Re: Oconee Nuclear Station +I;-pi/. ,

Docket Nos. 50-269, -270, -287

Dear Mr. Giambusso:

Oconee Nuclear Station Technical Specification 1.6.1, " Quadrant Power Tilt," currently requires the use of the out-of-core power range detectors to determine the core power tilt. As you are aware, the Oconee reactors have both an out-of-core and an in-core system for measurement of core power. The requirement to preferentially use only one system to measure quadrant power tilt can unnecessarily restrict station operation. Therefore, pursuant to 10 CFR 50.90, a revision to Oconee Technical Specificaticus 1.6 and 3.5.4 which will provide added flexibility to the measurement of quadrant power tilt, is requested. The proposed revisions are indicated on the attached replacement pages.

Very truly yours, uf -
