Hmm. Ok, let's see here...
* https://www.eia.gov/energyexplained/nuclear/nuclear-power-pl... (2019)
56 NPPs, 809,410,000 MWh (actually generated)
* https://www.usgs.gov/faqs/how-many-turbines-are-contained-us...
~60,000 wind turbines (I've seen numbers between 57,000 and 67,000.)
* https://www.eia.gov/energyexplained/wind/electricity-generat... (2020)
338,000,000 MWh (actually generated)
1NPP -> 14,453,750 MWh/yr
1WT -> 5633 MWh/yr
1NPP == 2600 WT
You are absolutely correct.
I highly doubt that. The Tricastin NPP for instance (https://en.wikipedia.org/wiki/Tricastin_Nuclear_Power_Plant) is a rather average one, producing up to 3660MW. An average windmill output stand around 2.5MW, hence equivalent 1464 windmills simultaneously running before accounting for the load factor.

This one is about a nuclear reactor, not an NPP. Typical NPPs features 2 to 6 reactors.
