Is nuclear power safe?

Given that all credible reports have radioactivity levels at and beyond the site line at the order of magnitude of what is normally experienced in a freshly painted room, or lower (with the exception of readily identifiable and containable "Hot Spots"); and that Gundersen has a long history of crying "The Sky is falling! The Sky is falling!" for reasons of profit seeking and personal ideology, I will need something a little more substantial than "Elevated levels of radiation are being reported by Japanese BLOGGERS all over eastern Japan."
