I recall that other power plants such as thermal power is still required to provide “inertia” for the whole system, as solar fluctuates a lot. The recent Spain-Portugal outage showed that there is not enough inertia in the system.

I don’t really understand inertia in power plants but I wonder if it helps to push nuclear as primary and solar as secondary?

The best way of doing things changes as market prices for the various options change. At the moment we mostly have renewables, wind and solar backed up by natural gas powered plants that can increase and decrease power rapidly. As time goes on and batteries and solar get cheaper things will probably move more to those. Nuclear is good for constant power but expensive.
