Which regulations?

What would change in the construction process?

China builds the same designs as the EU and US, yet faster. What is different?

I saw toooooooons of reports of construction mishaps in the US at Vogtle and Summer. I didn't see anything about "oh if we changed this sort of regulation it would have saved us money."

It's a very worthwhile to read the retrospectives on these builds. There are lots of plans of future builds of the AP1000 that would be cheaper, but none of the plans even indicate that a regulation change would help.

I beg of people who say regulations are in the way: which regulations? Concretely, what should change to make construction cheaper? Pun intended.
