SUMMARY
OF SITE AUDIT TO SUPPORT THE REVIEW OF A LICENSE AMENDMENT REQUEST FOR ARKANSAS NUCLEAR ONE, UNIT 2 TO TRANSITION TO THE NATIONAL FIRE PROTECTION ASSOCIATION (NFPA) STANDARD 805 FIRE PROTECTION LICENSING BASIS (TAC NO. MF0404)
A review team, consisting of U.S. Nuclear Regulatory Commission (NRC) staff and contractors from the Pacific Northwest National Laboratory (PNNL) and Southwest Research Institute (SwRI)/Center for Nuclear Waste Regulatory Analyses (CNWRA) participated in a regulatory audit of the Arkansas Nuclear one unit 2, (ANO2) located in Russellville, AK from July 15 -18 ,
2013. The regulatory audit supports the review of the license amendment request (LAR) dated December 17, 2012, filed by Entergy Operations, Inc. (Entergy) to transition the plants fire protection licensing basis to Title 10 of the Code of Federal Regulations (CFR) 50.48(c), which endorses with exceptions the National Fire Protection Association (NFPA) Standard 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants, 2001 Edition.
The purpose of the audit was to gain an understanding of the information needed to support the staffs licensing decision regarding the LAR and to develop high quality requests for additional information (RAI), as needed. The information submitted in support of the ANO2 LAR is under final review, and any additional information needed to support the LAR review will be formally requested by the staff in accordance with Office of Nuclear Reactor Regulation Office Instruction LIC-101, License Amendment Review Procedures.

E. Oesterle 2 The audit team consisted of 11 NRC, 3 PNNL and 3 CNWRA (NRC contractors) staff. provides the schedules of activities during the audit. Enclosure 2 lists NRC staff, PNNL staff, CNWRA staff, and the licensees staff, and contractors who participated in the audit.
The audit team held an entrance meeting on Monday, July 15, 2013, with the licensees staff and contractors. During the remainder of the audit, team members met in smaller groups according to the audit plan (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13178A325). ANO2 staff provided plant walk-downs focusing on fire protection engineering (FPE), safe shutdown (SSD), fire probabilistic risk assessment (PRA), and fire modeling.
Technical discussions were focused on five major areas: FPE, SSD/circuit analysis (CA), fire PRA, fire modeling, and programmatic review. Enclosure 3 contains a list of documents reviewed by the team. In addition, attendance lists for entrance and exit meetings are provided in Enclosure 4 (ADAMS Accession Nos.: ML14356A180 and ML14356A185). At the conclusion of the audit, the audit team participated in a summary exit meeting with ANO2 staff and management on July 18, 2013. NRC staff expressed its appreciation to the ANO2 staff for providing informative walk-downs and presentations for the regulatory audit team.
