The batteries need to be replaced every 5 to 10 years depending on how many cycles they can endure. By comparison, the AP-1000 is rated to last 60 years. Furthermore you're being very pessimistic with the $20 billion dollar cost estimate for the AP1000. Plants with equivalent output have been built for less than $10 billion. When you include the cost of storage, solar and wind is still enormously more expensive than nuclear. The reality is that we don't event know what storage at this scale would even look like. It would take 800 years of global battery production at the current production rates to reach the 3 weeks of energy storage required to decarbonize the US with renewables. And that's with the infeasible idea we're dedicating 100% of batteries to grid storage: no EVs, no smartphones, all grid storage. And again, this is just for the US's storage needs. Forget cost, energy storage at this scale isn't event possible with one current levels of technology.
