UNITED STATES NUCLEAR REGULATORY COMMISSION 7590-01 DOCKETS NOS. 50-269, 50-270 AND 50-287 DUKE POWER COMPANY NOTICE OF ISSUANCE OF AMENDMENTS TO FACILITY OPERATING LICENSES The U. S. Nuclear Regulatory Commission (the Commission) has issued Amendments Nos.
85, 85, and 82 to Facility Operating Licenses Nos. DPR-38, DPR-47, and DPR-55, respectively, issued to Duke Power Company (the licensee), which revised the Station's common Technical Specifications for operation of the Oconee Nuclear Station, Units Nos. 1, 2 and 3, located in Oconee County, South Carolina. These amendments are effective as of the date of issuance.
These amendments revise the Technical Specifications for Unit No. 2 by extending on a temporary basis the allowable period of inoperability of the "2B" High Pressure Injection Pump through August 15, 1980. This action was due to a potential power shortage in the Duke Power Company service area.
The application for the amendments complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's rules and regulations. The Commission has made appropriate findings as required by the Act and the Commission's rules and regulations in 10 CFR Chapter I, which are set forth in the license amendments. Prior public notice of these amendments was not required since the amendments do not involve a significant hazards consideration.
The Commission has determined that the issuance of these amendments will not result in any significant environmental impact and that pursuant to 10 CFR §51.5(d)(4) an environmental impact statement, or negative declaration and environmental impact appraisal need not be prepared in connection with issuance of these amendments.

-2 Otherwise, only one :HPI pump, assuming single failure of the remaining pump, would be required. With Pump "A" operating and Pump "C" on standby, it is required that valve HP-26 which is normally closed, open on receipt of an engineered'safeguards (ES) signal. To reduce the probability of this valve failing to open on signal, an operator would be stationed to ensure the valve does open on receipt of an ES signal.
We have verified with the U. S. Department of Energy, the cognizant Federal agency concerned with adequacy of electrical power availability, that the Duke Power Company service area and the VACAR subregion of the Southeastern power distribution region has practically no electrical energy reserves when con sumption is at the expected peaks in the time period to August 15, 1980.
As the request is only for a duration of 15 days, and conditioned to power needs, the low probability of the most limiting small break (0.04 to 0.10 sq.
ft.), and-the compensating factor of stationing an operator to verify the opening"of valve HP-26, we conclude that this temporary TS change is acceptable.
Environmental Consideration We have determined that the amendments do not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendments involve an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR 951.5(d)(4),
that an environmental impact statement, or negative declaration and environ mental impact appraisal need not be prepared in connection with the issuance of these amendments.
Conclusion We have concluded, based on the considerations discussed above, that: (1) because the amendments do not involve a significant increase in the probability or consequences of accidents previously considered and do not involve a signi ficant decrease in a safety margin., the amendments do not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be conducted in compliance with the Commission's regulations and the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
