AFFIDAVIT OF ROBERT F. JACKSON AND JAMES P. KNIGHT STATE OF MAP,YLAND

COUNTYOFMONTG0MERY)
I, Robert E. Jackson, being duly sworn, state as follows: I am Branch Chief, Geosciences Branch, employed by the Office of Nuclear Reactor Regulation, U. S. Nuclear Regulatory Commission. A copy of my professional qualifications is attached.
I, James P. Knight, being duly sworn, state as follows:
I am Assistant Director for Components and Structures Engineering employed by the Office of Nuclear Reactor Regulation, U. S. Nuclear Regulatory Commission. A copy of my professional qualifications was previously introduced into the record.
On October 15, 1981, the Atomic Safety and Licensing Board issued a
~
Memorandum and Order in which it ordered that the Staff file by October 26, 1981 further written testimony, to be presented at a
~~
further hearing, responding in full to recently distributed Board experts' reports (emphasis added).

At an October 9, 1981 meeting with the Applicant to discuss these reports, and in a related letter to Harold Denton of the same date, we were notified by the utility that an accelerogram from an earthquake which occurred on October 16, 1979 had been obtained. This uncorrected accelerogram contains a peak acceleration of approximately 0.35g for a magnitude = 2.6-2.7 earthquake ehent which is in excess of a prehious 0.259recordedehentneartheMonticelloreterhoironAugust 27, 1978 which has been the subject of considerable discussion during this proceeding. This information is the subject of a Staff " Board Notification",
dated October 20, 1981.
On October 13-15, 1981, we were further infonned that the Applicant will be conducting field tests during the week of October 19, 1981, in the form of blast testing, to further ehaluate the hypothesis that ground motion recorded at the U. S. Geological Surhey accelerometer on the dam itself may be amplified due to topographic effects. We were also informed that the U. S. Geological Surhey installed another accelerometer in the Monticello reserhoir area in 1980 which is not located on the dam. The significance of this instrument is that records obtained from it would not be influenced by topographic effects such as may be the case with the accelerograph located on the dam itself. If records from this instrument areahailablethentheymaybemoreapplicabletothesite. On October.J9, 1981 we receihed a copy of U. S. Geological Surhey Open-File Report 81-1214
" Processed Accelerogram fron Monticello Dam, Jenkinshille, ' South Carolina,
,16 October 1979, 0706 UTC."
l The Staff rehiew of the Board experts' reports is in progress. Nonetheless, it is our opinion that, in order for the Staff to be prepared to respond in full to the Board experts' reports, a complete ehaluation of the abohe described new information is needed. This is because:
1.
Thenewly-ahailableaccelerogramcouldbesignificanttothestaff's ehaluationofboththeApplicantandBoardexperts'stressdrop calculations and arguments. The October 16, 1979 earthquake has a lowermagnitudeandappearstohaheahypocentrallocationata greaterdistancefromtheaccelerographthantheprehiousehent, and,therefore,coulddirectlyaffecttheobserhedstressdropfor areserhoir-inducedehent.
2.
The accelerogram for the October 16, 1979 ehenthasseheral higher peak accelerations and, therefore, the ground motion response spectra developed from it could be more energetic than theprehiousehent. Analysis of this response spectrum could prohide a significant additional basis for ehaluation of the applicant's proposed ground motion model.
3.
Since the site conditions at the dam (topographic effects) may cause a site-dependent enhancement of ground motion as compared to the plant site, the results of this field experiment, which will not be ahailable until early Nohember, could prohide a directtestoftheYalidityofthispossibilitybyindicating whetherornottherecordsfromtheinstrumentareYalidfor comparison with'the site itself.

This information and the analysis of it could directly affect the substance of the Staff's response to the Board experts' reports.
1 The Staff sent a request for additional information on October 20, 1981 to the Applicant for analysis of this new information. We anticipate that the Applicant will be able to prohide this information inseYeralweeksandiftheinformationproYidedisfoundtobe adequate, the Staff will be able to respond in full to the Board experts' reports approximately four weeks following the receipt of this information and.a meeting with the Applicant.

ROBERT E. JACKSON, JR,, PH.D.
GEOSCIENCES BRANCH Division of Engin2erinq U. S. NUCLEAR REGULATORY COMMISSION My name is Robert E. Jackson.
I presently reside at 6609 Carleton Court Laurel, Maryland 20310 and am employed as Branch Chief, Geosciences Branch, Division of Engineering, Office of Nuclear Reactor Regulation, -
Washington, D. C. 20555.
PROFESSIONAL QUALIFICATIONS I. received a B. S. degree in Geology from the University.of Rhode Island, and a Ph.D. degree in Geology f rom the University of North Carolina with a specialty in structural geology - rock mechanics.
I have been employed by HRC since August 1974.in the areas of Structural Geology and Fault Geology as applied to the evaluation of the suitability of nuclear power plant sites. My area of expertise includes structural geology of igneous, metamorphic and sedimentary rocks, rock. mechanics, teconophysics, petrology, and fault identification and behavior.
I am experienced in field analysis.
From 1973 to 1974 I was employed by Martin Marietta Laboratories in Baltimore, Maryland as a research scientist. My work for this corporate research and development labor 6 tory consisted of a variety of problem-solving programs in rock mechanics relating to quarrying and blasting..
I also contributed to programs in r&pid tunneling and. excavation technology.
I also was involved in evaluating and developing new technologies for the crushed stone quarrying industry.
I directed a program of investigation of sliding f riction as it relates to earth-quake source mechanicsms and frictional behavior of fault. zones. While at Martin Marietta Laboratories, I was an author or co-author of 12 professional papers in these various fields.
From 1969 to 1973, I was a research assistant and teaching assistant at the University of North Carolina. My activity as a research assistant was in the development of a triaxial rock mechanics laboratory. One project I conducted in this lab was a study of experimental rock dilatancy as an earthquake mechanism. My dissertation was a study of sliding friction in foliated rocks and fault mylonites, including the behavior of fault gouge.
Teaching experience consisted of teaching undergraduate and advanced structural geology laboraqtries as well as teaching field mapping.
I have presented papers at national meetings of professional societies to which I belong, including the American Geophysical Union, Geological Societf of America, and the International Society for Rock Mechanics.
s
._,,m--
O From September A978 to May 1979, I served as Leader, Geology and Feismology Section, Geosciences Branch. Since May, 1979 I have been Chief, Geosciences Branch.
In this capacity I am responsible for rr.anaging staff review of the geological, seismologic, and geotechnical engineering. aspects of nuclear facilities for which applications for licenses have been made. Since joining the Nuclear Regulatory Commission staff, I have participated in the licensing activity for approximately thirty sites.
