WOW! 30 years. I don't know what commercial plants that you worked back then, but the people that you worked with may be retired, relocated, or moved into management. BHI and DZ Atlantic are the big contractor players, but there are some other companies as well. You can go to the Employers list on this website and call. They will tell you what you need. Commercial Nuclear has change a lot in 30 years. Deregulation, tighter security, fitness for duty, documented training, NE exam, performance goals, performance bonuses, shorter outages, dry fuel storage, etc. Outages are much more intense, but I have worked with techs in their 60s and 70s who were quite capable of keeping up. Congress changed the tax laws as well. Good luck.
