NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES PEACH BOTTOM UNITS 2 & 3 AUGUST 1979 Unit 2 A slight load reduction was taken on August 19th due to environmental considerations with respect to river water temperature. On August 24th, load was reduced to approximately 500 MWe to acconrodate a control rod sequence exchange. The Unit was returned to full load via a preconditioning ramp by August 27th. On August 29th, the Unit 2 Emergency Auxiliary Transformer was blocked as a safety measure for other work. When the transformer was returned to service, its breaker tripped on a transformer differential relay action. An investigation proved the problem to be a stand-off insulator on the transformer. Repairs were completed and the transformer was returned to service.

Unit 3 The Unit operated at a maximum electrical load of 970 MWe at the beginning of the month and was reduced to 925 MWe by the end of the month due to the power coast-down that began in July. The 'A' feedwater heater string was removed from service on August i st, due to excessive internal heater leakage. This resulted in a load reduction of 45 MWe. Since the end of cycle coast-down rate is approximately 4 MWe per day, the load reduction, due to the heat cycle loss, was zero by mid August.

On August 19th, the Unit load was reduced due to environmental considerations with respect to river water temperature and to perform MSIV closure time testing.
