Why not both ?
I don't think I've seen any long term scenario with only nuclear and no solar energy.
On the other hand adding a bit of nuclear in the mix can really help to reduce the amount of solar panel needed.
The simulation done for France show that 13% of nuclear in the grid can roughly divide by almost two the amount of solar, batteries and thermal power station needed compared to a 100% renewables energies simulation.

The amount of Batterie and Solar between M0 (100% renewable) and M23 (87 % renewable and 13 % nuclear with a Fokus on solar over Wind) is almost the same tough.
Where do you see a dividig by two?
M0 uses 26GW of batteries and 208GW of solar panels.
M23 uses 13GW of batteries and 125GW of solar panels.
