An NPP doesn't benefit that much from a battery. They're generally used to provide base load which fits their constant supply profile. Peaks and quick variations can be supplied by more flexible renewables together with a battery to buffer it.
Pumped hydro has been built to work with Nuclear in the past precisely because the flat output of nuclear doesn't actually fit the shape of demand.
Of course these days, you can feed the pumped hydro or batteries with much cheaper renewables.
