Some key insights from the article:
Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.
They had to switch halfway through which is what added the cost that’s not a realistic cost per reactor
Ok, current projections are still for the next two AP1000s at Vogtle to be something like $10 billion. That’s just not cost competitive with solar/wind. And it’s also not very realistic to assume that there won’t be cost overruns on the next one, either. Complex engineering projects tend to run over.
Next two? After you mentioned it I tried googling and can’t find anything about current projections for new AP1000s at vogtle.
This paper lays out the cost projections that one could expect with the lessons learned from Vogtle Units 3 & 4, with the tax credits and government guarantees available as of 2024:

According to the link you listed an AP1000 costs $66/MWh where as from the ember report that’s linked in this article solar plus storage for 97% uptime cost $104/MWh in a sunny city. In Washington DC it would cost $124 and only be able to maintain 81%. I still stand by even with the higher cost that solar + storage is a better option in places like Arizona, Nevada, Southern California ,etc. but nuclear is not as much of the high cost boogeyman as you are making it out to be
