A MW of nuke capacity is not replaced by a MW of solar or wind. New generation is much cheaper, but only because we are neglecting the parts of it that are hard and expensive - storage and transmission. Renewables without those things are worse than nuke - they are undispatchable like nuke and they are uncontrollably variable. We should build more renewables, but it is essential that we either tolerate intermittent system outages or massively improve transmission and storage, the generation is the least important part right now .

That's not correct, including storage with solar is still cheaper than nuclear. That's not measuring the cost by MW or GW, it's by measuring the cost of kWh, or the levelized avoided cost of energy, or the whatever metric you want.

And solar has the benefit of being able to avoid a good chunk of transmission by placing it at the site of use, so including transmission costs can only be to the benefit of solar.
