How much more advanced and safer is a nuclear power plant built today compared to one built in 1986?

I was recently thinking about how much better computers have gotten in the past few decades, and wondered if nuclear power plants had improved along the same rate of improvement. I chose 1986 because of the Chernobyl incident, but I'm kind of talking about all types of nuclear power not just the Chernobyl type of reactor. (Also I'm surprised there isn't a Nuclear flair)

Engineering?

Chernobyl was based on a stupid reactor type that is not built any more. In addition the operators were actively overriding multiple safety rules and mechanisms - something that won't happen any more because we have an example how that can end. Another accident like Fukushima is not completely impossible if something really bad happens (like one of the most violent earthquakes and tsunamis in recorded history). Chernobyl will stay a unique event.

It is very difficult and problematic to assign numbers to big accidents. They are so rare that there is not enough data to determine it experimentally.
