Surely the real sweet spot is diversity? Solar for when it's sunny (which is more often than many think in lots of parts of the UK, especially SE England), wind (reliable most of the year in other parts of the UK), tidal/wave/hydro, etc.
At least for nuclear, no. The cost is overwhelmingly in the construction rather than the operation so it makes sense to run it all the time. With diverse green sources while their fluctuations are less correlated than just adding more solar you still have the potential for all of them to have a lull at the same time.
