Washington, D. C. 20555 RE: Oconee Unit 1 Docket No. 50-269

Dear Sir:

By letters dated December 1, 1975 and February 27, 1976, proposed amendments to the Oconee Nuclear Station Technical Specifications were requested to assure the operation of Oconee 1, Cycle 3 core within applicable fuel design and performance criteria. As stated in the accompanying report BAW-1427 "0conee Unit 1, Cycle 3 Reload '

Report" the design cycle length was 292 EFPD. NRC approval for operation of Oconee 1, Cycle 3 was granted on March 25, 1976.

As discussed with members of your staff, recent unscheduled outages on the Duke system have made it desirable to increase the fuel cycle length for Cycle 3 to 312 EFPD. The existing technical specification limits have been reviewed and it has been confirmed that they remain valid for this extended cycle length.

Very truly yours,

, % - lD.
