overwhelming when you are first familiarizing yourself with complex systems.
Most of the lectures came with power points.
I used the skills I honed in the Navy. I actively listened to the lecturers, highlighted information they repeated a few times, used mnemonics, and made prodigious use of dry-erase and white boards to write out objectives.
A lot of the guys quizzed each other. Use as many senses you can to learn stuff: read it, hear it, speak it, see it.
If you have your dosemitry, get with an NLO on rounds and walk systems down. Go see the stuff that is talked about in the lectures. Make it real.
Not sure how your training is broken down, but we did classroom for several weeks, broke for 5 weeks plant familiarization, and then came back for more classrooms. After formal classroom training we went to the plant with our qual books for OJT/TPE.
OJT: On the job training
TPE: Task Performance Evaluations
At the end of classroom training I had the highest average out of 20 (>97%). I am pretty sure I was not the smartest, but hand's down I was the most motivated and in my experience, motivation and enthusiasm will get you far.
Good luck.
