I disagree. There have been lots of low-level safety violations, and it's easy to find examples of chronic mismanagement. By 'spotty' I mean lots of small flaws, a few big ones here and there. Certainly, it has a good low ratio of deaths per megawatt of power generated, but such metrics are not the whole story.
I'm very pro-nuclear, but don't think there's an mileage in blowing off safety concerns.
This is so incredibly false it's on par with stating "commercial aviation has a spotty safety record overall".
