Enclosure Seismic Hazard Report by the Office of Nuclear Reactor Regulation Virgil C. Summer Nuclear Station, Unit 1 Docket No. 50-395 1.0 Overview This report 1 provides the U.S. Nuclear Regulatory Commission (NRC) staffs updated seismic hazard curves and response spectra for the Virgil C. Summer Nuclear Station, Unit 1 (VCSNS) site 2 that are based on the implementation of: (1) a new seismic ground motion model for the central and eastern United States (CEUS), and (2) recent advances in site response analysis.
The NRC staffs updated hazard curves (i.e., Tables A-1 through A-3) are included in Appendix A to this report.
2.0
Background
In response to the March 11, 2011, Great East Japan Earthquake and Tsunami, which triggered an accident at the Fukushima Dai-ichi nuclear power plant, the NRC established the Near-Term Task Force (NTTF) to conduct a systematic and methodical review of NRC processes and regulations in order to determine whether the agency should make additional improvements to its regulatory system. In SECY-11-0093, Near-Term Report and Recommendations for Agency Actions Following the Events in Japan, dated July 12, 2011 (NRC, 2011), the NRC staff recommended actions to clarify and strengthen the regulatory framework for protection against natural hazards. In particular, NTTF Recommendation 2.1 (NTTF R2.1) instructed the NRC staff to issue requests for information to all power reactor licensees pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Section 50.54(f) (10 CFR 50.54(f) letter (NRC, 2012)). to the 10 CFR 50.54(f) letter requested that licensees reevaluate the seismic hazards at their sites using present day NRC requirements and guidance to perform a probabilistic seismic hazard analysis (PSHA), and to develop a site-specific ground motion response spectrum (GMRS). To comply with the 10 CFR 50.54(f) request, the Nuclear Energy Institute submitted Electric Power Research Institute (EPRI) Report 1025287, Seismic Evaluation Guidance: Screening, Prioritization, and Implementation Details (SPID) for the Resolution of Fukushima NTTF Recommendation 2.1 Seismic, dated November 27, 2012 (EPRI, 2012). Recipients of the 10 CFR 50.54(f) letter committed to following the SPID to develop seismic hazard and screening reports (SHSRs). By December 2017, the NRC staff had finished assessing the SHSRs for all operating U.S. nuclear power plants.
Under the process for the ongoing assessment of natural hazards information (POANHI) described in SECY-16-0144, Proposed Resolution of Remaining Tier 2 and 3 Recommendations Resulting from the Fukushima Dai-ichi Accident, dated December 26, 2016 (NRC, 2016), the NRC staff continuously pursues and integrates new natural hazards information for operating plants in the United States. The Office of Nuclear Reactor Regulations Office Instruction LIC-208, Process for the Ongoing Assessment of Natural Hazards Information, issued November 2019 (NRC, 2019), provides guidance to the 1 Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML24221A060 (letter) and ML24221A061 (enclosure).

staff on how to collect, integrate, and evaluate new information for consideration in its regulatory decision-making. This report presents the NRC staffs latest understanding of seismic hazards at the VCSNS site following the POANHI framework.
The VCSNS site is located in Jenkinsville, SC, which is approximately 26 miles Northwest of Columbia, SC. It is adjacent to the Monticello Reservoir in the Piedmont physiographic province and is founded on early Paleozoic age metamorphic and igneous rock.
3.0 Motivation After evaluating the SHSR submittals that the NRC staff captured in NUREG/KM-0017, Seismic Hazards Evaluations for U.S. Nuclear Power Plants: Near-Term Task Force Recommendation 2.1 Results, issued December 2021 (Munson et al., 2021), the information was used to develop the GMRS at each of the U.S. nuclear power plants. This includes a compilation and synthesis of: (1) information provided by licensees in their SHSRs, (2) information collected by the NRC staff during its reviews of the SHSRs, and (3) information subsequently collected by the NRC staff from the scientific and engineering literature pertaining to several of the nuclear power plant sites. In addition, NUREG/KM-0017 includes updated approaches and relationships, relative to those recommended by the SPID, that the NRC staff used to perform its analyses.
After the development of NUREG/KM-0017, a new Senior Seismic Hazard Analysis Committee (SSHAC) Level 3 ground motion model (GMM) for Eastern North America (called NGA-East) was published by Goulet et al. (2018). In addition, the NRC staff also participated in a SSHAC Level 2 study, documented in Research Information Letter 2021-15, Documentation Report for SSHAC Level 2: Site Response, issued November 2021 (Rodriguez-Marek et al., 2021). This SSHAC Level 2 study implemented the SSHAC approach to performing site response analyses (SRAs). The SSHAC process, described most recently in NUREG-2213, Updated Implementation Guidelines for SSHAC Hazard Studies, issued October 2018 (Ake et al., 2018),
provides a structured and logical framework for the systematic evaluation of alternative data, models, and methods. This seismic hazard report for the VCSNS site incorporates the NGA-East GMM in place of the EPRI (2013) GMM; however, because the rock beneath the site is competent with high shear wave velocities (), the NRC staff did not perform an SRA.
4.0 Methods 4.1 Reference Rock Hazard For the reference rock PSHA, the NRC staff used the distributed seismicity zones (DSZs) from the SSHAC Level 3 Central and Eastern United States Seismic Source Characterization for Nuclear Facilities (CEUS-SSC) model in NUREG-2115, Central and Eastern United States Seismic Source Characterization for Nuclear Facilities, issued January 2012 (NRC, 2012).
Specifically, the NRC staff selected the DSZs that are located within 500 kilometers of the site.
For this reevaluation, the NRC staff used the SSHAC Level 2 update to the CEUS-SSC seismicity catalog and recurrence parameters (Gatlin, 2015), which primarily impacts sites close to the 1886 Charleston earthquake sequence. In addition to the nearby Charleston CEUS-SSC repeated large-magnitude earthquake (RLME) source, the NRC staff selected additional RLME sources that are within 1,000 kilometers of the site. To develop the reference rock seismic hazard curves for the site, the NRC staff used the NGA-East GMM (2018) to compute the median and logarithmic standard deviation of the spectral accelerations. Because the NGA-East GMM implements the rupture distance parameter, the NRC staff developed virtual rupture planes for each of the distributed source zones surrounding the site. For each virtual rupture, the NRC staff used the CEUS-SSC hazard input document (NRC, 2012) to specify the size of the rupture plane and the orientation of the rupture plane in terms of the strike and dip angles, dip direction, and rupture type (e.g., reverse and strike slip). In contrast, to develop the hazard curves for NUREG/KM-0017, the NRC staff used point source approximations for the CEUS-SSC and EPRI GMM (EPRI, 2013) combination.
Figure 1, located in Section 8 of this Seismic Hazard Report, shows the distribution of the virtual ruptures for one of the four alternative CEUS-SSC seismotectonic DSZ configurations, along with the resulting 10-Hertz (Hz) mean hazard curves that were developed using the NGA-East GMM. In particular, Figure 1 shows the distribution of the surface projection of the updip segments of the virtual rupture planes for each of the five seismotectonic DSZs within 500 kilometers of the site. As expected, the Extended Continental CrustAtlantic Margin (ECCAM) source zone, which surrounds the site, is the largest contributor to the 10 Hz reference rock mean hazard curves at the 10-4 annual frequency of exceedance (AFE) level.
Similarly, Figure 2 shows the distribution of the virtual ruptures for one of the three alternative CEUS-SSC maximum-magnitude DSZ configurations, along with the resulting 10 Hz mean hazard curves developed using the NGA-East GMM. The Mesozoic-and-Younger Extension Narrow Configuration (MESEN) source zone, which surrounds the site, is the largest contributor to the 10 Hz reference rock mean hazard curves at the 10-4 AFE level.
Figure 3 shows the RLME sources within 1,000 kilometers of the site, and their contribution to the 1 Hz reference rock mean hazard, from using the NGA-East GMM. The Charleston RLME source, which is the closest to the site, is the largest contributor to the 1 Hz reference rock mean hazard curves at the 10-4 AFE level.
Figure 4 shows the contribution from all the DSZs relative to the RLME sources, as well as the total mean hazard for the 1 and 10 Hz mean reference rock hazard curves, from using the NGA-East GMM. For both the 1 and 10 Hz mean reference rock hazard curves, the RLME sources provide the largest contribution at the 10-4 AFE level.
Finally, Figure 5 shows the mean 1,000-, 10,000-, and 100,000-year return period mean reference rock uniform hazard response spectra (UHRS) for the VCSNS site utilizing the EPRI GMM (blue) and the NGA-East GMM (red). This comparison between the UHRS for the two GMMs shows the results from using the ergodic standard deviation for both the EPRI GMM and for the NGA-East GMM, which is appropriate because, as discussed below, VCSNS is a reference condition rock site. As shown in Figure 5, the spectral accelerations which use the NGA-East GMM are moderately higher at the 10-4 and 10-5 AFE levels as compared to the EPRI GMM up to the spectral frequency of about 25 Hertz (Hz).
4.2 Site Response Analysis SRAs, which are used to develop site amplification factors (SAFs) depend on several factors, including the site strata (i.e., material type, stiffness, and thickness) and their response to dynamic loading. Because this information is site-specific, the ability to accurately model the site response depends on the quantity and quality of site-specific geologic and geotechnical data available, and on the interpretation and use of the data to develop input models for assessing amplification (or deamplification) of ground motions. The resulting SAFs are assessed for a wide range of input ground motions as part of understanding the changes in the soil and rock response as input ground motions increase.
4.2.1 Site Exploration As described in the NTTF R2.1 SHSR submitted by South Carolina Electric & Gas (SCE&G; Gatlin, 2014) 3 and summarized in Section 2.3.14 of NUREG/KM-0017, the site investigations for VCSNS consisted of numerous geophysical, geotechnical and laboratory measurements from the siting investigations for Unit 1 and for proposed Units 2 and 3 (SCE&G, 2011), located adjacent to Unit 1.
4.2.2 Base Case Profiles In its SHSR (Gatlin, 2014), SCE&G stated that the rock underlying the VCSNS site is crystalline igneous rock (i.e., granodiorite and quartz diorite) and that the shear wave velocity () at the control point elevation, located at the foundation for Seismic Category 1 structures, is close to the reference rock of 2,830 m/sec assumed by the EPRI GMM. As such, SCE&G did not perform an SRA to determine the GMRS. Based on its evaluation of the values from the borehole geophysical surveys for the VCSNS site which were performed for proposed Units 2 and 3 (SCE&G, 2011), the NRC staff estimated a rock of about 2,800 m/sec for the foundation level, which is similar to the reported by SCE&G in its SHSR (Gatlin, 2014).
Although the reference rock for the NGA-East GMM is 3,000 m/sec is slightly higher than the reference rock velocity used for the EPRI GMM, the NRC staff concluded that an SRA for the VCSNS site will produce close to 1 at the ground motion amplitudes associated with the GMRS and, as such, have no impact on the final GMRS for the site. Therefore, for this seismic hazard re-evaluation, the NRC staff did not perform an SRA.
4.3 Control Point Hazard and Ground Motion Response Spectra To determine the GMRS for the VCSNS site, the NRC staff used the 10-4 and 10-5 UHRS, shown in Figure 5 of Section 8 of this Seismic Hazard Report, developed from the reference rock hazard curves. Table 1 in Section 8 shows the 10-4 and 10-5 UHRS and the GMRS spectral acceleration values for the VCSNS site. Figure 6 shows the GMRS (red curve) compared to the GMRS (blue curve) developed by SCE&G for its SHSR (Gatlin, 2014). As shown in Figure 6, the final GMRS from this study is very similar in shape but moderately higher (24 percent at 5 Hz) than the SCE&G GMRS between 1 and 10 Hz. Above 10 Hz, the EPRI GMM was developed for only two additional oscillator frequencies at 25 Hz and 100 Hz. Therefore, the shape of the SCE&G GMRS above 10 Hz was developed assuming a generic spectral shape for CEUS hard rock sites, provided in NUREG/CR-6728, Technical Basis for Revision of Regulatory Guidance on Design Ground Motions: Hazard-and Risk-consistent and Ground Motion Spectra Guidelines, issued October 2001 (McGuire et al., 2001). In contrast, the NGA-East GMM was developed for 23 oscillator frequencies and, therefore, the GMRS developed from this study does not rely on a generic CEUS spectral shape above 10 Hz. The higher spectral accelerations for the GMRS developed from this study are due to the NGA-East GMM, which predicts higher median ground motions for sites where the hazard is controlled by higher-magnitude but distant earthquakes (i.e., RLMEs) relative to the EPRI GMM (see Figures 4 and 5).
5.0 Data Tables Appendix A provides the data tables for the VCSNS site. Tables A-1, A-2, and A-3 give the reference rock mean hazard curves for 23 spectral frequencies ranging from 0.1 to 100 Hz and 3 On January 2, 2019, Dominion Energy purchased the Virgil C. Summer Nuclear Station from SCANA Corporation, the parent company of South Carolina Electric & Gas.
for peak ground acceleration (PGA). As described above in Section 4.2.2 of this Seismic Hazard Report, the NRC staff did not perform an SRA for the VCSNS hazard reevaluation. As such, the reference rock mean hazard curves and control point mean hazard curves are the same for VCSNS.
