$EP 2 31982 Docket Nos.: 50-424 and. 50-425 APPLICANT: GEORGIA POWER COMPANY FACILITY:
'ALVIN W. V0GTLE NUCLEAR PLANT, UNITS 1 AND 2
SUBJECT:
MEETING
SUMMARY
- MILLETT FAULT STUDY A meeting was held at the NRC headquarters in Bethesda, Maryland on September 14, 1982. The' applicant was represented by Georgia Power Company, Southern Company Services, Inc. and Bechtel Civil and Minerals, Inc. The NRC was represented by
-the Division of Engineering (GSB, HGEB) and Licensing (LB-1), NRR. A list of attendees is enclosed.
Georgia Power Company requested,this meeting to present its findings and conclusions in the Millett Fault Study, which is an extensive investigation program undertaken by the applicant in response to a U. S. Geological Survey Open File Report (82-156) that suggested the existence of a fault approximately
-seven miles southeast of the Yogtle facility near Waynesboro, Georgia.
During introductory remarks, the applicant emphasized that the purpose of the Millett Fault Study was to address the NRC's concern of whether or not a capable fault (one that has moved once within the last 35,000 years or has had multiple movements within the last 500,000 years) does indeed ' exist, not whether a fault does or does not exist. As an overview of the study, the applicant summarized its investigative program, followed by more detailed presentations and discussions of acquisition of data, drilling, field geological exploration, geophysical studies, groundwater evaluation, groundwater modeling, surface water hydrology and seismicity. The applicant concluded that none of its data
- and/or evaluations supported the existence of a capable fault. The final report will be submitted to the NRC in mid-October.
Following the applicant's presentation, the staff commented that the overall program was excellent in scope and detail. The staff agreed that the geological information, especially the stratigraphy as' determined from core borings and down-hole geophysical logging, appeared to support the absence of a capable fault. However, the staff suggested the applicant discuss in greater detail the anomaly near Fix 13 found in the seismic reflection records for the shallow reflector and review the evidence for the continuity of the deeper reflectors.

Georgia Power Company 2-The staff further requested that GPC:
(1) provide the seismic reflection lines from the Savannah River Project, (2) use overlays of simulated with measured data on the pieziometric contour maps, and (3) compare the the USGS's measured pieziometric contour maps f.or both aquifers with that produced by the applicant.
The staff noted that upon receipt of the final report to the Millett Fault Study it would undertake a very rigorous, independent review, including appropriate contacts with local experts. During and/or following this review, a site visit and meeting would be held to discuss further details of the study.
