1 Gigawatt equivalent of solar panels is 2500 acres.
All those solar panels require much more metals and cement than the nuclear plant. And the lifetime of solar panels is also twice shorter than the nuclear plant.
Utility scale PV doesn't require any cement/concrete at all. The mountings can be anchored to the ground with steel earth anchors. This is typically cheaper than using concrete, and faster to install.
The area requirement ignores that land is extremely cheap, as little as 1% of the cost of a utility-scale PV field in the US. Building an expensive nuclear plant to save cheap land is deeply foolish.
