> Nuclear cost: ~6k per kW baseload > Solar + battery cost: ~7.6k per kW baseload (~4k/kW generation, ~3.6k/kW storage) So nuclear is cheaper than solar + sto

  China, South Korea are $2K-2.5K per kilowatt of baseload. A Nuclear kilowatt generates 70-95% of the time. A solar kilowatt generates 10-20% of the time. A Gigawatt of solar generates 1 Terawatt hour per year. A gigawatt of nuclear generates 6 to 8 terawatt hours per year. So nuclear generates an average of 7 times more. Solar lasts 15 years. Nuclear lasts 40-80 years. Solar needs to be rebuilt 3 to 5 times versus nuclear. There is no supply chain for matching battery storage at scale. They are just starting to build batteries for cars at the 200 gigawatt-hour levels. Solar and wind in California and many other places has only 10% of the generation during winter. There is no 90-day power storage and building one would be insanely expensive. You pay for electricity by the kilowatt-hour.
