Fire Detection Instrumentation 16.9.6 BASES On June 16, 2004, the NRC revised its regulation Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 50.48 to include a new paragraph 50.48(c) that incorporates by reference National Fire Protection Association 805, "Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants 2001 Edition," hereafter referred to as NFPA 805. On December 29, 2010, the NRC issued Oconee's Safety Evaluation Report (SER) approving adoption of a performance-based (PB) fire protection program (FPP) as an alternative to the existing, deterministic fire protection regulations. Specifically, NFPA 805 allows the use of PB methods, such as fire modeling, and risk-informed (RI) methods, such as fire probabilistic risk assessment (PRA), to demonstrate compliance with the nuclear safety performance criteria. As a result of transitioning to the NFPA 805 Licensing Basis, certain Fire Protection Systems and Features are "required" to satisfy either the NFPA 805 Chapter 3 fundamental fire protection program safety goals or the NFPA 805 Chapter 4 performance based/risk informed safety goals. These "required" Fire Protection Systems and Features are placed into SLCs since they comprise the safety basis of the new fire protection program.

Allowed out ofservice times and action stat.ements along with some surveillance requirements are consistent with the NFPA 805 licensing basis and safety goals. The documentation of these "required" fire protection systems and features is provided in the SER Attachments A and D.

The equipment contained in this SLC is considered part of the NFPA 805 Power Block. Power Block structures, systems, and components (SSCs) include all safety-related and balance-of-plant systems and components required for operation, including radioactive waste processing and storage, the 230 kV switchyard, and Keowee Dam and associated structures. Power Block SSCs are required for the safe and reliable operation of the plant. Calculation OSC-10650, Oconee NFPA 805 Power Block, defines the Power Block for Oconee. Not all fire detection within the Power Block is required by this SLC. Only the Power Block detection listed in Table 16.9.6-1 herein is within the scope of this SLC.

DPC-1435.00-00-0002, Technical Basis for Roving Continuous Fire Watches, justifies the allowances for continuous and hourly fire watches. This Selected Licensee Commitment is part of the Oconee Fire Protection Program and therefore subject to the provisions of Oconee Facility Operating License Conditions.

ACTIONS FUNCTIONALITY of the NRC committ~d Fire Detection Instrumentation ensures that adequate warning capability is available for the prompt detection of fires in areas containing safety related and important to safety equipment at Oconee Facilities. Prompt detection of fires will reduce the potential for damage to safety related equipment and is an integral element in the overall facility fire protection program. The regulatory requirement is to have NFPA 805 required Fire Detection Instrumentation FUNCTIONAL at all times.

16.9.6-10 Rev. 003 I

Fire Detection Instrumentation 16.9.6 A.1 and B.1 In the event that a portion of the Fire Detection Instrumentation is nonfunctional, the establishment of compensatory actions in the affected areas is required to provide detection capability until the nonfunctional instrumentation is restored to FUNCTIONALITY.

RA B.2 provides an option for times when fire watches may not be the most effective compensatory measure for degraded or inoperable fire protection features. To implement a different compensatory measure or combination of measures, perform a documented evaluation of the impact of the proposed alternate compensatory measure. The evaluation must demonstrate that the alternate compensatory measure would not adversely affect the ability to achieve and maintain safe shutdown in the event of a fire. Additionally, the evaluation of the alternate compensatory measure should incorporate risk insights regarding the location, quantity, and type of combustible material in the fire area; the presence of ignition sources and their likelihood of occurrence; the automatic fire suppression and fire detection capability in the fire area; the manual fire suppression capability in the fire area; and the human error probability where applicable. Retain all such evaluations in accordance with 10 CFR 50.48(a}. Refer to RIS 2005-07 for additional information.
