I’m not sure why you seem to think nuclear and renewables are competing, but you’re just objectively wrong. Non-consistent and on-demand power generation literally go hand-in-hand. There are coal power plants that rarely turn on because they are only turned on when the grid needs to offset peaks, something that cannot be done with current renewables, even with your incredibly expensive batteries (which are mostly going into EVs anyway, and thus are a moot point.

Additionally, California is ideal for solar panels, but I assume you haven’t put even an ounce of thought into how New York or Chicago will handle it, have you?
