Nuclear power is far simpler than people would intuitively believe. The nuclear reactor boils water at scale, the steam spins an electric generator via a steam turbine. The steam plant side of things is well understood technology, almost 170 years old at this point, nuclear power itself is about 70 years old. As technologies go, it's incredibly simple, and thus far less prone to error.
It is fearmongering to suggest or imply that there's catastrophe right around the corner of every nuclear reactor. This is just not so. It's not possible to have the kinds of nuclear disasters people are afraid of. Fatalities from nuclear power measure around 100 per thousand terawatt hours, far lower than any other power production source by orders of magnitude.
There is simply no evidence that nuclear power is dangerous, and a lot of evidence to suggest it is the safest, most effective power source we have created.
