Not what I have read. The quake was right at the maximum this plant was designed for. Plant was designed for 5.9 to 6.2. This was the strongest quake recorded in that area during the modern nuclear power plant era. So there must be at least some damage. Dominion itself states that these plants are built to the local requirements. And they have plants scattered around the east and mid-west.
6.2 is the “Safe Shutdown Earthquake”.
The “Design basis Earthquake” is probably around 7 point something. I’ve been out of the industry for 6 years, and I forget the exact numbers.
No, there doesn’t “have to be some damage”.
