DOCKET: 50-269 UNIT: Oconee 1 DATE: 11/15/85 NARRATIVE

SUMMARY

Month: October, 1985 Oconee Unit 1 began the month at 100% power. On 10/02, the unit ran back to 90%

power because of a faulty cable on the Integrated Control System. The unit returned to 100% that afternoon. On 10/07, the unit was forced off-line by a Steam Generator tube leak. The unit returned to service on 10/18. The 1D1 and

. 1El Heater Drain pumps and 1B Feedwater pumps had mechanical problems following the outage which were overcome after startup. The unit operated at-100% during the balance of the month.

SUMMARY

Month: October, 1985

- Oconee Unit 3 began the month in refueling, returning to service on 10/08. The unit was at 100% by 10/11 following Physics Testing. The unit was forced to reduce power to 85% during the morning of 10/14 due to Secondary Chemistry I

restrictions and was forced off line that afternoon due to leakage from the Reactor Coolant system. The unit returned to service on 10/24. The unit operated at 100% for the rest of the month.
