Typically for an NLO I'd say you'll be in the training program about a year, 14 months on the outside. TVA is quite a bit longer but I believe we have to much no value added stuff in our NLO Program and should be working towards reducing it.
So I'll give you my best shot..
3 weeks of general training. This will include your General Employee Training, Radworker, Respirator, anything else the facility determines to be general in nature. This is typically 8 hours M-F with a half hour unpaid lunch for a 8.5 hour day.
4 weeks on shift familiarization time. The NLO will rotate with a shift.
5 Months Theory and Systems Training. Theory will be 3 to 4 weeks. The rest will be systems training, some Admin training, and Tagout Training. This is typically M-F 8 hour days with a half hour unpaid lunch. I've also seen it done M-Th 10 hour days with a half hour unpaid lunch.
After that you report to shift and rotate with a shift for quals.
SRO Depends on the Utility and how many units it has on the site in which you are employed. Here's a typical schedule.
During GFE (Theory) M-F 8 hours with a half hour unpaid lunch.
Systems Same as above though I've seen M-Th with a half hour unpaid lunch with 10 hours of class.
General Operating Procedures/Abnormal and Emergency Procedures: Th-Sunday 10 hour days with a half hour unpaid lunch. This is due to simulator availability. My former utility utilized a backshift shedule in lieu of weekends. When possible they even worked the ILO guys into the normal week. At a dual unit site this is almost impossible.
License Prep (all material is taught, now its just drills) Usually the same schedule as for GOP Training.
Onshift Time: Rotating either 8 or 12 hour shifts with an Operating Crew.
Usually neither group is authorized OT with the following exception: During outages sometimes training stops and trainees assist qualified operators at the plant. They'll usually get at least 6 12s during this period (and are subsequently ruined for any further classes later down the line

) . Also if you are on 12 hour shifts at least two shifts a month are of 4 days for a total of 48 hours, at least part of this is time and a half if you are an NLO or a Union RO. If you're an SRO you just end up biting the bullet!
Hope this helps!
