      But that’s just the generated per kwh cost, not taking into account when the energy is generated. To compare a full renewables grid to a renewables nuclear mixed grid you need to take into account massive energy storage systems and their inefficiencies and possible material shortages. We can’t just compare the currently favorable cost per kwh without taking into account problems as we scale into less reliable energy sources.

        You will need long term storage in both cases. Nuclear can’t act as a peaker because you can’t quickly ramp up or down the generation. Nuclear can only perform as baseload which, in theory, could be provided by a renewable energy mix if the install base is high enough.

        I don’t disagree with your point that it isn’t a simple direct comparison but any sensible energy mix will still require storage. I find it difficult to see the economic case for nuclear if renewables can be installed in sufficient quantities, given that nuclear is roughly 4 times as expensive as solar and wind.

          Nuclear can only perform as baseload

          That’s only true for NPPs built decades ago. Modern designs can also do load-following power. For peaks you have renewables, of course, they complement each other. Diversity makes a healthy grid.

            Niclear has high investment cost and very low production cost which incentivises runnig at max output for as long as possible. This might block out renewables from the grid if their production cost is higher and make it less profitable to build them. So its really not a Symbiosis between nuclear and regenerative
