SUMMARY

OF OPERATING EXPERIENCE FOR SEPTEMBER 1995 The unit began the month at 49% power. Power was reduced on 9/01/95 and the unit was taken off-line at 0208 on 9/02/95 (the reactor remained critical) for a forced outage to repair a Motor Operated Disconnect in the switchyard.

The unit was back on-1 ine at 1458 on 9/02/95. The unit was re.turned to 100% by 0900 on 9/04/95. On 9/11/95, a broken conductor was discovered between an i sophase bus and the main generator.

A power reduction was initiated from 100% at 1800 and the unit was off-line at 2106 ( the reactor remained cal) for a forced outage to repair the isophase bus. The unit was placed line on 9/13/95 at 0538, and 100% power was reached by 0600 on 9/15/95. The unit operated at 100% for the remainder of the month.
