My concern with reactor operators is that it's a dying industry due to the challenges in getting a commercial reactor permitted and constructed, along with the costs of renewables driving nuclear out of commercial viability.
With that said, I think there'd be great value in an organization advocating and enabled students to get into these "experience-in-lieu-of-degree" types of jobs you mention. Mike Rowe is doing this [1] as part of his mikeroweWORKS Foundation/"Profoundly Disconnected", but my opinion is this needs to be performed at scale nationwide (such as getting involved with school counselors at the high school level).
