Still not a reason to not build them, the entire point is for nuclear to handle the load when solar/wind can’t provide due to weather. Other renewables will still be producing the bulk of the power we need, but at night nuclear will be handling any demand spikes, each of them would greatly reduce the number of batteries required to satisfy the demand. They can stay until our solar output is so high we can just start electrolyzing water into hydrogen as energy storage.
