1. Once each week verify electrolyte level and voltage-_is within specification.
2. Once every three months verify the specific gravity of each cell is within specifications, t
3. Once every 18 months -inspect the batteries, battery racks, and - '

The minimum number of fire detectors required to be OPERABLE in each fire zone are feet 4+na14y-tested following the manuf+etur+r temsnufaytsrefjid recommendations-each-cin cat 4*e, except for those located inside the primary containment which are tested during each COLD SRUTDOWN exceeding 24~ hours-unless performed during the previous six months. These tests-teste are performed by the plant staff. Other fire detectors will be tested at an.

interval which experience has shown to be necessary to assure reliable operation. Every six months an alarm circuit check is performed. This-check can be performed in conjunction with detector functional tests. All-circuitry is also provided with automatic supervision for opena and ground

  • faults.

Fire pumps are tested each month to verify OPERABILITY. Test starting of . ,

the screen wash pump is not required since it is normally' in service. Each fire pump is manually started and operated for at least 15 or 20 minutes with pump flow directed through the recirculation test line. Every 18 i

months the OPERABILITY of the automatic actuation logic for.the fire pumps l

and the-screen wash pump is verified and the performance of each pump is verified to meet system requirements.- The specified flush and valve lineup check provide assurance that the piping system is capable of supplying fire suppression water to all safety related areas. When one of the pumps is inoperable the operable purups are run daily to verify OPERABILITY until all pumps are once again available, FIRE SUPPRESSION WATER SYSTEM flow tests will be done at least every three years to verify hydraulic performance. The testing will be performed using Section II, Chapter 5 of the Fire Protection llandbook, 14th Edition, as a procedural guide. The test is generally performed in conjunction with - .

Insurance inspections.

Surveillance specified for each spray and sprinkler system is intended to --

assure that the systems will function as designed when they are needed.

Functional tests are conducted at 18 month intervals on those ' systems provided with test facilities.

The testing specified for the. relay and cable spreading room CO 2system provides assurance that the CO2 inventory is adequate to extinguish a fire in this area and that the system is capable of automatic actuation, llose stations and yard hydrant hose houses are inspected monthly :to verify that all required equipment is in place. Caskets in hose couplings are inspected periodically and the hose-is pressure tested. Pressure testing-of

B.4.16 2 RE" 91 10/27/S9 4.16 FIRE DETECTION AND PROTECTION SYSTEMS Bases continued outdoor hose is conducted more frequently than indoor hose because of the less favorable storago conditions. OPERABILITY of hose station isolation valves is verified every three years by pr-tially opening each valve to verify flow. All of these tests provide a high degree of assurance that each hose station will perform satisfactorily after periods of standby s e rvic e .

Plant fire barrier walls are provided with seals for pipes and cables whhre necessary. Where such seals are installed, they must be maintained intact to perform their function. Visual inspection of each installed seal is-required every 18 months and .af ter seal repair. A visual inspection-following repair of a seal in the secondary containment boundary is sufficient to assure that seal leakage will be within acceptable limits.

Qbiective To verify the operability of instrumentation and plant systems used for fire detection and protection of nuclear safety related structures, systems and components.

Specification A. Fire Detection Instrumentation

1. The minimum number of ion and flame fire detectors required in each l zone specified-in Table TS.3.14 1 shall be functionally tested once every six months, except that, for ion detectors that are addressable from a dedicated control panel, the proper sensitivity ;shall be varified quarterly with the minimum number of addressable fire detectors specified in Table TS.3.14-1 functionally tested once every-two years.

A minimum of 20% of the restorable thermal detectors will be tested on an annual schedule with all thermal detectors tested at least once per 5 years.

The minimum number of fire detectors required in areas which are inaccessible during operation shall be functionally tested during each cold shutdown exceeding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless performed during the previous six months, however, tne outage need not be extended solely for completion of these tests.

2. The alarm circuit for the detectors reqtired in each one specified in Table TS .3.14-1 shall be tes ted every six months .

B. Fire Suppression Water Svstem

1. The system shall be verified operable as follows:
a. Operability of the diesel-driven fire pump starting battery shall be demonstrated by:
1. Once each week verify electrolyte level and voltage is within specification.
2. Once every three months verify the specific gravity of each cell is within specifications.
3. Once every 18 months inspect the batteries, battery racks, and electrical connections for damage or abnormal deterioration.

B.4.16-1 4.16 FIRE DETECTION AND PROTECTION SYSTEMS Eases o There are two configurations for ion fire detectors in the plant, those which are addressable by a dedicated control panel (a programmable logic controller) and those which are not. An addressable detector allovs for. a '

more frequent check of sensitivity which is. generally more informative than a functional test. However, the functional test may be substituted forfthe sensitivity test if desired (e.g. , when the sensitivity check function is unavailable) . .

The minimum number of fire detectors required to be OPERABLE in each fire zone are tested following the manufacturers' recommendations, except for- :l.

those located inside the primary containment which are tested during each COLD SHUTDOWN exceeding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless performed during the previous six months. These tests are performed by the plant staff. Other fire detectors . l~

will be tested at an interval which experience.has shown to be necessary to assure reliable operation. Every six months an alarm circuit check is performed. This check can be performed in conjunction with detector functional tes ts. All circuitry is also provided with automatic supervision for opens and ground faults.

Fire pumps are tested each month to verify OPERABILITY. Test starting of the screen wash pump is -not required since it is normally in service. Each fire pump is manually started and operated for at least 15 ct 20 minutes with pump flow directed through the recirculation test line. Every 18 months the OPERABILITY of the automatic actuation logic for the fire pumps" and the screen wash pump is verified and the performance-of-each pump is verified- to meet system requirements. The specified: flush and> valve. lineup check provide assurance that the piping system is capable of supplying fire:

suppression water toEcl1 safety related_ areas. When one of the pumps isL_ ,

inoperable the operable pumps are run daily to varify OPERABILITY until'all pumps are once again available.

FIRE SUPPRESSION WATER SYSTEM flow' tests will be done at least-every_three-years to-verify hydraulic performance. The testing will be performed using--

Section II, Chapter 5 of the Fire -Protection Handbook.14th Edition, as a procedural guide. The test _is generally performed in conjunction with' i insurance inspections.

Surveillance specified for each spray and sprinkler system is intended. co assure that the systems'will function as designed when they are needed.

Functional tests are conducted at 18 month intervals on those systems provided with test facilities.

The testing specified for the relay and cable spreading room CO2 system :

provides assurance that the CO2 inventory is adequate to extinguish a fire in this area and that the system is capable of automatic actuation.

each hose station will perform satisfactorily after piiriods of standby ,

service.

Plant fire barrier walls are provided with seals for pipes and cab 1cs where nec essary. Where such seals are installed, they must be maintained intact to perform their function. Visual inspection of each installed seal is required every 13' months and after seal repair. A visual inspection

,- following repair of a seal in the secondury containment boundary !s sufficient to assure that seal leakage vill be within acceptable limits.
