?.. NRG Letter, Final Determination of Licensee Seismic Probabilistic Risk Assessments under the Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f)

Regarding Recommendation 2. 1 "Seismic" of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident, dated October 27, 2015, ADAMS Accession Number ML15194A015 Ladies and Gentlemen, On March 12, 2012, the Nuclear Regulatory Commission (NRG) issued a Request for Information per 10 CFR 50.54(f) (i.e., Reference 1) to all power reactor licensees. The required response section of Enclosure 1 to that request indicated that licensees should provide a Seismic Hazard Evaluation and Screening Report within 1.5 years from the date of the letter for Central and Eastern United States (CEUS) nuclear power plants. By NRG letter dated May 7, 2013 (i.e., Reference 2), the date to submit the report was extended to March 31, 2014.

Reference 3 contains industry guidance and detailed information to be included in the Seismic Hazard Evaluation and Screening Report submittals. The industry guidance was endorsed by the NRG in Reference 4. In accordance with the screening, prioritization, and implementation details report (SPID) and Augmented Approach guidance (i.e., References 2, 3, and 4), the reevaluated seismic hazard is used to determine if additional seismic risk evaluations are warranted for a plant.

By letter dated March 31, 2014 (i.e., Reference 5), Duke Energy, LLC, submitted the Seismic Hazard Evaluation and Screening Report for the Brunswick Steam Electric Plant (BSEP), Unit Nos. 1 and 2. By letter dated May 9, 2014 (i.e., Reference 6), the NRG transmitted the results of the screening and prioritization review of the seismic hazards reevaluation for all power reactor.licensees including BSEP, Units 1 and 2.

By letter dated October 27,' 2015 (i.e., Reference 7), the NRG transmitted the Final Determination of Licensee Seismic Probabilistic Risk Assessments under the request for information for BSEP, Units 1 and 2. As noted in the October 27, 2015, NRG letter, BSEP is to conduct an Individual Plant Examination of External Events (IPEEE) relay review.

The purpose of this letter is to inform the NRG that the IPEEE relay review for BSEP, Unit Nos. 1 and 2, is complete.

This letter contains no new Regulatory Commitments.

If you have any questions regarding this submittal, please contact Mr. Lee Grzeck, Manager - Regulatory Affairs, at (910) 457-2487.
