Also when comparing nuclear to “renewable” energy, you are really comparing distributed low density investments with monolithic ones. Nuclear is 1e6 the energy density of chemical reactions. And wind/solar is basically heat exchangers positioned 8 light minutes from the nuclear reactor. The Sun incidentally, is just as renewable as that Uranium we are discussing.
What really boggles my physicist brain is how we expect a bunch of volatile solar and wind stitched together with fragile infrastructure and lithium piles to ever become a stable base load alternative. I put my hope on the Engineers knowing better than me :)
I don't work in this field, but I'd have a bunch of basic assumption you could dismantle:
1. We need a solid power grid, anyway, you know, for transporting electricity where it's needed. So shouldn't that stitching be quite solid anyway? Also, at a national level, I'd imagine solar and wind probably have rather solid statistical patterns, and those random factors can be abstracted away to a degree (the whole "what happens when the wind is not blowing?" - kind of hard to have the wind stop blowing all over 300k sqkm, all at once :-) ).
2. Once that power grid is solid, does it matter how small and distributed those solar and wind patches are?
3. I don't think Lithium-Ion is the only/main energy storage tech being investigated/invested in for grid purposes. And why couldn't it become a solid alternative for base load? Are base load-capacity energy storage facilities not competitive with gas/nuclear/coal power plants, factoring in pollution or other risks?
Networks offer the best return on investment when they are fully utilized not sitting idle.

> It turns out that the main reason for spiraling nuclear plant construction bills is soft costs, the indirect expenses related to activities such as engineering design, purchasing, planning, scheduling and — ironically — estimating and cost control.
> These indirect expenses accounted for 72 percent of the increase seen in reactor construction costs between 1976 and 1987, a period in which the amount of money needed for containment buildings rose by almost 118 percent.
Added to which, being a baseload power source is not nearly as useful as being dispatchable (like hydro and natural gas are), and it's insanely capital intensive (which leads to cost overruns - see hinkley point c, corruption & fat profit margins).
It's got real lobbying muscle though, especially from defense and military.
"Dispatchable plants have varying startup times. The fastest plants to dispatch are hydroelectric power plants and natural gas power plants. For example, the 1,728 MW Dinorwig pumped storage power plant can reach full output in 16 seconds.[4] Although theoretically dispatchable, coal and nuclear thermal plants are designed to run as base load power plants and may take hours or sometimes days to cycle off and then back on again."
