1.0 INTRODUCTION

Following the accident at the Fukushima Daiichi Nuclear Power Plant (NPP) resulting from theMarch 11,201 l, Great Tohoku Earthquake and subsequent tsunami, the United States Nuclear Regulatory Commission (NRC) established a Near-Term Task Force (I.{TTF) to conduct a systematic review of NRC processes and regulations and to determine if the agency should make additional improvements to its regulatory system. The NTTF developed a set of recommendations intended to clarify and strengthen the regulatory framework for protectionagainst natural phenomena. Subsequently, the NRC issued a 50.54(f) letter (NRC, 2012a) that requests information to assure that these recommendations are addressed by all United StatesNPPs. The 50.54(f) letter requests that licensees and holders of construction permits under 10CFR Part 50 reevaluate the seismic hazards at their sites against present-day NRC requirements. Depending on the comparison between the reevaluated seismic hazard and the current design basis, the result is either no further risk evaluation or the performance of a seismic risk assessment. Risk assessment approaches acceptable to the NRC staff include a seismic probabilistic risk assessment (SPRA), or a seismic margin assessment (SMA). Based upon the risk assessment results, the NRC staff will determine whether additional regulatory actions are necessary.This Report provides the information requested in Items I throughT of the "Requested Information" section and Attachment I of the 50.54(0 letter (NRC, 2012a) pertaining to NTTF Recommendation 2.1 for the Beaver Valley Power Station Unit 2 (BVPS-2). The BVPS-2 is located in Shippingport Borough on the south bank of the Ohio River in Beaver County. The Site is approximately one mile from Midland, Pennsylvania, five miles from East Liverpool,Ohio, and approximately 25 miles from Pittsburgh, Pennsylvania. BVPS-2 includes a pressurized water reactor Nuclear Steam Supply System (NSSS) and turbine generator furnishedby Westinghouse Electric Corporation. The balance of the unit was designed and constructed bythe Licensee, with the assistance of their agent, Stone & Webster Engineering Corporation S:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R418\R1\2734294-R418, Rev. 1.docx fESConsultlng 2734294-R-018Reaision 7 March 20, 20L4 Page 1.3 of 55 (S&W). The nominal NSSS power level for BVPS-2 is set at 2,910 Mega Watts Thermal (MWl. The operating license was issued in August of 1987. In providing the information contained here, FirstEnergy Nuclear Operating Company (FENOC)has followed the guidance provided in the Seismic Evaluation Guidance: Screening, Prioritization, and Implementation Details (SPID) for the Resolution of Fukushima Near-Term Task Force Recommendation 2.I : Seismic (Electric Power Research Institute [EPRI], 2013a).The Augmented Approach, Seismic Evaluation Guidance: Augmented Approach for the Resolution of Fulrushima NTTF Recommendation 2.1 : Seismic (EPRI, 2013b), has been developed as the process, if required, for evaluating critical plant equipment as an interim action to demonstrate additional plant safety margin prior to performing the complete plant seismic risk evaluations.Reference is made to FENOC's Partial Submittal (FENOC,20l3a) summarizingthe Site geologic and geotechnical information. The "Description of Subsurface Materials and Properties," and the "Development of Base-Case Profiles and Nonlinear Material Properties" presented in FENOC, (2013a), are repeated here for completeness. l.L SunnuanY oF LrcnnsrNc BASrs The original geologic and seismic siting investigations for BVPS-2 were performed in accordance with Appendix A to 10 CFR Part 100 and meet General Design Criterion 2 inAppendix A to l0 CFR Part

50. The Safe Shutdown Earthquake ground motion (SSE) was developed in accordance with Appendix A to l0 CFR Part 100 and used for the design of seismic Category I systems, structures, and components. The Category I SSCs are identified in Table 3-l of the Updated Safety Analysis Report (UFSAR) (FENOC,20I2).

1.2 Sunnu,lnv oF GRoUND MortoN Rnspoxsn SpECTRUM AND ScRTnNING RESULTS In response to the 50.54(f) letter and following the guidance provided in the SPID (EPRI 1025287 , 2012), a seismi c hazard reevaluation was performed. For screening pu{poses, a horizontal Ground Motion Response Spectrum (GMRS) was developed. Based on the results of the screening evaluation, BVPS-2 screens in for risk evaluation, a Spent Fuel Pool evaluation,S:\Local\Pubs\27il294 FENOC BeaverValley\3.1Q Report File\R418\R1\2734294-R41e, Rev. 1.docx AESGoneultlng 1.3 2734294-R-018Reuision 1, March 20, 2014 Page L4 of 55and a High Frequency Confirmation. In the I to I 0 Hertz (Hz) part of the response spectrum, the GMRS exceeds the SSE and above 10 Hzthe GMRS also exceeds the SSE.Onc,q,NIZATIoN oF THIS RnponrThe remainder of this Report is organized as follows: Section 2.0 provides the Seismic Hazard Reevaluation that was performed for the BVPS Site, including the probabilistic seismic hazard analysis (PSHA) for hard rock site conditions, the site response evaluation, seismichazard at theSSE control point, and the derivation of the horizontal GMRS. The discussion in Section

2.0 applies

to both Units 1 and 2 ofthe BVPS. Section 3.0 provides a summary of the BVPS-2 SSE ground motion. Section 4.0 provides the screening evaluation, including a comparison between the GMRS and SSE, and the screening evaluation outcome. Section 5.0 describes interim actions completed for BVPS-2, and Section 6.0 provides conclusions.

The Ohio River Valley is an erosional, flat-bottomed, and steep-walled valley. The bedrock of Pennsylvanian age is a sequence of flat-lying shale and sandstone strata occasionally inter-bedded with coal seams. It is overlain by about 100 feet (ft) thick alluvial granular terraces that formed during the Pleistocene. Plant grade is elevation (EL) 735 ft and the top of bedrock is at approximate EL 625 ft.The Site area is located in a region with a low rate of seismicity. Historically, no earthquake ofepicentral Modified Mercalli Intensity (MMI) V, or greater, has occurred within 80 miles of the Site. The Site has experienced vibratory ground motion as a result of regional and distant earthquakes, most notably the 181 l - 12 earthquake sequence at New Madrid, Missouri, and the1886 earthquake at Charleston, South Carolina.Category I SSCs are designed for a safe shutdown following SSE ground motions associated with horizontal peak ground acceleration of 12.5 percent of gravity (0.125g) at the rock surfaceat the base of the foundation level.2.1 RnctotrlAt, AND Locnl cEoLocYThe Beaver Valley Power Station (BVPS) is located in an unglaciated area on sand and graveldeposits along the Ohio River, west of Pittsburgh and a few miles east of the Pennsylvania -Ohio border. Physiographically, the Site is located in the Appalachian Plateau Province. The bedrock in the areais the Allegheny Formation of Pennsylvanian Age. It consists of approximately two-thirdsshale and one-third sandstone with several interbedded coal seams and a thin bed of fossiliferous Vanport limestone.The stratigraphic materials underlying the bedrock are characteized by various sedimentarysequences of Mississippian, Devonian, Silurian, Ordovician, and Precambrian age, consisting of S:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R-018\R1\2734294-R418, Rev. 1.docx AESGonsulting 2734294-R-0L8 Reaision 1.March 20, 2014Page L6 of 55 shales, interbedded sandstones, siltstones and dolomites, and limestone. These rocks overlie the Precambrian basement at a depth of approximately I 1,000 ft.Structurally, the bedrock is generally flat lying. It has a regional dip of approximately 15 to 20 feet per mile to the south and southeast with low amplitude anticlines and synclines. Theregional dip and structure were imposed by orogenic movements that formed the Appalachian Mountains, about 100 miles southeast of the Site, at the close of the Paleozoic Era.2.2 Pnon,q.g[ISTIC Sntsu tc H,qz,tnu Ax,q,lysIs2.2.1 Probabilistic Seismic Hazard Analvsis Results JIn accordance with the 50.54(f) letter (NRC, 2012a) and following the guidance in the SPID (EPRI, 2013a), a PSHA was completed using the recently developed Central and Eastern United States Seismic Source Characterization (CEUS-SSC) for Nuclear Facilities (EPRI/DOEAtrRC,2012). The PSHA uses a minimum moment magnitude cutoff of

5.0 forhazard

integration, asspecified in the 50.54(f) letter (NRC, 2012a).The CEUS-SSC model consists of distributed seismicity sources and repeated earthquake (RLME) sources. Distributed seismicity sources are characterized approaches: the M,nu* approach and the seismotectonic approach.large magnitudefollowing twoThe BVPS-2 PSHA accounts for the CEUS-SSC distributed seismicity source zones out to atleast a distance of 400 miles (640 kilometers [km]) around the BVPS-2. This distance exceeds the 200 mile (320 km) recommendation contained in NRC (2007) and was chosen for completeness. Distributed seismicity source zones included in this Site PSHA are the following: o Mesozoic and younger extended crust - naffow and wide (MESE-N and MESE-W). Non-Mesozoic and younger extended crust - narrow and wide (I'{MESE-Nand NMESE-W) Study Region (STUDY_R)Atlantic Highly Extended Crust (AHEX)Northern Appalachians (NAP)S:\Local\Pubs\279294 FENOC BeaverValley\3.1Q Report File\R-O18\R1\2734294-R{18, Rev. 1.docx AB$Consulting 2734294-R-018Reoision LMarch 20, 20L4 Page 1,7 of 55 o St. Lawrence Rift Zone, including the Ottawa and Saguenay grabens Zone (sLR)Extended Continental Crust - Atlantic Margin (ECC_AM)Illinois Basin Extended Basement (IBEB).

These were developed by FENOC as part of an on-going SPRA effon. Figure 2-I and Table 2-1 present the mean hard-rock hazard curves at the BVPS-2 Site resulting from the PSHA. Thehazard curves showthe mean annual frequency of exceedance (MAFE) for spectral acceleration at the seven response spectralfrequencies (100 Hz, 25 Hz, l0 Hz, 5 H2,2.5 H4 l Hz, and 0.5 Hz), for which the updated EPRI GMM (2013c) is defined.a a a a ASSGonsulting rC?S:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R-O18\R1\2734294-R{18, Rev. 1.docx 2734294-R-018 Reaision 1, March 20, 2014 Page 18 of 551.

The following sections describe the various inputs to the siteresponse analysis. These inputs are summarized in Appendbc A.2.3.1 Description of Subsurface Materials and Properties The site stratigraphy presented here is based in part on site-specific geotechnical investigationsreported in the UFSAR (FENOC,2012, Section2.5.4). Thirty-five dry sample borings at the Shippingport Power Station were supplemented by 30 additional borings at the BVPS. Theseincluded 10 dry sample borings on the high terrace, and the remaining borings located in the intermediate and low terrace materials. All borings penetrated approximately 20 ft into bedrock.The geologic profile below the reported subsurface investigation depth is based on the analysisof formation tops and bottoms from available deep well logs in the vicinity of the Site (within about 7 miles), obtained from the Pennsylvania Geological Survey. This is supplemented by information from West Virginia and Ohio Geological Surveys, as well as the UFSAR.The terrace deposits in the Site area are characterized by three levels: high, intermediate, andlow. The low tenace is the most recent, where the upper alluvial deposit is composed of brownsilty clay approximately 20to 30 ft thick. The intermediate terrace consists of medium clays extending to about EL 660 ft. The oldest, high terrace is the most abundant deposit atthe plant location. The terrace materials in the plant area(high terrace deposits) consist of unconsolidated and stratified sand and gravel outwash derived from the melting of glacial ice at the end of Pleistocene time. The surface sand and gravel layer is underlain by relatively dense and incompressible sand and gravel extending down to bedrock at approximately EL 625 ft. Major structures of the plant are founded in the high terrace sands and gravel either directly or on compacted backfill. Thin deposits of mud, silt, and sand deposited by flood water on the Ohio River and tributary streams overlay the terrace sands and gravel.The subsurface materials properties summarized here are based on the geotechnical investigations described in the UFSAR. The borings in the intermediate and low terrace materials retrieved undisturbed samples of surface clays and silts for physical testing. However,no samples were obtained in the high terrace materials. The properties for these materials are based on Standard Penetration Test (SPT) blow counts and in-situ geophysical measurements.

Appendix2G summarizes the geophysical investigations consisting of cross-hole, up-hole, and down-hole measurements in five drill holes located in the reactor area. Compression-and shear-wave velocities were measured from direct arrival times. A limited amount of seismic refraction survey investigation was also performed to verify the elevation of bedrock, and to determine velocity layering.Variabilities in the V, of the bedrock material and the overburden soil are estimated respectively, from velocity measurements and lab tests. and the SPT data. The deep rock stratigraphy, as well as the seismic velocities of these strata relies on sonic logs recorded in wells in the site vicinity (within 7 miles). The sonic data were converted to compression-wave velocities (Vo) and shear-wave velocities (Vr) based on published literature (Pickett, 1963; Rafavich, 1984; Miller, 1990; and Castagna, 1993) reflecting the material type (limestone and dolomite, anhydrites and salts), porosity and density, and to a lesser extent, the lithology. Additionally, based on published literature, VpAy', ratios for these types of geologic units were used to define the epistemic uncertainty for Vr.Varying unit thicknesses, incomplete well logs, and non-standard lithologic descriptions present some challenges to reliably estimating contact locations. However, the lithologic units in the region are generally flat lying and for the most pafi,laterally consistent. Consequently, the velocity structure in the wells examined is similar and consistent from well to well for similar depths. Due to the proximity of these deep wells to the Site and the general flat lying (low dip)nature of the geologic units, the unit lithologies and thicknesses can be reliably assumed to be similar to those below the Site Table 2-3 presents the summary geotechnical profile identifying the layer thicknesses, Vr, and uncertainties in these parameters.

The scale factor of 1 . 15 reflects a realistic range in Poisson's ratio for the type of geologic unitsfound in the Paleozoic rocks underlying the site. The V, profiles determined using the scalefactor represent the epistemic uncertainty in the soil and rock column from the Tully Limestone formation at EL -3,700 ft to the top of the Pleistocene Upper and Lower Terrace unit underlyingthe base of the RB foundation mat.Using the best-estimate Vs specified in Table 2-3,t\vee base-case profiles were developed usingthe scale factor of 1.15.

Strain-dependent dynamic parameters for the overburden soils are reported in Appendix2D, Figure 2D-3 of Beaver Valley Power Station Unit I [BVPS-I] UFSAR (FENOC,20I1), and Figure 2.5.4-71 of the BVPS-2 UFSAR (FENOC,20L2). The material damping ratio is limited to a maximum of 15 percent in the calculations following guidance in NRC (2007) (RG 1.208).Consistent with the SPID (EPRI 2013a), uncertainty and variability in material dynamic properties are included in the site response analysis. For the rock material over the upper 500 ft, uncertainty is represented by modeling the material as either linear or non-linear in its dynamicbehavior. To represent the epistemic uncertainty in shear modulus and damping, two sets ofshear modulus reduction, and hysteretic damping curves were used.

For the linearanalyses, the low strain damping from the EPRI rock curves was used as the constant damping values in the upper 500 ft. Below a depth of 500 ft, linear material behavior is assumed for bothmodels, with the damping value specified consistent with the kappa estimates for the Site (values discussed in Section 2.3.2.3 and shown in Table 2-5).2.3.2.3 KappaNear-surface site damping is often described in terms of the parameter kappa (EPRI, 2013a).Section B-5.1.3.1 of the SPID (EPRI, 2013a) recommends the following procedure forevaluating kappa: Kappa for a firm rock site with at least 3,000 ft (1 km) of sedimentary rock may be estimated from the average Vs over the upper 100 ft (Vrroo) of the subsurface profile.Kappa for a site with less than 3,000 ft (l km) of firm rock may be estimated with Q' of40 below 500 ft combined with the low strain damping from the EPRI rock curves and an additional kappa of 0.006s for the underlying hard rock. For the BVPS-2 Site, kappa was estimated using the first of the above approaches because thethickness of the sedimentary rock overlying hard rock is 4,380.9 ft. There is sufficientconfidence, based on deep well data,that the hard-rock horizon is more than 3,000 ft below theelevation of the RB foundation. Including a kappa of 0.006s for the underlying hard rock, thetotal site kappa is estimated to be 0.0213s for profile Pl, 0.0237s for profile P2, and 0.0193s forProfile P3.To complete the representation of uncertainty in kappa and, at the same time, reduce computational demands, a 50 percent variation to the base-case kappa estimates was added for profiles P2 and P3. For profilePZ, the softest profile, the base-case kappa estimate of 0.0237swas augmented with a 50 percent increase in kappa to a value of 0.032s, resulting in two sets ofanalyses for profileP2. Similarly, uncertainty in kappa for profile P3, the stiffest profile, wasaugmented with a 50 percent reduction in kappa, resulting in analyses with low strain kappavalues of 0.0193s and 0.0152s. The suite of kappa estimates and associated weights is listed in AFSGonsultlng rceS:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R418\R1\2734294-R418, Rev. 1.docx 2734294-R-01.8 Reaision LMarch 20, 2014 Page 31. of 55 Table 2-5. The base-case kappa estimates were judged to be the more likely (by 50 percent) withweights of

to the augmented values with weights of 0.4.To maintain consistency in the site response analyses, the low-strain damping values are adjusted consistent with the kappa value associated with each profile.TABLE 2.5 KAPPA VALUBS AND WEIGHTS USED IN SITB RESPONSE ANALYSIS Vnl.,ocrry PRorrr,nPRorrln Wnrcnr KappA, lsl K.Lpp.l, WnrcHr PI Base-Case 0.4 0.0213 (Kappa I )1.0 P2Lower Range 0.3 0.0237 (Kappa l)0.6 0.0320 (Kappa 2)0.4 P3Upper Range 0.3 0.0193 (Kappa 1)0.6 0.0152 (Kappa 2)0.4 This unsymmetric approach results in an appropriate representation of the epistemic uncertainty in site response. It also significantly reduces computational demands relative to specifying threealternative kappa values for each velocity profile. When uncertainty and variability in other inputs are also considered, it results in 6,600 site response analyses (5 combinations of profiles and kappa values ,2 material behavior models flinear and nonlinear for the upper 500 ft], 2 source models (single and double corner inputs), 1 I loading levels, and 30 soil profile realizations). The range of kappa values presente d in Tuhle 2-5 is utilized in the site response analysis that is combined with the hard-rock seismic hazard to obtain the control point seismic hazard and the GMRS.2.3.3 Randomization of Base Case ProfilesTo account for the aleatory variability in dynamic material properties that is expected to occuracross a site at the scale of a typical nuclear facility, variability in the V5 profiles and shear-strain-degradation shear modulus reduction, and damping curves are incorporated in the site response calculations.

As specified in the SPID (EPRI, 2013a), correlation of Vs between layers was modeled using the footprint correlation model. In the correlation model, a limit of +/- 2 standard deviations, and a factor of I .3 about the medianvalue in each layer was assumed for the limits on random velocity fluctuations. Additionally, profiles were constrained to not exceed a Vs of 9,200 ftls.2.3.3.2 Randomization of Modulus Reduction and Hysteretic Damping Curves For the BVPS-2 Site, aleatory variability in dynamic material property curves is represented using 30 randomizations derived from the base-case for each alternative model. The random generation of G/cn,u* and damping ratio values are limited to upper and lower bounds of the BE +two standard deviations, consistent with the SPID (EPRI, 2013a). The damping ratio values are limited to l5 percent. Also consistent with the SPID (EPRI, 2013a), a log normal distribution isused with a natural log standard deviation of 0.15 and 0.30 for modulus reduction and hystereticdamping, respectively.2.3.4 Input Fourier Amplitude Spectra Consistent with the guidance in Appendix B of the SPID (EPRI, 2013a), input Fourier amplitude spectra were defined for a single representative earthquake magnitude (M 6.5) using twodifferent models for the shape of the seismic source spectrum (single-corner and double-corner). By selecting appropriate distances and depths, a suite of I I different input amplitudes (median peak ground acceleration [PGA] ranging from 0.01 to 1.5g) were modeled foruse in the site response analyses. The characteristics of the seismic source and upper crustal attenuation properties used forthe analysis of the BVPS-2 Site were the same as those identified in Tables B-4, B-5, 8-6, and B-7 of the SPID (EPRI, 2013a) as appropriate fortypical Central and Eastern United States (CEUS) Sites.ABSGonsultlng rctS:\Local\Pubs\27il294 FENOC Beaver Valley\3. 1 Q Report File\R41 8\R19734294-R41 I, Rev. 1 .docx 2734294-R-0L8 Reaision 1March 20,2014Page 33 of 552.3.5 Site Response MethodologyThe site response analysis reported here implements an equivalent-linear method using the random vibration theory (RVT) approach. This process utilizes a simple, efficient method forcomputing site-specific amplification functions and is consistent with existing NRC guidance and the SPID (EPRI, 2013a). The guidance contained in Appendix B of the SPID (EPRI, 2013a)on incorporating epistemic uncertainty in Vs, kappa, dynamic material properties, and source spectra was followed for the BVPS-2 Site.2.3.6 Amplification FactorsThe results of the site response analysis consist of factors (5 percent damped pseudo absolute acceleration response spectra), that describe the amplification (or de-amplification) of referencehard-rock response spectra as a function of frequency and input reference hard-rock PGS amplitude. Amplification is determined for the SSE control point elevation at the base of the RBfoundation level. Because of the uncertainty and variability incorporated in the site responseanalysis, a distribution of AFs is produced. The AFs are represented by a median (i.e., log-mean) amplification value and an associated log standard deviation (sigma-ln) for each oscillator frequency and input rock amplitude. Consistent with the SPID (EPRI, 2013a), median amplification was constrained to not fall below 0.5 to avoid extreme de-amplification that mayreflect limitations of the methodology.Figure 2-4 presents the median and +l- I standard deviation in the predicted AFs developed forthe I 1 loading levels parameterized by the reference (hard rock) PGA (0.01 to 1.50g) for profilePl and EPRI rock G/G.*, and hysteretic damping curves (EPRI, 2013a). Further, the AFsshown on Figure 2-4 are developed for the hard-rock input motion based on the single-corner frequency source model. The variability in the AFs results from variability in Vs and modulus reduction and hysteretic damping curves. Figure 2-5 presents similar information for profile Plusing the linear dynamic material property representation. Comparison of AFs, including the effects of material nonlinearity in the BVPS-2 Site firm rock layers (model Ml),with the coffesponding AFs developed with linear site response analyses (model M2) shows only minor effects of non-linearity for frequencies below about 20Hz and a S:\Local\Pubs\27%294 FENOC Beaver Valley\3.1Q Report File\R418\R1\2734294-R{18, Rev. 1.docx AEtConsulting 2734294-R-018 Reaision L March 20, 2014Page 34 of 55 loading level less than about 0.5g.

PorNr Snrsvrrc HnzARD CunvBs As presented"in Section 3.2below, the control point elevation is taken to be the base of the RB foundation level (EL 680.9 ft). The procedure to develop probabilistic site-specific control point hazardcurves follows the methodology described in Section 8-6.0 of the SPID (EPRI,20I3a). This procedure (referred to as Approach 3) computes a site-specific control point hazard curvefor a broad range ofspectral accelerations given the site-specific bedrock hazard curve and site-specific estimates of soil or soft-rock response and associated uncertainties. This process is repeated for each of the seven specified spectral frequencies, for which the EPRI (2013c) GMM is defined.The dynamic response of the rock column below the control point elevation is represented by the frequency and amplitude-dependent amplification function (median values and ln-standard deviations) developed and described in the previous section. The resulting control point mean hazafi curves for the BVPS-2 Site are shown on Figure 2-6 and in Table 2-6 for the sevenspectral frequencies, for which the EPRI (2013c) GMM is defined.

Based ondeterministic hazard analysis, the UFSAR (FENOC,2012, Sections 2.5 and 3.7) reports twodesign basis earthquakes, the SSE and the Operating Basis Earthquake (OBE). The purpose ofthe seismicity analysis is to evaluate earthquakes that have been recorded historically andinstrumentally in order to determine the OBE and the SSE. The SSE ground motion accounts forthe soil conditions at the Site.The SSE response spectra for the BVPS-2 Site are anchored atzero period accelerations of O.l2lghorizontal and 0.0839 vertical (Section 2.5.4.9 of UFSAR [FENOC,2012]). Dynamic AFs used for these spectra give a maximum spectral acceleration of 0.449 for two percentdamping, with appropriate relative values for other amounts of damping. The spectra arc flatfrom 2to 6Hzandreduce to an amplification ratio of unity for frequency exceeding20Hz. The So/o-damped horizontal SSE spectral accelerations are presented in Table 3-1.

4.0 SCREENING

EVALUATIONIn accordance with the SPID, (EPRI, 2013a, Section 3), a screening evaluation was performed as described below.The screening process determines if a seismic risk evaluation is needed. The horizontal GMRSdetermined from thehazard reevaluation is used to characterize the amplitude of the updated evaluation of seismic hazard at the BVPS-2 Site. The screening evaluation is based upon a comparison of the GMRS with the horizontal SSE ground motion spectrum.4.1 Rtsr Ev,q.r-u.q.TroN ScnnBNrNG (1 To 10 IJz)Inthe I to l0Hzpart of the response spectrum, the GMRS exceeds the horizontal SSE (at frequencies above about 6Hz). Therefore, the plant screens in for a risk evaluation.The GMRS exceedance relative to the SSE spectrum above about 3-4 Hz is characterized asbroad banded with spectral accelerations exceedin10.4g at some frequencies in the 1.0 to l0Hz frequency range. However, the SSE spectrum envelops the GMRS below 3-4 Hz. Therefore,SSCs and failure modes associated with low frequency are not affected by the GMRS. Asdiscussed in the SPID (EPRI, 2013a), these SSCs and failure modes include flexible distribution systems, sliding and rocking of unanchored components, fuel assemblies inside the reactorvessel, soil liquefaction, and liquid sloshing in atmospheric pressure storage tanks. Accordingly,no new high confidence of low probability of failure (HCLPF) analysis of low frequency SSCs and failure modes is planned.4.2 Hrcu FnneunNcy ScnnnNrNG (> 10 Hz)In the range of frequencies above l0 Hz, the GMRS exceeds the horizontal SSE. The high frequency exceedances will be addressed in the risk evaluation discussed in,Section 4.1above.The BVPS-2 SSE ground motions do nothave significant frequency content above l0 Hz.Moreover, the consideration of high-frequency vulnerability of components in the IPEEE was focused on "bad actor" relays mutually agreed to by the industry and the NRC, with known S:\Local\Pubs\2734294 FENOC Beaver Valley\3.1Q Report File\R-O18\R19734294-R418, Rev. 1 .docx ABSGonsultlng 2734294-R-018 Reaision L March 20, 201.4Page 47 of 55 earthquake or shock sensitivity. These specific model relays, designated as low ruggedness relays, were identified in EPRI Report 7148 (EPRI, 1990). Rather than considering high frequency capacity versus demand screening, "bad actor" relays were considered programoutliers and were evaluated using circuit analysis, operator actions, or component replacement.The response of components to the high frequency ground motion associated with the GMRS will be addressed as part of the on-going SPRA. EPRI ReportNP-7498 (EPRI, l99l), as well asmore recent studies related to licensing activities for new plants (EPRI, 2007aand2007b), summarize the basis and conclude that "...high-frequency vibratory motions above about 10 Hzare not damaging to the large majority of NPP structures, components, and equipment. An exception to this is the functional performance of vibration sensitive components, such as relaysand other electrical and instrumentation devices whose output signals could be affected by high-frequenc y excitation. " The SPRA will utilizethe information from EPRI's on-going test program to develop estimates of fragility for potential high-frequency sensitive components. The test program is expected to"... use accelerations or spectral levels that are sufficiently high to address the anticipated high-frequency in-structure and in-cabinet responses of various plants." 4.3 Spnxr Funl Pool Ev,Ll,u.q,TloN ScnnnxING (1 ro 10 IJ.z) In the I to I 0 Hz part of the response spectrum, the GMRS exceeds the horizontal SSE. Therefore, a spent fuel pool evaluation will be performed following the guidance in SectionT of the SPID (EPRI, 2013a).S:\Local\Pubs\27%294 FENOC Beaver Valley\3.1Q Report File\R-018\R1\2734294-R418, Rev. 1.docx AESGonsultlng 2734294-R-018 Reaision L March 20, 2014 Page 48 of 555.0 INTERIM ACTIONS Based onthe screening evaluation, the expedited seismic evaluation described in EPRI (2013b)is being performed as proposed in a letter to NRC dated April 9,2013, (l{EI,2013), and agreedto by NRC in a letter dated May 7,2013, (ML131064331).Consistent with NRC letter dated February 20,2014, [ML14030A046]the seismic hazard reevaluations presented herein are distinct from the current design and licensing bases of theBVPS-2. Therefore, the results do not call into question the operability or functionality of SSCsand are not reportable pursuant to10 CFR 50.72, "Immediate notification requirements for operating nuclear power reactors," andlO CFR 50.73, "Licensee event report system."The NRC letter also requests that licensees provide an interim evaluation or actions todemonstrate that the plant can cope with the reevaluated hazard while the expedited approach and risk evaluations are conducted. In response to that request, NEI letter dated March 12,2014 (NEI, 2014), provides seismic core damage risk estimates using the updated seismic hazards forthe operating nuclear plants in the CEUS. These risk estimates continue to support the followingconclusions of the NRC GI- 1 99 Safety/Risk Assessment (NRC , 2010a):Overall seismic core damage risk estimates are consistent with the Commission's Safety Goal Policy Statement because they are within the subsidiary objective of 104/year forcore damage frequency. The GI-199 Safety/Risk Assessment, based in part on information from the NRC's IPEEE program, indicates that no concern exists regarding adequate protection and that the current seismic design of operating reactors provides asafety margin to withstand potential earthquakes exceeding the original design basis.BVPS-2 is included in the Marchl2,20l4, risk estimates. Using the methodology described inthe NEI letter, all plants were shown to be below 70'a lyeau thus, the above conclusions apply.Additionally, as requested in Enclosure 1 of the 50.54(f) letter (Item 5) the followingparagraphs provide insights from the NTTF Recommendati on 2.3 walkdowns, and the IPEEE program accomplished for BVPS-2. These programs further illustrate the plant seismic capacity.

This walkdown identified no major anomalies. However, some potentially adverse seismic conditions were identified during the SeismicWalkdown. The walkdown report summarizes these conditions. Condition reports were inititiated as appropriate. Justifications for findings, for which a Licensing Evaluation is not required, are provided in the Component's respective SWCs.The 2.3 walkdown for the Beaver Valley Power Station was subsequently audited by NRC staff.The staff concurred with the process, as well as the findings and conclusions. IPEEE DESCRIPTION AND CAPACITY RESPONSE SPECTRUMThe IPEEE for BVPS-2 accomplished a SPRA for selected plant SSCs (Duquesne Light Co,1995) in accordance with Nuclear Regulatory Commission Technical Report (NUREG)-1407 (NRC, 1991). The seismic fragilities, developed in support of the SPRA,are based onthe lE-4 return period UHRS developed in the EPRI SOG program (EPRI, 1989a, 1989b).The IPEEE HCLPF spectrum (IHS) is not used for screening. However, it is provided here for reference and to document the level of the BDB seismic ground motion, for which the plant SSCs have been evaluated. Appendix,B summarizes the elements of the IPEEE, following theIPEEE adequacy requirements in SPID Section 3.3.1 (EPRI, 2013a).The IPEEE reports aminimum HCLPF value of about 0.1259, associated with failure of the unrestrained station batteries. However, the supporting SPRA estimates a mean seismic-initiatedCDF of 5.338-6, andthe plant level HCLPF of 0.259 PGA (NRC, 2010b). Accordingly, the 5-percent damped horizontal IHS spectral accelerations provided in Table 5-1 corcespond to the 0.259 PGA UHRS. The SSE spectrum and the IHS in the horizontal direction are shown on Figure 5-1.ABSGonsulting rceS:\Local\Pubs\27%294 FENOC BeaverValley\3.1Q Report File\R-O18\R1\2734294-R-018, Rev. 1.docx 2734294-R-018 Reuision L March 20, 201,4 Page 50 of 55 0.8 TABLE 5-1 HORIZONTAL IHS FOR BVPS-2 Frequency (Hzl-BV2 IHS 0.259 -BV2 H-SSE, 0.L25g PGA FIGURE 5-1BVPS-2 SSE AND IPEEE HCLPF SPECTRA ,A a0 V s 0.6 o'tr (u L g ot ^A E L P (, o t o.z AESGonsultlng rce FnneuENCY lHzl SpncrRAL AccnLERATIoN tgl 1.0 0.019 2.5 0.125 5.0 0.292 10.0 0.369 25.0 0.369 100.0 0.250 S:\Local\PubsV734294 FENOC Beaver Valley\3 1Q Report File\R{18\R1U734294-R418, Rev 1 docx 273429+R-018 Reaision 1March 20, 2014 Page 51, of 55

6.0 CONCLUSION

S In accordance withthe 50.54(f) request for information letter (NRC, 2012a) a seismichazardand screening evaluation was performed for BVPS-2. This reevaluation followed the guidance provided in the SPID (EPRI, 2013a) and developed the control point GMRS for the Site. The screening evaluation compares the horizontal SSE spectrum to the control point GMRS.Based on the results of the screening evaluation, the plant screens in for risk evaluation, a SpentFuel Pool evaluation, and a High Frequency Confirmation. The GMRS exceeds the horizontal SSE both in the I to 1 0 Hzpart of the response spectrum and above l0 Hz.Although the BVPS-2 IPEEE is a focused scope SPRA and is not used for screening, this Report Q4ppendix B) performs the evaluation of the completed IPEEE. It concludes thatthe IPEEE is of good quality and meets all other prerequisites and the adequacy requirements in accordance with the SPID (EPRI, 2013a). The Report compares the GMRS to the IPEEE spectrum for reference and to illustrate the robustness in the plant design relative to the design basis for new plants.The SPRA for BVPS-2 is currently on-going and is expected to be completed consistent with the schedule proposed in the industry letter to NRC dated April 9,2013, (f{EI, 2013), and agreed toby NRC in a letter dated May 7, 2013, (MLl3106A33l).

Basedon the review of sonic log data from the three FirstEnergy Nuclear Operating Company (FENOC) Sites, an upper and lower V, limit is defined by a factor of

1.3 relative

to the base case V, for each of the three V, profiles.The SPID (EPRI,20l3a) specifies the use of the Electric Power Research Institute (EPRI) rock degradation curves for rock units such as found at the FENOC Sites. These curves were used forthe top 500 feet (ft) of rock. Below 500 ft, damping forthe bedrock is derived consistent with kappa estimates. At the BVPS-2 Site strain-dependent properties for the soil overburden are based on FSAR data for the Pleistocene Upper and Lower Terrace Units (1E).Consistent with the SPID (EPRI, 2013a), kappa is estimated for each site profile. Forboth the lower and upper range V, profiles, uncertainty is represented using a secondary kappa value by applying a factor of 1.5 (multiplied by 1.5 for LR profile and divided by1.5 for UR profile). For profiles greater than 3,000 ft the SPID (EPRI, 2013a) specifiesuse of an equation between V, (30m) and kappa; allthree profiles at BVPS-Z arc greaterthan 3,000 ft thickness. The total kappa is based on adding the soil kappa, the rock kappa, and the hard rock kappa.For the secondary kappa profiles the rock damping in the top 500 ft is modified by thesame factor of 1.5 used to characterize uncertainty in kappa. Below 500 ft rock damping was adjusted to preserve the total kappa for the profile.Table A-1 provided below specifies the site response inputs consistent with these assessment of uncertainty and variability. Table,4-8 lists the resulting median AFs and the related ln-sigma for seven selected frequencies and 1 I values of input hard rock peak ground acceleration (PGA).Tables A-9 to A-11 list the resulting median AFs and the related ln-sigma for three loading levels associated with Figures 2-6 and 2-7.S:\Local\Pubs\27%294 FENOC BeaverValley\3.1Q Report Fib\R-018\R1\2734294-R418, Rev. 1.docx AEgGonsulting 2734294-R-0L8 Reaision'LMarch 20, 2014 Page A3 of A1.0 O+)a (D (t)0.)t<c)u)(.)l.r rt)(l)li (D q tr g (B l.{c)GI tr (J F E a (.)F.\1 (J t<(D a (+r q ral lr)(l)*()U)(l)o g c)a-v ()I.r (rr'H lr)q o P t<.9 (l)Cg ,;vu)!2 >'aa aF.9 c.r!ia (l)=yu)A' 9)t!f J (u E tn o-c.P P (o qo 4 rl o bo rl q o E o L r*1r, (u f (o c.9 (o L (u o{J u (o-o c f o L bo-Y (o o o-rl F{(o.=brO c=.tl (u L.a-c o-(u E-o c (o ra (u L)c (o P.2 E-c v-3 tn d ll bo co_e$0Jco=<u EE st I co (u-o (o F 3 o (u-o E g:t o (F T E o E c, c, f o ttl P c'o o_o-c P.g T'(u at f v, (u+r (u E (I, L (o o-E c.9.=E E (n g (U o0 c (o&.o o-o-l?o'/) 'F F(E^.j .!rn:: E g d.e?E*s"i E.(E)o r-r p HE o tY)*r9:<-io Fi slr-o ttOl6t I3c;9;rl En=i- Fi-o E'i o^F!3E'-i o.e\OC l^*(Y')3E'-j o.\OC Q*o o 4 o ll=ET;-o m.ro str-o vt(Il+E 8o c-rr En=i- rl l-o E,i o^*g Ps'-'i cL\Otr E*rl (U obI cc='d>RE ur)(o qE o o rn d tl=sa osf?6 tg" *i;fl-v, (J o&E o-IJ.J Cs'-'i o.:OE Q*o o ul o tl 3 t; $i s Hu Yo=-t F 3E uru.(o (uq!gc='d}RE rn(o.?E o o 4 o ll=bo co-eq 0Jco=c, EF N g L (u uo c (E t L (u 3 o J.ll c o.F rn(E FIN!.1 F{ E= >o (u ,\.actlE I.EOE<.(u,,(U*E; E.(oEt O Fur P 008 t o (i)Eg gF sfr-o t/r(u(O 3 9c;97" Eh=tr3 Er F!3E'-i o.\otr l^*(n SE'-'i o\OC Q*o o 4 o tl=-q':<ai+SF slr-o vrosl 39c;5;rl Ea=icn r-o E'i o^F!bP.= 'a\OL Q3 sf L (o (Uht cc='d bRE rn(o c!E rl o rn ci tl 3 Lo 9d t(, 8*dro Eoo c_o i; ,(1J J (J o E E o-UJ Pe'-'i o.:OE Q*o o 4 o il 3 s-OO tE s i e Hu; oE$F 3E uJ -^(o (ua!cc='d;RE rn(o r! .tJ Fl o rn c;tl 3 bo go-eq olO=<u EE rl o-(u P (o E'F vl IJ.J tt1 a)m vlc o F (o.!NG-40(u- $E d ?E ,,N; 3E (oO FE c (o t o (n-o:<d9 s5 lIe t'a(uF{ge,, t,fr='= Fl-c\l-o E,i o^F!3E'-1 0.\OC il*(n L 3E'-1 0.-\OC Q*o o a o tl=o-o (o.9 E-o-P o z o-o (E.9 E-o-o z (u-o (It.9 E.o.o z o, lt (o.9 E-o o z gO 9a= (/)8T drd Toa, c-cl i;g.Y tJ o E a o-ul gg'-1 o'\OC Q*o o rn c;ll=c, trl F trJ oc 4 F l o z:t o-c (u (J f o.J).9 E.9 c),Jl o E o (u (J 5 o.'1 o o L o-(!o-a^iEF{Y. -}/.o.t -.e u)fi o o t.r')o o F (u o o- q1 iJg Fl o rn P-c.go (u 3 (o o-o^g!o-v-tn o o In o-o F (u o L o 6.1 ER F{o lrl+,-c.9p a)3 9e (o=ttt E fP E=sry!a_3E-c(o (,O E g (o (/)d* Ps 5'aY* Ets i83 (U (u-c rll F-A--z H ti Ltd<i crl QZ'iA tiv EF{444 dkl E- lV--Fl t-0 fBSConsulting rctS:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R-018\R1\2734294-R418, Rev. 1.docx 2734294-R-018 Reaision 1 March 20, 20L4Page Aa of A10 L,rynn ElnvlrloN tftl Pnoprln P1 DnprH lftl PRonLn P2 Dnprn lftl PnoprlB P3 Dnprn lftl 680.9I 100 0 9s7 0 1265 0 66s l 100 r5.9 957 t5.9 1265 ts.9 665 1200 15.9 1043 1s.9138015.9 625 1200 55.9 r043 55.9 1380 55.9 625 s000 55.9 4348 55.9 5750 55.9 550 5000 130.9 4348 r30.9 5750 130.9 550 6026 130.9 5240 130.9 6%A 130.9 3s0 6026 330.9 5240 330.9 6930 330.9 350 6744 330.9 5864 330.9 7756 330.9 300 6744 380.9 5864 380.9 7756 380.9 300 6744 380.9 5864380.97756380.9-r20 6744 800.9 5864 800.9 7756 800.9-t20 7tt2 800.96l 84 800.9 8t79 800.9-2994 1ttz 3674.9 6t84 3674.9 8179 3674.9-2994 6416 3674.9 5579 3674.9 7378 3614.9-3700 6416 4380.9 5579 4380.973784380.9 -3700 9200 4380.9 9200 4380.9 9200 4380.9TABLE A.2 SHBAR WAVE VELOCITY [ftls] PROFILESTABLE A-3 KAPPA (K1) USBD WITH BEST ESTIMATE PROFILE Pl Klppn (nocx) Bnsno oN: LoG (k) : 2.2189 - 1.093

Nevertheless, it is summarized here for information, and because the IPEEE findings indicate that the plant design is seismically robust and exhibits significantmargins in excess of the designbasis. The IPEEE, was performed in accordance with the guidelines in Nuclear Regulatory Commission (NRC) Technical Report (NUREG)-I4I7 (NRC, 1991). The plant high confidences of low probability of failure (HCLPF) value estimatedfrom the Core Damage Frequency (CDF) is reported to be 0.259 peak ground acceleration (PGA). It is largely controlled by failure scenarios involving the station batteries. B.L IPEEE PrerequisitesThe SPID (EPRI 2013a) guidelines require that the following prerequisites be documented priorto the possible use of the IPEEE, for screening.Confirm that commitments made under the IPEEE have been met. If not. address and close those commitments.Confirm whether all of the modifications and other changes credited in the IPEEEanalysis are in place.Confirm that any identified deficiencies or weaknesses to NUREG-1407 (NRC, 1991) in the plant specific NRC Safety Evaluation Report (SER) are properly justified to ensure that the IPEEE conclusions remain valid.Confirm that major plant modifications since the completion of the IPEEE have notdegraded limpacted the conclusions reached in the IPEEE. As part of the NTTF 2.3 Seismic walkdown effort for BVPS-2, the IPEEE was examined to verify that the corrective actions were implemented and documents closed.

The NTTF 2.3 walkdowns identified no potential adverse seismic conditions. The BVPS-2 IPEEE identified no seismic vulnerabilities for the Plant. This was recognized bythe NRC in NUREG-1437 Supplement 36 "Generic Environmental Impact Statement for License Renewal of Nuclear Plants, Supplement 36, Regarding Beaver Valley Power Station Units 1 and 2" (NRC , 20A9) Page G20 and 21 states "The NRC staff also notes that the use of the integrated PSA to facilitate identification of SAMAs for external events, the prior implementation of plantmodifications for seismic and fire events, and the absence of external event vulnerabilities ensure that the search for external event SAMAs was reasonably comprehensive."8.2 IPEEE Adequacy DemonstrationConsistent with the guidelines in NUREG -1407 (NRC, l99l), the BVPS-2 IPEEE is based on aseismic PRA (SPRA), which extends the internal events PRA (IEPRA). The SPRA evaluates the risk contribution and significance of seismic initiated events to the total plant risk. The SPRAwas selected to accomplish the IPEEE over the seismic margins assessment based on the following considerations

The SPRA would be integrated with the IEPRA. The integrated PRA would consistently treat all internal and external initiating events. This model rigorously accounts for all accident sequences resulting from any combinationof internal and external events. The resulting risk information provided fromthis integrated approach was viewed as more useful to management to make decisions about allocating resources to manage the risks of severe accidents.With the ability to link the Level 1 and Level 2 event trees as demonstrated inthe IPE submittal, the selected PRA approach was found to provide a more rigorous examination of potential containment vulnerabilities andseismic/systems interactions impacting containment effectiveness than was possible using the seismic margins approach.With the previous decision to perform an internal events PRA for the IPE, theability to utilize insights from the completed internal events PRA, and the external events capabilities of the software that was used, there was a higher confidence that the seismic PRA would be completed within the resourcesS:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R418\R1\2734294-R-018, Rev.

Seismic events below about 0.1g were found to have an insignificant chance of failing any equipment. Seismic events above 1.33g were of low enough hazard and were ignored. The seismic PRA results showed that95 percent of the seismic CDFcomes from earthquakes that arc at least twice as severe as the peak ground acceleration of the SSE (0.125g). Core damage sequences resulting from earthquakes between roughly one and twotimes the SSE, mainly involved seismic failure of either emergency DC power or emergency AC power.The following paragraphs briefly summarize the IPEEE in accordance with the guidelines of the SPID (EPRI 20r3a).8.2.1 Building Seismic AnalysisThe design seismic analysis of Category I structures of BVPS-2 is based onthe time history modal supe{position method using simulated time histories representing the SSE spectra.Lumped mass models of the buildings were utilized in the seismic analysis. These models represent the building mass at floor elevations and include the floor system, a portion of thewalls above, and the walls below the floor system, and major component and equipment loads.S:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R-O18\R1\2734294-R-018, Rev. 1.docx AESGonsutrlng 2734294-R-01.8Reaision 1March 20, 20L4Page 85 of 87In addition, masses are located at elevations where any other response values are required. The lumped masses are connected by story stiffnesses.Most major structures of the BVPS-2 are founded on the dense gravel layer underlying the upperterrace deposits. The soil structure interaction (SSD effects on the seismic response are represented by soil springs representing the stiffness and damping characteristics of the supporting soil medium. The soil springs represent a range of shear moduli values to envelopethe variation of peak floor response periods. Additionally, the Containment Building seismicmodel considers uncracked and partially cracked reinforced concrete sections to account for normal and pressurized conditions.Modal responses from the dynamic model are combined using the square root of the sum of the squares (SRSS) method to establish Seismic Category I structure seismic loads. This is usedeven when modes have closely spaced frequencies, since no well-established criterion tocombine modes under this condition was available. In-structure response spectra used as seismic inputs to Category I structural systems, components, and equipment are derived from the lumped mass dynamic models. The dynamicmodel is also used to determine forces and overturning moments on the building structure, Overturning moments are combined with vertical acceleration forces in order to check structure overturning stability and subgrade reactions.Seismic response forces and stresses are determined for simultaneous application of horizontaland vertical earthquake ground motions using the response spectrum technique. It is assumedthat the response in the vertical direction is uncoupled from the lateral motion. Accordingly, two dynamic models, one for horizontal and one for the vertical, are used to obtain the respective response. The responses obtained from the two-dimensional planar models are combined usingthe SRSS method.8.2.2 IPEEE Seismic Response In-structure response spectra (ISRS) for use in the seismic IPEEE were developed using medianbased soil properties, structural properties, and the median 1x10-4 uniformhazard spectrum.S:\Local\PubsV7U294 FENOC BeaverValley\3.1Q Report File\R-o18\R1\2734294-R418, Rev. 1.docx fFGonculting 2734294-R-01.8 Reaision 1 March 2A, 201.4Page 86 of 87 The best estimate (BE) structural models used for this analysis were based on the mathem aticalmodels used in the design seismic analysis.The design basis SSE floor response spectra for one percent damping are scaled by use of S&A in-house computer program PSD 107 .1. Scaling of the spectra incorporated the following:. Change PGA from 0.l25gto 0.1519. Change Equipment Damping Ratio from I percent to 5 percent. Change SSE response spectrum shape to the IPEEE Uniform Hazard Spectrum Shape The scaling assumes that the IPEEE analysis is based on the composite modal dampingdeveloped from the soil-structure interaction (SSf analysis performed in 1979,limited to 7 percent.The seismic floor response spectra developed as described above and used for the fragility evaluations are provided in the IPEEE Report (Duquesne Light Co, 1995).8.2.3 Screening of ComponentsThe development of the Safe Shutdown Equipment List (SSEL) and the screening evaluations were performed following the SPRA guidelines and based on the plant systems models. Initial screening prior to the walkdowns was based on HCLPF levels estimated relative to the median spectral shape of NUREG/CR-0098 (Newmark and Hall,1978) anchored to 0.3g. Thesubsequent fragility analysis used floor response spectra associated with the Review Level Earthquake (RLE) spectrum. This screening utilized the guidelines in EPRI NP-6041 (EPRI, Ieel).8.2.4 Seismic Capability WalkdownsThe IPEEE walkdowns were performed to support the subsequent fragility analysis, and toscreen out components that have a high enough HCLPF value and the site hazard curves.

The walkdowns assessed potential seismic vulnerabilities, assigned preliminary HCLPF values, and identified potentially seismic-vulnerable component(s) in each group of similar type components based on the preliminary HCLPF values andthe importance of the component as determined inthe IPE. PreliminaryHCLPF values were assigned based on judgment and experience of the seismic reviewteam, andreferences from both the Seismic Qualification Utility Group (SQUG) and EPRI NP-6041 (EPRI leer).The seismic capacities for other components were conservatively assigned based on the morevulnerable components in each group. Upon completion of the initial sequence quantifications the fragilities of significant contributors were improved using component-specific analysis. Aconfirmatory walkdown of components verified that representative fragilities of each group arestill applicable after detailed study. B.3GMRS and IHS ComparisonThe IPEEE for BVPS-2 is not used for the plant screening evaluation. However, comparison of the IPEEE HCLPF spectrum (IHS) and the horizontal ground motion response spectra (GMRS)at the base of the Reactor Building (RB) foundation level shows that the GMRS exceeds the IHSin the range of frequencies of interest.S:\Local\Pubs\2734294 FENOC BeaverValley\3.1Q Report File\R418\R1V734294-R{18, Rev. 1.docx AEgCortsultlng APPENDIX C REACTOR BUILDING MEAN AND FRACTILESEISMIC HAZARD CURVES BVPS-2 SITE fE$Gonsultlng ]-Ct S:\Local\Pubs\27%294 FENOC Beaver Valley\3. 1 Q Report File\R4l8\R1\2734294-R41 8, Rev. 1 .docx 2734294-R-41.8 Reaision 1 March 20, 201.4 Page C2 of C1-2 APPENDIX C .
