This is totally following the Perry nuclear plant script. As we recall, Perry was exposed to the exact same ground motions, but was in hot testing for startup, rather than actually operating. There were many lessons to be learned there, all of which fell off the nuclear duck's back.
We wrote an opinion piece that nuclear plants should beef up their seismic instrumentation to avoid this in the future. Boy, did I get into trouble for that, with the evil ones.
We wait and see how this plays out.
