SUBJECT:
NUCLEAR REGULATORY COMMISSION PLAN FOR THE AUDIT OF ENTERGY OPERATIONS, INC.'S FLOOD HAZARD REEVALUATION REPORT SUBMITTAL RELATING TO THE NEAR-TERM TASK FORCE RECOMMENDATION 2.1-FLOODING FOR ARKANSAS NUCLEAR ONE, UNITS 1 AND 2 (CAC NOS. MF8380 AND MF8379)
Dear Sir or Madam:
This letter documents the U.S. Nuclear Regulatory Commission (NRC) staff's plan to perform a regulatory audit of Entergy Operations, lnc.'s (the licensee) supporting calculations of the Flood Hazard Reevaluation Report (FHRR) submittal related to the Near-Term Task Force Recommendation 2.1 for Arkansas Nuclear One, Units 1 and 2 (ANO). 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 ANO FHRR, which was submitted on September 14, 2016 (ADAMS Accession No. ML 16260A060). Specifically, the audit will provide the NRC with a better understanding of the analyses of the flooding hazards presented in the ANO 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 that may be necessary for licensees to supplement their FHRRs, and resolve any technical concerns. The details of this audit have been discussed with Mr. Donald Bentley of your staff. If you have any questions, please contact me at (301) 415-2621 or by e-mail at Robert.Bernardo@nrc.gov. Docket Nos. 50-313 and 50-368
