On March 12, 2012, the Nuclear Regulatory Commission (NRG) issued a request for information (Reference 1) pursuant to 10 CFR 50.54(f) to all power reactor licensees and holders of construction permits in active or deferred status. Enclosure 1 of the 10 CFR 50.54(f) letter requests each addressee located in the Central and Eastern United States (CEUS) to submit a Seismic Hazard Evaluation and Screening Report.

In accordance with the Screening, Prioritization, and Implementation Details (SPID) report and Augmented Approach guidance endorsed by the NRG staff (References 2, 3, and 4), PSEG Nuclear LLC (PSEG) provided the requested report for Hope Creek Generating Station (HCGS) on March 28, 2014 (Reference 5). The purpose of this letter is to complete PSEG's Commitment No. 1 in Reference 5 to perform a relay chatter review for HCGS, consistent with the NRG screening and prioritization results (Reference 6) and subsequent NRG-endorsed guidance for completing high frequency confirmations (References 7 and 8).

The reevaluated seismic hazard (Reference 5) is used to determine if additional seismic risk evaluations are warranted for a plant. Specifically, the reevaluated horizontal ground motion response spectrum (GMRS) at the control point elevation is compared to the existing safe shutdown earthquake (SSE) to determine if a plant is required to perform a high frequency confirmation. The NRG screening and prioritization letter (Reference 6) identified HCGS as a plant that is required to conduct a limited scope high frequency evaluation and acknowledged that the schedule milestones and content

DEC 2 3 2015 10 CFR 50.54(f)

Page 3 LR-N15-0256 of limited scope evaluations will require additional development of the assessment process. By Reference 7, Nuclear Energy Institute (NEI) submitted an Electric Power Research Institute (EPRI) report containing high frequency confirmation guidance that was endorsed by the NRC staff in Reference 8. PSEG performed the high frequency confirmation in lieu of the relay chatter evaluation, consistent with References 6, 7, and 8.

The high frequency confirmation for HCGS shows that the GMRS exceedance area between the control point GMRS and SSE is 7% of the area under the SSE design basis response spectrum in the region of the exceedance. As such, the GMRS exceedance area is consistent with the high frequency confirmation screening criteria in Section 3.1.2 of Reference 7. Therefore, no additional evaluation is necessary. to this letter provides the SSE response spectrum and the GMRS information from Reference 5.

This transmittal completes Commitment No. 1 from Reference 5. There are no regulatory commitments contained in this letter.

If you have any questions or require additional information, please do not hesitate to contact Mr. Lee Marabella at 856-339-1208.

I declare under penalty of perjury that the foregoing is true and correct.
