SUMMARY
OF OPERATING EXPERIENCE August 1995 s
De unit began the month at 55% (410 Mwe) due to the abnormally high circulating water temperatures (heat sink).
A functional evaluation was performed on the Service Water System and associated components. It was determined that operation at full power could be sustained, with specific limitations concerning available components and maximum circulating water temperature. Power reached 100% at 1035 on 08/04/95.
A power reduction commenced at 0855 on 08/17/95 due to a saltwater leak on a waterbox drain line.
Power was reduced to 92% while repairs were made. Commenced increasing power at 1505 and power was restored to 100% at 1625 on 08/17/95.
A planned power reduction to 70%, to clean waterboxes and perform maintenance on the Steam Generator Feed Pump Control System, commenced at 2150 on 08/18/95. Power remained at 70% until 1045 on 08/20/95 and was restored to 100% at 2200.
On 08/23/95 at 2029 power was immediately reduced to 87% due to a control element assembly (CEA) being dropped during the performance of surveillance testing. He CEA was restored to the correct position and power was retumed to 100% on 08/24/95 at 0600.
The unit continued to operate at 100% power for the remainder of the month.
