N ej VYNPS PAfrS 3.13 & 4.13 TIPE PROTrcTION SYSTEMS i
on May 11, 1976, Vermont Yankee received a letter from the NRC requesting that an in-depth evaluation of the existing fire protection systems be performed using Branch Technical Position (BTP) APCSB 9.5-1 as a guide.
Concurrent with this evaluation a fire hazards analysis of the entire plant coglex was required.
It an effort to clarify the BTP an Appendix A was subsequently issued to specifically address operating plants.
Enclosed with this Appendix the NRC requested that proposed Technical Specifications on fire protection also be submitted.
The subject stetion 3.13/4.13 and the following specific bases are those specifications evolving from these efforts.
A.
The smoke, heat and flams detectors provide the early warning fire detection capability necessa y to detect problems in vital areas of l
the plant.
Surveillance requirements assure these sensors and their associated instruments to be operable. When the equipment protected by the detectors is not required to be operable, specifications covering the sensors and instruments do not apply.
1 B,C, The Vital Fire Suppression Water System CO 2 systems, sprinkler D.F, systems and foam systems specifications are provided to meet and pre-established levels of system operability in the event of a fire. These systems provide the necessary protection to casure G
safe reactor shutdown.
Periodic surveillance testing provides assurance that vital fire suppression systens are operable.
The east and west switchgea
'ooas low pressure CO2 storage tank Technical Specification min..aum level of 50% provides for sufficient CO concentration, pantity to schieve and maintain design 2 in accordance with NFPA 12 (1993), in the east or west switchgwar rooms. The Technical Specification minimum tank pressure of 270 psig will provide the minimum pressure to meet system design.
1 E.
Vital fire barrier penetration fire seals are previoed to assure that the fire resistance rating of barricts is not reduced by a penetration.
Surveillance inspections shall be performed to insure that the integrity of these seals is maintained.
The diesel fire pump has a design consumption rate of 18 gallons of fuel per hours there. tore, 150 gallons pr vides for greater than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of operation.
Additional fuel can be delivered in about one hour and additional fuel is on site.
When the equipment protect.ed by the fire protection systams is not required to be operable, the specifications governing the fire protection system do not apply.
