MAR I S 1982 Docket Ho.:
50-39S ftEMORANDUM FOR: Atonic Safety and Licensing Board for Virgil C. Sumner Nuclear Station, Unit No.1 FR0!!:
Robert L. Tedesco, Assistant Director for Licensing, DL L
SUBJECT:
BOARD HOTIFICATION - POSSIBLE CllANGE OF POSITION BY U. S.
GEOLOGICAL SURVEY OH THE LOCALIZATION OF THE 1886 CHARLESTON, S. C. EARTHQUAKE (BH HO. 82-22)
The Extreme External Phenonena Subconnittee of the Advisory Committee on Reactor Safeguards (ACRS) sponsored a two day nesting held on January 28-29, 1982 to hear presentations by prominent earth scientists throughout the U. S. who are engaged in seismic and geologic research. During the seminar much time was spent discussing the geology and seismicity of the Charleston, South Carolina region.
In past licensing decisions, the HRC staff has assuned, based primarily on reconrendations from the U. S. Geological Survey (USGS), that the relatively high seismicity in the Charleston area, including the 1886 Intensity X Charleston Earthquake would not recur anywhere but in the Charleston area.
~
Geologic and seisnic research, funded by the NRC and carried out by the USGS, has been ongoing in the Charleston area since 1973.
In reviewing the Virgil C.
~
Sumer OL-SAR, the HRC staff and the USGS considered all of the infomation available at that time and reaffirmed our original CP-SER conclusion.
No significant new infornation was presented at the January 28-29 ACRS Subconmittee meeting that was not considered in our evaluation of the Virgil C. Sunner Nuclear Station, but the USGS stated that it was reviewing its position on the Charleston earthquake. The USGS review could result in one of the following three positions or some other alternative:
(1) A Charleston-type event could only occur in the Charleston area - a reconfirmation of their past position; (2) A Charleston-type event is more likely to occur at Charleston than elsewhere, but is' not unique to the Charleston area; (3) A Charleston-type event could occur throughout the castern seaboarc' as there is nothing unique to the Charleston area.
The NRC staff continues to support its position stated in the Virgil-C. Sunner OL-SER pending any new position statenent by the USGS, which we expect to receive in the future.
