==SUMMARY==
0 . F MEETING HEl.D AT USGS -
On March 1,1982, Harold Denton, Jim Knight and I met with Dallas Peck, .'
Director, U.S. Geological Survey (USGS) and memb.ers of his staff. I' requested this meeting in a letter of December 14, 1981 to Dr. Peck for the purpose of discussing the continuing need for review assistance from the USGS and to assure continued coordination of review schedules
                 ~
necessary to meet plant licensing requirements. A list of attendees is attached.
The interaction between'NRC and USGS continues to be effective.-
Con-duct of a comprehensive safety review requires input from USGS~
research in both specific site and regional matters as wel.1 as topical            .                .
issues such as earthquake hazard estimation. Close coordination between             -
                   . the USGS and NRC staffs assure that pertinent information flowi.ng from                         -
USGS research programs is brought into NRC safety evaluations in a timely fashion. The particularly rapid development of inf'ormation in the area of strong ground motion that has occurred in the past few years has ma.de '
this coordination all the more necessary.
Better understanding of the geologic basis for certain eastern seismic events such as the New Madrid and Charleston earthquake has been gained                           -
through USGS research. The geological process occurring in the New Madrid region is now considered to be well understood. We spent considerable tim'e on the Charleston issue. The geologic features related to the Charleston, So'uth' Carolina event under current hypoth-esis may not be unique to the Charleston area. The cumulative displace-
                           ~
ments over geologic time are small on these features. In light of todaf's-
   !                     knowledge, it may not be appropriate to fix a single location for the
   '                     Charleston event but to express the probability, albeit low of such an earthquake occurring anywhere in a large region. Probabilistic' charac-terizations may also- be more appropriate for some western sites of complex geology such as the Hanford, Washington ' area. The USGS and NRC staffs will work' closely on these developments to assure effective communication.

Other parts of interest resulting from the meeting included:
                                          -     A briefing on the proposed. safety. goals for nuclear power plants would be useful as one means of assisting communication between the USGS and NRC staffs with r,egard to the evaluation and use of probabilistic methods in seismic hazard and safety evaluation.
This briefing will be arranged at the earliest opportunity.                               -
                                            -     Probabilistic characterization of seismic activity may appear                   The to conflict with the approach of Appendix- A to 10 CFR 100.

Finally, Dr. Peck and Jim Devine stressed a point that they wished us' to bring to the ASLB Panel's attention. The duration and scope of the NRC hearing process often makes USGS planning for NRC assistance difficult.
