30-287 UNIT: Oconee Unit 3 DATE:
9-15-78 NARRATIVE SU.T!ARY MONTH: August, 1978 The unit ran at near rated power until a trip on August 8 caused by a power loss to the EHC system pumps when the 3XA (switchgear) MCC tripped.
Power was restored and the unit returned to service the same day and near rated power was reached on August 9.
On August 25 the unit tripped because of flux / flow imbalance experienced during a swing in the feedwater flow. Again the unit was returned to service the same day and af ter reaching.near rated power on August 26, remained at this level the duration of the month.
