I'm not so sure I agree. A big turning point in my thinking was reading a mid 1980s Forbes piece that investigated several other factors that stopped more US nuclear builds. Perhaps most of all was lack of need, there were too many starts resulting in a glut of nuclear power. Second, construction projects were frequently over budget, meaning the power wasn't as cheap as everybody anticipated. Third, yes, there were mid-construction design changes but that was only on a fraction of projects that were already way behind.

Look over at France, frequently touted as a "successful" buildout. But reactors got more expensive the more they built, not cheaper, and they never met their initial goals for number of builds.

And look at the one place with modern-day "successful" builds: China. They like to tout the reactors as great successes, and they are on time and on budget, or at least as on budget as we can tell in an economic system like that. But they missed their 2020 and 2025 five year plan goals for deployment, and will miss their 2030 goal too. Meanwhile, they deploy 20x-30x as much wind and solar each year, each tech. That's after adjusting for capacity factor! So the best nuclear builders in the world are only building enough of it to be low single digits of their energy mix.

Nuclear was always oversold as a technology, always underdelivered, and has not seen a positive learning curve that a normal technology would. It was doomed from the start, IMHO.
