Wasting money?
We already have stockpiles of fuel for latest generation nuke reactors in the form of "nuke waste". Building these plants kills two birds with one stone.
Nuke power is the safest form of power we've ever made. And they produce power WHEN it is needed. As for its cost, a good bit of it is in battling legal challenges from idiots who profess to be for "green" power. *** is green about clear cutting forests for solar farms? Or ginormous bird killers?
The idea that we can make enough batteries to power the grid is silly. Production of batteries is expensive and they are made using "precious" metals. There's a reason they're called precious.
Gravity storage is the only "green" form of storage. Trouble is, it only works in some places and on a large scale.
It will cost ~$120/MWh to turn that fuel into electricity while wind and solar are now as cheap as $20/MWh and costs are still trending down. Look at Vogtle and VC Summer. $40B down the tubes, not a kWh to show for it and they had no significant 'legal challenges' from any environmental groups. Why not use solar as covered parking or on roofs then put wind turbines in range land or far offshore? No trees are cut, no birds killed and we'd still have more energy than we could possibly use.
Who says we need only 'batteries'? We just need to 'time shift' demand or supply so they match. You can charge your EV or split water into H2 or pump water up a hill or compress air in huge underground salt caverns... etc, etc. What's silly is this notion that storing enough energy to last ~2 weeks is some insurmountable technical challenge. Our entire society has been running on mostly stored sunlight for nearly 100 years. I... I think we can find a way to store ~2 weeks worth.
AND... nuclear would require storage just as much if not more than wind or solar. Look at the South Texas Project. It costs ~$600M/yr to keep the plant operational and it doesn't much matter whether it produces 1GWh or 20,000GWh. So obviously no one is going to invest in a $30B asset unless it's used at ~100% 24/7/365. Demand isn't flat, what would increase supply when demand increases when it gets cold or hot? Not nuclear.
When supply < demand storage isn't useful for nuclear, wind or solar... they all just use gas turbines to load-follow but $/$ wind and solar displace >4x more gas than nuclear. Economics matters.
