However, workers at the Palo Verde nuclear plant in Arizona, about 50 miles (80 km) west of Phoenix, felt the 5.8-magnitude quake on Wednesday, the plant's owner told the U.S. Nuclear Regulatory Commission.
The earthquake did not register on the plant's seismic monitoring equipment.
One of my most heart-breaking episodes at the old company was to do with in-plant seismic monitoring. All the US plants have them, but they never work! There have been many earthquakes where they should have worked, but they didn't. I have some faith now that Diablo Canyon works.
We never had to install them in Canada, but non-working systems were the 'fashionable' thing for the rest of the world. Suddenly the cnsc (then aecb) felt naked when schmoozing with other regulators. "Quel horreur, yew don't have ze seismic monitors? We laugh at your small penis!"
So, they issued an order that all Candu plants must have in-plant seismic monitoring. Bruce nuclear promptly ignored them, so they hit at sappy OPG even harder! They knew who was more gutless than them!
When I heard of this, I thought 'OMG, these things never work, and we don't have any place for the wiring. We have to think of something new!" That's when my drift into depression started.
