I think your choice in phrasing speaks more to your emotional state than mine.
> No nuclear plant built since Chernobyl will have an incident as bad as Chernobyl.
You are discounting the fact that many of the nuclear reactors that remain in operation today were designed decades ago and were built decades ago.
Of course newer nuclear technology is safer -- I don't think anyone would ever disagree with that. But we are considering the safety of nuclear power as it exists today. Why would we omit nuclear reactors that are currently in operation today (and will continue to be in operation for quite some time) from the discussion?
