Most of the US's problems on this have little to do with putting too much priority on safety. There are countries that show that you can have a sane regulatory process and still get well priced nuclear. France from the 70s through the 90s and South Korea are the classic examples. Neither compromised on what's actually needed, but both cleared the way on redundant walls that don't demonstrate or stop anything bad from happening. You can achieve both greater nuclear safety and reduced process burden through standardization, which is how most places that have done it got it done.
