3.14-4 PROPOSED
Basis:
The fire protection system has'the capability to extinguish any probable fire which might occur at the station. The system is designed in accordance with the standards of the National Fire Protection Association.
Procedures have been developed for fighting fires in all the plant areas and are contained in the plant's emergency procedures.
Fire prevention is controlled by administrative methods to prevent accumulations of combustible materials and to practice good safety methods. Periodic practice exercises will be employed to insure plant personnel are familiar with the proper corrective procedures.
Detection is located in all areas of the plant containing safety related equipment and in areas containing large amounts of combustible or flammable materials. Actuation of fixed suppression systems and early warning alarms are provided by these detectors.
Fire barriers are located throughout the plant to separate major areas from each other and also to separate certain safety related areas from the remainder of the plant. These are designed to stop a fire from propagating from one area to another. All penetrations in these barriers are sealed with appropriate materials to match the requirements of the barrier.
Normal fire protection is provided by a fixed fire-fog system, fixed Halon 1301 system, sprinklers, hose lines, and portable and wheeled extinguishers suitably located in the required areas.
Readily accessible 1-1/2 inch rubber covered hose lines and the continuous flow type hose reels are distributed throughout station so that. all areas in the station are within 20 feet ofof a fog nozzle when attached to not more than 125 foot lengths hose. All nozzles are 1-1/2 inch variable fog-off nozzles.
Water to the fire system is supplied via the header by two vertical, centrifugal fire pumps of 2000 gpm capacity each; One 'a ofcombustion these pumps is driven by an electric motor and the other by engine. Both are automatic starting through fire pump controllers with indication, alarm and manual starting from the central control room fire panel. The combustion engine local fuel supply capacity is designed for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of operation.
A fire header is installed of sufficient size to deliver an adequate quantity of water throughout the plant at a pressure of no less than 75 psi at the highest nozzle.
The header system is normally pressurized through the use of a hydro-pneumatic tank using house service air and having an active water capacity of 10,000 gallons. Loss of header pressure and/or opening of any deluge system activates the fire pumps and the alarm system.
- 3. 14-5 PROPOSED
A backup:fire suppr'ession water system would be used to provide protection in the event the fire suppression water system were inoperable. A backup system could, for example, be comprised of a backup pump, the yard hydrant system supplying water to wall hydrants, or other equipment or measures.
The yard hydrant on the south-east corner of the yard'oop provides the secondary fire suppression capability for the transformers and the primary fire suppression capability for the .standby auxiliary feedwater building.

Attachment 3 In response to the NRC's Fire Protection Safety Evaluation, dated February 24, 1979, and its supplements, a number of modifi-cations and additions have been provided for the fire protection systems at Ginna. The proposed amemdment adds Technical Specifi-cations for these fire protection system modifications. The proposed changes are consistent with Standard Technical Specifi-cations. The changes do not affect plant effluents nor do they affect the authorized power level of Ginna.
Attachment C The proposed changes do not require .a fee. The changes are the result of modifications previously reviewed and approved by the NRC under its review of fire protection systems. Thus, this change is the concluding portion of a previous review by the NRC and not a new request for review. Further, since the requirements for these systems have already been established, no new technical or safety issues are raised by this submittal.
