SUMMARY

OF SITE AUDIT TO SUPPORT THE REVIEW OF A LICENSE AMENDMENT REQUEST FOR VIRGIL C. SUMMER NUCLEAR STATION, UNIT 1, TO TRANSITION TO THE NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 805 FIRE PROTECTION LICENSING BASIS (TAC NO. ME7586)

The purpose of this summary is to document the results of an audit performed at Virgil C.

Summer Nuclear Station (VCSNS), Unit 1, associated with a National Fire Protection Standard 805 (NFPA 805) license amendment requested (LAR) dated November 15, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML11321A172), as supplemented.

A review team, consisting of U.S. Nuclear Regulatory Commission (NRC) staff and contractors from the Center for Nuclear Waste Regulatory Analyses (CNWRA) and the Pacific Northwest National Laboratories (PNNL) participated in a regulatory audit of VCSNS, Unit 1, located in Jenkinsville, SC from June 4 to 8, 2012. The regulatory audit supported the review of the LAR filed by South Carolina Electric and Gas Company, to transition the plant's fire protection licensing basis to Title 10 of the Code of Federal Regulations Part 50.48(c), which endorses with exceptions the 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 staff's licensing decision regarding the LAR and to develop requests for additional information (RAI), as needed.

The audit team consisted of 1 O NRC, 3 CNWRA (NRC contractor), and 1 PNNL (NRC contractor) staff, of which 1 NRC staff member was an audit observer. Enclosure 1 provides the schedules of activities during the audit. Enclosure 2 lists the NRC staff, the CNWRA staff, the PNNL staff, the licensee staff, and the licensee contractors who participated in the audit.

The Audit Team held an entrance meeting on Monday, June 4, 2012, with the licensee staff anp contractors, licensee management and NRC resident inspectors. During the remainder of the audit, team members met in smaller groups according to the Audit Plan. VCSNS staff provided plant walkdowns focusing on fire protection engineering, safe shutdown, fire probaqilistic risk assessment (PRA), and fire modeling.

Technical discussions were focused on five major areas: fire protection engineering, post-safe shutdown/circuit analysis, fire PRA, fire modeling, and programmatic review. Documents reviewed during the audit were made previously available on the VCSNS reference portal and some additional documents were placed on the portal based on discussions during the audit. contains a list of documents that were made available for review on the portal during the audit. In addition, hard copies that were reviewed during the audit are presented in this enclosure.

At the conclusion of the audit, the audit team participated in a summary exit meeting with VCSNS staff and management on June 8, 2012. The NRG staff expressed its appreciation to the VCSNS staff for providing informative walkdowns and presentations for the regulatory audit team.
