3.7 EMERGENCY LIGHTING 3.

7.1 INTRODUCTION

The emergency lighting facilities at the Turkey Point Plant provide illumination in areas needed for operation of safe shutdown equipment, as well as access and egress routes thereto in the event that normal lighting is unavailable. In addition, the emergency lighting facilities have been designed to provide for personnel safety, based on prudent engineering judgement.

3.7.2 DESIGN BASES The design of the Emergency Lighting facilities is based on the guidancetpequirements set forth in 10 CFR 50 Appendix R, section III.J and Appendi3 A to BTP 9.5-1. The following are specific design criteria:

a) Lighting shall be provided for personnel safety and general access/egress.

b) sealed beam lighting units with eight hour minimum battery power supplies shall be provided for hot standby equipment requiring local operator action, and access/egress routes thereto.

c) Dedicated portable sealed beam battery-operated lighting units, stored in fire cabinets outside the containment, shall be provided for containment entry if operation of valves in the containment is necessary to achieve or maintain cold shutdown.

d) The control Room Emergency Lighting shall be available and of sufficient intensity for safe shutdown from the control Room with a fire in a single fire area coincident with a loss of offsite power.

e) Dedicated portable battery-powered lighting units with an eight hour nominal rated battery supply shall be provided in designated storage lockers. These lights are to provide required lighting for access, egress and manual actions.

7.3 DESCRIPTION

The battery pack emergency lighting facilities are wired to the plant electrical lighting system and automatically maintain the battery in a ready state. In the event of a loss of AC power, the unit automatically turns the emergency lights on. upon restoration of power the unit automatically turns off the emergency lights and places them on charge.

Equipment and access routes are illuminated to enable the operator to perform specific actions and negotiate the paths safely. In addition, other emergency lighting units are installed for personnel safety, based on prudent engineering judgement, and are not associated with Appendix R requirements.

see Reference 20 for a tabulation of Appendix R - required emergency lighting units. Refer to Figures 9.6A-12 through 9.6A-15 for the locations of emergency lighting.

The emergency lighting units are installed in accordance with the vendor's instructions and the applicable design documents. The units are seismically mounted where required.

The 1-1/2 inch drain lines can accommodate a gravity induced flow rate in excess of 14 gpm. This flow rate exceeds the maximum expected leakage rate of 10 gallons per year for each pump (Reference 33) and exceeds the 10 gpm flow rate expected from an RCP lube oil lift pump discharge line break.

An exemption was granted from that portion of 10 CFR 50, Appendix R section III.0, which requires an oil collection tank to be capable of containing the lube oil inventory of all three reactor coolant pump motors. (Refer to section 4.0 of this Appendix.)

.3.11 FIRE RATED ASSEMBLIES - BARRIERS 3 .

11.1 INTRODUCTION

Fire barriers at Turkey Point Units 3 and 4 are provided as part of the protection to ensure that the function of one set of redundant safety-related equipment necessary to achieve and maintain hot standby conditions remains free of fire damage. Fire barriers provide a means of limiting fire travel by compartmentalization and containment. In some cases written evaluations approved by a Fire Protection Engineer may be kept on file to demonstrate acceptability of a fire rated assembly or barrier. (Reference NRC Generic Letter 86-10 paragraph C.)

3.11.2 WALLS, FLOORS AND CEILINGS 3.11.2.1 Design Bases a) Pursuant to Appendix R section III.G.2(a), walls, floors and ceilings separating Fire Areas shall be fire barriers with a minimum rating of three hours as defined by ASTM E-119 (e.g. six inch solid concrete or greater, 8 inch concrete filled concrete block or greater; Thermo-lag thickness per engineering design output).

b) walls, floors and ceilings installed as fire barriers shall be designed to maintain the class of the structure (refer to FSAR Appendix 5A) and to preclude damage to nearby safety related equipment.

c) FPL requested exemptions (Reference 4) from the NRC for fire rated doorsand dampers in exterior wall penetrations in the Auxiliary Building, control Building, Unit 3 Diesel Generator Building and Switchgear Buildings. The NRC determined (Reference 6) that since the exterior walls in question did not separate redundant safe shutdown equipment and no fire hazards existed within 50 feet of the buildings, no deviations were required. Therefore, exterior walls do not require openings to be protected by 3-hour rated fire doors, fire dampers or penetration seals provided those walls do not serve to separate redundant safe shutdown equipment or circuits and no exterior fire hazards exist within 50 feet of the building.

3.11.2.2 Description The plant is divided into fire zones, which are grouped into Appendix R Fire Areas. Fire Areas are separated from each other by rated fire barriers.

These barriers are shown on Figures 9.6A-8 through 9.6A-11. The composition of these barriers is described for each fire zone in section 4.0 of this Appendix.

9.6A-104 Rev. 17

. i Floor slabs which rest on soil foundations and earthbound walls may be designated as fire barriers but due to their underground nature will not be required to have a specific fire rating.

The unit 3 or unit 4 containment wall forms a portion of the fire barrier for several fire areas. Although the containment wall is not a tested configuration for fire barriers, its construction is of such substantial integrity as to justify its use as a three hour rated fire barrier.

Exemption MM.'2 see section.3.11.2 .1 c) justification for Exemption The control Room is an area that is continuously manned in accordance with existing technical specifications. This assures that any fire occurring within the control Roo will be auicklv detcte n CL Inn In accordance with the requirements of 10 CFR Part 50 Appendix R sections III.L, alternate shutdown remote from the control Room will be provided.

The in situ combustibles in the Control Room consist of cables and components located within control boards, panels and control consoles and miscellaneous paper in the form of books, manuals and computer printouts.

A review of potential transient combustibles for this fire area was conducted by the Factory Mutual Research corporation for FPL.- The results of this review indicate that there are no expected transient combustibles for this fire area.

Fire protection features existing for this fire area are active and passive in nature. Passive fire protection is provided by the steel cabinets and control consoles which serve to contain in situ combustibles in discrete quantities and the spatial separation between consoles and cabinets.

Active fire protection is provided by the installed fire detection system which will provide early warning of any fire in this area allowing the operators to respond before significant development occurs, and by the continuous presence of operators in this area.

In conclusion, it is FPL'S position that the alternate shutdown system and the existing fire protection features combined with the continuous manning of this area provide a level of fire protection consistent with the fire hazards, both in situ and transient identified for this fire area and that these features provide assurance that at least one train of safe shutdown equipment and cables will be free of fire damage.
