Humongous batteries or humongous nuclear reactor? Which will be cheaper? Especially, what will be cheaper in 10 years? Which will be online faster? As in, can be scaled out in 3-5 years? With forthcoming 200 wh/kg LFP / LMFP, 140 wh/kg sodium ion, and various other schemes, I will heavily bet on batteries + solar / wind beating out nuclear. I don't know if you're engaging in FUD based on cobalt and nickel chemistries, or just are ignorant of the forthcoming Gotion/CATL production lines for high density LFP and sodium ion chemistries. Those aren't resource limited, they just need to build the factories, and factories are a lot better than nuclear power plants in timescale. PLUS, storage + solar can be distributed to the home to reduce the amount the grid needs to move from a centralized generator, make the grid and homes much more resilient, and function as a backup battery store to grid storage. I never see hydro listed on LCOE charts. I'm going to assume it's at the scale of nuclear which is already not competitive. Hydro is actually the best grid storage if you have a mountain and two big lakes or some similar setup. As I understand it, the efficiency is 90% pumping and then getting it back.
