I don't buy into the "red tape" argument. For me it's all due to a lack of a business case. I think building (LWR) nuclear plants is just freaking expensive, has always been freaking expensive, was bankrolled for a while by governments because they thought it would get cheaper, and then largely abandoned in most countries when it proved to be an engineering dead end.
Here's an MIT study that dug into the reasons behind high nuclear construction cost. They found that regulatory burdens were only responsible for 30% of cost increases. Most of the cost overruns were because of needing to adapt the design of the nuclear plant to the site.

Now, you can criticize the methodology of that study, but then you have to bring your own study that shows precisely which regulatory burdens are causing these cost overruns, and which of those are in excess. Is it in excess that we have strict workplace safety regulation now? Is it in excess that we demand reactor containment vessels to prevent meltdowns from contaminating ground water supplies? In order to make a good red tape argument I expect detail in what is excess regulation, and I've never seen that.
Besides, if "red tape" and fossil industry marketing was really the cause of unpopularity, and the business case for nuclear was real when installing plants at scale, you would see Russia and China have the majority of their electricity production from nuclear power.
- Russia is the most pro-nuclear country in the world, and even they didn't get past 20% of electricity share. They claim levelized cost for nuclear on the order of that of solar and wind, but I am very skeptical of that number, and anyone who knows anything about the Russian government's relation to the truth will understand why. When they build nuclear plants in other countries (e.g. the bangladesh project) they are not that cheap.
- China sits at low single digit percentages of nuclear share, with a levelized cost that is significantly higher than Russia's and well above that of solar and wind. While they're planning to grow the nuclear share they assume it will be based on new nuclear technology that changes the business case.
Both Russia and China can rely on cheap skilled labor to bring down costs, a luxury western countries do not have.
And this is ultimately the issue: the nuclear industry has been promising designs that bring down costs for over half a century, and they have never delivered on that promise. It's all smoke and mirrors distracting from the fact that building nuclear plants is inherently freaking expensive. Maybe AI can help us design better and cheaper nuclear power plants, but as of today there is no proven nuclear plant design that is economical to build, and that is ultimately why you see so little new nuclear plant construction in the west.
