Well...I was saying that when an uncontrolled reaction (atomic explosion) is the goal, no controls are applied but rather the opposite (compression to critical mass).
The chief danger from a nuclear reactor has always been not an atomic explosion, but uncontrolled release of radioactive materials (as dramatized by Garrett Morris).
IMO the best safety measure is to not build a reactor over a tectonic fault.
I don’t think what is happening today has anything to do with earthquakes.
