In the event that po ions of the fire suppressi systems are inoperable, alternate backup fire fighti equipment is requir to be made available in the affected areas until the in erable equipmen is restored to service. When the inoperable fire fighting equi ent is int ded for use as a backup means of fire suppression, a longer perio f ti is allowed to provide an alternate means of fire fighting than if the ino le equipment is the primary means of fire suppression. The surveillance requiremen provide ass nces that the minimum OPERABILITY requirements of t fire suppression stems are met. An allowance is made for ensuring a suff' ient volume of halon in he halon storage tanks by verifying the weight d pressure of the tanks.

The electric motor-driven fire. pump is supplied powerLthrough a motor control center located in the water treatment building. 'The power: supply circuit to the electric. motor-driven fire pump is protected by a-load center supply circuit breaker, a load center feeder circuit breaker, and_an electric fire. pump motor controller circuit brenker. Selection and setting of the e' protective trip devices for the aforementioned circuit breakers is.in-accordance with the guidance provided in NFPA 20-1978 and has been~ approved for-Grand Gulf's use by.American Nuclear Insurers (ANI). The electric fire pump motor controller circuit breaker pro-vides for instantaneous'short circuit protection and time delayed _ locked rotor current protection. The. trip setting (adjusted to the manufacturer's recommendation) does not permit I C' a circuit breaker trip at locked. rotor-current (LRC) unless LRC is sustained for at least 13 to 19 seconds. ' Locked rotor current (1050 amps) would be supplied for two to three times the normal starting time (5 to 6 seconds), permitting the normal starting of the motor without tripping the electric fire pump motor controller circuit breaker. This protective trip setting meets the guidance-provided in NFPA 20: the electric fire pump motor controller circuit breaker shall have a. time delay of not over 20 seconds, and the breaker shall.-permit normal starting of the motor without~ tripping. Additional short circuit and cable protection is achieved by providing protective trips of the load center supply-circuit breaker and the load center feeder breaker. The load center supply circuit breaker will not trip unless the sum of the LRC and the total'of the other full load ~ currents from loads connected to the load center are maintained for at least 40 to 65 seconds. The load center' feeder breaker (which feeds'the electric fire pump controller) will not trip unless'LRC is-maintained for at least 27.to 40 seconds. Therefore, the load center supply and the-load center feeder circuit breakers will not open earlier than the electric; fire. pump motor controller. 1 circuit breaker.

Each fire hydrant is provided with an isolation valve in order to isolate the hydrant in the event of physical damage and/or mechanical malfunction. Provided for each hydrant is a hose house equipped with 250 feet of 2-1/2-inch, lined fire hose, two 2-1/2-inch adjustable spray nozzles, one prybar, spanner wrenches, adjustable hydrant wrenches, and one fire axe. The fire water pumps are capable of providing water to any point in the station with the shortest leg of the main fire water loop out of service. The fire water system in the control building functions pri-marily as a backup fire fighting source. The water supply to the diesel generator building provides both the primary and backup fire fighting source. The water suppression systems and standpipes in the control building are supplied from a single connection from the underground fire water loop. The water suppression systems and standpipes in the diesel generator building are supplied from a single connection from the under-ground fire water loop. Therefore, a single line break in the loop connection would only negate all permanent water fire P t T suppression systems in the respective buildings. However, a ( / number of alternative backup measures are available in such an event. Located adjacent to the diesel generator building are outdoor hose houses. Section valves in the underground fire loop allow yard fire hydrants to operate even if the single building connection is lost due to a break in the line. In addition to the outdoor hoses, multiple 1-1/2 inch hose streams are acces-sible to the diesel generator building from the auxiliary ,' building. In the event that a break occurred in the control building fire water loop connection, operation of the gaseous fire suppression systems would not be affected. Portable water extinguishers are available throughout the building and provide a backup to the gaseous suppression system. Areas normally served by water suppression systems can be reached by multiple 1-1/2 inch hose streams from the turbine building. A hose connection has been installed in the standby fresh air filter deluge connections to enable connecting the turbine building fire hose and utilizing the turbine building fire loop as a deluge source.

_~ GG UFSAR O CMANGES -THIS PAGE 9B.10 QUALITY ASSURANCE y The GGNS fire protection system goes through two major phases .from design to operational status. These phases are: .(1) design, procurement, and construction; and (2) startup testing and operation. Appropriate quality assurance programs and requirements are applied to the fire protection system during each phase. The QA program applied to each phase addresses the 10-point QA criteria presented in Section C of Appendix A to Branch Technical Position APCSB 9.5-1. Furthermore, in each' phase, the QA activities are under the management control of the' appropriate QA organization. Management control, as used here, is defined as the authority and responsibility for establishing,-control-- ling, and verifying the implementation and adequacy of the fire protection QA program. i During the design, procurement, and construction phases of'the fire protection system, the fire protection QA. program is under- + the management control of the Bechtel Grand Gulf QA organization. This program has been developed to ensure that the GGNS design is of sufficient quality to meet its design function. Table 9.5-11, Section C, has been revised to provide.the QA program scope and description. During this phase, the MP&L Director of Quality i Assurance has the responsibility for verifying the implementation j (<- and adequacy of the Bechtel fire protection QA' program chiefly . ' ~ through a documented audit program. During the operational phase (startup,-preoperational testing, and operations), the fire protection QA program.is-under the management control of the MP&L QA organization. The specific j organizations which exercise this control are:-Quality Assurance, Nuclear Plant Engineering, Plant Technical Support (Engineering), Maintenance, and Operations. Section C of Table 9.5-11 provides the scope and description of the QA Fire Protection Program applicable during the startup and operational ~ phases. a 9B.11 SYSTEMS Section 9.5.1 of the UFSAR describes the Fire Protection System. 9B.12 FIRE HAZARDS ANALYSIS i The Fire Hazards Analysis is referenced by Appendix 9A to the 1 UFSAR. i 9B.13 ANALYSIS OF SAFE SHUTDOWN IN THE EVENT OF A MAJOR FIRE tal analysis of safe shutdown in the event of a major fire is discussed in Appendix 9C. i s 9B-13 Rev. 1 12/86 i ? .--x. .. - ~ -
