Docket Number 50-346 License Number NPF-3 Serial Number 1789 Attachment 2 Page 1 LICENSE AMENDMENT NUMBER 18 SER ALTERNATE COMPLIANCE APPROACilES The following discussions are presentet in the order of appearance in the License Amendment Number 18 Nuclear Regulatory Commission (NRC)

Safety Evaluation Report (SER). Table 1. The numbering corresponds to the item numbers from Toledo Edison letter Serial Number 1788, dated March 22, 1990. The Fire Hazards Analysis Report (FHAR) as referenced herein is Revision 12 9hich was provided to the NRC in Toledo Edison letter Serial Number 1854, dated November 8, 1990. The changes made to the filar to incorporate the Fire Protection Program requirements did not affect the analyses made in the alternative approaches discussed below. These alternate methods of compliance have been reviewed favorably by the NRC Region III in Inspection Report 50-346/90007 (DRS), (Toledo Edison letter 1,og Number 1-2345, dated August 22, 1990).

1. The SER required that adoitional hand-held portable fire extinguishers be provided in the No. 3 Hechanical Penetration Room (Room 303). Toledo Edison's alternate approach states that one hand-held dry chemical portable fire extinguisher in Room 303 is sufficient. filar Section 4.6.AU_for Fire Area AB (Room 303) and FHAR Appendix E (Drawing A223') describe the manual suppression capabilities in Room 303 as one dry chemical, portable fire extinguisher and a hose station located in-the room. This FHAR section and associated drav*ag also show additional manual suppression capabilities ava..able from adjacent areas.

Additionally, Toledo Edison has performed a National Fire Protection Association (NFPA) 10. " Standard for Portaolo Fire Extinguishers", review for Room 303. The review considered the size of the room, the type and size of the existing hand-held portable fire extinguisher, the type of combustibles present, and the fire loading 11 the room. 1he review determined that the cucrently installed extinguisher'in this room is: sufficient. Thus, the alternate approach which reflects existing plant configuration, has i been evaluated and it has been cor.cluded that there is no adverse -

impact on the manual suppression espabilities needed in Room 303.

2. The SER required that additional hand-held portchle' fire extinguishers be added in the Maintenance Room;(Room 320). The alternate approach states _that one hand-held dry chemical or carbon-dioxide portable fire extinguisher in Room 320 is sufficient. filar Sectior 4.6.P _ for Fire Area 'P (Room .320) and Fi!AR Appendix E (Drawing A223F) show the manual suppression capabilities in Room 320 as one carbon dioxide portable extinguisher in'the room'and one dry chemical, portable fire extinguisher'Just outside the. room and a hose line from an adjacent hose station.- This FHAR section and associated drawing also show additional manual suppresslun capabilities available from adjacent areas. Additionally, a NFPA 10 Standard review was nerformed for Room 320.- The review

. considered the size of the room, the type and size of the existing hand-held portable fire extinguisher, the typeaof' combustibles present, and the fire _ loading in the room. The review determined the currently _ installed extinguisher is sufficient. Thus,_the A ' ' ' ' ---_.__._.u_ m-_____mA._____i -___.._m_m__.

Docket Number 50-346 License Number NPF-3 Serial Humber 1789 Page 2 alternate approach which reflects the existing plant configuration, has b(en evaluated and it has been concluded that there is no adverse impact on the manual suppression capabilities available for Room 320.

3 The SER tcquired the installation of vet pipe sprinkler systems 6 equipped with quick response type sprinklers in ten different fire 4 areas. The original installation was completed. This installation included special " fast acting sprinkler heads" in the Service Vater System Pump Intake Structure based on the specific conditions in that room. The sprinkler systems vere evaluated for compliance with NFPA 13, " Standard for the Installation of Sprinkler Systems",

and the Appendix R sprinkler systems, except for Scrvice Vater Valve Room 53, have been upgraded to resolve the code deficiencies as identified in the Toledo Edison letter Serial Number 1497, dated May 23, 1988. This upgrade included the replacement of the quick response type sprinklers and the special " fast acting sprinkler heads" with sprinkle s which comply with NFPA 13 requirements for the Appendix R Sprinkler Systems.

The method of Appendix R compliance in Room 53 (Fire Area BG) has been re-evaluated and it has been determined that en acceptable method of Appendix R compliance for Room 53 is provided by a three-hour fire barrier on the circuits for Service Vater Pumps 1 and 3 without requiring the sprinkler system.

The Appendix A sprinklar systems af fected by this SER require.aent are located in Corridors 209 and 304. These' systems were installed for coverage of specific hazards to redundant safe shutdovn components as identified in a September 7, 1978, site visit by the NRC (refer to Toledo Edison letter Log Number 350, dated October 3, 1978). These systems are installed _as committed, but they no longer protect safe shutdovn components.- Therefore, no modifications are planned for the sprinkler systems in Corridors 209 and 304 to meet the NFPA 13 standard for area coverage.

Toledo Edison's alternate compliance approaches, including the correction or . justification of NFPA 13 Code de"lations, provide equivalent or improved suppression capabilities.

5. The SER-required the installation of a vet pipe sprinkler system -

equipped with thermal-actuated type vater spray nozzles in the Cable Spreading Room (Fire Area DD). The original installation vas.

completed. The sprinkler sy? tem was evaluated for compliance with NFPA 13 " Standard for the Installation of. Sprinkler Systems" and the sprinkler system was upgraded to resolve:the code deficiencies identified in the Toledo Edison letter Serial' Number 1497, dated May 23, 1988. The thermal-actuated type water spray. nozzles were replaced with sprinklers which comply with NFPA 13 requirements.

This alternate approach reflects upgrades to correct NFPA 13 code deviations and results in an upgraded system that provides an equivalent or improved suppression capability.

6. The SER required that Door "508" have a 1% hour fire sating since it was part of the fire rated boundary for the Control Room complex. The correct door number has been determined to be "503" instead of "508". The original requirement for Door 503 was satisfied. This alternate approach deletes the cequirement for Door 508 to have a 1% hour fire ratirg and replaces it with Door 503. FHAR Aprendix E (Drawing A225F) (i.e., Control Room Com[dex Tire Area) va$ revised to redefine the fire rated boundary suen at the vall coe iining Door S08 is no lonFer part of the Control huom Complex fire ,oundary. Thus, Door 508 does not require a 1%

hout tire rating. Door 503 maintains the 1% hour rating requirement. Thi alternate approach reflecting the revised boundary is dt- 1 d in the THAR and it has been concluded that therc is no advers impact on the required fire boundary for the control Hoom comp

7. The SER required the application of a spray-on type fire proofing on the supports for four horir.ontal cable trays penetrating the 3-hour fire barrier at column line 0-F on elevation 602'0". In lieu of using a spray-on fire proofing, additional sprinklers have been installed to protect the supports and to prevent the powential associated degradation of the fire barrier between the Turbine Building and the Cable Spreading Room. It is noted that the location of the cable tray supports at column line 0-F and 602'-0" was incorrectly identified in the SER. The correct location is 9-F and 6038 -0". The additional sprinklers provide adequate cooling to ensure the integrity of the cable tray supports in the event of a fire in the area. The additional sprinklers vere installed in accordance with NFPA 13 requirements to assure that the associated fire barrier vill not be breached.

8. The SER required the application of a spray-on fire proofing on the supporting structural steel in mechanical and electrical penetration rooms (Rooms 208, 236, 303, 314, 402, and 427). In lieu of using a spray-on fire proofing, sprinklers have been installed in these rooms (see FHAR Sections 4.6.AB-(Room 208),

4.6.A (Room 236), 4.6.AB (Room 303), 4.6.A (Room 314), 4.6.DG (Room 402) and 4.6.DF (Room 427)). In response to Revision 6 of the FHAR, submitted by Toledo Edison letter Serial Number 617, dated May 15, 1980, the NRC accepted the use of the sprinklers in lieu of a spray-on fire proofing. This acceptance was documented in the-NRC's July 17, 1980 (Toledo Edison letter Log Number 582)..

Although FHAR Revision 6 provides justification for use of suppression systems as the means of protecting against an exposure fire for each of the rooms listed above, the July 17,.1980 NRC letter did not include Room 314 in.the list of those rooms for which structural steel fireproofing was not required. The alternate' approach reflects the use of sprinklers-to protect the supporting structural steel in Rooms.208, 236, 303, 314, 402 and 427. These systems were upgraded to satisfy NFPA.13 requirements.

~

Thus, the alternate approach provides adequate' assurance that the supporting structural steel capabilities vill not be compromised.

9. The SER required the application of a spray-on fire proofing on the supporting structural steel in the turbine building as determined by the turbine building thermal expansion nnalysis. Toledo Edison's alternate approach provides an equivalent level of structural steel fire protection using sprinklers.

Toledo Edison concluded that sprinklers vould provide an acceptable means of controlling a postulated fire and therefore reduce the potential for fire dat. age. This approach was provided in Toledo Edison's letter Serial Number 486, dated February 28, 1979, containing Revision 5 to the filar, but this approach was not reflected in the SER. Sprinklers were either added or previously existed fu Turbine Building !! eater Bays (FSA-3501, 4501, 5501, 6501, 7502), Turbine Building fleater Bay Roof Truss, Turbine Building Basement, Heezanine and Operating Floor (FSA-4105),

Turbine Building Poof Train Bay and Turbine Building Hetrology Laboratory (Het Lab) to provide fire protection and to prevent heating of portions of the structural supporting steel in the Turbine Building. The alternate approach requires sprinklers in the Turbine Building Heater Bays (FSA-3501, 4501, 5501, 6501 and 7502), and the Turbine Building Basement, Herranine, and Operating Floor (FSA-4105). The alternate approach does not require either sprinklers or spray-on fireproofing in the Turbine Building Roof Train Bay, Turbine Building Het Lab and Turbine Building lleater Bay Roof Truss to satisfy the requirements of the turbine building theroal expansion analysis as described below:

a. Turbine Building Roof Train Bay The sprinklers in the Turbine Building Roof Train Bay are at the 692 ft, elevation and provide coverage for 2400 sq.

ft of the Railroad Bay which is at the 585 ft. elevation.

The Train Bay is in the northeast corn 2r of the Turbine Building and two vall.1 of the Train Bay are exterior valls with the remainder open to the Turbine Building Operating Floor (elevation 623 ft.). Due to the open construction of the Train. Bay _and the height of the Turbine Building roof over the Train Bay, the sprinklers provide very limited fire suppression capability. The sprinkler system protects the roof steel and does not protect the Turbine Building structural steel. However, this does not alter the conclusion of_the turbine building expansion analysis that thermal expansion in the Turbine Building in limited to an acceptable level.

b. Turbine Building Metrology Laboratory (Het Lab)

The Het Lab includes a calibration _ lab and fire brigade k-locker room that is constructed.at the 623 ft. elevation on the Turbine' Building Operating Floor and is approximately l'0 ft. in height. Originally the. area was a lunch room and w

Docket Number 50-346 License Humber NPF-3 Serial Number 1789 Attachment 2 Page 5 an instrumentation and control shop, but has been converted to a calibration lab and fire brigade locker room with a significant reduction in the combustible loading. The minor amount of combustibles contained in this small enclosure on the Turbine Building Operating Floor vould not produce enough heat to cause unacceptable expansion of the supporting structural steel members considering the large volume and area of the Turbine-Operating floor and the installed smoke and heat vents in the Turbine Building ceiling. Thus, Toledo Edison has deleted the sprinkler system in the Het Lab as part of the requirement for protecting structural supporting steel in the Turbine Building. However,-this does not alter the conclusion of the turbine building thermal expansion analysis that the thermal expansion in the Turbine Building la limited to an acceptable level,

c. Turbine Building Heater Bay Roof Truss Two sprinkler systems were installed at the 692' elevation in the TurbAne Building Heater Bay area and cover the same area with one set of nozzles aimed upward and one set aimed downward. These sprinkler systems vere evaluated for compliance with NFPA 13 and vere upgraded to one system that resolves the-code deficiencies as identified la Toledo Edison letter ? trial Number 1497, dated May 23, 1988. The sprinklers in the Turbine Building Heater Bay Roof Truss are not required for satisfying the turbine building thermal expansion analysis while the sprinklers in the Turbine Building Heater Bay (FSA-7502) are required. This sprinkler system (FSA-7502) is in compliance with NFPA 13 (note: FSA-7502 was previously designated FSA-7501).

10. The SER required the installation of a fite detector in Room 233. Toledo Edison's alternate approach deletes the requirement for a detector in Room 233. Room 233 is one of the 25 rooms that comprise Fire Area G. . The FHAR Section 4.6.G and Drawing A222F shov-14 fire detection zones that comprise.the fire detection capability for Fire Area G. A review of Room 233 was -

performed which determined that a detector is not required due 4

to minimal fire loading (400 BTU /ft8) and no safe shutdown cables being routed in the room.- The room is inaccessible except'through concrete shield plugs from the room above. - The concrete 3hield plugs are normally in place. The lack of room openings and lov fire loading ensure containment of any postulated fite. This approach, reflecting the existing plant configuration, has been evaluated and there is no adverse impact i on the fire detection capability for Fire Area G.

11. The SER required-+.he installation of additional area type detection in the Fuel Handling Arec (Room 300).- Local detection is already provided in Room 300. A reviev.of Room 300 (Fire mm- ea_a_t-m--:-a.a---------w.we u

Docket Number 50-346 License Numler NPF-3 Serial Number 1789 Attachment 2 Page 6 Area V) was performed which determined that additional detection should be installed as stated in Licensee Event Report 86-030 Revision 1. dated March 23, 1988. Since the detectors are not required to resolve an Appendix R (safe shutdown) concern, the detectors are scheduled to be installed by the end of the seventh refueling outage. This schedule is consistent with that provided in Toledo Edison letter Serial Number 1595, dated December 2, 1988. This alternate approach requires the area type detection installation by the end of the seventh refueling outage, presently scheduled for late Fall, 1991.

12. The SER required the installation of in-tray, linear type, thermal sensing fire detectors inside all-the cable trays in the Cable Spreading Room (Room 422A). The original installation was completed.

In addition, the Cable Spreading Room contains fire area ionization type smoke detactors which vere upgraded to r'. solve the NFPA 72E, " Standard on Automatic Fire Detectors

ccJe deficiencies identified in Toledo Edison letter Serir.1 Number 1497, dated May 23, 1988. Based on the Cable Sprer. ding Room construction of a smooth ceiling approximately 8 ft. high and the upgrade to resolve the NFPA 72E dev*ations, the area Jonization typc smoke detectors provide adequate detection capability and the in-tray detectors are no longer required.

This alternate approach deletes the requirement for the in-tray, linear type, thermal sensing fire detectors. The upgraded area ionization type smoke detectors provide an adequate level of detection :apability in the Cable Spreading Room.

13. The SER required the installation of 8-hour emergency battery pack lights in Passage 241 (Fire Area G). In 1987, a lighting unit in Passage 241 was installed with the power supplied from a battery unit in Passage 227. The proposed revision clarifies that Passage 241 is illuminated without the 8-hour emergency battery pack being in the room. -This alternate approach, which ref;ects the existing plant configuration, ensures there is sufficient illumination.in Passage 241.

14. The SER required the installation of 8-hour emercency battery pack lights in Makeup Pump Room 225 (Fire Area AB). Instead of installing the lights in Room 225, the emergency battery pack lights were installed ~in the Vestibule (Room 226A) with light directed into Room 225 to provide illumination for access and egress in Room 225. The lighting from Room 226A is uninterrupted-because there is no door or other' intervening objects, which could' block- the light. Thus the emergency light is situated such'that its light beam provides-adequate-illumination to Room 225 for access and egress. In addition, an emergency lighting unit has been installed in Room _225 for Appendix R required manual-actions, This alternate approach, which reflects the, existing plant' configuration, ensures there is sufficient illumination in Room 225.for access and egress.

15. The SER required installation of a 1/2-hour fire rated barrier l (Kaovool) in the Service Vater (SV) Valve Room (Intake Structure

- Room 53) around the power and control circuits for the Service Vater valves (SV 2930, SV 2931) located in the service water diFeharge header. The original install.ation was completed but later removed. The affected valve was de-powered which negated the need for the fire barrier vrap. FHAP Section 4, Note 27 and Table 1 for Fire Area BG (Room 53) states that one of the four Service Vater Discharge Valves (SV 2929 through SV 2932) is normally open and depovered (controlled administratively) to ensure a SV return flow path is available following a fire in the area. The approach in the FHAR is an acceptable alternative to the installation of a 1/2-hour fire rated barrier around the power and control circuits for the Service Vater valves (SV 2930 and SV 2931). This alternate approach has been analyzed in the-FHAR and there is no adverse impact on the ability of the system to function as required for safe shutdown. !

16. The SER required the installation of a 1/2-hour fire rated.

barrier (Kaovool) in Passage 227 (Fire Area G)-around the circuits for the Train 1 Auxiliary Feedvater Pump suction valve FV 786 and the interlock to Service Vater valve SV 1382. The ,

original requirement was met by installing Kaovool barriera en conduit 27572A (cabling for the. interlock to SV 1387) cad on conduit 27708A (cabling for Auxiliary Feedvater Pump $6t' ion valve FV 786). FHAR Section 4.6.G (Passage 227) states that Train 2 equipment is assured available for safe shutdown which removes the need to utilize SV 1382 and FV 786 which are Train 1 valves. The alternate approach deleted the requirement 'or the 1/2-hour rated barrier (Kaovool). This alternate approach has been analyzed in the FHAR and there is no adverse impact on the safe shutdown capabilities.

17. The SER required the installation of a 1/2-hour fire rated barrier (Kaovool) in Passage 209 around the circuit for the Borated Vater Storage Tank (BVST) level instrumentation, Makeup Pump No. 2, and Train 2'BVST outlet valve. The original l

requirement was met by installing Kaovool barriers on conduit 28222A (cabling for Hakeup Pump No. 2), conduit 27670C (cabling for BVST outlet valve DH 07A), and on the four conduits j containing the four trainslof BVST level instrumentation. The l

alternate approach deleted-the requirement for the 1/2-hour L rated barrier (Kaovool).

For the Fire Area G (Passage'209) safe shutdown analysis,Tthe L High Pressure Injection (HPI) System takes; suction from the BVST l to maintain the water inventory in the Reactor Coolant System.

l Due to the large BVST volume (Technical Specification minimum of

482,778 gallons) and the limited water volume required to achieve cold shutdown,_it is not necessary to monitor.the BVST vater level to ensure that there is adequate BVST vater to -

achieve cold shutdown._ FHAR Section 4.6.G.5 states that HPI is the system that is assured for RCS injection'(level-inventory-

l Docket Number 50-346 License Number NPF-3 Serial Number 1789 Attachment 2 Page 8 and reactivity control) for safe shutdovn in this fire area.

The Makeup System serves as a redundant syrtem to the HPI and is l not required to assure safe shutdown in this fare area. filar l Section 4, Fire Area G, Table 1, identifies that there are procedural actions to manually verify /open Train 2 BVST outlet t

valve (DH 07A) for a fire in Fire Area G to ensure BVST l availability for safe shutdown. A separate study was performed to show ample time existed to perform the procedural actions.

" 's alternate approach which deleted the requirement for the ;

hn f-hour vraps, has been analyzed in the FHAR and there is no adverse impact on the safe shutdown capabilities.

18. The SER required the installation of 1/2-hour fire rated barriers (Kaovool) in Passage and Hatch Area 310 and 313 around the conduits for both trains of Component Cooling Vater (CCV) crossover header valves (CC 5095, CC 5096) and CCV return header from containment valves (CC 5097, CC 5098). The original barrier on conduits 46088B and 47342A, which contain Trains 1 and 2 power cabling respectively for CC 5095, CC 5096 and CC 5097, CC 5098 was installed. Originally, valves CC 5095, CC 5096, CC 5097 and CC 5098 vere protected to provide cooling for the Makeup Pumps and the immediate re-establishment of Reactor Coolant Pump'(RCP) seal cooling and seal return. This alternate ,

approach deleted the requirement for the % hour fire reted barrier for CCV crossover header valves'(CC 5095, CC 5096) and for CCV return header from containment valves (CC 5097, CC 5098).

FHAR Section 4.6.U.5 for Fire Area U (Passage and Hatch Areas 310 and 313) states that HPI is the system that is assured for ;

I RCS injection (inventory and reactivity control) for safe

! shutdown in this fire area. Therefore,-the Makeup Pumps are not required. The existing RCP seals have been replaced with a newly designed RCP seal. Based on test data, integrity of the new seal is maintained without seal cooling for eight hours.

After eight hours, RCP seal cooling and seal return vill be-l re-established. As part of the process of providing RCP seal l cooling and seal return, some-fire areas contain motor or air

! operated valves which could be exposed-to a fire in the area and l require manual repositioning.

These motor.or a': driven valve operators vould not be L mechanically impaired by a-fire in such a manner to prevent subsequent manual handwheel operation of the valves as discussed in Toledo Edison letter Serial Number 1757, dated Februcry 16 1990. The seal changeout'and the procedure revision to re-establish RCP seal cooling and seal return have beer completed.. Since the valves are not immediately required to

. achieve hot shutdown and adequate time is available for required manual actions, the fire barrier vraps for both. trains of Component Cooling Vater (CCV) crossc/er header valves are not required. Thus, this alternate approach has-been analyzed and there is no: adverse impact on the safe shutdown capabilities.

19. The SER required the instcllation of a 1/2-hour fire rated barrier (Kaovool) in the Service Vater Pump Room (Room 52) around the circuits for the Service Vater Pumps (1, 2 and 3) and for the Service Vater valves on the return line to the forebay !

(SV 2930) and the cooling tower makeup (SV 2931). The service water valve motors (SV 2930, SV 2931) located in Room 53, vere also enclosed with a 1/2-hour fire rated barrier. The original installation was completed. The alternate approach deleted the requirement for the 1/2-hour fire rated barrier (Kaovool). filar Section 4, Note 27 for Fire Area BF states that one of the four SV Discharge Valves (SV 2929 through SV 2932) is normally open and depovered (controlled adm.%istratively) to ensure a SV return flow path is available following a fire in the area.

filar Section 4, Note 27 for Fit Area BF states that the Backup Service Water Pump, which is in Fire Area BD, is available as the backup for the three Service Vater Pumps in Fire Area BF.

The Backup Service Vater Pump operation is not affected by a fire in Fire Area BF. Therefore, the Kaovool barriers on the conduits for the Service Vater Pumps and valves and the Service Vater valve motors are no longer required. The approach in the filar is an acceptable alternative to-the 1/2-hour rated barrier. ;

This alternate approach has been analyzed in the FHAR and there is no adverse impact on the ability of the system to function as required for safe shutdown.

20. The SER required the installation of a 1/2-hour fire rated barrier (Kaovool) in CCV pump and Heat Exchanger Room (Room 328) j around the circuits for the CCV puh.ps (1, 2, 3) and power and control circuits for the CCW crossovec valves (CC 5095, CC 5096). The underside of the valve motors vere also required to be protected with a 1/2-hour fire rated barcier. The original installation was completed. This alternate ?proach deletes the requirement for the 1/2-hour fire ratsJ barrie for the CCV crossover valves (CC 5095, CC 5096), but retains the fire barrier vrap requirement for the CCV pumps circuits.

FHAR Section 4.6.T.5, for Fire Area T states that Hakeup and-Purification System (HUPS) is the system that is assured for RCS injection (inventory and reactivity control) for safe ~ shutdown.

L As discussed in Item 18 above, procedural actions to open/ verify.

l valves CC 5095'and CC 5096 are required to restore RCP seal j cooling and since time is available for manual actions, the h e barrier wraps are not required. The Kaovool vrap required for _

the CCW Pump circuits as listed in FHAR Section 4, Table 1, for-Fire Area T has been replaced with a one-hour fire rated wrap-which is more durable than the Kaovool wrap.. Thus, this~ .

alternate approach har, been analyzed in the FHAR and there.is no adverse impact on the safe shutdown capabilities.

BASES OPERABILITY of the Appendix R related fire uetection instrumentation

, ensures that adequate warning capability is avellable for the prompt detection of fires. This capabilitj is required in order to detect anu locate fires in their early stages. Prompt detection of fires vill reduce the potential for damage to_ redundant safe shutdown equipment required in the event of a fire and is an integral element in the overall DBNPS fire protection program.

The number of OPERABLE instruments in certal.. *i2% detection rones may be less than the number of installed instrt *nts by approximately -10 percent without s3cnificantly rede-ing th effeettveness of the system as long as 1

no two adjacent instruments are inoperabla. Table 8.1 specifies the minimum nutber of OPER! LE instruments necessary for the zone to be considered 0?ERABLI. Tne increased time delay for detection of a fire in the fire detection zones allowed to1 operate with a reduced number of instruments vould be ninimal since the typical power plant fire (cable insulation or oil) produces large amounts of smokt which would quickly spread and be detected by the remaining instruments.

In the event that a portion cf the required firi detection instrumentation is inoperable, monitoring the affected areas, as specified-in the ACTION statements above, is required to provide detection espability until the inoperable instrumentation is restored to OPERABILITY. If the affected area is inaccessible, than alternate compensatory measures are taken. The Containment annulus area has locked access doors wi th neutron shielding located across the opening such that access viinin one hour of determination et inoperable fire detection is physically impractical.

Therefore, a longer access time consistent with the inspection interval of eight hours sas established.

BASES The OPERABILITY of the Appendix R related fire suppression systems ensures that adequate fire suppression capability 1: r.~41stle to confine and extinguish fires occurring in those portions of the facility containing redundant safe shutdt,vn equipment required in the event of a fire. The tire suppression systems consist of the water supply system, sprinkler systems and vater curtain deluge systems. The collective capability of the fire sunpression systems is acequate to minimize potential damage to redundant safe shutdown equipment required in the event of a fire and is a major element in the DBNPS fire protection program.

The Ultimate Heat Sink is confirmed OPERABLE in MCDES 1, 2, 3 and 4 per Technical Specification 3/4.7.5 and requires plant shutdown if. it is inoperable. Therefore, the only additional action or surveillance specified in the Operating Specifications addresses MODES 5 and 6.

The Ultimate Heat Sink level of 562.0 feet or above is maintained consistent in MODES 5 and 6 vith the Technical Specificacion 3/4.7.5 requirement, even though this is above the level needed for diesel driven fire pump OPERABILITY. The intake forebay level necessary for proper priming and/or operation of the diesel driven fire pump at 150 percent design capacity, with maximum vater temperature of 85'F is 548'-10". In o: der to minimize the introduction of additional surveillance requirements the conservative single value for diesel driven fire pump OPERABILITY of l 562.0 feet was chosen, since this value is already assured in MODES 1, 2, 3 and 4.

C. The non-supe: vised circuits that are associated with the detector alarms of each of the above fire detection instruments and routed between the local panels and the Control Room snall be demonstrated OPERABLE at least once per 31 days by performance of a CHANNEL FUNCTIONAL TEST.

BASES OPERABILITY of the Appendix A related fire detection instrumentatiea ensures that adequate warning capability is available for the prompt detection of firss. This capability is required in order to detect and locate fires in their early stages. Prompt detection of fires will reduce the potential for damage to redundant safe shutdown equigxnent required in the event of a fire and is an integral element in the overall DBNPS fire protection program.

The number of OPERABLE instrument (s) in certain fire detection cones may be less than the nunber o' installed instrtuencs by Septoximately 10 percent without significantly reducing the effectiveness of the system as long as no two adjacent instruments are inoperable. Certain fire detection renes were instnlled with redundant instruments which allow for up to a 50 percent reduction in OPERABLE instruments while maintaiMag the tone OPERABLE. Table 8-3 specifies the minimum number of OPERABLE instruments necessary for the tone to be considered OPERABLE. The increased time delay for detection of a fire in the fire detection zones allowed to operate with a reduced number of inntraments would be minimai since the typical power plant fire (cable insulation or oil). produces large amounts of smoke which would quickly spread and be detected by the remaining instruments.

In the event that a portion of the required fire detection instrumentation is inoperable, monitoring the affected areas, as specified in the ACrIW statements above, is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY. The use of OPERABLE sprinkler / deluge systems for compensatory measures provides flow alarm indication to the Control Room diractly.

yard fire hydrants. 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 DBNPS fire protection program.

In the event that portions of the fire suppression systems are inoperable, compensatory measures are required until the inoperable equipment is restored to service. An hourly fire vatch vill adequately compensate for loss of a sprinkler / deluge system when the area contains significant quantities of combustible loading (defined as greater than 60,000 BTU /sq.

ft.) or potential fuel _ oil / lube oil hazard areas within_the plant structures as identified on Table 8-4 The outside-areas and areas vithin the plant structures that do not contain-significant quantities of combustible loading must either have OPERABLE fire detection instrumentation in the affected area or an hourly fire vatch to adequately compensate for loss of a sprin r/ deluge system. These systems are not used to protect redundant sate snutdown equipmen'. or. components so the potential hazard to public health and safety is-reduced.

The sprinkler / deluge system flow path is defined as'the' path from the fire suppression deluge nozzle vater system in the (see Section 8.1.3 Basis)1tc the last sprinkler /

line and ' es not include vents,-drains,. inspector test connections or.other system branches not. leading to sprinklers ~or deluge nozzles.

All hourly fire vatches shall be performed at -intervals of sixty minutes with a margin of fifteen minutes (+ fifteen minutes). A continuous fire vatch requires that a. fire vatch be intthe specified area at least once ever r. fif teen minutes with a margin of rive minutes -(+ five minutes). The use of any part.of the fifteen minutelor:five minute margin does not. alter the schedule for any subsequent hourly or: continuous-(fifteen minute) firc vatch, respectively.

SURVEILLANCE PICUIREMDCS Each of the above required fire barriers, including sealing devices, shall be verified OPEPABLE by:

A. Performing *a visual inspection of the exposed surfaces of each fire-rated wall , floor and ceiling, electrical raceway fire enclosure and structural steel fire-proofing at least once per 18 months.

B. Performing a visual inspection of each fire door, fire damper and associated hardware at least once pc 18 months.

C.

Performing a visual-inspection of at least ten percent of each type of sealed penetration at least once per 18 months. If the penetration (s) is determined to be inoperable, declare the affected penetration (s) inoperable and perform a visual inspection. of. an additional ten percent of the degraded type of sealed penetration. This inspectie.. process shall continue until a ten perem t sample with no visually apparent adverse changes in appearance o'. changes from the as-built condition are found et until all required-sealed penetrations of the degraded type have been inspected.

Performing a functional test that verifies the operation of automatic hold-open and release mechanisms upon full openings, and latch and closing mechanisms upon full and partial openings, at least once per 18 months.

BASES The OPERABIT.ITY of the Appendix A related fire barrier ensures that fires will be confined or adequately retarded from spreading to adjacent fire areas. This design feature minimizes the possibility of a single fire rapidly involving several fire areas of the DBNPS prior to detection and extinguishment. The fire barriers are passive elements in the CBNPS fire protection program.

Fire barriers, including sealing devices, fire doors, electric raceway enclosures, structural steel fireproofing and dampers, are considered CPERABLE when the visually observed condition is the same as the as-designed condition. The as-designed condition of each fire barrier is based on a tested configuration or a configuration analyzt;3 to withstand the fire hazards-associated with the fire area. For tnose fire barriers that are not in the as-designed condition, an evaluation shall be per-formed to show that the fire rating of the fire barriers is not degraded and that the barrier is OPERABLE or the ACTION statement shall be entered-A one-sided inspection of barriers is permitted when physical constraints or ALARA considerations (defined a0 the barrier being inside a high radiation area (> 100 mrenvhour exposure to personnel) regardless of p; .nt operational status) render the opposite side inaccessible. For these barriers, the inaccessible side is considered to be unexposed for inspection. Any barrier that requires equipment to be unbolted or dismantled, destruction of a ;overing surface, of use of cra' ns or hoists i

to remove plugs to gain access is also considered to be uN xposed.

All hourly fire watches shall be performed at intervah of sixty minutes with a margin of fif teen minutes (+ fif teen minutes).- A continuous fire watch requires that a fire watch be in the specified area at least once every fif teen minutes with a margin.of five' minutes (+ five minutes). The use of any part of the fifteen minute or five minute margin does not alter the schedule for any subsequent hourly or continuous-(fifteen minute) fire watch patrol, respectively. Rooms that are continuously staffed or are visible to the continuously staffed area do not require a separate fire watch since the personnel normally in the area serve that function, for fire barriers the only reas this would apply is the Control Room area (Rooms 502, 504, 505, 506, SM , 511 and-512) and the central Alarm Station area (Room 434).
