SUMMARY

OF OPERATING EXPERIENCE DOCKET NO.

50-244 UNIT Ginna_ Station, Unit #1 DATE July 19, 1984 COMPLETED BY d h-Andrew E.

McNdmara TELEPHONE 1 (315) 524-4446 EXT. 301 at Ginna MONTH June 1984 The unit was returned to service on June 2, 1984 after repairs were effected on the turbine generator exciter cooler.

Repairs are detailed on Page 3 of this report.

The reactor power level was escalated to ~ 87% on June 3; on that date a power reduction was initiated to ~ 50% power for inspection of the "B" Condenser for suspected tube plugging problems.

The power level was gradually increased on 6/5 to ~ 90% and full 100% power level was not reached until 6/8 due to heater drain tank problems.

The reactor power level remained at 100% until 6/15 when it was reduced to ~ 98% to perform periodin tests on the Auxiliary Feedwater System.

On 6/27 the reactor power level was reduced to ~ 90% power level due to a turbine runback initiated by a dropped rod signal which proved erroneous.

On 6/28 the reactor power level was reduced ~ 80% due to a loss of condenser vacuum.
