In addition, fixed fire suppression systems are installed as required.

The type of fire protection provided for each plant area is provided in Table

' 9.5-3 and is discussed in greater detail by fire area and zone in Section 3.0 47 of the FHAR.

Fire Protection System Piping and Instrument Diagrams (P& ids) are provided as Figures 9.5.1-51 through 9.5.1-58. 47 9.5.1.2.1 Fire Protection Water Supply System: Plant fire protection '

systems which utilize water are supplied by an underground piping ring main l 47 system. This undergroung ing main is installed in accordance with the requirements of NFPA 240 he system piping is of cement-lined, ductile iron with push-on joints, and the thrust forces are restrained by tie-rods and l 47 clamps. The entire underground piping system is cathodically protected.

l The STP plant layout comprises two units, approximately 600 ft apart. The underground ring main encompasses both units, and a cross-connection routed between the units connects the north and south sides of the ring to form a figure-eight configuration. The piping used in the primary ring main is of 14-in. nominal size, and can supply the largest water demand of any hasard if 47 that part of the main which would have normally provided the shortest path to the hazard area is out of service.

Sectional isolation valves of the post indicator type are installed in the

[ ' ring main to permit the isolation of any part of the main without removing coverage from any area of the plant. g 9.5-3 Amendment 47

indicator valves are installed in all such branches as they leave the main, to )

parait the isolation of any system.

In addition to supplying the building internal and special equipment protec-j tion systems, the ring main also provides water for the Yard Fire Protection

] System. This system comprises fire hydrants strategically located at approxi-

{ mately 250-ft intervals to provide a good fire-fighting capability. Special l47 attention is given to the placement of hydrants in the vicinity of fire j) hrzards such as the turbine lube oil area, oil-filled transformers, auxiliary i boilers, fuel oil storage area, etc. Each fire hydrant is contained in a hose house which, as a minimum, is equipped with hoses and nossles as required by kNFPA24f9tydrantsaretwo-wayandarefittedwithhosevalves. Threads on hydrant hose valves and hose equipment are National Hose Thread. This hose 47 thread is also used by fire departments and brigades in the vicinity of the

! oite.

Three UL-listed fire water pumps, installed in three separate cubicles within a fire pump hours, are used to provide the required water pressure and flow in the system. Prior to fire water pump start, required water pressure is main- 13 i tcined by an electric jockey pump.

l Each pump is complete with a diesel-engine driver, a fire pump controller, dual starting batteries, and a 550-gallon diesel fuel oil storage tank. The

] three pumps complete with the above accessories, are separated by 3-hour rated i fire barriers and the entire building is provided with a wet pipe sprinkler

Two 14-in.-diameter pipe connections are provided between each storage tank and the 16-in.- diameter header (total i four 14-in.-diameter pipes). Isolating valves are provided at the suction j nozzles of the tanks and in each of the 14- in.-diameter pipes as they join i the header. Similar valves are provided in the 16-in. header and in each of j the three 14-in.-diameter pump suction lines as they leave the header. Thus, ,

, any pump or combination of pumps can take suction from either or both fire '

, through the interconnecting piping. Both tanks are used only for fire water ctorage, and no outlets are provided for connection to any other system. ,

9.5.1.2.12 Turbine Lube 011 Area: The turbine lube oil area comprises a l47 lube oil reservoir, clean and dirty oil storage tanks, and a lube oil condi-tioner located outdoors and adjacent to the southwest corner of the TCB. The lube oil reservoir is a horizontally positioned cylindrical steel tank, 114 in. in diameter by 432 in. in length, located on a curbed concrete slab at El. 44.0 ft. The clean and dirty oil tanks are cylindrical steel tanks, of 23,000 gallons each, located at El 21.5 ft below the reservoir. Two-hour fire-rated walls are provided for the TGB adjacent to the lube oil area for exposure protection.

The lube oil area is protected by two independent water spray fixed systems:  !

one for the reservoir at El. 44.0 ft and one for the tanks and conditioner below. These systems utilize solid cone directional spray nozzles to provide essentially complete direct impingement onto exposed surfaces of the equip-ment, including floor areas within the curbs.

The panel also activates a fire alarm bell local to the protected area. A visible indication-is provided on the panel to show which system is indicating a fire alarm. The HVAC carbon fil- l55

The operability of fire protection systems required to protect safe shutdown capability will be assured through the implementation of an administrative

, program similar to the requirements of Revisien 5 of NUREG-0452. This program 4

will include testing requirements, compensatory actions for systems out of 58

service, and QA audits of program implementation. It will cover those systems, including suppression systems, detection systems, and fire barriers, which are identified in the Fire Hazards Analysis Report as protecting areas / zones containing safe shutdown equipment or cabling.

I Other fire protection systems and equipment will not be included in the administrative or QA programs described above; however, operability testing of

.i a similar nature will be conducted as necessary for property protection and J personnel safety reasons. The need for compensatory actions will be evaluated

on a case by case basis.

9.5.1.6.2_ Fire Brigade: A five member fire brigade consisting of the l Chemical Operations Foreman (Brigade Leader) and four other members of the - MO.

Chemical Operations shift crew will be maintained'on each shift. These  ;

4 employees will receive annual physical examinations for strenuous activity and J

will be given training on safety-related systems and other systems as neces-j sary.

Fire brigade members will be provided with protective equipment as described

, below: -

1. Turnout gear including bunker coat, boots, gloves, helmet, and self con-l tained breathing apparatus (SCBA). At least 10 SCBAs with full-face 1 positive-pressure masks will be available for fire brigade personnel.

l 2. Portable lights.

3. Communications equipment.

4. Ventilation equipment.

5. Portable extinguishers.

, At least one hour of extra air in bottles will be available onsite for each of j the ten SCBAs. In addition, a sufficient supply of air will be maintained onsite to supply the five man fire brigade for six hours, g

( The fire brigade training program will include initial training, periodic 4 retraining, and fireground practice sessions. Additional information con- .

cerning fire protection training including fire brigade training, general l employee training, training for offsite fire departments, and contractor / tem. .

i porary employee training is provided in Section 13.2.3. )

f Each shift fire brigade will conduct planned quarterly meetings to review changes in the fire protection program, plant modifications, changes in fire preplans, and other related subjects of interest.

I Drills will be conducted quarterly for each shift fire brigade. Watch station

, assignments will be considered in planning drills i an effort to ensure that j ( each fire brigade member participates in at least7 drillfperyear. Addi. l l tional information concerning frequency, purpose, and content of drills is j i provided in Section 13.2.3. i j 9.5 28 Amendment 58 l
