So the one that started construction in 2013 doesn't exist?
20 years between plants isn't that big a deal. They're not building houses. Nuclear reactors take decades to built. It's one of the reasons they're so expensive.
It's possible to build these things in parallel, so "each one takes 10 years to build" doesn't mean you can't still bring one reactor online each year.
Either way, new reactor construction is not currently a significant source of new generation capacity in the US, and so I think it counts as "basically stopped".
