SUPPORTING AMENDMENT NO.to DPR-38, -47 and -55 DUKE POWER COMPANY OCONEE NUCLEAR STATION DOCKETS NOS. 50-269, 50-270 and 50-287 INTRODUCTION _
27, 1976, Duke Power Company By application for license amendment dated May(the lice These proposed to Facility Operating Licenses DPR-38, DPR-47 and DRP-55.
changes concern the measurement and control of radioactive liqui gaseous effluents from the Oconee Nuclear Station (Units 1, Discussion _
The changes proposed by the licensee were as follows:
The condensate monitor tank and the laundry - hot shower tank were added to the list in Table 4.1-3 of tanks to be sampledO 1.
prior to release of each batch. low activity waste tank and for gross beta and gama activity, Ba-La-140 and I-131 were In place of the gross activity analyses, the license will now perform a gamma isotopic analysis including dissolved deleted.

Gamma isotopic sensitivities for the waste gas decay tanks, vent and Reactor Building Purge in Table 4.1-3 were revised to 2.

4.
The required analytical sensitivities in Table 4.11-3 were revised to be consistent with current guidance to demonstrate that the effluent releases are within the Appendix I design objective annual exposure limits and to reflect the current Oconee radiological sampling program. Sensitivities were added for 9 isotopes that were not previously listed in the Table. The sensitivity for I-131 gnalyses on water samples was increased from 0.5 to 1.5 p Ci/m since this is adequate and reasonable.
Evaluation The proposed changes to the Technical Specifications will provide more definitive information from the radiological monitoring program. We find the proposed changes to be acceptable.
We have determined that the amendment does 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 amendment involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR 551.5(d)(4), that an environmental statement, negative declaration, or environmental impact appraisal need not be prepared in connection with the issuance of this amendment.
Conclusion We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Comis-sion's regulations and the issuance of this amendment will not be inimical to the comon defense and security or to the health and safety of the public.
