Subject:

Arkansas Nuclear One-Unit 1 Docket No. 50-313 License No. DPR-51 Proposed Technical Specification gile: 1511.1, 2040)

Gentlemen-The attached proposed Technical Specification Changes are submitted as requested in your letter dated August 22, 1978.

The proposed change to Technical Specification 3.5.5.1 adds several heat / smoke detectors to the existing list of detectors required to be oper-ble.

The proposed change to Technical Specification 3.18 adds two zones to the list of those required to be protected by fire suppression sprinkler systems.

The inclusion of the additional smoke / heat detectors and fire suppression systems in the appropriate tables of the ANO-1 Technical Specifications is an administrative action requested in your letter date? Aug tst 22, 1978.

The inadvertent actuation of any of the proposed systems could not affect safety related equipment. Therefore, we have determined this proposed Technical Specification to constitute a Class II Amendment. In accordance with schedule 170.22 we rave enclosed a check for $1,200.00.

Very.truly yours. 2

3.5.5 Fire Detection Instrumentation Applicability This specification applies to fire detection instrumente aon utilized within fire areas containing safety related equipment or circuitry, for the purposes of protecting that safety related equipment or circuitry.

Obj ective To provide immediate notification of fires in areas where there exists a potential for a fire to disable safety related systems.

Specification 3.5.5.1 A minimum of 50% of the heat / smoke detectors in the locations specified in Table 3.5-5 shall be operable.

3.5.5.2 If less than 50% of the fire detectors in any of the locations designated in Table 3.5-5 are operable, within one hour establish a fire watch patrol to inspect the zone (s) with the inoperable instrument (s) at least once per hour and restore the equipment to operable status within 14 days or prepare and submit a report to the Commission pursuant to Specification 6.12.3.2(b) within the next 30 days outlining the action taken, the cause of the inoperability and the plans and schedule for restoring the instrument (s)to operable status.

Bases The various detectors provide alarms that notify the operators of the existence of a fire in its early stages thus providing early initiation of fire protection. The detectors in the main and auxiliary control rooms also provide automatic fire protection initiation.

The detectors required to be operable in the various areas represent 1/2 of those installed.

Operability of the fire detection instrumentatic nsures that operable warning capability is available for the prompt detection of fires. This capability is required in order to detect and locate fires in their early stages. Prompt detection of fires will reduce the potential for damage to safety related eq ipment.

In the event that a portion of the fire detection instrumentation is inoperable, the establishment of frequent fire patrols in the affected areas (s) is required to provide detection capability until the inoperable instrumentation is restored to operability.

3.18 Fire Suppression Sprinkler Systems Applicability _

This specification applies to the following fire suppression sprinkler systems protecting safety-related areas:

a. Each of the four reactor building cabic penetration areas.

b. Each of the four cable penetration rooms.

c. Each of the two emergency diesel generator rooms.

d. Cable spreading room.

c. Each of the two diesel generator fuel vaults.

f. Itallway-El 372. (Zone 98-J)

g. Condensate demineralizer area.

Objective To assure that fire suppression is available to safety-related equipment located in the above-listed areas.

Specification 3.18.1 The above-listed sprinkler systems shall be operable at all times.

3.18.2 With one or more of the above-listed sprinkler systems inoperable, establish a continuous fire watch (or operabic smoke and/or heat detection equipment with control ream alarm) or backup fire suppression equipment for the applicabic area (s'; within one hour. Restore the system (s) to operabic status within 14 days or prepare and submit a Report to the Commission pursuant to Specification 6.12.3.2(b) within the next 30 days outlining the action taken, the cause of the inoperability and the plans and schedule for restoring the system (s) to operabic status.

Bases Safety related equipment located in various areas is protected by sprinkler systems. The operability of these systems ensures that adequate fire suppression capability is available to confine and extinguish a fire occurring in the applicable areas. In the event a system is inoperable, alternate backup fire fighting equipment or operable detection equipment is required to be made available until the inoperable equipment is restored to service.
