Transmission costs will require more than "wiggle room" if you are sending power from some cornfield in middle America to Seattle.
Also a big question in my mind is "where can the price go from here". I don't imagine there is a huge amount of room left for optimization of solar, where as with nuclear I think almost everyone agrees that it is about as expensive as it could be. There is infinite room to improve the economies of scale and unit economics of nuclear; not so much for solar.
Offshore wind is more like $70, but also has double the capacity factor, so requires less matching storage.
We've been told for about 3 decades that any day soon microreactors/thorium/fusion will lead to cheaper, safer nuclear power and no doubt for the next 3 decades some people will continue to believe.
To be more concrete: the first chart from this report[1] is showing "Solar PV + Storage—Utility" at $50-130 (mid-range: $90) and "U.S. Nuclear" at $141-220 (mid-range: $180).
I don't think we've had serious capitalized work on micro-reactors for 3 decades, it's a much more recent phenomenon. And China (who is massively outperforming the US in solar deployment) is also deploying Thorium reactors. Kinda strange for them to do that since they're so good at solar and nuclear is such a lost cause, esp since Thorium reactors are generally worse for the military/weapons case (which you claim is the only reason nuclear energy programs exist).

With a price difference of 5x there is more than a little wiggle room to price in storage and transmission costs and still end up way cheaper.
That is how every kilowatt hour generated with solar and wind and stored with power2gas (the most expensive form of storage) still ends up being cheaper than nuclear power generated on a sunny, windy day.
Nuclear power survives exclusively because it integrates with the military industrial complex. Thats why it gets deluged with lavish subsidies, that's most governments only want a few and that's why the governments who build them either have a bomb or want the ability to build one in a hurry (e.g. Iran who joined this club a long time ago or Poland who joined recently).
