SUMMARY
Brunswick No. 2 Brunswick Unit No. 2 operated at a.67.7% capacity factor for the month of Janua ry . The following power changes and shutdowns occurred during the month: January 1: Carryover outage from 79-025. The unit was of f-line 106.4 hours during this report period because of a Plant Modification to the safety relief valves. January 7: The unit was shutdown for 51.9 hours because of leakage on safety relief valve F013K. Total " downtime" was 158.3 hours, resulting in a 78.7% availability factor. For more detailed information on individual outages, see the Unit Shutdowns and Power Reduction Log (Aprendix D) for this month. The unit is scheduled for a refueling outage to begin March 1,1980. 1946 166
