You also have to extract copper and steel to build wind farms, and drive trucks to install solar panels. The net greenhouse gas emissions from nuclear is at most equal to, and likely less than other renewables: https://www.ipcc.ch/site/assets/uploads/2018/02/ipcc_wg3_ar5...

Not to mention, there's enough accessible uranium to make concerns about the being "renewable" moot: https://www.forbes.com/sites/jamesconca/2016/07/01/uranium-s...

And the huge win provided by nuclear power is it's geographic independence and consistent output. Nuclear plants work regardless of wind speed, and give the same output in the Arctic circle as they do at the equator. And this output is consistent, it doesn't fluctuate with weather or day/night cycles. This eliminates the need for storage, which is something we don't currently have the capability to build at any substantial scale.

That's what people don't realize when they compare costs of nuclear vs solar + wind. The reality is it's costs of nuclear vs. costs of solar + wind + thousands of miles of HVDC lines to move energy from rural areas to population centers + massive amounts of grid storage to accommodate intermittent generation.
