ftRC STAFF TESTItt0ilY OF WILLIAM J. HALL Q.1.
Please state your name and present occupation.
A.1.
lty name is *.filliam J. Hall. My position is that of Professor of Civil Engineering at the University of Illinois at Urbana-Champaign, and I l
an alsa an independent consulting engineer.
I Q.2.
Please suonarize your educational background and relevant work experience.
A.2.
B.S. in Civil Engineering, University of Kansas, Lawrence 1943 M.S. and Ph.D. in Civil Engineering, University of Illinois at Urbana-Chanpaign, 1951 and 1954, respectively.
As the University of Illinois I have been involved in teaching and research in structural engineering and structural dynamics for over 30 years.
In recent years I have been principal investigator on several large research programs concerning earthquake enginearing sponsored by the flational Science Foundation.
In addition, ny consulting activities in structural and seismic engineering have included, among many assignments, the following:
(a) nuclear 8165050694
. power plants since 1964, (c) trans-Alaska Pipeline since 1970, (c) Canadian sector of the Aloska-Canada gas line since 1980, and (d) the uranium hexa-fluoride gas centrifuge enrichment plant since 1973.
I was a nenber of the Applied Technology Council projects ATC-3 and ATC-6 dealing with the develop-nent of seismic design criteria for buildings (1974-1977) and bridges (1973-1931), and have consulted on military system design in the area of structural dynanics since 1953. A sunmary of my educational and professional background is attached and is nade a part of this testimony.
Q.3.
Please describe the scope of your participation in the review of the General Electric Test Reactor for this proceeding.
A.3.
At the time of the initial Show Cause revica, the Staff contracted with II. ft. flewaark Consulting Engineering Services to recommend the proper seismic design criteria to be used for the GETR and to provide a reconmen-dation, based on a review and evaluation of analyses submitted by General Electric, as to the seismic adequacy of the GETR facility to meet the appro-priate criteria.
During this review period, I carried uajor responsibility for reviewing the GETR seismic issues, fly recommendations and evaluations have provided the basis for certain portions of the Staff's SFRs.
Q.4.
Please summarize the results of your review.
A.4.
After discussion with a number of persons and a review of reports, documents, and letters from flRC, the U.S. 'ieological Survey, and the TERA Corporation, studies for Diablo Canyon, and recognizing the lack of corre-lation of damage to structures and equipment in relation to peak acceleration, in the light of our judgment and experience Dr. flewmark and I recommended the
0
. use of the criteria described below for the seismic evaluation of the GETR site and participated in the review of safety-related structures and equip-nent at the site.
On the basis of considerations of the type noted, we reconnended that the nost reasonable value of acceleration to use for anchoring the spectra for effects arising fra, the Calaveras fault would correspond to 0.6 g (consistent with a nagnitude in the range of 7.0 to 7.5), but for design or review conservatism we suggested a value of 0.75 g.
This value reflects the fact that there is sone degree of uncertainty in estimating such motions 4
and that the hazard specified by the USGS corresponded to a magnitude 7.5 earthquake.
We noted that we did not expect fault notion of significance to be transferred to the site from activity on the Calaveras fault.
In a similar manner, in the case of the Verona Fault, we stated that, from the information available, an acceleration value of about 0.40 g (consistent with a magnitude in the range of 5.0 to 6.0) was the most reasonable value for anchoring the response spectra, but for conservatism we reconaended use of a value of 0.6 9 The margin between the most likely value and the recommended value here is larger to account for a greater degree of uncertainty as to the nature of the seismic motion and for the fact that the USGS specified the hazard to be that associated t:ith a magnitude 6.5 earthquake.
Also we noted that the motion was to be taken as acting simultaneously with a fault motion of not more than 1 meter, interpreted to be the resultant (net) motion in any arbitrary direction.
With regard to effective acceleration, the instruments that are used for free-field ground motion measurements are strong motion accelerographs for
. the most part.
Acceleration, as a measure of ground motion, can be inter-preted as an item of engineering interest in the sense of force, through Newton's second law, namely that pertaining to nass and acceleration.
Of equal interest to the earthquake engineer are the velocities and displacenents arising from the excitation which can be obtained on a time basis through integration of the acceleration record.
Reliable instruments do not exist at present for recording velocity and displacement as a function of time in the frequency ranges that are associated with earthquake excitation.
Actually, extremely high accelerations can occur on a localized basis with no damage to structures or equipment.
Many types of structures as well as equipment are designed to resist very high frequency accelerations in the range of hundreds to thousands of gravities, as for exanple in the case of military structures and equipment (submarines, missiles, ground vehicles and underground structures).
If one strikes a building with a structural wrecking ball, localized damage and high accelerations occur in the region where the ball strikes the building; generally, such localized loading for a well engineered structure does not lead to building collapse or even any type of gross damage. Accordingly, earthquake excitation with a few high frequency acceleration peaks, characterized for design and analysis purposes by Reg.
Guide 1.60 spectra, would not be expected to produce significant damage.
The concept of effective acceleration has been defined by Dr. Newmark in the following manner:
It is that acceleration which is most closely related to structural response and to damage potential of an earthquake.
It differs fron and is less than the peak free-field accel-I I
eration.
It is a function of the size of the loaded area, the frequency content of the excitation, which in turn depends on the closeness to the source of the earthquake, and to the weight, embedcent, and stiffness of the structure and its foundation.
. This definition of effective acceleration describes the tern as used by Dr.
Newmark and myself during our review of the GETR.
As enployed herein for nuclear plant design and review analysis, the tena effective acceleration is associated with the significant part of the ground notion as cnaracterized by the repetitive motion portions which possess strong energy content.
This portion of the ground notion obviously is of prinary importance in evaluating the response and behavior of the structure or equipment elements, and thereby of importance in design and in assessing damage potential.
In this sense, thei, in accordance with the definition given by Dr. Newmark, the effective ;cceleration normally is r.ot that value connected with the high spikes of instrumentally recorded high frequency accelerations commonly found to occur close to the source of seisnic energy release, such as in the case with GETR with respect to the Verona and Calaveras faults.
On the other hand, the effective acceleration would be expected to be very close to the peak instrumental acceleration for loca-tions at significant distances from the source, zones where such high frequency acceleration peaks normally are not encountered.
Accordingly, for design purposes, the effective acceleration value is used to anchor the design response spectrum.
As indicated, for GETR we would expect an effective design acceleration value of 0.75 g, consistent with the NRC Staff j
position for peak vibratory ground motion of slightly in excess of 1.0 g.
The results of our review, as well as our conclusions regarding the earthquake ground motion design critiera are contained in Section C and Appendix A of the Staff's May 23, 1980 SER and Appendix A of Je October 27, 1980 SER.
