Nuclear has several major cost problems if it's own. Insuring against a major accident is prohibitively expensive, the kind of inspection+maintenance regime that's necessary for safety isn't amenable to cost reductions. The list goes on. Basically:
Nuclear isn't similar to the things that grow cheaper as the operators gain experience.
Much if fhe inspections and standards aren't "necessary for safety" but the direct product of paranoia and lobbying. Nuclear is brutally overregulated, far, far beyond what's necessary to ensure safety, and that's where most costs come from.

Is this really true? We seem to have a pretty large disaster perhaps every 15-20 years (3 mile island, Chernobyl, Fukushima), which makes me think that it is either correctly- or under- regulated. Of course coal and oil are worse, but that’s not exactly a high bar…
In Fukushima zero people died from radiation. If we regulated everything to a similar point (cars, planes, fossils), you'll start living like a monk. Fossils aren't just worse but orders of magnitude worse
In France after Fukushima nuclear plants that are 500 km inland had to be safeguarded against the risk of a tsunami.

Fukushima killled a couple of people? More died that day from car crashes.

It is what we want to replace with nuclear power, so that's exactly the bar we should jump over. So let's say it: all of these disasters did not cause even 1/1000 as many deaths as coal power plants.

Your 3 examples were all different regulatory regimes.
That myth keeps persisting. In reality per $ of the project wind farms face significantly higher regulatory costs in many countries. Nuclear power operators also managed to get regulations on the turbines dropped compared to coal plants (in Germany IIRC).
In reality we see it time and time again, the larger a project (and that applies to pretty much all infrastructure) the easier it is for the operator to get regulations loosened, because of the large amount of money involved, they tend to have much more leverage over politicians.
Then why is the insurance for every single reactor public sector based?
Possibly because if there's a big accident, everybody in the region who gets cancer will sue, even if there's no detectable change to cancer rates.

No,
The reason that constant inspections are need is because radiation weakens everything. Since nothing is immune, everything can break prematurely and so everything must be inspected.
Fukushima and Chornobyl happened directly for a lack of paranoia, regulation and lobbing. I hope that we don't commit the same mistake again.
Fukushima happened in a highly regulated (and correspondingly expensive) environment. Improving the regulation doesn't necessarily just mean adding more of it or tightening targets far beyond any useful range. Also, arguably the evacuations as a response to Fukushima caused more harm than the radiation would have, an example of paranoia as opposed to effective regulation.
(Chernobyl also happened because of paranoia but that was largely the Soviet's obsession with saving face to the point of hiding a design flaw from the operators).
Though, I will push back on the idea that this is exclusively why it's so expensive: Nuclear has plenty of other issues with cost beyond excessive safety targets.

The human impact of those is a fraction of fossil-fuels. So it’s not fair to judge nuclear for being expensive if we don’t hold other fuels to similarly rigorous standards

Not GP, but plutonium is overhyped in how scary it is.
Don't get me wrong, it's super deadly, but there are loads of toxins that are more deadly than plutonium. And while its radioactivity is seen as ultra scary, it's actually pretty nice, because you can at least detect it. Harder than beta or gamma, but still, it announces its presence.
How I wish I had a magic wand (spectrometer) that I could wave over my food to see if cyanide, ricin, mercury, or lead were there.

See nuclear topic, scroll just like 2 turns to see once again someone claiming nuclear is the one technology in all of history that doesn't improve with technology.
> Insuring against a major accident is prohibitively expensive
Isn't this the thing where you require something in one case but not the others?
If every oil drilling operation had to carry enough insurance to cover Deepwater Horizon and every hydroelectric dam had to carry a policy large enough for Banqiao and every solar panel factory had to insure against leaving Superfund sites that leak into the groundwater in some of the most expensive real estate in Silicon Valley then they'd be in trouble too.
> the kind of inspection+maintenance regime that's necessary for safety isn't amenable to cost reductions.
People often say things like this and then if you actually have someone go through the existing process you find out that more than half of the labor is going to inspect things that aren't actually safety-related, or some corruption is involved which is quadrupling the cost because the contractor bribed a politician to make use of their services required by law or create artificial scarcity for something which is actually important but shouldn't cost as much as it does.
Insuring is dirt cheap. You don't insure against any nonsense but against most probable one.
Nuclear gets cheaper if you have several units built in same place and if you increase CF with various methods, incl higher enriched fuel
