SUBJECT:
NUCLEAR REGULATORY COMMISSION PLAN FOR THE AUDIT OF OMAHA PUBLIC POWER DISTRICT'S FLOOD HAZARD REEVALUATION REPORT SUBMITTAL RELATING TO THE FUKUSHIMA NEAR-TERM TASK FORCE RECOMMENDATION 2.1-FLOODING FOR FORT CALHOUN STATION, UNIT 1 (TAC NO. MF4711)
Dear Mr. Cortopassi:
This letter documents the U.S. Nuclear Regulatory Commission (NRC) staff's plan to perform a regulatory audit of Omaha Public Power District's (the licensee) Flood Hazard Reevaluation Report (FHRR) submittal related to the Fukushima Near-Term Task Force Recommendation 2.1, Flooding for Fort Calhoun Station, Unit 1 (Fort Calhoun). 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 with a better understanding of the Fort Calhoun FHRR which was submitted on February 4, 2015 (ADAMS Accession No. ML15042A127). Specifically, the audit will provide the NRC with a better understanding of the analyses of the flooding hazards presented in the Fort Calhoun 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 necessary for the staff to complete the FHRR review. The details of this audit have been discussed with Mr. Joe Wiegand of your staff.
If you have any questions, please contact me at (301) 415-6197 or by e-mail at Tekia.Govan@nrc.gov.

By letter dated March 12, 2012, the U.S. Nuclear Regulatory Commission (NRC) issued a request for information to all power reactor licensees and holders of construction permits in active or deferred status, pursuant to Title 1 O of the Code of Federal Regulations (10 CFR),
Section 50.54(f) "Conditions of license" (hereafter referred to as the "50.54(f) letter). The request was issued in connection with implementing lessons-learned from the 2011 accident at the Fukushima Dai-ichi nuclear power plant, as documented in The Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident. Recommendation 2.1 of that document recommended that the staff issue orders to all licensees to reevaluate seismic and flooding for their sites against current NRC requirements and guidance. Subsequent Staff Requirements Memoranda associated with Commission Papers SECY 11-0124 and SECY-11-0137, instructed the NRC staff to issue requests for information to licensees pursuant to 10 CFR 50.54(f).
By letter dated February 4, 2015, Omaha Public Power District (OPPD, the licensee) submitted its Flood Hazard Reevaluation Report (FHRR) for Fort Calhoun Station, Unit 1 (Fort Calhoun)
(Agencywide Documents Access and Management System (ADAMS) Accession No. ML15042A127). The NRC staff has begun its review of the aforementioned submittal and plans to conduct a regulatory audit of OPPD to aid in its review of the licensee's FHRR.
