SUMMARY

OF OPERATING EXPERIENCE T

December 1993 The unit began the month at 100% reactor power and 860 MWe.

On 12/4S3, at 0310, the power was reduced for water box cleaning, removal of the Main Generator cooler section and repair of the 16B Feedwater Heater relief valve. The unit was returned to full power on 12/5S3 at 0630.

On 12/7S3 at 1017, a transformer fire at the Waugh Chapel Substation, located 48 miles north of Calvert Cliffs, required a power reduction until repairs could be affected. Power was decreased to approximately 77% reactor power at 1200 on 12/7S3. During the power reduction, maintenance was performed to repair 13A Feedwater Heater relief valve. The unit was returned to full power on 12/8S3 at 2000.

The Unit ended the month at 865 MWe and 100% reactor power.
