    "Lift this heavy rod exactly four inches or everyone in the vicinity dies a gruesome death" is peak 1960s nuclear safety design.  Right up there with "The tip of this screwdriver is the only thing keeping everyone in the room from receiving a lethal dose of radiation instantly".

    "My radiation detector must be broken." seems to be a common reaction during nuclear accidents. I would trust the hell out of mine.

    Thing I've learned from these incidents is NEVER think your radiation detectors are broken or faulty!

    "But instead of the intended four inches, he for whatever reason, yanked it twenty inches....." game over

    &quot;Essentially we did a huge amount of research to find all the most dangerous short cuts and points of failure, and we designed the reactor hitting all of them&quot; <br><br>Good work lads

    Sounds legitimately like they expected the rod to stick and gave it the extra oomph right off the bat, and it came more freely than intended.

    Gotta say, pulling think rod up 20&quot; not 4&quot; sounds wholly explicable if they were sticking. Can you imagine it sticking so you are yanking it harder and harder again, it suddenly frees up... Woosh, 20&quot; sounds an entirely predictable result.

    I wonder if the previous 2 false alarms weren&apos;t false alarms

    Whoever designed this really did a poor job or were designing it to fail. I mean, &nbsp;if you pull something 16 inches too far and it explodes within 4ms that sounds more like a bomb to me than a functioning power reactor.

    The setup should have made it physically impossible to lift the rod beyond 4 inches.
