I worked in commercial nuclear power for a while, including a stint at three mile island. The regulatory compliance burden alone, from the NRC and DOE, is crippling financially.

I really hope pre-approved, pre-built modular reactors lower costs, delays, and regulatory overhead.
I'm also hopefully that molten salt reactors, once viable, are different enough to not be hampered by the full breath of traditional reactor regulations.
