Historically the biggest impediment to nuclear power has been incompetent construction management and project management. Incompetent is a strong word for it but nuclear power plants are the largest capital equipment purchases on the planet. Even modern so-called modular designs can't save poor project management, and learn as you go engineering.

That so mundane and should be easy to fix, right? That's why I bring up scale. Nobody has experience running projects that big. Some things are just too big to manage.
