The fact that the US market structure and regulators led to unsafe and unprofitable power plants has little to do with the underlying technology.
France: https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan... "A third reactor at the site, an EPR unit, began construction in 2007 with its commercial introduction scheduled for 2012. As of 2019 the project is three times over budget and years behind schedule."
China: https://en.wikipedia.org/wiki/Nuclear_power_in_China "Nuclear power contributed 4.2% of the total Chinese electricity production in 2018" "China was planning to have 58 GW of capacity by 2020.[3] However, few plants have commenced construction since 2015, and it is now unlikely that this target will be met."
It seems reality doesn't match your beliefs.
Between 1975 and 1988 the world added 250 GW of carbon-free nuclear generation. That's 20 GWe/year.

France is about 75% nuclear, Germany is about 10%
French electricity is about 2x cheaper than German, and they have much lower emissions.
Since Germany has shut down nuclear plants in favor of renewables, it has been forced to increase coal and has actually increased total emissions and accident deaths significantly.
Ontario, Canada is about 60% nuclear and its electricity prices off-peak are about 10x lower than German, on-peak about 5x lower.
Nuclear is the safest, most efficient, and more reliable energy source all nations that have it and those who have more have more affordable energy. Reality has shown this consistently for now almost 80 years.
The blaming of regulators is mere excuse making.
