Some utilities require an A.S. in a related field or a B.S. in any field (or Navy Nuke) in order to be considered for OPS training programs.
A Master's Degree could help in certain positions above Shift Operations (OPS Manager some plants, Plant Manager or Site VP at some other plants). But there is probably no advantage of a Master's over a B.S. for getting RO/SRO license.
The programs advertised are accurately labelled technical. Typically these offer "Engineering Technology" vice "Engineering" degrees, because the operators are not typically going to be engineers. There are engineers who decide to become operators, but it is not a necessity.
I based my assumptions on the program you are considering to be in a similar outlook to the ads I pointed out. These are quite distinct from the schools out there with Nuclear Engineering BS / MS programs.
The advantage to one of these programs vice Penn State would be time, distance, and $$. 2 years after being hired by a commercial nuclear power plant, an AUO (not licensed RO/SRO, but waiting for an opportunity to go to license class) will be making $60K per year before overtime (at some sites making over $100K by working lots of OT). That is better than starting pay for many engineers, and the top end is higher than for most engineers.
