Enclosure 1, Item (9) of the 50.54(f) letter requested addressees to prqvide limited scope Spent Fuel Pool (SFP) evaluations. By letter dated October 27, 2015 (Reference 2), the NRC transmitted final seismic information request tables which identified that Catawba Nuclear Station is to conduct a limited scope SFP Evaluation. By Reference 3, Nuclear Energy Institute (NEI) submitted an Electric Power Research Institute (EPRI) report entitled, Seismic Evaluation Guidance Spent Fuel Pool Integrity Evaluation (EPRI 3002007148) (Reference 4) for NRC review and endorsement. NRC endorsement was provided by Reference 5.
EPRI 3002007148 provides criteria for evaluating the seismic adequacy of a SFP to the reevaluated ground motion response spectrum (GMRS) hazard levels. This report supplements the guidance in the Seismic Evaluation Guidance, Screening, Prioritization, and Implementation Details (SPID) (Reference 8), for plants where the GMRS peak spectral acceleration is less than or equal to 0.8g. Section 3.3 of EPRI 3002007148 lists the parameters to be verified to confirm that the results of the report are applicable to Catawba Nuclear Station and that the Catawba Nuclear Station SFP is seismically adequate in accordance with the Near-Term Task Force (NTTF) 2.1 Seismic evaluation criteria.
The attachment to this letter provides the data for Catawba Nuclear Station that confirms applicability of the EPRI 3002007148 criteria, confirms that the SFP.is seismically adequate, and provides the requested information in response to Item (9} of the 50.54 (f) letter associated with NTTF Recommendation 2.1 Seismic evaluation criteria.
This letter contains no new Regulatory Commitments and no revision to existing Regulatory Commitments.

Docket Numbers 50-413 and 50-414 Renewed License Numbers NPF-35 and NPF-52 Site-Specific Spent Fuel Pool Criteria for Catawba Nuclear Station, Units 1 and 2
The 50.54(f) letter requested that, in conjunction with the response to Near-Term Task Force (NTTF) Recommendation 2.1, a seismic evaluation be made of the Spent Fuel Pool (SFP).
More specifically, plants were asked to consider "all seismically induced failures that can lead to draining of the SFP." Such an evaluation would be needed for any plant in which the ground motion response spectrum (GMRS) exceeds the safe shutdown earthquake (SSE) in the 1 to 10 Hz frequency range. The staff confirmed through References 2 and 7 that the GMRS exceeds the SSE and concluded that a SFP evaluation is merited for the Catawba Nuclear Station. By letter dated March 17, 2016 (Reference 5), the staff determined that the Electric Power Research Institute (EPRI) 3002007148 was an acceptable approach for performing SFP evaluations for plants where the peak spectral acceleration is less than or equal to 0.8g.
The table below lists the criteria from Section 3.3 of EPRI 3002007148 along with data for Catawba Nuclear Station that confirms applicability of the EPRI 3002007148 criteria and confirms that the SFP is seismically adequate and can retain adequate water inventory for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in accordarce with NTTF 2.1 Seismic evaluation criteria. 1 Site Parameters
