Each fire area was investigated for fire loading.

Further delineation of the hazards analysis into fire zones provides a closer estimation of fire loads within the fire area.

The total Btu content of each area or zone is the sum of all combustibles in that zone.

Average Fire Load = Total Btu content Btu Area of Zone (ft

26 The oil day tank rooms have high fire loadings because total f 26 volume burning has been assumed.

This calculation also takes no credit for fixed extinguishing systems provided for all oil hazards.

Also, a free influx of air is assumed.

If the fire barrier remains

intact, a significantly reduced fire exposure can be expected.

Nine Mile Point Unit 2 FSAR The next highest fire loadings are heavy cable tray concentrations in the control building and electrical tunnels.

Calculations for these areas are also conservative.

0 Nine Mile Point Unit 2 FSAR maximum allowable.

In any case, cable tray water sprinkler systems are provided for these areas.

26 The next highest fire loadings are in the radwaste building.

The calculation for this area is also conservative.

In calculating fire loading for the diesel generator room, 'a fuel oil pipe rupture has been assumed with the entire contents of the fuel oil day tank spilled on the floor. It was also considered that all of the lube oil contained in the crankcase of the engine would leak out.

These assumptions resulted in a fire loading of 1 hr 22 min, which is still less than the 3-hr walls that. have been provided.

Automatic pre-action water sprinkler systems have been provided for the diesel generator building.

The normal switchgear building also has a high fir'e loading, but it is less than the 3-hr fire walls that have been provided.

Automatic total-flooding CO> systems have been used in this building and in other switchgear rooms.

Fire loading for all other areas is approximately 2 hr or less.

In spite of the low'fire

loading, 3-hr fire walls have been provided wherever separation is required or desirable.

9A.3.1.2.5 Detailed Fire Hazards Analysis by Building The following sections provide the detailed fire hazards analysis and a summary of the effects of fires in fire zones.

This summary shows that the fire protection system will provide adequate ability to

detect, prevent, and suppress postulated fire outbreaks in and around the plant.

9A.3.1.2.5.1 Standby Gas Treatment Building Introduction The standby gas treatment (SGT) building is ad)acent to the reactor building.

It houses the SGTS

units, reactor building ventilation supply unit, and railroad access

bay, all of which are separated from each other by 3-hr fire walls and floors.

Construction of the SGT building is detailed in Section 3.8.4.1.9.

Safet -Related S stems The SGTS units are the only safety-related equipment in this building.

Nine Mile Point Unit 2 FS 9A.3.5. 1.3 Penetration Openings for Ventilation Systems Openings through fire barriers for ventilation'ystems are'rotected

" by UL-labeled fire dampers with

'a rating equivalent to that required of the barrier.

Flexible air duct coupling in ventilation and filter system is non-e ombus tib le.

9A.3.5.1.4 Door Openings With the exception of special doors such as pressuretight, watertight, radiation shield,

tornado, and railroad

access, the doors installed in the fire-rated assemblies are UL-labeled fire doors.

Table 9A.3-16 lists pressuretight, watertight, radiation shielded,

tornado, and railroad access doors to be install,ed in fire barriers and the corresponding fire loading on either side of each door.

Figures 9A.3-14 through 9A.3-17 show typical sections and details and demonstrate by engineering analysis that the door panels and

hardware, when subjected to heat (up to 2000~F) for 3 hr on one

side, will be free to expand in all directions and maintain the doors in the closed position.

No significant deformation or warping of door panels which could allow fire propagation is excepted.

Table 9A.3-17 provides a

comparison between UL-labeled Class A rated fire doors and Unit 2 nonlabeled doors.

Fire door position will be monitored and verified to be maintained in accordance with BTP CNEB 9.5-1 Section C.S.a(5).

Installation of fire doors is in accordance with NFPA-80 and applicable UL requirements.

9A.3.5.1.5 Personnel Access and Escape Routes Two means of egress are provided from each fire area.

Stairways required for egress are enclosed and ventilated to minimize smoke infiltration and to provide a safe means of egress in the event of a fire.

Exit routes are clearly marked.

The enclosures are designed for a 2-hr fire rating and equipped with UL-listed, self-closing Class B fire doors.

Elevator enclosures and chutes are similarly designed.

9A.3.5.1.6 Sharing of Cable Spreading Rooms Unit 2 does not share a cable spreading room with Unit 1.

Nine Mile Point Unit 2 FSAR Drains are discussed in Section 9A.3.5.1.12.

Smoke removal is provided by normal ventilation and portable smoke removal units.

9A.3.1.2.5.10 Reactor Building Introduction Due to the presence of floor openings, the entire reactor building is considered a

single fire area.

Each floor elevation is considered a separate fire zone and each half of the building is considered as a

fire subarea.

The analysis of the contained hazards indicates that the average fire loading for each zone, with the exception of the HPCS room and 600-V switchgear

room, is less than 1 hr.

A 20-ft-wide zone is provided between the north and south halves on the 0- to 180-deg line.

The 20-ft zone consists of two adjacent. 10-ft zones with detection and automatic suppression systems.

26 To reduce the potential for the vertical spread of fire along cable tray risers, penetration seals are provided for cable tray risers.

Refer to Figures 9A.3-2 through 9A.3-8 for the actual configuration of the fire stops.

Elevation 353 ft 10 in is a nonrated barrier which separates fire subareas FSA 34 and FSA 35.

There is no fire loading or safe shutdown equipment:

located on elevation 353 ft 10 in; therefore, safe shutdown capability is not affected.

The reactor building has a

ventilation system utilizing 100 percent outside air for normal operation.

This system will remove smoke in the 'event of a

fire, as long as radiation levels remain below acceptable levels.

The primary containment is also considered one fire area.

However, due to the low fire

loading, primary containment

inerting, and lack of continuity of combustibles, a fire that would spread from one hazard to another is not postulated.

Safet -Related and Reactor-Associated S stems The following table includes both safety-related and reactor-associated systems and gives their locations in the reactor building.

9A.3.1.3.3 Seismic Design Basis Standpipes and hose connections for manual firefighting are se1sm1cally supported in safety-related areas and in areas containing safety-related equipment.

The design bases do not contemplate simultaneous earthquake and fire conditions; additionally, Unit 2 is not in an area of high seismic activity, therefore these requirements were not incorporated into the design.

9A.3.1.3.4 Design Basis Analysis 26

)

GDC-3 requires that firefighting systems be designed to ensure that rupture or inadvertent operation does not significantly impair the safety capability of structures,

systems, and.

components important to safety.

Redundant trains of components required for safe shutdown that are susceptible to damage from water spray are physically separated so that manual fire suppression activities will not adversely affect the operability of components not involved in the postulated fire.

Where necessary, appropriate protection is provided to prevent impingement of water spray on components required for safe shutdown.

Section 3C.4 provides further details regarding the effects of spraying on safe shutdown components.

Automatic suppression systems have been designed and located so that.

operation of the

systems, either intentionally or inadvertently, will not cause damage to redundant trains of components required for safe shutdown.

26 The fire hazards analysis that is included as part of the FSAR defines the effects of postulated fire outbreaks.

Details for the effects and analyses for wind and tornado loading, water level (flood),

and missile protection are described in Sections 3.3, 3.4, and 3.5.

9A.3.1.3.5 Moderate Energy Line Break Analysis The consequences of a crack in a moderate energy line in the fire suppression system are included in the energy pipe break analysis for Unit 2 (refer to FSAR Section 3.6A).

There are approximately 12 safety-related, motor-operated isolation valves in the reactor building that must be located out of their division.

The analysis of FSAR Appendix 9B shows that Sufficient

~

equipment remains free of damage from a single fire to achieve safe shutdown of the plant.

The Division III pump (HPCS) is located in the south half of the reactor building; however, it is completely isolated by 3-hr rated fire walls.

The Division III cables are provided from a

separate buried duct bank outside the reactor building.

'ith tha fire protection systems out of service, the low fire load, lack of continuity of combustibles, and the 20-ft fire break along the 0- to 180-deg line in the reactor building support the implausibility of fire spreading from the north half to the south half.

With the fire protection systems in service, it is unlikely that the fire would spread beyond the point of origin.

Radioactive Release Anal sis The reactor building ventilation consists of a

normal ventilation system and an emergency recirculation air system.

The normal ventilation exhaust from the reactor building is monitored for radiation by radiation monitors located in the exhaust.

The maximum firefighting water flow for the diesel generator building exceeds the maximum firefighting water flow (and subsequent buildup due to compartment size) for all other safety-related areas.

Based on an evaluation of this water flow and the results of the analysis described in Section,3C.5, Compartment Flooding as a Result of Breaks or Cracks, firefighting water flow and subsequent buildup will be removed by floor drains and not cause the loss of redundant trains of equipment required for safe shutdown for all other safety-related areas.

In areas containing combustible liquid storage and piping, traps are provided in the floor drains and curbs.

9A.3.1.2.2 Organization of Fire Hazards Analysis In order to develop data meaningful to the analysis, the plant has been divided into numerous fire areas, and these areas are further subdivided into fire zones.

The fire areas and zones are shown on Figures 9A.3-1 through 9A.3-8, 9A.3-12, and 9A.3-13.

Fire areas are those areas separated from adjacent areas by rated fire barriers.

A comparison between Unit 2 fire barr'iers and tested fire barriers is provided in Section 9A.3.5.1.1.

Calculation of fire loading for each fire zone is included in Tables 9A.3-1 through 9A.3-11.

The basis of calculation is shown below.

9A.3.1.2.3 Basis of Calculation In Tables 9A.3-1 through 9A.3-11, all known combustibles are identified for each fire zone.

The calorific content of the combustibles and the Btu/sq ft loading for each fire area have been calculated.

In order to

'determine the fire

loading, it was necessary to make some assumptions concerning the amount of combustibles in such equipment as motors and control cabinets.

The following assumptions, which are based on engineering

judgment, were utilized to estimate the weight. of combustibles:

Nine Mile Point Unit 2 FSAR Construction of the diesel generator building is discussed in Section 3.8.4.1.3.

Safet -Related S stems The diesel generator building contains the Division I and II and HPCS (Division III) diesel generators.

These three generators provide power to essential equipment if both normal and preferred station service power are lost.

Post Fire Anal sis The fire loading for the diesel generator room in the diesel generator building is 2 hr 24 min.

This is based on a

postulated fuel oil line rupture and the spilling of the entire contents of the fuel oil day tank into the diesel generator room.

Fire wall separation of diesel generators and fuel oil day tanks precludes a fire in one section from disabling other systems.

Therefore, safe shutdown capability is assured.

If fire protection systems were in service, a fire would be extinguished.

Radioactive Release Anal sis There is no source of radioactivity in this building.

Fire Detection and Su ression All diesel generators are protected with preaction sprinkler systems.

The deluge valves for these systems open automatically on a

signal from photoelectric detectors in the respective diesel generator rooms.

Division I and II diesel generators as well as the HPCS (Division III) diesel generator have been modified to allow water spray without damaging the engine or generator.

) 26 26 The backup systems for the diesel generators are manual water and CO+ hose reels and portable extinguishers.

C The diesel generator day tank room has a fire loading of 6 hr 54 min.

Raised thresholds are provided so that the entire contents of the tank would be contained in the event of a tank rupture.

As was discussed previously, if the entire contents of the fuel oil day tank were spilled in the diesel generator room, the fire loading would be 2 hr 24 min and a

fire would be contained within that area.

fans, isolation

dampers, and controls dedicated to smoke removal.

Portions of the normal ventilation system components are used in certain areas for smoke removal.

Fire dampers are provided where ventilation ductwork penetrates fire barriers.

For large (high-heat) fires, the fire dampers would close.

These dampers can be manually reopened by plant personnel for smoke removal.

Location and operation of smoke removal dampers will be shown on individual preplan procedures for each area of the plant.

Monitors are provided in the reactor

9A.3.6.2.8 Reliable Water Supplies The source of water supply to the fire pumps is Lake Ontario.

Each pump takes suction from the seismically designed service water intake tunnel.

Nine Mile Point Unit 1 fire pumps (rated at 2,500 gpm at net discharge pressure of 125 psig) also take suction from Lake Ontario through a separate and remote intake tunnel.

The fire main loops for Nine Mile Point Units 1 and 2 are interconnected in two places with normally closed

valves, one remotely operable from the Unit 1 control room.

9A.3.6.2.9 Fire Water Supply The fire water supply (Lake Ontario) is a fresh water supply and is essentially unlimited.

The flow rate with one pump out of service is a

nominal 2,500 gpm at net discharge pressure of 125 psig; this is ample for the largest deluge system plus 500 gpm for manual hose stream.

The largest design demand would result from the simultaneous operation of the two largest deluge systems (water/foam systems F-1 and F-2) and the turbine generator bearing water spray system (W-25),

which are located in the turbine building.

The design demand for water/foam system F-1 (zone 734 SF) is 1,048

gpm, for water/foam system F-2 (zone 735 SF) is 655

gpm, and for turbine generator bearing water spray system W-25 is 590 gpm.

All design demand pressures are below 100 psi at elevation 261 ft-0 in.

The total flow

rate, including 500 gpm for hose

streams, is 2,800 gpm.

This demand can be met with either fire pump out of service.

This exceeds the demand in any safety-related area.

9A.3.6.2.10 Lakes of Freshwater Ponds See Section 9A.3.6.2.8 concerning two intakes.

The intake tunnel from Lake Ontario also feeds the service water system.

Sufficient water is available for both systems, and a failure of the fire protection system does not affect the service water system.

9A. 3. 6. 3 Water Sprinkler and Hose Standpipe Systems 9A. 3. 6. 3. 1 Automatic Sprinkler System Sprinkler systems and manual hose station standpipes are connected to the underground yard main and arranged so that a single failure will not impair both the automatic fire Amendment 26 9A.3-51 May 1986

Nine Mile Point Unit 2 FSAR protection system and the hose reels that provide backup protection.

Fire mains are provided in the turbine building, control building, and reactor building, which are fed from the yard main at both ends.

This is considered to be an extension of the yard main.

Automatic sprinkler flow alarms are provided.

Nine Mile Point Unit 2 FSAR During normal operation, the opening of one heat vent does not result in a release of radioactivity because the 'exhaust fan maintains the turbine building at a negative pressure.

In the event of a fire with multiple operation of the heat

vents, the design objectives of 10CFR100 would not be exceeded.

Fire Detection and Su ression S stems Each area of the turbine building is protected by a zoned, early warning smoke detection system arranged to alarm locally and in the control room.

Automatic wet-pipe sprinkler systems are provided for protection of general areas at el 250 ft 0 in and 277 ft 6 in.

A system of six automatically operated foam water sprinkler systems (foam injection is manually controlled) covers the area under the turbine generator below el 306 ft 0 in.

These systems would lay a blanket of foam on the floor under the turbine generator at el 277 ft 6 in to cover any accumulation of burning or unburned oil being discharged from a leak on the machine and to flow down the sides of the machine and lay a blanket of foam in the condenser

pit, at el 239 ft 4 in.

The foam water sprinkler systems utilize open foam water sprinkler heads spaced to achieve area

coverage, and the water phase is actuated automatically by heat detectors.

The water supply. to the systems is controlled by automatic flow control valves.

The foam concentrate pump is manually started.

Two equal capacity foam pumps are provided for the foam water sprinkler systems.

One is on automatic standby.

Two foam concentrate tanks are provided for foam water sprinker systems and foam hose reels.

To assist manual firefighting around the turbine generator, the water hose stations in the vicinity of the unit are provided with piped foam concentrate so that either water or foam streams are available at these stations.

COq hose reels are also provided.

Carbon dioxide total-flooding systems are provided for switchgear

rooms, the alternator exciter enclosure, and the lube oil reservoir (manual system for inerting vapor space).

Manual local application CO<

backup to the local application CO< systems.

Water deluge systems are provided for the reactor feed pumps Cable tray water sprinkler systems are provided for turbine building cable trays except those in switchgear rooms and those that are protected by general area sprinkler systems.

The clean and dirty oil storage room and the lube oil reservoir have fire loadings of 16 hr 24 min and 14 hr 42

min, respectively.

(The oil storage rooms have high fire loadings due to the fact that total volume burning has been assumed.

With fire barriers

intact, the influx of combustion air would be restricted, which would limit the amount of oil actually burned.)

The doorways are elevated to contain the oil in the event of a tank rupture.

Because of the high fire loading, sprinkler systems have been provided for these areas.

Backup protection is provided by manual water hose reels and portable extinguishers.

Drains are described in Section 9A.3.5.1.12.

The hotwell pit has ample ponding capability to hold lube oil line break and expected water from firefighting.

9A.3.1.2.5.5 Diesel Generator Building Introduction The diesel generator building is a single-floor, concrete structure.

It contains the two standby diesel generators and the HPCS diesel generator that provide power if both normal and preferred station service power are lost.

Diesel generators are separated from each other by 3-hr fire walls.

Diesel generator day tanks are also located in separate rooms surrounded by 3-hr walls.

Doorways to day tank rooms have raised thresholds sized to contain the entire contents of the tank and water discharged for fire fighting purposes in the event of a

leak and subsequent fire.

A common ventilation exhaust chase is located on elevation 272 ft 0 in of the north end of the building.

Discharge grills from each diesel generator room exhaust into the chase.

Nine Mile Point Unit 2 FSAR Associated Circuits Cables (safety-related, nonsafety-

related, Class lE, and non-Class 1E) that have a

physical separation less than that required by Section IIE.G.2 of Appendix R, and one of the following:

A common power source with the shutdown equipment (redundant or alternative) and the power source is not electrically protected from the circuit of concern by coordinated breakers,

fuses, or similar devices.

2.

A connection to circuits of equipment whose spurious operation would adversely affect the shutdown capability.

3.

A common enclosure with the shutdown cables that is not protected by circuit breakers, fuses or similar

devices, or that will allow propagation of the fire into the common enclosure.

Automatic Self-acting, operating by its own mechanism when actuated by some impersonal influence such as a

change in

current, pressure, temperature, or mechanical configuration.

Combustible Material Material that does not meet the definition of noncombustible.

Control Room Com lex The zone served by the control room emergency ventilation system (see SRP Section 6.4, Habitability Systems)

Ex osure Fire An exposure fire is a fire in a given area that involves either in situ or transient combustibles and is external to any structures,

systems, or components located in or adjacent to that same area.

The effects of such fire (e.g.,

smoke, heat, or ignition) can adversely affect those structures,

systems, or components important to safety.

Thus, a fire involving one train of safe shutdown equipment may constitute an exposure fire for the redundant train located in the same

area, and a

fire involving combustibles other than either redundant train may constitute an exposure fire to both redundant trains located in the same area.

26 Fire Area Areas within the plant that are totally enclosed by 3-hr fire barriers.

Structural steel forming a part or supporting such fire barriers to be protected to provide fire resistance equivalent to that required of the barrier.

Exterior walls, unless shown on FSAR Figures 9A.3-2 through 9A.3-8, are not fire rated.

Amendment 26 9A.2-2 May 1986

I

Nine Mile Point Unit 2 FSAR 9A.3.5.1.8 Roof Construction Metal deck roof construction, where used, is designed as a

. Factory Mutual Class 1 roofing system.

9A.3.5.1.9 Suspended Ceiling Any suspended ceilings in safety-related areas are of noncombustible construction.

Concealed spaces are void of combustibles except for electrical

cable, which is in metallic conduit.

9A.3.5.1.10 Transformers Transformers located within safety-related areas are of the dry type.

9A.3.5.1.11 Oil-Filled Transformers The plant has an open transformer yard, which contains all the oil-filled transformers applicable to BTP CMEB 9.5-1 Section C.5.a(13).

The west wall of the control building is located within 50 ft, has one protected HVAC air intake

opening, and is constructed in excess of the 3-hr fire-resistive requirements.

Protection consists of a

fire damper (located 6 ft, upstream of the opening) and fire barrier wrap for the exposed duct.

Additional unprotected openings exist that are in excess of 50 ft from the transformers.

9A.3.5.1.12 Floor Drains Floor drains are conservatively sized in accordance with the National Plumbing Code.

Floor drains in safety-related and nonsafety-related areas are approximately spaced at one drain per 575 sq ft, each with a capacity of approximately 70 gpm.

Actual drainage capability would depend on drain

spacing, location, and area involved.

Firefighting water flow depends on the type of suppression system

provided, system design

density, and area of involvement.

Unit 2 fixed water suppression systems incorporate the use of closed-heads and closed-water spray nozzles which limit the amount of water discharged to the area of involvement during a fire.

An evaluation to determine the degree of buildup and its effect was conducted for the diesel generator rooms (the most conservative case).

The result showed that with all Amendment 26 9A.3-43 May 1986

Nine Mile Point Unit 2 FSAR constructed of a minimum of 8-in thick reinforced concrete.

Concrete, in addition to its capability to support

'various

loads, also possesses insulating and fire-resistive properties.

Nationally known and recognized Uniform Building Code (1982 edition)

(herein called UBC) lists the required minimum thicknesses of various insulating materials for fire-resistive periods of 1 hr through 4 hr listed in Tables 9A.3-1 through 9A.3-3.

Based on these tables, it can be concluded that all fire barriers provide a

minimum of 3 hr of fire resistance rating as specified for certain plant areas.

The reinforcing steel with a minimum of 1 in of concrete cover also provides 3 hr of fire resistance rating.

American Concrete Institute (ACI) codes and quality assurance requirements of ANSI N45.2.5, as invoked by NRC Regulatory Guides 1.55 and 1.94, respectively, are used in the design, procurement, and construction of these barriers.

Penetration seals are discusseed in Section 9A'.3.5.1.2.

Comparisons are performed for:

1.

Typical floor system versus corresponding UI-rated sections 2..

Typical steel beam versus corresponding UL-rated beam 3.

Typical wall section versus corresponding UL-rated sections The details of UL-rated sections are 'obtained from the Fire Resistance Directory, published by the Underwriters Laboratories, dated January 1983.

Tables 9A.3-12, 9A.3-13, and 9A.3-14 provide the comparison.

Therefore, while fire testing is not done, the required 3-hr fire resistance is provided.

9A.3.5.1.2 Penetration Seals Openings through fire barriers for pipe, conduit, and cable

trays, which separate fire areas, are sealed to provide a

fire rating equal to the rating of the barrier itself.

Openings inside conduits penetrating fire barriers are sealed at the barrier or at the first opening on both sides of the barrier regardless of the conduit size or distance to the first opening.

The seal materials are ASTM E-119 Amendment 23 9A.3-41 December 1985

o.

e Nine Mile Point Unit 2 FSAR ANI/MAERP tested, provide three hour rating, and demonstrate the following:

~

No significant smoke or hot gas preparation 26

~

No large areas of

heat, rise greater than 3254F above ambient on the cold side.

(In most

cases, maximum cold side temperature did not exceed 325 F).

~

No hot spots that could ignite nearby cable on the code side.

~

Capability to withstand the design differential pressure which is not concurrent with fire.

The following materials may be used:

~

Dow Corning'3-6548 silicone RTV foam.

~

Dow Corning 170 products A and B, Elastomer.

4 To facilitate installation, a fire rated damming material is used when required, Installation of the conduit internal seals is performed by ANI-approved installers based on procedures consistent with the tests conducted.

Threaded unused conduits are capped or plugged on both sides of the fire barrier with a 1/8 in vent hole provided on one side.

Cable trays are supported in a manner similar to the UL test.

Unit 2 penetration seal designs are either the same as Unit 1

designs, which were tested and qualified by Underwriters Laboratories for a 3-hr

rating, or are UL-

listed, 3-hr rated penetration seals (such as link-seals).

This is verified in accordance with the quality assurance requirements.

Cable trays are supported in a manner similar to the UL test.

Unit 2 penetration seal designs are either the same as Unit 1 designs, which were tested and qualified by Underwriters Iaboratories for a 3-hr rating, or are UL-
