SUBJECT:
SEISMIC EVALUATION OF BUILDING 102 0F THE GENERAL ELECTRIC VALLECITOS NUCLEAR CENTER The purpose of this memorandum is to recomend endorsement of the attached review as a staff position and a basis for succeeding increments of the analysis of the effects of natural phenomena upon existing plutonium fabrication facilities. A draft of the Los Alamos Scientific Laboratory (LASL) report has been reviewed by Dr. C. K. Chou, Lawrence Livemere Laboratory; Dr. J. R. Mcdonald, Texas Tech University; Dr. W. J. Hall and Dr. Nathan H. Newmark, Nathan M. Newmakk Associates; J. Mishima, Battelle Northwest Laboratory; and J. E. %er, W. Burkhardt and Dr. W. E. Vesely, NRC. The final LASL report incorporates the results of that review.
Drs.. Hall and Newmark have documented their assessment in the attached report dated September 29, 1930.
We reconmend that this review including its sur. nary and conclusions be adopted as a staff position subject to your approval.
Subsequent to your approval, we will make copies available to the public and to the General Electric Company in accordance with review and doctnentation procedures agreed upon and described in our February 10, 1977 memorandum to R. M. Bernero.

Dear Mr. Burkhardt:
This report contains cur evaluation of the capability of Building 102 of the General Electric Vallecitos Nuclear Center to withstand seismic shaking and fault motion. Our report is based in part on material contained in Ref.1, as well as on the supporting Engineering Decision Analysis Company reports noted in Ref. 1.
One of the authors of this report, Dr. W. J. Hall, visited the site and inspected Building 102 in June 1977 and again briefly in April 1979; in the interim both of us have participated in numerous meetings and telephone conversations with personnel from the U.S. Nuclear Regulatory Commission, with EDAC during l
the early stages, and most recently with LASL concerning evaluation of l
the noted facility.
Description of Facility The General Electric Vallecitos Nuclear Center is located 5 miles SSE of Plea nton, California on the north side of the Vallecitos Valley.

C0:iDITIO:15 CC:1SIDERED At:0 SASIS OF EVALUATI0ti The purpcse of this report is to define a raticnal basis for seismic evaluatien of the General Electric test reactor and other facilities located near Vallecitos, California. The major facilities considered are within three miles of the Calaveras Fault and very close to, or possibly just over, a fault identified as the Verona Fault.
r After discussion with a number of persons and a review of reports, documents, and letters from fiRC, the U.S. Geological Survey, and the TERA Corporation, studies for Diablo Canyon', and recognizing the lack of correlation of damage to structures and equipment in relatica to peak accelera-tien (including the 6 August 1979 Coyote Lake earthquake and the 15 Octobcr 1979 Imperial Valley earthquake), in the light of our judgment and experience we recommend the use of the criteria described herein for the seismic evalua-tion of the site and for the review of structures and equipment in structures at the site.
It is noted that these recommendations are the writers' sole responsibility and do not represent the offici'ai views of f;RC or the USGS.
It is considered that an earth:;uake of magnitude 7 to 7.5 might e
occur on the Calaveras Fault and tha icenter mignt be located close to :he m aH

BASIS OF EARTHQUAKE GROUtiD MOTION DESIGil CRITERIA by W. J. Hall and fl. M. Newmark fiathan M. tiewmark Consulting Engineering Services 1211 Civil Engineering Building Urbana, Illinoit 61801 IrlTR000CTI0ft The purpose of this background memorandum is to describe in more detail the basis of our reasoning employed in arriving at the recommended seismic review criteria for the Vallecitos site as presented in our memorandum of 14 April 1980. Our reco=endations remain unchanged.
It is important to note that the earthquake ground motion design criteria constitute but one part of the design criteria employed in the design or review of a nuclear facility.
The most important seismic effects for a nuclear plant arising from l
earthquake-induced motions at the site normally would be expected to occur i
from earthquakes having a source close to the site rather than from more l
distant earthquakes on the various fault systems. This observation has been taken into account in arriving at the recommendations for the Vallecitos facility since the sources are considered to be possibly very close to, or under, the site.
Most of the information availfole about earthquake motions is l
probabilistic in nature but, in the absence of definite probabili. ic approaches and established criteria for estimating such effects, the dhl#Tgt 1 JXE
