The worst case of nuclear, it is worse than the worst case of solar/wind. So even if it were rational for humanity, it might not be rational for a country.
I'm having trouble picturing how it is safer than solar though.
The statistics wrap rooftop solar into the “solar” mix so all those DIY/fly-by-night installers who don’t use safety equipment while working at heights and end up killings themselves make solar by far the deadliest energy source in terms of deaths per MW capacity installed.
