Comparing nuclear (available 24/7) with solar without storage (available only in during the day only in some seasons) seems tricky - of course the solar will be cheaper. It doesn't cover all the need though. And storage is mostly unsolved problem at scale. Nobody in the world ever built GWh size battery. So supporting solar means you're either suggesting going with stuff that doesn't exist (and might as well go with fusion then, right?) or you're basically supporting fossil fuels.
