Citation needed. Afaik nuclear is not expensive because of it's ongoing resource need but because of its construction (and also regulatory) costs.

I'm not writing a wikipedia article. If you want to disprove, feel free to add you own sources and knowledge. I legitimately would be really interested to read how Solar and Wind takes less space, cement and metal than nuclear per WH produced.

You still don't understand that there is a difference between peak capacity and total emissions, right? And that you can replace plenty of total emissions with completely "uncontrollable" energy resources?

Let's say you already have controllable nuclear power and you want to switch while maintaining capacity, best options seems to be either storage + renewable or fossil. Actual production on a given period is an orthogonal problem, we are discussing controllable capacity because you don't want population and industry to suffer and you plan carefully.
Now replacing nuclear capacity, with whatever else, in order to reduce total emissions doesn't make sense, you are doing this for a totally different purpose. Replacing nuclear capacity by investing in new fossil capacity, in order to reduce total emissions, doesn't sound that smart.
Sir, your response is not very civilised!
Short term, if you had 10GW of controllable nuclear, you will have to replace it with 10GW of another controllable source. As long as you don't have huge energy storage, replacing reliable and controllable energy source with something not controllable is pure fantasy. In our world this is typically replaced by Gas or Coal. Maybe in a future world we'll have plans to replace one controllable power plant with renewable and storage.
Solar/wind is far from ideal, requiring more cement, metal and other materials but also more space than other traditional concentred power sources and by multiple orders of magnitude. You also have to take into account new infrastructures for energy storage.
