ABSTRACT The draf t version of this report presented updated Lawrence Livermore National Laboratory (LLNL) probabilistic seismic hazard analysis estimates l
for 69 nuclear power plant sites in the region of the United States east of l
the Rocky Mountains.
LLNL performed a re-elicitation of seismicity and j
l ground motion experts to improve their estimates of uncertainty in l
l seismicity parameters and ground motion models.
Using these revised inputs, i
LLNL updated the seismic. hazard estimates documented in NUREG/CR-5250 (1989).
These updated hazard estimates will be used in future NRC actions.
The draf t was issued for public comment in October 1993.
By the end of the public comment period, February 28, 1994, comments had.been received from l
two nuclear industry companies.
T1.e comments.from these companies neither i
contested nor suggested amendments to the technical data conveyed in the report.
Rather, they both suggest changes in the Individual Plar.t External Event Examination (IPEEE) program scope.
This report is not the forum for discussion of the IPEEE program.
Possible modification of the scope of'the IPEEE will be examined in its own setting.
Therefore, there are no technical differences between the draft report and.this final report.
Any l
information as to modifications to the IPEEE program will be provided to l
the public via an NRC general communication.

1 INTRODUCTION The study described in this report is an update of a probabilistic-seismic.
hazard analysis (PSHA) study presented in NUREG/CR-5250.
Probabilistic evaluations are intended to capture the uncertainties in estimating seismic hazard in the Eastern United States (EUS), the region east of the Rocky:
Mountains.
These uncertainties include those encountered in.the selection.of seismic source zones, rates of seismicity, upper magnitudes,-ground motion models, and site correction models.
The U.S. Nuclear Regulatory Commission (NRC) has been sponsoring the development of PSHA methodology by-Lawrence Livermore National Laboratory (LLNL) since the 1970's (NUREG/CR-1582).
In the 1980's NRC sponsored an LLNL study to develop a seismic hazard methodology for all operating nuclear power plant sites in the EUS (NUREG/CR-3756, NUREG/CR-5250). These probabilistic estimates were conducted, in part, as a result of a 1982 letter from the U.S.
Geological Survey (USGS) to the NRC.
In that letter the USGS suggested that deterministic and probabilistic evaluations of seismic hazard should be made for sites in the EUS to assess the-likelihood of large earthquakes along the eastern seaboard.
The 1980's LLNL methodology included input data provided by 11 seismicity experts and 5 ground motion experts. The seismicity experts defined maps of source zones of uniform seismicity and then described the seismicity of each zone in terms'of the rate of earthquakes versus magnitude for each zone.
The ground motion experts each providad several attenuation models for predicting ground motion as a function of distance from the earthquake source.
LLNL developed a seismic hazard model that used the experts' input and a Monte Carlo simulation approach to provide an estimate of the probability of exceeding a level of ground motion (peak ground acceleration and spectral acceleration values) at a given site.
LLNL applied its methodology to develop probabilistic seismic hazard estimates at all 69 EUS operating plant sites (NUREG/CR-5250).
In conjunction with funding LLNL to perform a PSHA study, NRC recommended that 4
the nuclear power industry perform an independent study to provide a coordinated utility position on PSHA estimates and to provide NRC with comparative information. A consortium of nuclear power utilities (the Seismicity Owners Group) funded the Electric Power Research Institute (EPRI) to perform a seismic hazard study.
EPRI developed its own PSHA methodology and PSHA estimates at 56 of the EUS sites (EPRI NP-4726, EPRI-NP-6395-D).
The differences between the LLNL and EPRI seismic hazard estimates were addressed in NUREG/CR-4885.
For example, the EPRI seismicity information was provided by six teams of geoscience experts as opposed to the 11 individual seismicity experts used in the LLNL methodology. The LLNL study described in this report did not examine the differences between the LLNL and EPRI seismic hazard estimates.
Instead, this study concentrated on improving the elicitation of data and its associated uncertainty from the experts to better capture the true uncertainty in our state of knowledge.
In the past few years LLNL has applied its methodology to studies at Department of Energy (DOE) sites. During these recent applications, LLNL re-examined the expert opinion elicitation process used in the 1980's LLNL methodology to better characterize uncertainty. On the basis of insights gained from these applications, NRC sponsored a limited re-elicitation of the LLNL experts to refine the estimates of uncertainty in seismicity and ground motion estimates.
In 1992 and 1993 LLNL re-elicited input data from the seismicity and ground motion experts using a revised elicitation procedure.
Then LLNL revised the pSHA computer code and produced updated PSHA estimates at EUS sites. The results presented here are the improved and updated estimates. A detailed description of the updated methodology is contained in LLNL Report UCRL-ID-115111.
These updated hazard estimates will be considered by the NRC staff in future licensing actions such as safety evaluation reports, reviews of individual plant examination of external events (IPEEE) submittals (NUREG-1407), and early site reviews.
2 SEISMICITY INPUTS TO HAZARD ANALYSIS In probabilistic seismic hazard analyses, the experts define maps of source zor,es and then describe the seismicity of each zone in terms of the rate of earthquakes versus magnitude for each source zone. The Gutenberg-Richter relationship (Log N(m) - a - bm) describes the number of earthquake (N) expected as a function of magnitude (m) (Figure 1). As reported in NUREG/CR-5250, the seismicity experts were asked to provide a and b values (the intercept on the y-axis and the slope of the rate of earthquakes versus magnitude) for each source zone. The experts were asked to then estimate the uncertainties associated with these a and b values.
This procedure led to large uncertainties for the seismicity recurrence rates at the larger magnitudes.
The 1992 elicitation of seismicity experts improved the modeling of uncertainty in seismic recurrence rates, especially at the larger magnitudes.
In the current approach, experts were interviewed individually at interactive meetings, instead of filling in questionnaires as they did in the 1980's.
Before the interview, aach expert was provided with a package of materials that included recurrence curves based on observed seismicity and recurrence estimates based on the a and b values provided by the experts in the 1980's study. The recurrence curves based on the instrumental period (last 30 to 40 years of recorded seismicity) were more helpful because they provided information on the frequency of smaller magnitude earthquakes.
The curves for the entire historical period (last 300 years) were more helpful for the larger magnitude earthquakes.
At the interview, LLNL explained the problem with the earlier elicitation of a and b values and described the revised elicitation procedure.
The experts were then given the opportunity to revise the maximum magnitudes for each source zone on the basis of recent information.
Seismicity recurrence rates, including uncertainty, were elicited by asking the experts their median estimate and bounds ( 5th and 85th percentiles) for N(m) at two magnitude values - magnitudes 3.75 and a magnitude value 3/4 of the way between NUREG-1488 2

LLNL used data diagnostic tools to check the seismicity inputs for consistency with historical seismicity data. The 1992 elicitation was limited to the seismicity recurrence rates and upper magnitude values.
Zonation was not re-elicited.
All the seismicity experts were more comfortable with the revised approach.
The result of the elicitation was that the uncertainties associated with every
' expert's seismicity recurrence curves were reduced significantly at all magnitudes, although there was little change in the preferred values. The estimates of maximum magnitude were generally unchanged.
3 GROUND MOTION INPUTS TO HAZARD ANALYSIS For the 1980's LLNL study reported in NUREG/CR-5250, five ground motion experts provided models that estimated ground motion as a function of earthquake magnitude and distance from the site.
LtNL combined the inputs i
from all pairs of seismicity and ground motion experts individually to develop an uncertainty distribution estimate of hazard for each pair of experts.
In the recent elicitation of ground motion experts, emphasis was placed on i
uncertaiaty estimates and the state-of-the-art ground motion models.
To improve the elicitation of ground motion information, a workshop on elicitation was held in May 1992 on elicitation of expert opinion.
The workshop participants considered the type of information needed, the format of the elicitation (questionnaires or interviews) and the aggregation of expert opinion. The recent elicitation procedures used by LLNL followed the recommendations developed during this workshop.
The workshop participants suggested that the most appropriate form for eliciting ground motion variability is to elicit the probability distribution l
of ground motion, with uncertainty, for selected values of magnitude and i
distance from the site. The workshop participants recommended that the elicitation process involve a meeting to disseminate ground motion information, individual elicitation of the experts and a group feedback meeting. The workshop participants also recommended that the ground motion inputs be aggregated to derive an aggregated ground motion distribution.
A workshop was held in August 1992 to disseminate the most recent research results for ground motion in the EUS and elicit ground motion information.
Each expert was elicited individually in interactive meetings with LLNL, LLNL used data diagnostic tools to check the ground motion inputs for consistency.
The ground motion elicitation resulted in estimates of ground motinn (peak ground acceleration and spectral acceleration) at specific earthquake magnitudes and distances from a site (e.g., for magnitude 5.0 at a distance of 10 km). After the workshop there were additional discussions with the ground motion experts.
LLNL combined the individual ground motion estimates into a composite ground motion model to be used as input for the hazard calculations.
The ground motion ir.uts were combined to form an empirical uncertainty distribution for median e- 'n tes of ground motion.
Then an empirical conditional uncertainty NUREG-1488 4

4 HAZARD ESTIMATES AND COMPARIS0N TO PREVIOUS RESULTS j
j Using the updated inputs and following the Monte Carlo procedure, which was 1
used in their previous studies, LLNL calculated PSHA. estimates for all j
operating plant sites east of the Rocky Mountains.
A public meeting was held on March 9, 1993, to present the LLNL preliminary hazard results. The LLNL l
report describing the updated methodology (UCRL-ID-115111) is available in the NRC Public Document Room (memorandum from P. Sobel to G. Bagchi, dated-October 1
l 8, 1993).
The 1993 LLNL hazard results for the 69 sites are documented in i
l Appendix A (mean peak ground acceleration estimates) and Appendix B (uniform i
hazard response spectra).
For the purpose of comparing these estimates to the seismic design at nuclear power plant sites, a table of safe-shutdown earthquake spectral values is documented in Appendix C.
All the spectra in i
the appendices are at 5 percent of critical damping.
l l
Although the comparison of LLNL and EPRI hazard estimates was not an objective of this program, we find that the updated LLNL methodology reduced the LLNL f
l hazard estimates, thus reducing the differences between the LLNL and EPRI hazard estimates.
Figures 2 and 3 show a comparison of the 1989 LLNL, 1993 l
LLNL and EPRI peak ground acceleration hazard estimates at two plant sites.
l The largest differences between the 1993 LLNL and EPRI hazard estimates are at l
low seismicity sites and soil sites.
Figures 4 and 5 show a comparison of the 1989 and 1993 LLNL spectral velocity hazard estimates at two plant sites. The-15th, 50th, and 85th percentile and mean hazard estimates were all reduced. The updating reduced the mean hazard l
estimate by a factor of 5 to 30 at a peak ground acceleration of 0.2g.
The uncertainty in the hazard estimates (e.g., the difference between the 85th and i
50th percentiles) was lowered substantially (Figure 6, which is the same as i
Figure 5 except the y-axis is linear).
'1 Sensitivity studies were performed to determine the effects of using the updated seismicity and ground motion inputs. Updating the seismicity inputs j
reduced the mean hazard estimates substantially (by a factor of 5)~at a peak ground acceleration of 0.29 Updating the ground motion' inputs reduced the mean hazard estimates by a factor of 1 to 10 at a peak ground acceleration of l
0.29; this reduction appears to be site dependent.
Further sensitivity studies are planned for 1994 to allow us to better understand the effects of the updated seismicity and ground motion inputs.

10 SUPPLEME NTARY Noif S Update of NUREG/CR-5250 11 AB5T R ACT cae.vnem sw eis The draft version of this report presented updated Lawrence Livermore National Laboratory (LLNL) probabilistic seismic hazard analysis estimates for 69 nuclean power plant sites in the region of the United States east of the Rocky Mountains. LLNL performed a re-elicitation of seismicity and ground motion experts to improve their estimates of uncertainty in seismicity parameters and ground motion models. Using these revised inputs, LLNL updated the seismic hazard estimates documented in NUREG/CR-5250 (1989). These updated hazard estimates will be used in future NRC actions. The draft was issued for public comment in October 1993. By the end of the public comment period, February 28,1994, comments had been received from two nuclear industry companies. The comments from these companies neither contested nor suggested amendments to the technical de:a conveyed in the report. Rather, they both suggest changes in the Individual Plant External Event Examinaaon (IPEEE) program scope. This report is not the forum for discussion of the IPEEE program.
Possible modification to the scope of the JPEEE will be examined in its own setting. Therefore, there are no l
technical differences between the draft report and this final report. Any information as to modifications to the j
IPEEE program will be provided to the public via an NRC general communication.
