DESCRIPTION OF SUPPLEMENTAL CHANGES TO PROPOSED CHANGE NO. 200 TO THE TECHNICAL SPECIFICATIONS PROVISIONAL OPERATING LICENSE NO. DPR-13 The following is a supplemental request to revise Section 3.14, "Fire Protection System Operability," and Section 4.15, "Fire Protection Systems Surveillance," of the Appendix A, Technical Specifications for San Onofre Nuclear Generating Station, Unit 1 (SONGS 1).
Description of the Supplemental Change This supplemental request deletes the fire protection reporting requirement from Section 3.14, "Fire Protection System Operability," to limit the reporting of the fire protection deficiencies to those which meet the criteria specified in 10 CFR 50.72 and 10 CFR 50.73. This is consistent with the guidelines in Generic Letter 86-10, "Implementation of Fire Protection Requirements," issued April 24, 1986.
The Specifications 3.0.3 and 3.0.4 exemptions as existed prior to the issuance of Generic Letter 87-09 are retained in this supplement in accordance with the comments from the NRC staff.
In addition, editorial changes are provided in Section 3.14.1 and the Basis of Section 4.15.6 for clarification.
Existing Technical Specifications See Attachment 1.
Proposed Technical Specifications See Attachment 2.
Significant Hazards consideration Analysis The supplemental change deletes the special reporting requirements from Section 3.14, "Fire Protection System Operability," limiting, therefore, the reporting of the fire protection system deficiencies to those which meet criteria in 10 CFR 50.72 and 10 CFR 50.73. This is consistent with the guidelines in Generic Letter 86-10, "Implementation of Fire Protection Requirements."
However, the requirement to submit a Special Report to the Commission pursuant to Specification 6.9.2 is retained for situations in which a fire watch patrol cannot be restored within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> because of radiological or life-threatening safety hazards. The Specifications 3.0.3 and 3.0.4 exemptions as existed prior to the issuance of Generic Letter 87-09 are retained in this supplement in accordance with the comments from the NRC staff since an amendment has not been issued which affects these sections.
In addition, revisions are provided in Section 3.14.1, "Fire Suppression Water System," to emphasize the requirement for at least one Unit 1 pump and in the Basis of Section 4.15.6, "Fire Detection Instrumentation," to clarify the channel test criteria in accordance with the comments from the staff.
This supplemental request is strictly administrative in nature and, therefore,is bounded by the analysis provided in Amendment Application No. 167 submitted by letter dated March 20, 1989.
Safety and Significant Hazards Consideration Determinations Based on the Safety Evaluation provided in Amendment Application No. 167, it is concluded that:
(1) the supplemental changes to Proposed Change No. 200 do not involve a significant hazards consideration defined by 10 CFR 50.92; and (2) there is reasonable assurance that the health and the safety of the public will not be endangered by the proposed supplemental change.

5/30/Se
- 3. The Fire Hose Stations With one or more of the fire hose stations indicated in Table 3.14.1 inoperable, route an additional equivalent capacity fire hose to the unprotected area from an operable hose station within one hour. The provisions of Specifications 3.0.3 and 3.0.4 are not 93 applicable.
5/30/8
- 4. The Fire Detection Instrumentation With one or more of the fire detection instruments shown in Table 3.14.2 inoperable.

Restore the inoperable instrument(s) to operable status within fourteen days, or in lieu of any other report required by Specification 6.9, prepare and submit a Special Report to the Commission pursuant to Technical Specification 37 6.9.3.c within the next thirty days outlining the course of action taken, the cause of the inoperability and the plans and schedule for restoring the instrument(s) to operable status.
- c. The provisions of Specifications 3.0.3 and 3.0.4 93 are not applicable.
5/30/8 The operability of the Fire Suppression Systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related equipment is located. The Fire Suppression Systems consist of the water system, spray and/or sprinklers, and fire hose stations. The collective capability of the fire suppression system 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 affected equipment is restored to service.
In the event that the fire suppression water system becomes inoperable, immediate corrective measures must be taken since this system provides major fire suppression capability of the plant. The requirement for a twenty-four hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measure to provide adequate fire suppression capability for the continued protection of the nuclear plant.
3-101 Revised: 6/17/86
The operability of the fire detection instrumentation ensures that adequate 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 40 damage to safety related equipment and is an integral 3/8/78 element in the overall facility fire protection program.
In the event that a portion of the fire detection instrumentation is inoperable, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is returned to service.
