Subject:

Information on North Anna and Earthquakes The staff was asked to identify which nuclear power plants had experienced earthquakes exceeding the OBE/SSE. The staff identified two (besides North Anna):

• VC Summer - Experienced an earthquake in 1979 exceeding its OBE. This was prior to the plant being licensed.

° Perry - Experienced an earthquake in 1986 exceeding its OBE and SSE. This was prior to the plant being licensed.

I'm passing this on for information. If you have any questions, please let me know.
