There is even more concrete and steel, and copper, and electronics, and water - used in nuclear power plants. It takes a lot of energy to mine and refine, and enrich, and transport nuclear fuel.

It takes 10-20 YEARS to build a nuclear power plant. The spent nuclear fuel has to sit in pools of water for a decade or more - and the water has to be pumped, and then processed afterward; because it is contaminated and radioactive.

A lot of energy is used to decommission a nuclear power plant - and it will probably take another 10-20 years to do this. It will take a lot of energy and steel and concrete to build the dry casks - which last only 100 years. Rinse and repeat, for a very long time.

Wind power uses no fuel. So, it has a much lower energy overhead, and the foundations can be reused.
