I suspect the specific design flaw they&#x27;re referring to is the graphite tips of the control rods, and the fact that, for the first few seconds of a SCRAM, the reaction rate is <i>increased</i>. And the control rods jammed in that position.<p>Yes, there was serious human failure in Chernobyl. But when the maximum emergency &quot;oh shit&quot; safety feature works by making things even more unsafe before shutting stuff down, that is the sort of design flaw that probably should be criminal.
