--.--VYNPS.Bases:. 3.13/4.13 Fire Protection SystemsOn May 11, 1976, Vermont Yankee received a letter from the NRC requesting that an in-depth evaluation of theexisting fire protection systems be performed using Branch Technical Position (BTP) APCSD 9.5-1 as a guide. Concurrenwith this evaluation a fire hazards analysis of the entire plant complex was required. In an effort to clarify the BTP anAppendix A was subsequently issued to specifically address operating plants. Enclosed with this Appendix the NRCrequested that proposed Technical Specifications on fire protection also be submitted. The subject section 3.13/4.13 andthe following specific bases are those spelfications evolving from these efforts.A.The smoke, heat and flame detectors provide the early warning fire detection capability necessary to detectproblems in vital areas of 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.The Vital Fire Suppression Water System, CO2 systems, sprinkler systems and foam systems specifications areF and G. provided to meet pre-established levels of system operability in the event of a fire. These systems provide theB,C,D,necessary protection to assure safe reactor shutdown.vital fire suppression systems are operable.E.Periodic surveillance testing provides assurance thatVital fire barrier penetration fire seals are provided to assure that the fire resistance rating of barriers isnot reduced by a penetration. Surveillance inspections shall be performed to insure that the integrity of theseseals is maintained.The diesel fire pump has a design consumption rate of 18 gallons of fuel per hour; therefore, 150 gallonsprovides for greater than 8 hours of operation. Additional fuel can be delivered in about one hour andadditional fuel is on site. When the equipment prote.:ted by the fire protection systems is not required to beoperable, the specifications governing the fire protection system do not apply.i187-m
