Chernobyl isn't what happens when a made-to-code Nuclear Power Plant goes boof. With any modern design the possibility of a NPP spreading contaminant over an area of any significance is effectively zilch. Even if there is an issue, you end up like Fukishima and there's a whole 1% chance of increased cancer, and even that wasn't due to the NPP not doing it's job correctly, but due to the designers of the plant putting shit where it didn't belong in the first place.

Nuclear is cleaner and safer then any other reasonable power source we can imagine, outside of space giga-structures. It's literally the only way we'll be able to keep up the energy demand AND safety needs in the next century.

The only thing to fear is fear itself.
