October 18, 1974 Mr. Norman C. Moseley, Director Directorate of Regulatory Operations U. S. Atomic Energy Commission Region II - Suite 818 230 Peachtree Street, Northwest Atlanta, Georgia 30303 Re: Oconee Unit 1 Docket No. 50-269
Dear Mr. Moseley:
This letter confirms a telephone conversation between Mr. F. Jape of your staff and Mr. K. S. Canady concerning my letter of October 7, 1974 transmitting Unusual Event Report UE-269/74-5, " Acceptance Criteria Were Not Met During Unit Loss of Electrical Load Test."
The Corrective Action Section stated that a test to permit deter-mination of the specific parameters which prevented achieving the acceptance criteria would be performed prior to Oconee Unit 1 refueling.
Currently, Unit 1 is operating at the 90 percent power level with Group 6 control rods controlling and Gr 2p 7 control rods fully inserted.
Further deboration to achieve a higher power level to perform the diagnostic test is not desirable prior to refueling.
The diagnostic test will be performed on Unit 2 or 3 during the power escalation testing sequence and design changes which are appropriate will be-i implemented on Unit 1.
-The loss of electrical load test will be performed on Unit 1 to verify that it meets the acceptance criteria j
at some future date after refueling.
j Very truly yours,
