I think it is unfair to specify safe here, as probably all nuclear powerplants are considered safe until they are not, including Fukushima. But plenty of European countries are either building or planing nuclear new nuclear power reactors, and Finland just opened a new reactor in 2023.

But the simple matter is thought that the economics of nuclear power simply are not delivering. They are expensive and slow to build, while at the same time wind (particularly off shore wind) and solar are getting cheaper and easier to build every year (or month even). Germany also stands out as a success story of nuclear phase-out, that by replacing these expensive to run nuclear power plant has offered the economic wiggle room to phase in renewables a lot faster then otherwise.
