NRC STAFF TESTIMONY OF DAVID B. SLEMMONS Q.1.
Please state your name and present occupation.
A.1.
fly name is David Burton Slemmons.
I am Professor of Geology and Geophysics, in the Department of Geological Sciences, !!ackay School of flines, University of fievada, Reno, flevada.
I am also a consulting geologist and geological engineer.
Q.2.
Please summarize your educational background and relevant work experience.
A.2.
I received my B.S. in Economic Geology and Ph.D. in Geology. from the University of California in Berkeley. My teaching specialties have I
included field geology, petrology and petrography, environmental geology, engineering geology and earthquake engineering. My research and work experience included work on active fault studies and seismic hazard and risk analysis. My consultation includes work with industry, engineering l
l 8105050684 t
e,
i and geotechnical firms, utilities, and governmental agencies. My qualifi-cations and experience is shown on,my attached list of qualifications, experience and publications.
4 Q.3.
Please describe the scope of your participation in the review of the GETR for this proceeding.
A.3.
My participation in the review of the GETR has been as a con-tractor and personal services consultant to the Geosciences Branch of the U.S. Nuclear Regulatory Commission. The primary purpose of my review has been to provide an assessment of the potential for surface faulting at or near GETR that is independent of that of the U.S. Geological Survey and the NRC Staff.
My review includes field examinations of most of the exploratory trenches at GETR, review of the many papers and reports dealing with the seismic, geophysical, tectonic and geologic setting for the GETR site.
I have also provided reviews and my personal evaluation of the origin of the shears at GETR, and assisted the Staff in evaluating responses to questions, preparing answers to interrogatories, and correlating with the faults at GETR with other regions that have historic surface rupturing from earthquakes.
Q.4.
Summarize the results of your review.
A.4.
My personal conclusions regarding the faults at GETR, and the potential maximum earthquakes for this site are summarized in Appendix E of the Staff's Safety Evaluation Report of May 23, 1980. My main conclusions
i
, i are that the shears are pcrt of the complex Verona fault zone, that future surface faulting has high probability for.rerupturing the older shears and loa likelihood of forming new breaks, that the most recent surface offset is of late Holocene age, and that the most probable surface offset will be about 2 to 3 feet on a reverse-slip or left-oblique-reverse-slip fault.
The worldwide data and the San Fernando earthquake data suggest that the offsets could be as nuch as 2 to 2.5 meters. The associated earthquake would be about 6 to 6.5 magnitude.
Tne Staff use of 1 neter of offset beneath the GETR is conservative in
[
several respects:
the likelihood of a new rupture through the foundation during the next faulting' surface event is very low; the evidence for the three' faults that were trenched near the site all have evidence for offset of froiii obout 2 to 3 feet for the most recent faulting event, or series of events; and the offset could have exaggerated net-slip displacement from surficial gravity effects.
