KET NO: 50-269 UNIT: Oconee Unit 1 DATE: 9-15-78 NARRATIVE SUBSULRY MONTH: August, 1978 The month began with Unit 1 operating at near rated power. On August 2 during a weekly simulated turbine trip test PT/290/05, the unit tripped due to a mal-function in the trip mechanism. A reactor trip followed in which the CRD stator on Croup 1 Rod 10 had to be changed out before returning to service.

Shortly after returning to service on August 5, the unit was forced off to repair a crack in the "B" HP heater extraction line near the turbine. The reactor remained critical during this period and the unit was returned to service again on August 6 at 00:03 hrs. After normal xenon hold,near rated power was reached on August 9.

Power was reduced to 80% on August 18 to investigate the indication of an it. core tilt problem. After evaluation of the pcoblem, power was increased and reached near rated power on August 23.

On August 25 control rod 1 on group 7 dropped because of a stator problem and 4

caused a runback in power. Power level of 53% was established and a decision was reached to operate at this level until the refueling outage which is to begin on September 2.
