SUMMARY
Month:
October 1986 McGuire Unit i began the month at 100% power. A string of feedwater heaters were out of service which caused a reduction in efficiency. The heaters were placed back in service on 10/05 and the efficiency increased. The unit remained at 1007. until 10/15 when load was reduced to 97%. A computer point was not returned to service following testing. The problem was corrected and the unit returned to 100% within an hour. The unit remained at 100%
until 10/21 when a run back to 55% power occurred. The run back was caused by a burned contact on a relay. -The unit returned to 100% that evening. On 10/29, the unit was forced off line by a safety question concerning Rotork valves. The unit remained off line for the rest of the month.
