Contact:

Alan Holder Phone: 919-546-3372 Email: alan.holder@pgnmail.com Distribution: (NEI Internal Use) 805 TF FPWG FPRATF Purpose of FAQ:

FAQ seeks clarification to define the minimum acceptable scope and content for Pre-Fire Plans.

Is this Interpretation of guidance? Yes / No Proposed new guidance not in NEI 04-02? Yes / No Details:

NEI 04-02 guidance needing interpretation (include section, paragraph, and line numbers as applicable):

NEI 04-02, Section 4.3.1, Fundamental Fire Protection Program and Design Elements Transition Review, should refer to a new appendix which lists interpretation of specific sections of NFPA 805 Chapter 3 Circumstances requiring guidance interpretation or new guidance:

Clarification of NFPA-805, Standard for Fire Protection for Light Water Reactor Electric Generating Plants (2001 Edition), Chapter 3, Section 3.4, Industrial Fire Brigade, section 3.4.2.1, The plans shall detail the fire area configuration and fire hazards to be encountered in the fire area, along with any nuclear safety components and fire protection systems and features that are present.

Due to the variance in formats, level of detail and content found in current pre-fire plans, desire for standardization and ease of product quality assessment and regulatory enforcement indicates the need for further guidance. Specifically, define the minimum acceptable scope and content for Pre-Fire Plans.

Proposed resolution of FAQ and the basis for the proposal:

This FAQ seeks to define minimum acceptable pre-fire plan scope and content. Current guidance is found in regulatory documents such as 10CFR50, Appendix R, Section K, NUREG 0800 Section BTP CMEB 9.5-1 Rev 3 July 1981 Section 9.5.1 C.2(o) and Generic Letter 77-02 (FRAQA letter).

FAQ Number 06-0025 FAQ Revision 5 FAQ Title Scope and Content of Pre-Fire Plans If appropriate, provide proposed rewording of guidance for inclusion in the next Revision:

Clarification of specific sections of NFPA 805 as applied under 10 CFR 50.48(c), will be included in a new Appendix K, to NEI 04-02 (final formatting to be provided by NEI).

Include the following information in Appendix K:

NFPA 805, Section 3.4 Clarification:

As a minimum, the pre-fire plans should define the strategies for fighting fires in all areas in which a fire could jeopardize the ability to meet the performance criteria described in Section 1.5. These pre-fire plans should designate:

• Fire hazards in each area covered by the specific pre-fire plans.

• Fire extinguishants best suited for controlling the fires associated with the fire hazards in that area and the nearest location of these extinguishants.

• Most favorable direction from which to attack a fire in each area in view of the ventilation direction, access hallways, stairs, and doors that are most likely to be free of fire, and the best station or elevation for fighting the fire. All access and egress routes that involve locked doors should be specifically identified in the procedure with the appropriate precautions and methods for access specified.

• Plant systems that should be managed to reduce the damage potential during a local fire and the location of local and remote controls for such management (e.g., any hydraulic or electrical systems in the zone covered by the specific fire fighting procedure that could increase the hazards in the area because of overpressurization or electrical hazards).

• Vital heat-sensitive system components that need to be kept cool while fighting a local fire. Particularly hazardous combustibles that need cooling should be designated.

• Organization of fire fighting brigades and the assignment of special duties according to job title so that all fire fighting functions are covered by any complete shift personnel complement. These duties include command control of the brigade; transporting fire suppression and support equipment to the fire Deleted: p scenes, applying the extinguishant to the fire, communication with the control room, and coordination with outside fire departments.
