It’s really not even AN answer. It’s so expensive to build them, requires hoards of highly specialised people to build and operate, takes decades to build all the while were relying on fossil fuels still until it can generate power, has a bigger carbon impact than renewables due to massive amounts of concrete used in building decommission and waste storage, is more expensive per mw, and while on average safer than most types of power plant, if something unexpected happens shit goes extremely bad.

It just has way way way too many downsides compared to wind or solar or basically any other renewable to the point its just not really worth pursuing.
