%.....f SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 24 TO FACILITY OPERATING LICENSE NO. NPF-38 LOUISIANA POWER AND LIGHT COMPANY WATERFORD STEAM ELECTRIC STATION, UNIT 3 DOCKET NO. 50-382
- 1. 0 INTRODUCTION By application dated February 23, 1987, Louisiana Power and Light Company (licensee) requested changes to the Technical Specifications (Appendix A to Facility Operating License No. NPF-38) for Waterford Steam Electric Station, Unit 3.
The proposed changes would revise the description of fire detectors in the component cooling water pump room "A" and implement certain name changes and correct typographical errors for the charcoal filter units.
2.0 DISCUSSION The changes would revise the Technical Specification Table 3.3-11,
" Fire Detection Instruments" to change the two " Function A" (early fire detection and notification only) smoke detectors in the component cooling water (CCW) pump "A" room to " Function B" (actuation of fire suppression systems and early warning and notification).
In addition, the licensee proposed to implement certain name changes and correct typographical errors for t' e charcoal air filter units.
n Presently, Table 3.3-11 indicates the presence of two smoke detectors in the CCW pump A room which provide early warning fire detection and notification but do not actuate fire suppression systems.
As part of the Associated Circuits Analysis modifications implemented during the first refueling outage for Waterford 3, an existing pre-action sprinkler system was extended into this room.
Local control panel modifications allowed the use of existing early warning notification smoke detectors to also provide suppression system actuation.
The proposed change will revise the smoke detector designation from Function A to Function B to reflect the additional detector capability.
The proposed changes to Table 3.3-11 for the charcoal filter units will correct typographical errors in filter train identification numbers and revise room name descriptions to be consistent with Waterford 3 standard usage.

' 3. 0 EVALUATION The limiting conditions for operation for fire detectors that serve dual. function of early fire warning and fire suppression system actuation are more conservative than for the single function of early fire warning.* Consequently, when the licensee implemented the above-described modification, it was necessary to change the characterization of these detectors so as to apply the more restrictive. action statements.
The change is consistent with the Standard Technical Specifications and conforms with staff fire. protection guidelines delineated in Branch Technical Position (BTP) CMEB 9.5-1.
1 The revisions to the description of the fire detectors for the charcoal air filter units are for administrative reasons only and have no safety significance.
The staff, therefore, concludes that the licensee's proposed amendment to the technical specifications pertaining to fire detectors, as de-lineat'ed in the February 23, 1987 submittal, conforms with the standard technical specifications and BTP CMEB 9.5-1 and is acceptable.
4.0 CONTACT WITH STATE OFFICIAL The NRC staff has advised the' Administrator, Nuclear Energy Division, Office of Environmental Affairs, State of Louisiana of the proposed determination of no significant hazards consideration.
No comments were received.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment relates to changes in installation or use of a facility component located within the restricted area.
The staff has determined that the amendment involves no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
6.0 CONCLUSION
Based upon its evaluation of the proposed changes to the Waterford 3 Technical Specifications, the staff has concluded that; there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and such activities will be conducted in compliance'with the Commission's regulations and the issuance of 'the amendment will not be inimical i

' to the common defense and security or to the health and safety of l
the public.
The staff, therefore, concludes that the proposed changes are acceptable, and are hereby incorporated into the I
Waterford 3 Technical Specifications.
