Yeah, I'm surprised by how little attention this gets. A significant accident occurred that wasn't supposed to, and subsequent investigations showed that there were significant lapses, including from regulators. People can't be experts in nuclear plant design, construct, regulation, inspections, etc., so they need to be able to rely on the authorities in charge. When that trust is betrayed, it naturally has consequences. You can't just say to people, "Well, yeah, last time we told you to trust us we were completely wrong, but this time will be different!"
When problems happen that aren't supposed to happen, people are naturally going to be overly cautious and skeptical of future assurances. That's not an entirely unreasonable reaction.
Compare it to the damage of coal and it would not even show statistically.
