The worst ever nuclear power accident occurred at Chernobyl in the Ukraine in 1986, when most of an operating reactor was spread around the surrounding countryside and a plume of gaseous activity reached many other European countries. However this was one of a kind, fortunately, nothing similar has ever happened elsewhere, and the PWR and BWR units used in the US and most of the world have been very safe and reliable. Nothing similar could happen unless there was a major disruptive failure of a pressure vessel, and this is judged to be an incredible accident, taking the level of incredibility at once in a million years, per reactor.

Yes, a relatively large number of time ranging in how serious they have been. The worst to date has been Chernobyl resulting in a full scale reactor meltdown.
