Studying something in grad school likely makes you familiar, not an expert. I would be skeptical of anyone without at least a decade of industry experience. No one becomes an expert by going to grad school; you have to build real things under real constraints. I went through a selective hard sciences program (coincidentally including nuclear chemistry) and industry people forgot more than we ever learned.
School creates confident sounding opinions but it rarely creates deep domain expertise. I would put more value in the opinions of people that have built or worked on real systems.
And to be clear, I am broadly pro-nuclear. I think it is a critical part of the energy mix that has been maligned on anti-scientific grounds by parties with an agenda separate from providing clean, inexpensive energy.
