Post the scenario where renewables would back up nuclear .
l've suggested the morning and afternoon peaks that we see each day .
Show us when the renewables would come and go off. Explain how that works . We know how gas peakers work. We know how big batteries work. We know how Snowy hydro varies it's output.
Show us how you would do that with solar and wind .
Btw . Why aren't we using renewables to back up coal during peaks now ?
