SUBJECT: ENDORSEMENT OF ELECTRIC POWER RESEARCH INSTITUTE FINAL DRAFT
REPORT 1025287, "SEISMIC EVALUATION GUIDANCE"
Dear Mr. Pollock:
On behalf of the Nuclear Regulatory Commission (NRC), I am responding to the Nuclear Energy
1
Institute's (NEl's) letter of November 27,2012, with attached Electric Power Research Institute
(EPRI) final draft Report No. 1025287 entitled, "Seismic Evaluation Guidance: Screening,
Prioritization and Implementation Details (SPID) for the Resolution of Fukushima Near-Term
Task Force Recommendation 2.1: Seismic" (hereafter referred to as the SPID report). NEI's
letter was submitted to support licensee responses to Enclosure 1 of the March 12, 2012,
information requese that was issued pursuant to Title 10 of the Code of Federal Regulations
(10 CFR), Section 50.54(f) (hereafter referred to as the 50.54(f) letter). The 50.54(f) letter was
issued as part of the lessons learned from the accident at the Fukushima Dai-ichi nuclear
facility.
The NRC staff interacted with the stakeholders on the development of the SPID report with a
focus on screening, prioritization, and implementation details as they relate to performing a
seismic reevaluation. The SPID report is the product of significant interaction between the
NRC, NEI, EPRI, and other stakeholders, at over fifteen public meetings,3 over a 9-month
period. These interactions and the insights gained from the meetings allowed for the
development of this document in a very short time frame. The meetings helped develop the
expectations for how licensees would perform plant evaluations after updating their seismic
hazard information. At each meeting, the NRC staff provided its comments on the current
version of the SPID report and discussed with stakeholders proposed subsequent revisions to
the document. This iterative process, over a 9-month period, resulted in the final version of the

document. The NRC staff's endorsement of the SPID report, subject to the additional guidance
noted below, is based upon this cumulative development process resulting from the extensive
interactions between stakeholders and the NRC staff.
The NRC staff has reviewed the SPID report and confirmed that it would provide licensees with
the guidance necessary to perform seismic reevaluations. and r6port the results to the NRC in a
manner that will address the Requested Information items (1) through (9) in Enclosure 1 of the
50.54(f) letter. The SPID report is intended to provide sufficient guidance for all sites, however,
each site is unique and requirements for analYSIS can vary. lri cases where the SPID report

may not account for the unique characteristics of a site, prudent and sound engineering
judgment should be employed to assure all issues bearing on the hazard and risk evaluations
are adequately addressed. Instances when unique site characteristics require such engineering
judgment, or require analysis that is not included in the SPID report, should be clearly identified,
along with the measures taken to assure the unique site characteristics are appropriately
addressed.
Although the NRC staff finds that the performance and reporting of the seismic reevaluation in
accordance with the SPID report would be responsive to the 50. 54(f) letter, there are four further
issues described below for which the NRC staff provides additional guidance. These issues
are: (1) the use of the Individual Plant Examination of External Events (IPEEE) submittals for
screening purposes; (2) development of foundation input response spectra (FIRS) consistent
with the site response used in the development of the site-specific ground motion response
spectrum (GMRS); (3) updating the seismic source models; and (4) development of the site
response.
Use of IPEEE for Screening
Section 3.3 of the SPID report provides the criteria used to determine if the licensee's previous
IPEEE submittal is adequate to use for screening purposes. A seismic assessment performed
as part of the IPEEE program that demonstrates a plant capacity that is higher than the new
GMRS can be used to screen out plants, provided they meet certain adequacy criteria.
Each licensee has the option of demonstrating the adequacy of its previous IPEEE submittal for
screening purposes as part of its response to the 50.54(f) letter. The NRC staff will review each
submittal and determine whether the provided information demonstrates the adequacy of the
IPEEE analysis and risk insights. The licensee's description of each of the adequacy criteria,
described in Section 3.3 of the SPID report, will be reviewed by the NRC staff in its integrated
totality, rather than using a pass/fail approach. As such, even if one or more of the criteria are
not deemed to be adequate, the staff may still decide that the overalllPEEE analysis is
adequate to support its use for screening purposes. The NRC staff may conduct site visits to
view IPEEE documentation referenced in support of the IPEEE adequacy submittal.
Development of Foundation Input Response Spectra (FIRS)
The SPID report does not discuss the development of FIRS used for performing soil-structure
interaction analyses. Consistent with guidance described in DC/COL-ISG-017, "Ensuring
Hazard-Consistent Seismic Input for Site Response and Soil Structure Interaction Analyses,"
the FIRS should be derived in a manner consistent with the site response used in the
development of the site-specific GMRS. As such, the FIRS should be derived as
performance-based site-specific response spectra at the foundation level in the free field. The
starting point for development of the FIRS should be the same hard rock elevation used as the
starting point for developing the GMRS. As the engineering properties of soil are strain­
dependent and can be highly non-linear, the characterization of soil layers and their associated
properties used in the GMRS analysis should also be used for the derivation of the site-specific
FIRS at the foundation elevation. The performance-based FIRS can be developed using either
a full-column outcrop motion that includes the effect of the soil above, or as a geologic outcrop
motion for which the soil layers above the foundation elevation have been removed.

Updating the Central and Eastern United States (CEUS)-Seismic Source Characterization
(SSG) model
Section 2.2 of the SPID report provides an overview of the CEUS-SSC model and explains why
it is appropriate to use without update for the seismic reevaluations. Specifically, Section 2.2
states, "for site-specific licensing applications or site-specific safety decisions, these seismic
sources would be reviewed on a site-specific basis to determine if they need to be updated.
Such evaluations would be appropriate in a licensing application, where focus could be made on
site-specific applications. However, for a screening-level study of multiple plants for the
purpose of setting priorities, the use of these seismic sources as published is appropriate."
The NRC staff agrees that the CEUS-SSC model does not need to be updated for the seismic
reevaluations, but the staff's rationale is different than that presented in the SPID report.
Specifically, the staff has determined that the CEUS-SSC model does not need to be updated
because the model is up-to-date and is sufficiently refined to allow a site-specific source model
to be developed. To adequately respond to the 50.54(f) letter, a site-specific GMRS should be
calculated for each plant so that an informed decision can be made regarding which plants will
be required to complete a risk evaluation. Further, the site-specific GMRS will also be used in
the risk evaluations, if needed.
Prior to issuing the CEUS-SSC model, the Technical Integration Team considered potentially
significant events (such as the 2011 Mineral, VA earthquake) that had occurred after the model
was developed, and determined that those events did not change their interpretations of seismic
sources or earthquake recurrence rates. If a significant earthquake in the CEUS were to occur
or new information were to emerge during the reevaluation period that could require an update
of the CEUS-SSC model, the staff expects licensees to evaluate the significance of the new
information to determine if the CEUS-SSC model needs to be updated in order to appropriately
respond to the 50.54(f) request.
Site Response
Section 2.4.1 and Appendix 8 of the SPID report provides guidance on how to develop the site
response in cases where limited site response data exists. As stated in Appendix 8, the NRC
staff expects licensees to use available geologic, geotechnical, and geophysical data collected
during the initial licensing or subsequent activities at the site to the extent practicable. Where
limited site response data exists, information from core borings and data collected from site and
regional evaluations should be used to develop the site response amplification. Section 4 of the
SPID report states that licensees should provide the basis for the site responses used in the
reevaluations. The NRC staff expects site-specific geology, geotechnical, and geophysical
information to be a significant part of the basis.
In accordance with the 50.54(f) letter, each licensee is to submit to the NRC its intention to
follow the NRC-endorsed seismic reevaluation guidance, or an alternative approach, 60 days
after the issuance of the NRC-endorsed guidance. For the purpose of meeting this deadline,
the 60-day response period commences on the date this endorsement of the SPID report is
published in the Federal Register.

Licensees may use the SPID report as one acceptable method for responding to the information
requested in Enclosure 1 of the 50.54(f) letter. Accordingly, the NRC staff's issuance of this
letter endorsing the SPI D report is not considered backfitting, as defined in 10 CFR
50.1 09(a)(1).
The NRC requests that EPRI publish a final version of the SPID report within 1 month of receipt
of this letter. The final version of the SPID report should incorporate this letter between the title
page and the first section, and remove the draft markings from the document. If you or your
staff have additional questions, please contact my office or Mrs. Lisa Regner, of my staff at 301­
415-1906, or by email at [email protected].
