A single new reactor takes decades to build and costs billions. Investing in solar, wind, the grid and storage instead will generate more energy, faster, and for less.
It's not "instead of".
You're supposed to run nuclear along side renewables. Opposed to running fossile fuels alongside renewables. Either way, something has be running besides renewables.
But that's literally what you're gonna have to do for 20+ years if you decide to go both ways and also build new nuclear plants. Put all your budget into renewables at once and you instantly cut down on the fossil fuel you'd otherwise burn while waiting for your reactor to go online, all while you're saving money from the cheap energy yield which you can reinvest into more renewables or storage R&D to eventually overcome the requirement to run something alongside it.
No 100% renewables is viable. You don't need anything running beside it.
