FACILITY: H. B. Robinson Steam Electric Plant Unit No. 2
SUBJECT:
SUMMARY
OF THE H. B. ROBINSON STEAM ELECTRIC PLANT UNIT NO. 2 - SEPTEMBER 22 - 26, 2014, AUDIT ASSOCIATED WITH LICENSE AMENDMENT REQUEST TO TRANSITION TO THE NATIONAL FIRE PROTECTION ASSOCIATION 805 STANDARD (CAC NO. MF2746)
By letter dated September 16, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13267A211), Duke Energy Progress, Inc. (Duke Energy), the licensee, for the H. B. Robinson Steam Electric Plant Unit No. 2 (Robinson), submitted a license amendment request (LAR) to adopt a new fire protection licensing basis that complies with the requirements of Title 10 of the Code of Federal Regulations, Sections 50.48(a) and (c); the guidance in Regulatory Guide 1.205, Revision 1, "Risk-Informed, Performance-Based Fire Protection for Existing Light-Water Nuclear Power Plants"; and National Fire Protection Association (NFPA) 805, "Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants" (2001 Edition). The purpose of this summary is to document the results of the audit performed at Robinson associated with this LAR.
An audit team, consisting of U.S. Nuclear Regulatory Commission (NRC) staff and contractors from the Pacific Northwest National Laboratories (PNNL) and Southwest Research Institute (SwRl)/Center for Nuclear Waste Regulatory Analyses (CNWRA) conducted a regulatory audit of Robinson, which occurred during September 22 - 26, 2014, at the Duke Energy offices in Charlotte, North Carolina. The purpose of the audit was to understand what information the NRC staff needed to support its review of the LAR and to develop requests for additional information as needed. The information submitted in support of the LAR is under final review, and the staff will request any additional information needed to support its review in accordance with NRC Office of Nuclear Reactor Regulation, Office Instruction LIC-101, "License Amendment Review Procedures" (ADAMS Accession No. ML113200053).
The audit team consisted of ten NRC staff, three PNNL staff, and one CNWRA staff. provides the schedule of activities during the audit. Enclosure 2 lists NRC staff, PNNL staff, CNWRA staff, and the licensee's staff and contractors that participated in the audit. contains a list of documents reviewed by the team. The audit plan, dated September 4, 2014, is available in ADAMS at Accession No. ML14246A509.
The audit team held an entrance meeting with the licensee's staff and contractors on September 22, 2014. During the remainder of the audit, the licensee's staff provided plant walkdowns and presentations on fire protection engineering, post-fire safe shutdown circuit analysis, fire probabilistic risk assessment, and fire modeling. NRC and licensee discussions focused on these subjects and on fire protection programmatic review.
At the conclusion of the audit, the NRC's audit team participated in a summary exit meeting with the licensee's staff and management on September 25, 2014.
