Dear Ms. Adensam:

Re: Nine Mile Point Unit 2 Fire Protection Program FSAR/

Technical Specification Changes Docket No. 50-410 Niagara Mohawk Power Corporation has evaluated a program which incorporates our Fire Protection Technical Specifications into the Final Safety Analysis Report (FSAR). This material addresses the, requirements of Generic Letter 86-10. Niagara Mohawk Power Corporation intends to concurrently amend the Final Safety Analysis Report, by incorporating our Fire Protection Technical Specifications into the Final Safety Analysis Report Appendix 9A and removing the fire protection-related sections from the Technical Specifications. As a result, the Fire Protection Program will be described and controlled through the Final Safety Analysis Report, rather than through the Technical Specifications.

It 1

is Niagara Mohawk's intent to carry out all of the changes necessary to place the Fire Protection Program into the Final Safety Analysis Report prior to issuance of the full power license.

Nine Mile Point Unit 2 FSAR Each of the above-required fire doors shall be verified operable by inspecting release and closing mechanism and latches at least once per 6 months, and by .

verifying:

a. At least once per 7 days, that each locked-closed fire door is closed.

b. At least once per. 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , that doors with, release mechanisms are free of obstructions and performing a functional test of these mechanisms at lease once per 18 months.

c. At least once per 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , that each unlocked fire door is closed.

The operability of the fire barriers and barrier penetrations ensures that fire damage will be limited. These design features minimize the possibility of a single fire involving more than one-fire area before it is detected and extinguished. The fire barriers, fire barrier penetrations for conduits, cable trays and piping, fire dampers, and fire doors are periodically inspected to verify their operability.

Fire barriers with a fire resistance rating of three hours are provided to separate:

1. Safety-related areas from nonsafety-related areas.

2. Redundant divisions of safety-related systems from each other.

In most cases, this is accomplished with three-hour rated fire barriers. However, within the reactor building and primary containments, safety-related cables and equipment are spatially separated by locating them on opposite sides of the structures.

Hhere cables pass from the north side of the reactor building to the south side, cable trays are provided with sprinklers and the 20 ft.

fire break zone is provided with area sprinkler protection.

Appendix 9B evaluates the Unit 2 physical separation characteristics with regard to equipment, cabling, controls, and instrumentation required for shutdown.

3. Certain significant hazards within each safety-related division, e.g., divisional switchgear and safety;related pumps.

4. Unit 2 from Unit 1.

The administration building and access tunnels shared between Unit 1 and Unit 2 have three-hour separation fire barriers and appropriate fire protection.

9A.3.5.7.2 Sealed-beam Battery Powered Lights Sealed-beam battery-powered portable hand lights have been provided for use by the fire brigade and other operations personnel required to achieve safe plant shutdown.

9A.3.5.7.3 Emergency Communications The plant emergency communications consist of a page-party/public address (PP/PA) system with emergency evacuation signals and other emergency alarm throughout the plant, a maintenance and calibration communication (M/CC) system with plug-in jack outlets throughout the plant, a dc power supply and portable headsets, and a sound-power communication system (SPC) that utilizes portable sound-powered headsets and does not require any plant electrical power. Details of these systems are given in Section 9.5.2.

9A.3.5.7.4 Portable Radio Communications The portable radio communication system utilizes hand-held portable radios operated on UHF and VHF band frequencies. The radios are powered by rechargeable batteries. A pre-operational test will be conducted to ensure that the frequencies used for portable communications systems will not affect

'he actuation of protective relays. If repeaters are used, they will be suitably protected from exposure to fire damage.

9A.3.6 Fire Detection and Suppression 9A.3.6.1 Fire Detection As a minimum, the fire detection instrumentation for each fire detection zone shown in Table 9A.3-18 shall be operable whenever safety-related equipment protected by the fire detection instrument is required to be operable.

SURVEILLANCE RE UIREMENTS:

Each of the above-required fire detection instruments which are accessible during unit operation shall be demonstrated. operable at least once per 6 months by performance of a channel functional test. Fire detectors which are not accessible during unit operation shall be demonstrated operable by the performance of a channel functional test during each cold shutdown exceeding 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months unless performed in the previous 6 months.

The NFPA standard 72D supervised circuits supervision associated with the detector alarms of each of the above-required fire detection instruments shall be demonstrated operable at least once per 6 months.

The nonsupervised circuits associated with detector alarms between the instruments and the control room shall be demonstrated operable at least once per 31 days.

9A.3.6.1.1 Fire Detection for Safety-Related Equipment Class A, supervised fire detection is provided for all areas that contain or present a fire exposure to safety-rel'ated equipment.

9A.3.6.1.2 Fire Detection (NFPA Standards Nos. 72D and 72E)

The fire detection and signaling systems comply with the requirements of NFPA Standards Nos. 72D and 72E, except that position switches for steel-bodied valves indicate the off-normal position when the stem of the valve has moved 2/5 the distance from the normal position. Location and placement of detectors is in accordance with the guidelines of NFPA Standard No. 72E, except where special conditions do not permit. In those cases, detectors are located using criteria developed by registered fire protection engineers, based on engineering judgment, as permitted by NFPA Standard No. 72E. Refer to Section 1.9, Attachment 1.9-61 (Difference 7) for interpretation and specific deviations from NFPA 72E.

These letters are found in the alpha-numeric fine zone designation and are explained in the footnote of Table 9A.3-18.

Nine Mile Point Unit 2 FSAR 9A.3.6.1.3 Testing of Detectors Preoperational and. periodic testing of detectors will not affect the actuation of protective relays in other plant systems. Unit 2 does not use pulsed-line type detectors.

9A.3.6.1.4 Audible and Visual Alarms Fire detection systems give audible and visual annunciation in the control room and local audible alarms, and annunciate at the local panels.

9A.3.6.1.5 Unique Alarms Fire alarms are distinctive and unique from other plant system alarms.

9A.3.6.1.6 Power Supplies for the Fire Detection System The Unit 2 fire detection system is fed through the two stub buses through an automatic transfer switch. The primary source which feeds the two stub buses is the 'unit generator, and the secondary sources include either of the two offsite power sources, or the diesel generators. In case of the loss of the primary source, the transfer switch automatically connects the system to the secondary source. This arrangement satisfies the intent of the requirements of NFPA72D, Section 2220. For further details on the Unit 2 electrical system, refer to Section 8.3.

9A.3.F 1.7 Design Bases for Fire Detection Instrumentation Operability of the, detection instrumentation ensures that adequate warning capability is available for prompt detection of fires and that fire suppression systems that are actuated by fire detectors will discharge extinguishing agent in a timely manner. Prompt detection and suppression of fires will reduce the potential for damage to safety-related equipment and is an integral element in the overall facility fire protection program.

Fire detectors that are used to actuate fire suppression systems represent a more critically important component of a plant's fire protection program than detectors that are installed solely for early fire warning and notification.

Consequently, the minimum number of operable fire detectors must be greater.

The loss of detection capability for fire suppression systems, actuated by fire detectors, represents a significant degradation of fire protection for any area. As a result, the establishment of a fire watch patrol must be initiated at an earlier stage than would be warranted for,the loss of detectors that provide only early fire warning. The establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to operability.

9A.3.6.6 Portable Extinguishers Unit 2 portable extinguishers are in compliance with the requirements of NFPA Standard 10. Adverse effects of portable extinguishing agents have been considered in the placement of extinguishers. Portable fire extinguishers applicable to'the hazard and the guidelines of NFPA Standard 10 will be provided in all areas of the plant. An inspection and maintenance program will be written; performance of same will be fulfilled by the onsite fire department.

9A.3.6.7 Design Bases for Fire Suppression Systems The operability of the fire suppression systems ensures that adequate fire suppession capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The fire suppression system consists of the water system, spray and/or sprinkler systems, C02 systems, Halon systems, and fire hose stations. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

In the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service.

Nhen the inoperable fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

The surveillance requirements provide assurances that the minimum operability requirements of the fire suppression systems are met. An allowance is made for ensuring a sufficient volume of Halon in the Halon storage tanks by verifying the weight or level and pressure of the tanks. Level measurements are made by either a UL or FM approved method.

In the event the fire suppression water system becomes inoperable, immediate corrective measures must be taken because this system provides the major fire suppression capability of the plant.
