It’s really not, nuclear inherently requires extreme costs to operate. Compare costs vs coal which isn’t cost competitive these days. Nuclear inherently need a lot more effort refining fuel as you can’t just dig a shovel full of ore and burn it. Even after refining you can’t just dump fuel in, you need fuel assemblies. Nuclear must have a more complicated boiler setup with an extra coolant loop. You need shielding and equipment to move spent fuel and a spent fuel cooling pond. Insurance isn’t cheap when mistakes can cost hundreds of billions. Decommissioning could be a little cheaper with laxer standards, but it’s never going to be cheap. Etc etc.
Worse, all those capital costs mean you’re selling most of your output 24/7 at generally low wholesale spot prices unlike hydro, natural gas, or battery backed solar which can benefit from peak pricing.
That’s not regulations that’s just inherent requirements for the underlying technology. People talk about small modular reactors, but small modular reactors are only making heat they don’t actually drive costs down meaningfully. Similarly the vast majority of regulations come from lessons learned so yea they spend a lot of effort avoiding foreign materials falling into the spent fuel pool, but failing to do so can mean months of downtime and tens of millions in costs so there isn’t some opportunity to save money by avoiding that regulation.

I think we should target “risk parity with Gas” until climate change is under control.
And then you have bad faith actors.
No one would ever put graphite tips in the control rods to save some money, wouldn't they?
No one would station troops during war in a nuclear power plant, wouldn't they?
No one would use a nuclear power plant to breed material for nuclear bombs, wouldn't they?
Finally, no CxO would cheapen out in maintenance for short term gains then jump ship leaving a mess behind, right?
None of that has never ever happened, right?
This is also not as bad as people think. Chernobyl was bad, but the real effect on human health was shockingly small. Fukushima is almost as well-known, and its impact was negligible.
Even if we had ten times as many nuclear disasters - hell, even fifty times more - it would still be a cleaner source of energy than fossil fuels.
Meanwhile the amount of overregulation is extreme and often absurd. It's not a coincidence that most operational nuclear plants were built decades ago.
Was this not due to the expensive clean-up effort in each case respectively? Nuclear reactors may be a lot cleaner than fossil fuels operationally, and reducing their regulation to allow them to replace fossil fuels may well be cleaner on average. But if the once-in-a-blue-moon incident requires huge amounts of money in clean-up costs, then maybe those health and safety regulations would prove themselves cheaper in the long term.
Perhaps the real question is why we do not demand such stringent health and safety standards on fossil fuels, which are operationally dirty and prone to disaster.
IIRC Fukushima didn't actually leak enough radiation out to cause any significant environmental harm - quite possibly, most of the evacuations weren't even necessary, and the total toll among responders was only 25, with only 1 death.
Chernobyl was much worse, but other than responders and the high incidence rates of thyroid cancer in young children close to the disaster area, the total casualties were also lower than people assume. A lot of the early estimates were massively inflated.
Honestly it's quite possible that in both cases, we could have done much less relocation and evacuation, especially the fukushima response was largely driven by Japan's fear of nuclear technology.
