My understanding is that solar and wind are cheaper than nuclear even when accounting for storage.
That's before you get to the externalized costs, such as waste disposal and decomissioning.

In Ontario nuclear costs 10¢/kWh while wind costs 15¢ and solar 50¢ (Table 2):

And when wind goes to zero at night, then (natural/methane) gas generators are often spun up.

Which wind and solar also have. You may be able to extract some metals from solar panels, but turbine blades are not (AFAICT) recyclable.
This understanding is either based on geographically limited storage options (hydroelectric storage), or is incorrect. The amount of batteries required to even out intermittent sources is many times more than the amount of batteries produced. The cost of a 1 GWh facility is very different from a 1 TWh facility. The latter is 2x the amount of batteries produced worldwide each year. But it's only 2 hours of the USA's electricity consumption. That's how big of a mismatch there exists between battery supply and the demands of grid storage.

Waste disposal and decommissioning are already factored into nuclear power's cost. They have to pre-pay the cost of disposal and decommissioning.
Vogtle is $170-$180/MWh. https://www.powermag.com/blog/plant-vogtle-not-a-star-but-a-...
New solar is on average $40/MWh: https://emp.lbl.gov/sites/default/files/utility_scale_solar_...
Back in 2022 when prices were higher, NREL put batteries at $482/kWh:
https://www.nrel.gov/docs/fy23osti/85332.pdf
That's $87/MWh for storage, backing out the battery lifetime and round trip efficiency from the same report.
So depending on the time usage of electricity, the average solar+battery installation will have an averaging of $40/MWh and $127/Mwh electricity.
That's using old prices. It's cheaper today, and will get cheaper in the future.
And we're not even talking about electrifying other fossil fuels uses like heating, transportation, etc. That's going to make electricity demand even larger.
