UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 June 11, 2015 Mr. William R. Gideon Vice President Brunswick Steam Electric Plant P.O. Box 10429 Southport, NC 28461

SUBJECT:

NUCLEAR REGULATORY COMMISSION PLAN FOR THE AUDIT OF DUKE ENERGY PROGRESS, INC.'S FLOOD HAZARD REEVALUATION REPORT SUBMITTAL RELATING TO THE NEAR-TERM TASK FORCE RECOMMENDATION 2.1-FLOODING FOR BRUNSWICK STEAM ELECTRIC PLANT, UNITS 1AND2 (TAC NOS. MF6104 AND MF6105)

Dear Mr. Gideon:

This letter documents the U.S. Nuclear Regulatory Commission (NRC) staff's plan to perform a regulatory audit of Duke Energy Progress lnc.'s (the licensee) supporting calculations for the Flood Hazard Reevaluation Report (FHRR) submittal related to the Near-Term Task Force Recommendation 2.1, Flooding for Brunswick Steam Electric Plant, Units 1 and 2 (Brunswick).

This technical audit will be performed consistent with NRC Office of Nuclear Reactor Regulation, Office Instruction LIC-111, "Regulatory Audits," dated December 29, 2008 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML082900195). The audit will be conducted over multiple sessions, as needed, and the NRC staff will develop an audit summary report to document its observations and conclusions within 90 days of the final audit session.

The audit will provide the NRC staff with a better understanding of the Brunswick FHRR, which was submitted March 11, 2015 (ADAMS Accession No. ML15079A385). Specifically, the audit will provide the NRC staff with a better understanding of the analyses (and supporting documentation) of the flooding hazards presented in the Brunswick FHRR. The audit is intended to support completion of the staff's review of the FHRR and the subsequent issuance of a Staff Assessment.

The enclosed audit plan outlines the process that will allow the NRC staff to identify additional information potentially necessary for licensees to supplement their FHRRs, and resolve potential technical concerns. The details of this audit have been discussed with Mr. Phil Ballard of your staff.

W. Gideon If you have any questions, please contact me at (301) 415-3809 or by e-mail at Juan.Uribe@nrc.gov.
