For typical nuclear power plants the land usage isn't anywhere close to what you claim:
>...A typical 1,000-megawatt nuclear facility in the United States needs a little more than 1 square mile to operate. NEI says
wind farms require 360 times more land area to produce the same amount of electricity and solar photovoltaic plants require 75 times more space.
To put that in perspective, you would need more than 3 million solar panels to produce the same amount of power as a typical commercial reactor or more than 430 wind turbines (capacity factor not included).

Are there countries where the land use for nuclear power is orders of magnitude larger?
