FIRE PROTECTION SYSTEMS q The OPERABILITY of the fire protection systems ensures that adequate fire protection features are available to detect, confine, and extinguish fires occurring in any portion of the facility where safety-related equipment is q located. The fire protection system consists of fire detection i instrumentation, fire pumps, and water distribution mains, spray and/or l sprinkler systems, CO2 systems, fire hose stations, yard fire hydrants and I hose house stations and fire barriers. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

OPERABILITY of the detection instrumentation ensures that both adequate warning capability is available for prompt detection of fires and that fire suppression systems that are actuated by fire detectors will discharge extinguishing agent in a timely manner. Prompt detection and suppression of fires will reduce the potential for damage to safety-related equipment an integral element in the overall facility fire protection program.

In the event that portions of the fire protection systema are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service.

When the inoperable fire fighting equipment is intended for use as a hackup means of fire suppression, a longer period of time is alleaed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

If in the event that all the high-pressure fire purps become inoperable, an alternate backup pump or supply is available, such as using the additional fire Iamp which normally protects outlying areas cnd mobile fire armaratus to maintain the 2500 gpm water supply capacity.

Fire protection water systems protecting areas containing redundant safe shutdown systems, as defined in BFN's Fire Hazard Analysis, warrant more stringent compensatory measures (i.e., continuous fire watches) than areas

~

containing only one division of safe shutdown systems or cafety-related equipment not required for safe shutdown under fire conditions.

, The surveillance requirements provide assurances that the minimum OPERABILITY requirements of the fire protection systems are met. All fire protection equipment surveillances required by this technical specification can be performed when the unit is in any operating mode.

BFN Unit 1 3.11/4.11-23

3.11 BASES (Cont'd)

FIRE PROTECTION SYSTEILS. O ont'd)

Flushing of the high-pressure fire protection system mains and building headers assures that sediment and marine growth is removed from the system to prevent obstruction. Subsequent biocide addition reduces further marine organism growth. Individual hose stations and fire hydrants are not included in the overall flush requirements, but are flushed periodically during specific operability verifications. Hydraulic performance of the water fire suppression system is tested in accordance with the 16th Edition of the Fire Protection Handbook, published by the National Fire Protection Association.

The functional integrity of the fire barrier assemblies and penetration sealing devices ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility. This design feature ninimizes the possibility of a single fire from involving several areas of'the facility prior to detection and extinguishment. The fire barrier penetrations are a passive element in the facility fire protection program and are subject to periodic inspections. .

The barrier penetrations, including fire doors, fire dampers, and cable and pipe penetration seals, are considered functional when the visually observed condition indicates no significant degradation.

3.11 BASES FIRE PROTECTION SYSTEMS The OPERABILITY of the fire protection systems ensures that adequate fire protection features are available to detect, confine, and extinguish fires cccurring in any portion of the facility where safety-related equipment is located. The fire protection system consists of fire detection instrumentation, fire pumps, and water distribution mains, spray and/or i sprinkler systems, CO2 systems, fire hose stations, yard fire hydrants and hose house stations and fire barriers. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

OPERABILITY of the detection instrumentation ensures th.t both adequate warning capability is available for prompt detection of fires and that fire suppression systems that are actuated by fire detectors will discharge extinguishing agent in a timely manner. Prompt detection and suppression of fires will reduce the potential for damage to safety-related equipment and 'is an integral element in the overall facility fire protection program.

In the event that portions of the fire protection systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the inoperable equipment is restcred to service.

When the inoperable fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

If in the event that all the high-pressure fire pumps become inoperarle, an alternate backup pump or supply is available, such as using the 6dditional fire pump which norma'.!y protects outlying areas and mobile fire apparatus to maintain the 2500 gpm water supply capacity.

Fire protection Vater systers protecting areas containing redundant safe I shutdown afstems, as defined ir. BFN's Fire Hazard Analysis, 9 arrant more stringent compensatory measures (i.e., continuous fire watchte) than areas containirig only one division of safe shutdown systems or saiety-relatcd equipment not required for safe shutdown under fire conditions.

The surveillance requirements provide assurances that the minimum OPERABILITY l requirements of the fire protection systems are met. All fire protection l equipment surveillances required by thia technical specification can be performed when the unit is in any operating mode, l

FIRE PROTECTION SYSTEMS (Cont'd)

Flushing of the high-pressure fire protection system mains and building headers assures that sediment and marine growth is removed from the system to prevent obstruction. Subsequent biocide addition reduces further marine organism growth. Individual hose stations and fire hydrants are not included in the overall flush requirements, but are flushed periodically during specific operability verifications. Hydraulic performance of the water fire suppression system is tested in accordance with the 16th Edition of the Fire Protection Handbook, published by the National Fire Protection Association.

The functional integrity of the fire barrier ass.emblies and penetration sealing devices ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility. This design feature minimizes the possibility of a single fire from involving several areas of the facility prior to detection and extinguishment. The fire barrier penetrations are a passive element in the facility fire protection program and are subject to periodic inspections.

The barrier penetrations, including fire doors, fire dampers, and cable and pipe penetration seals, are considered functional when the visually observed condition indicates no significant degradation.

3.11 BASES FIRE PROTECTION SYSTEMS  !

The OPERABILITY of the fire protection systems ensures that adequate fire h protection features are available to detect, confine, and extinguish fires cecurring in any portion of the facility where safety-related equipment is located. The fire protection system consists of fire detection instrumentation, fire pumps, and water distribution mains, spray and/or sprinkler systems, C03 systems, fire hose stations, yard fire hydrants and hose house stations and fire barriers. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

OPERABILITY of the detection instrumentation ensures that both adequate warning capability is available for prompt detection of fires and that fire suppression systems that are actuated by fire detectors will discharge extinguishing agent in a timely manner. Prompt detection and supp.9ssion of fires will reduce the potential for damage to safety-related equipment and is an integral element in the overall facility fire protection program.

In the event that portions of the fire protection systems are inoperable, citernate backup fire fighting equipmen*, is required to bs made available in the affected areas until the inoperable equipment is restored to service.

When the inoperable fire fighting equipment is intended for use as a backup teans of fire suppression, a longer period of time is allowed to provide an citernate means of fire fighting than if the inoperable equipment is the Primary means of fire suppression.

If in the event that all the high-pressure fire pumps become inoperable, an citernate backup pump or supply is available, such as using the additional fire pump which normally protects outlying areas and mobile fire apparatus to taintain the 2500 spm water supply capacity.

Fire protection water systems protecting areas containing redundant safe <

shutdown systems, as defined in BFN's Fire Hazard Analysis, warrant more stringent compensatory measures (i.e. , continuous fire watches) than areas ,

containing only one division of safe shutdown systems or safety-related equipment not required for safe shutdown under firc conditions.

The surveillance requirements provide assurances that the minimum OPERABILITY requirements of the fire protection systems are met. All fire protection equipment surveillances required by this technical specification can be performed when the unit is in any operating mode.

FIRE. PROTECTION SYSTEMS (Cont'd)

Flushing of the high-pressure fire protection system mains and building headers. assures that sediment and marine growth is removed from the system to prevent obstruction. Subsequent biocide addition reduces further marine organism growth. Individual hose stations and fire hydrants are not included .

in the overall flush requirements, but are fivshed periodically during i

specific operability verifications. Hydraulic performance of the water fire suppression system is tested in accordance with the 16th Edition of the Fire .

Protection Handbook, published by the National Fire Protection Association.

The functional integrity of the fire barrier assemblies and penetration sealing devices ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility. This design feature ainimizes the possibility of a single fire from . involving several areas of the facility prior to detection and extinguishment. The fire barrier penetrations i are a passive element in the facility fire protection program and are subject to periodic inspections. -

The barrier penetrations, including fire doors, fire dampers, and cable and pipe penetration seals, are considered functional when the visually observed condition indicates no significant degradation. '

ENCLOSURE 2 DESCRIPTION AND JUSTIFICATION BROWNS FERRY NUCLEAR PLANT (BFN)

UNITS 1, 2, and 3 Descriotion of Channe BFN Units 1, 2, and 3 Technical Specifications are being revised to delete ambiguities and to clarify fire protection system Limiting Conditions for Operation (LCO) and Surveillance Requirements (SR). The General Electric (GE)

Standard Technical Specifications (STS), NRC Regulations, and the National Fire Protection Association (NFPA) codes were used to provide guidance for these changes.

Table 1 lists the current BFN technical specification LCO number and the new applicable LCO number. Many of the changes listed in this table do not chanta the intent of the current technical specifications; however, the wording has been changed to be more consistent with current industry practices and standards. Those LCO's that require a change in current BFN practices are discussed in detail in the justification section.

The following LCO's have been added to improve and clarify system operability requirements. These changes will enhance the current technical specifications by providing more meaningful LCO's and clearer guidance for BFN personnel,

a. The Fire Protection Spray and/or Sprinkler System LCO (3.11.C) is being added to identify which spray / sprinkler system is required to be operable, its location, and what actions are needed to be taken if one of the subject systems become inoperable,
b. The Fire Protection Yard Hydrants and Hose House LCO (3.11.F) is being added to identify which hydrants and hose houses are required to be operable, their specific locations, and what actions are to be taken if
  • one or more of the hydrants and houses become inoperable.
c. The Fire Protection Fire Hose Stations LCO (3.11.E) is being added to identify which hose stations are required to be operable, their location, when they are required to be operable, and what actions to take in the event one or more hose stations become inoperable. s Table 2 lists the existing BFN Fire Protection SRs and the new SRs. Many of the changes consist of making the SR periodicity and surveillance wording consistent with the current industry standard 9 and practices. These changes will allow some relaxation in the frequency of testing the fire protection equipment while still verifying system operability.

.e

I The following SRs are being added to provide clearer and better defined SRs to verify system operability:

a. The Fire Pumps and Water Distribution Mains SRs (4.11.B) for the diesel i fire pump are being added to ensure that the diesel fuel tank is  !

maintained at a specific level and the fuel oil is tested in accordance i' with industry accepted standards. In addition, the added SRs ensure that an inspection of the pump is performed as recommended by the manufacturer. SRs demonstrating diesel battery operability are also being added. This will further ensure that the diesel fire pump will perform its intended function wh3n called upon,

b. The SRs being added for the Spray snd Sprinkler System (LCO 4.11.C) are to demonstrate that the valves in the flow path are operable and ensure system integrity is maintained. This SR also verifies that the open
  • nozzles in this system are verified to be free of any blockage.
c. The Fire Hose Station SRs (4.11.E.1).are being added to ensure that the required equipment to maintain the system is operable and the hoses are maintained in an operable condition by performing any needed maintenance such as replacing any degraded gaskets and performing hydrostatic tests.
d. The Yard Fire Hydrants and Hose House SRs (4.11.F) are being added to verify that the required equipment is in the hose house, to ensure that the hydrants are not damaged, and that a hydrant flow test is performed.

This SR also ensures that a hydrostatic test is performed on the fire hoses to ensure their integrity.

e. The Fire-Rated Assemblies SRs (4.11.G.2) are being added to verify the ophrability of the fire doors and their release mechanisms and to ensure that the doors are in their correct position in order to perform their -

intended function.

As a result of this proposed technical specification change, the basis section has also been enhanced to provide additional information to better explain the BFH fire protection system.

Justification Editorial change which does not change the intent of the specification and has no impact on safety.

3. Existinz LCO 3.11.A.1.a Two (2) high-pressure fire pumps OPERABLE and aligned to the high pressure fire header.

New LCO 3.11.B.1.a Two high-pressure fire pumps, one electric and one diesel, each with a capacity of 2500 gpm, with their discharge aligned to the fire suppression header.

Justification This change more accurately reflects the design requirement for the fire protection water supply system as specified by NUREG-0800. The three electric fire pumps are installed in the intake pump house. The power supplies are routed through a cor. mon area (cable tunnel between the turbine building and intake pump station). Thus a e single fire could render all three electric fire pumps inoperable. The diesel-driven ,

fire pump and power supply are remotely located from the intake pump house. The '

diesel fire pump also is provided with a separate feed to the underground fire main.

Thus the requirement for two remotely located pumps enhances the reliability of the high-pressure fire protection water supply

. system. In addition, new SR 4.11.B.1.f verifies at least once per 18 months that all ,

the High-Pressure Fire Protection Water System pumps develop a 2500 gpm flow at the designated system head.

NEW LCO Delete Existing Item Justification Adequate backup fire pump capability is provided as discussed in the justification for new LCO 3.11.B.2, (see below); therefore, a fire watch is not necessary to assure the continued availability of the high-pressure fire water supply system and is being deleted.

, 9-Justification for Channe (Cont'd) l Justification The design criteria for water-based fire suppression systems is such that one fire pump is capable of supplying the largest demand sprinkler system in a safety-related area. Since any one fire pump is capable to meet the fire protection demand, having just one fire pump available for 7 days is adequate. In addition to the four stationary fire pumps (l. Diesel and 3 Electric) which supply fire fighting water, there are other backup pumps available. There are two fire engines on site which have a combined pumping capacity of 1750 gpm. These two mobile pumpors are capable of drafting water from the river and supplying water to the underground fire main through existing fire hydrants. This operation could be completed quickly since there are full time fire fighters at the site. There is also one other 1500 gpm diesel-driven fire pump available that supplies fire protection water to areas outside of the protected plant areas. The outside plant water supply can be pumped into the inside plant water supply through existing fire hydrants and hoses. This would be used as a last resort as the outside plant fire pumps are supplied from a potable water source rather than river water. Therefore, backup provisions are available to ensure that there is an adequate fire protection watec supply for the largest demand suppression system in a safety-related

. area.

Justification for Channe (Cont'd)

Justification There are two backup water supplies available should all four of the plant fire pumps become inoperable. There are two fire engines on site which have a combined pumpiv; capacity of 1750 gpm. These two mobile punpers are capable of drafting water from the tiver and supplying water to the underground fire main through existing fire hydrants. This operation could be completed quickly since there are full time fire fighters at the site. There is also one other 1500 gpm diesel-driven fire pump available that supplies fire protection water to areas outside of the protected plant areas. The outside plant water supply can be pumped into the inside plant water supply through existing fire hydrants and hoses.

This would be used as a last resort as the outside plant fire pump is supplied from a potable water source rather than river water.

Therefore, backup provisions are available to ensure that there is an adequate fire protection water supply for the largest demand suppression system in a safety-related area.

8. Existina LC0 3.11.A.5 Removal of any component in the High Pressure

New LCO Delete Existing Item l

Justification The High-Pressure Fire Protection System shall be operable at all times. However, there are certain allowances for portions of the fire protection systems to become inoperable for i

certain activities such as testing, emergency I operations, maintenance, and modifications. As a

  • l result of com.mitments made in the fire recovery plan (1975), the Plant Manager's approval was 1

Justification for Change (Cont'd) required to take these systems out of service for maintenance and modifications. The operations fire protection staff, as well as the site fire brigade, are notified when any of the systems are taken out of service. The current administrative controls are adequate to ensurc that proper compensatory measures are established.

Therefore, deletion of this technical specification requirement will not affect the overall safety of the plant.

Justification The High-Pressure Fire Protection System consists of several subsystems. The first subsystem is the fire pumps. There are three electric-motor-driven fire pumps and one diesel-driven fire pump. Each of these pumps are rated at 2500 gpm at 300 feet head (electric) or 340 feet head (diesel). SR 4.11.B.1.f uses these values to verify these pumps to be operable. Any

_ one of these pumps are capable of supplying the largest demand suppression system in a safety-related area. The second subsystem of the High-Pressure Fire Protection System is the distribution piping and sectionalizing control or isolation valves. The distribution piping delivers water from the pumps to the various automatic and manual fire suppression systems.

The use of the valves allows sections of the High-Pressure Fire Protection System to be isolated for maintenance with a minimal ,

disruption to the entire system. This proposed technical specification change more adequately l describcs the overall fire protection water -

Justification for Chanze (Cont'd)

Juj_tification The minimum storage tank volumes which have not changed are located in the new SR 4.11.D.1.a.

The justification for removing item 3.11.B.1.c is that automatic initiation logie needs to be operable in order to comply with the intent of the definition of operability as defined in section 1.0.E of the BFN Technical Specifications. This does not change the scope or intent of the present technical specifications.

14. Existinz LCO 3.11.B.2 If Specifications 3.11.B.1.a, 3.11.B.1.b or 3.11.b.1.c cannot be met, a patrolling fire watch with portable fire equipment shall be established to ensure that each area where protection is lost is checked hourly.

Justification for Channe (Cont'd) u Justification Automatic or manual fixed CO2 systems are provided in several areas in the plant. These systems are the primary method of fire suppression in the respective areas except for the cable spreading rooms. The manual CO2 systems in the cable spreading rooms provide back-up to the preaction sprinkler systems. All of the other CO2 system protected areas have backup suppression capabilities in the form of manual fire hose stations. In addition to the manual backup suppression, an hourly fire vqtch must be established upon any of the CO2 syst6ms becoming inoperable (new LCO 3.11.D.2). With the combination of manual backup suppression capability, highly trained fire brigade, and an hourly fire watch, the requirement to go to cold shutdown af ter 7 days is excessive and unnecessary.

16. Existine LCO 3.11.B.4 If CO2 fire protection is lost to a cable spreading room or to any diesel generator building area a continuous fire watch shall be established immediately and shall be continued -

until CO2 fire protection is restored. . . .

New LCO Delete Existing Item ,

Justification As indicated in Section 3.11.D.2, an hourly fire watch is initiated if the CO2 systems become inoperable. The cable spreading room CO2 nystems serve as a manual backup to the preaction ,

sprinkler systems. In addition, manual hose stations are located outside of the cable l spreading rooms to provide an additional leve) of l backup suppression capability. Since the CO 2 l systems in the cable spreading rooms serve only l as a backup, the requirement for a continuous fire watch upon loss wit's the CO2 18 l unnecessary. The eight diesel generator cells l and fuel transfer pump rooms are protacted by an automatic CO2 systems. Manual suppression in l

Justification for Channe (Cont'd) the form of hose stations in the diesel generator (DG) building and yard hose houses with fire hydrants located immediately outside are provided. The DG buildings are also easily accessible to the site fire engine. From the standpoint of safe shutdown, the diesel generators can be crosstied between units 1 and 2 and 3. This will allow the use of either the unit 1 and 2 diesels or the units 3 diesel.

Therefore, with the multiple manual backup suppression and the ability of the plant to, safely shutdown without all of the diesel generators being available, the need for a continuous fire watch in the DG Buildings upon inoperability of the CO2 system is unnecessary. LCO 3.11.D.2 still requires a hourly fire watch to be established if a CO2 system in LCO 3.ll.D.1 becomes inoperable.

Justification The fire protection program at Brown's Ferry is consistent with the NRC's defense in-depth philosophy. The first objective of the defense in depth policy is to prevent fires from occurring. This is accomplished through a set of administrative controls to control combustibles and ignition sources in the plant.

Administrative control procedures have been established to meet this objective. One of these procedures pertains directly to welding, open flame and burning operations in the plant. The procedure conforms to the guidance as outlined in NFPA 51B "Standard for Fire Prevention in Use of Cutting and Welding Processses." As stipulated in the NFPA standard, a continuous fire watch is instituted for all hot work activities except in the maintenance shops. The fire watch is also required to remain in the hot work activity area for 30 minutes after the work is completed to ensure no smoldering fires occur. Since the requirements for fire watches relative to hot work activities are established through administrative procedure, the need to cover fire watch activities in the technical specifications are redundant and unnecessary.

and 4.11.B.1.f(3) Verifying the diesel high-pressure fire pump develops at least 2500 gpm at a system head of 340 feet.

Justifica' tion The existing technical specification (SR 4.ll.A.1.D) currently checks the fire pump capability to be 2664 gpm at 250 feet head. This was based on sprinkler system design criteria established in part X of the BFN Fire Recovery Plan (1975), This original design criteria utilized a design density of 0.3 gpm per ft.2 over 5000 square feet of floor area. However, as a result of BFN's fire hazard analysis, the sprinkler density criteria for the plant sprinkler systems was changed to 0.16 gpm per ft.2 over 1500 square feet. This changed sprinkler density is based on an Ordinary Hazard Group I Classification as defined in NFPA-13.

With the reduction in density, the largest demand sprinkler system flow is less than 2500 gpm

, including hose streams. In addition, NFPA 20 "Standard for the Installation of Centrifugal Fire Pumps" specifies that the fire pumps should be tested to their rated flow capacity and pressure. The increased testing frequency to once every 18 months (new technical specification 4.11.3.1) will provide more reliable and up to date pump capacity data. The increased frequency of pump starts will not be detrimental to their operability.

The cable spreading room systems serve as a backup to the preaction sprinkler systems. Fire hose stations provide backup fire suppression capability to the auxiliary instrument and computer rooms. Upon actuation of a CO2 system, several auxiliary functions occur bbfore the agent is released into the room. These auxiliary functions include the closing of fire doors and dampers.

Justification for Change (Cont'd)

Justification The CO2 tank for units 1 and 2 has a 17 ton '

capacity while the unit 3 tank has a 6 ton capacity. In addition to supplying CO2 for the fire suppression systems, the CO2 tanks are utilized for purging the main generator. The CO2 tanks have therefore been sized to meet both demands. The technical specification operable limits on the CO2 tanks are 50 percent full. The tanks are refilled after each use to ensure that there are adequate supplies of CO2 . A major leak in the system would easily be detected during tours by the plant operators.

The NFPA Standard on CO2 systems (NFPA 12) recommends a weekly check of low pressure CO2 storage tanks for proper agent level. Therefore, the decrease in surveillance frequency of the liquid level of the CO2 tanks from daily to once a week will not decrease any margin of safety or dependability of the system.

Justification Existing SR 4.11.C.2 in addition to existing SR 4.11.C.4 become new SR 4.11.A.3. This is a SR number change in addition to clarifying which circuits are required to be tested. This change does not change the intent of the existing SRs.

50. Existina SR 4.11.C.3 The class A supervised detector alarm circuits will be tested once each two months at the local panels.

New SR 4.11.A.2 The supervised circuits associated with alarms of each of the above required fire detection instruments shall be demonstrated OPERABLE at least semiannually.

J'ustification The fire detection system consists of smoke and heat detectors, local panels, and alarms.

Portions of the fire detection circuitry are supervised so that a open or grounded cable will cause a trouble alarm. Should an open, resulting in a fire alarm, or ground condition occur on any portion of the supervised circuit, the system will still be able to annunciate a fire alarm to the local panel. With the capabilities of the supervised circuits as outlined above, the decrease in testing frequency from two months to six months will not be adverse to the safety of the plant. The six-month testing meets the intent of NFPA 72D requirements.

a NOTE: The nonsupervised circuits continue to be tested monthly.

51. Existing SR 4.11.C.4 The circuits between the local panels in 4.11.C.3 and the main control room will be tested monthly.

New SR 4.11.A.3 The nonsupervised circuits associated with alarms of each of the above required instrument shall be demonstrated OPERABLE at least monthly.

Justification Same justification as in existing SR 4.11.C.2 and new SR 4.11.A.3.

52. Existina SR 4.11.C.5 Smoke detector sensitivity will be checked in accordance with manufacturer's instruction annually.

New SR Deleted Justification This SR checks the sensitivity of each of the individual smoke detectors in accordance with manufacturer's instructions. The sensitivity of the detectors is initially set at the factory by the manufacturer. Sensitivity testing as specified in NFPA 72E-1984, "Standard on

. Automatic Fire Detectors," requires that the sensitivity be checked one year after installation and every other year thereafter.

However, the sensitivity test does not specifically test the detectors for operability.

New SR 4.11.A.1 is the six-month channel functional check which ensures operability of the detectors. Therefore, the intent of the technical specification requirement is satisfied by the six-month functional check. A surveillance instruction for each reactor unit currently exists to test detector sensitivity; in the event of a detector being out of tolerance, it will be adjusted or replaced.

These procedures will become part of the plant fire protection program once sensitivity testing is removed from the technical specifications.

53. Existing SR 4.11.D Roving Fire Watch - Deleted New SR None Justification Previously deleted and approved by NRC.
54. Existing SR 4.11.E Each required fire barrier penetration shall be verified to be functional at least_once per 18 months by a visual inspection, and prior to restoring a fire barrier to functional status following repairs or maintenance by performance of a visual inspection of the affected fire barrier penetration.

New SR 4.ll.G Each of the required fire-rated assemblies and penetration sealing devices shall be verified OPERABLE at least once per 18 months by performing a visual inspection of:

The exposed surfaces of each fire-rated assembly.

Each fire damper and associated hardware.

At least 10 percent of each type of sealed penetration. If changes in appearance or abnormal degrada' ions are found, a visual inspection of an additional 10 percent of each type of sealed penetration shall be made. This inspection process shall be continued until a 10 percent sample with no apparent changes in appearance or abnormal degradation is found.

Samples shall be selected such that each penetration seal will be inspected at least once per 15 years.

Each of the required fire doors shall be verified

' OPERABLE by inspecting the automatic hold-open, release, closing mechanisms, and latches at least semiannually and by verifying:

Justification for Channe (Cont'd)

The OPERABILITY of the fire door supervision system for each electrically supervised fire door by performing a CHANNFL FUNCTIONAL TEST at least monthly.

That each locked-closed fire door is verified closed at least weekly.

That doors with automatic hold-open and release mechanisms are free of obstructions at least daily and perform a functional test of these mechanisms at leant once per 18 months.

That each unlocked normally closed fire door without electrical supervision is verified closed at least daily.

Justification Penetration seals are a passive barrier and are generally not subject to damage. Ten percent of the penetration seals provides an adequate sample to determine whether any generic damage to the seals is occurring. There are provisions for inspecting a larger sample of penetration seals if damage is detected. The revised technical specifications will not be adverse to the safety of the plant.

The repair or modification of fire barrier

. penetration seals is controlled by existing ,

procedures. These procedures ensure that the seals are returned to their original configuration. Therefore, this technical specification requirement will not adversely affect the safety of the plant and is being deleted. "

Fire doors are an integral part of the plant fire barriers. Surveillance requirements for the fire doors will be revised to address the various configurations which exist. For doors which have limited control such as unlocked, nonelectrically supervised doors, the surveillance will be more frequent. The periodicity for surveillances of the various fire door configurations is consistent with industry standarde.

Justification Fire hose stations are located throughout the plant to provide manual fire fighting capability. In some areas of'the plant, the hose stations serve as a backup to the fixed suppression systems. For areas with no fixed suppression systems, the hose stations provide the primary means of fire suppreasion. To ensure that the hose station valves are operable, the valves will be cycled on a periodic basis. The fire hose and gaskets will be inspected and tested to verify they are in working condition.

These new technical specification surveillance and testing requirements will ensure that the plant hose stations are operable.

These hydrants and hose houses provide supplemental manual suppression capabilities for several buildings and provide protection against exposure fires from outside the buildings. To ensure that this equipment is available and operable, new surveillance and testing requirements will be added to the plant technical specifications.

r ENCLOSURE 3 DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION BROWNS FEVRY NUCLEAR PLANT (BFN)

UNITS 1, 2, AND 3 Descrintion of Amendment The proposed amendment would change the technical specifications of BFN units 1, 2, and 3 by revising the limiting conditions for operation and the surveillance requirements for fire protection systems. These changes are proposed in order to eliminate ambiguity and to bring the BFN Technical Specifications into conformance-with the guidelines of the Boiling Water Reactor (BWR) Standard Technical Specifications (STS) and other acceptable industry practices. These changes more clearly define the applicability of the fire protection systems and define the actions and compensatory measures to be taken to ensure the safety of protected equipment.

Basis for ProDosed No Sinnificant Hazards Consideration Determination NRC has provided standards for determining whether a significant hazards consideration exists as stated in 10 CFR 50.92(c). A proposed amendment to an operating license involves no significant hazards considerations if operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from an accident previously evaluated, or (3) involve a significant reduction in a margin of safety.

1. This proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated. The amendment does not modify or introduce any new equipment or systems not previously analyzed by the BFN Final Safety Analysis Report (FSAR) nor do -

these changes delete or degrade any safety-related equipment currently installed at BFN. The BWR STS, NRC regulations, National Fire Protection

Association standards, and vendor recommendations for BFN were used as '

guidance in preparing those proposed amendments. These changes will not change the BFN FSAR accident analysis. The BFN FSAR accident analysis envelopes any accident scenario that could result from the implementation

) of the proposed amendment.

! 2. The proposed amendment does not create the possibility of a new or I

different kind of accident from an accident previously evaluated. This amendment does not introduce any new equipment, modification to existing I

equipment or any adverse conditions to current operating practices. The operating requirements, procedures or modes of system operability are not degraded as a result of these changes. Operating limits are not affected and systems are not challenged in such fashion that a new or different accident scenario would be created.

Basis for Proposed No Sinnificant Ifazards Consideration Determination (Cont'd)

3. The proposed amendment does not significantly reduce the margin of safety. Plant safety is enhanced by providing more detailed and comprehensive curveillance requirements to ensure fire protection systems are capable of performing their intended functions. Additional LCO's are provided to ensure that the required safety-related systems and safe shutdown systems have adequate fire protection. The amendment does not invalidate BFN-FSAR assumptions and analysis and conforms to the intent of the General Electric STS.

l Determination of Basis for Proposed No Sinnificant Hazards l

l l

I Since the application for amendment involves a proposed change that is encompassed by the criteria for which no significant hazards consideration exists, TVA has made a proposed detormination that the application involves no significant hazards consideration.
