,%.....J SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO. AMENDMENT NO. 53 TO FACILITY OPERATING LICENSE NO. NPF-38 LOUISIANA POWER AND LIGHT COMPANY WATERF0f:D STEAM ELECTRIC. STATION, UNIT 3 DOCKET.NO. 50-382 1.0 If;TRODUCTION By application dated December 23, 1988 Louisiana Power and Light Company (LP&L or the licensee) requested changes to the Technical Specifications
( Appendix A to Facility Operating License No. NPF-38) for Waterford Steam Electric Station, Ur.it 3.
The proposed changes would correct the terminology cf control room isolation for toxic gas protection action.
2.0 DISCUSSION The Control Room Air Conditionirig System operates in three distinct nevdes :
(1) normal, (2) pressurized to protect against high radiation, and (3) isolated to protect against toxic gas.
In protecting against high-radiation, the system draws air from outside the control room and puses it thrcugh filters to remove the radiation. This allows the control room to be slightly pressurized as air is recirculated and prevents inleakage of radioactivity from other airborne sources. This operation is generally referred to as recirculation.
In the toxic gas protection. n: ode, the outside air cannot be filtered to remove toxic gases and it is necessary to isolate the outside air. The air in the control room is circulated (or recirculated) but isolated from outside sources.
The Waterford 3 Technical Specifications were originally issued requiring the Contrul Room Air Conditioning System to be placed in the " recirculation" mode for both the radiation release and toxic gas modes. The industry has realized a problem of referring to both operations as " recirculating" and has proposed to refer to the toxic gas mode as "isolaticn". We agree with the industry and with the proposed Technical Specification change. The change in terminology does not change an operation or affect any safety or other anelysis for the facility.
It does assist the operators by the distinction and is therefore an improvement to plant safety.

e 3.0 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.
4.0 ENVIRONMENTAL CONSIDERATION
The amendment relates to changes in recordkeeping, reporting, or admini-strative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10). 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.
5.0 CONCLUSION
Based upon its evaluation of the proposed changes to the Waterford 3 Technical Specifications, the staff has concluded that: there is reason-able 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 to the common defense and security or to the health and safety of the public. The staff, therefore, concludes that the proposed changes are acceptable, and are hereby f
incorporated into the Waterford 3 Technical Specifications.
