Over regulation of nuclear energy in the US made it so expensive we didn't replace all fossil fuels with it.
Nuclear power in a the US was collapsing due to cost and schedule overruns already before TMI.
Blaming regulations seems like trying to find a scapegoat rather than admitting reality.
I don't think this is true at all.
It's a heavy capex business with very small marginal returns, that takes planning on the order of decades.
AKA, a US company's worst nightmare. Investors don't like that shit, they like half-baked software that code monkeys can pump out.
