Well, who would have thunk? Expensive nuclear energy is not viable, if holding a blue sheet of sand towards the sky produces power for like half the price.

If it was a matter of half the price then nuclear would be the clear winner. Paying double to get stable power rather than variable power is currently a clear win.
Nuclear has a lot of baggage on top of being more costly (eg public fears, taking a lot longer to get running, building up big debts before producing anything, and having a higher cost risk due to such limited recent production), if it was just a simple “pay twice the price and you never need to worry about the grid scale storage” then nuclear would be everywhere.
It's been a while since I looked it up, but back then the projected price of SMR energy was about double the cost of current solar.
I'm not sure, if that changed much over the last month.
Anyway, wind, solar and hydro combined can produce energy pretty inexpensively. The power grid isn't exactly simple with nuclear reactors either, so it's not like you're winning that much from this perceived reduction of complexity.
Unfortunately we still need tunable baseline power in order to keep current, voltage, and frequency within the grid's margin of error. Our options for that are: situationally available (and often environmentally problematic) hydro, fossil fuels, nuclear, and/or giant toxic/fire-prone battery banks.
You forgot hydrogen, saltwater batteries, proper grids, biogas, etc.
If you'd use nuclear power like that, you'd drive up the costs even more, because it's just not very viable to compete with solar and wind during the day. Better to just invest in proper storage solutions.
