> It must be far less than is needed for mining the uranium needed to generate the same power. Think about it; the copper required for the wind turbines is a fixed one-off cost that lasts the lifetime of the turbine, and can be recycled. Nuclear reactors need a continual supply of uranium (about 27 tonnes per year for a 1GWe reactor: http://bit.ly/3voR0II).

A single wind turbine can contain 3.6 tons of copper[1], so using your source for uranium used by a nuclear power plant in one year. Just seven and a half wind turbines use as much copper as a nuclear power plant uses uranium in one year.

If you replaced the ~100GW of nuclear power capacity in the United States you would need about 360,000 tons of copper. It would take the current US nuclear fleet ~133 years to use the equivalent amount of uranium. The above also assumes that wind turbines runs at 100% capacity which we all know they won't. So your going to need an additional 2 - 4 times more turbines and copper to replace the current US nuclear fleet.

> Furthermore copper concentrations are typically around 100 times higher than uranium concentrations, which means you need far more uranium ore than copper ore to produce the same weight of metal. Copper has been extracted with relative ease for thousands of years.

Also copper concentrations in typical copper ore is not 100 time greater than uranium concentrations. Copper concentrations are about 0.6%[2] and uranium is 0.1% - 0.2%[3].
