Andrew E.
McNbmara 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 the previously transmitted report.
The reactor power level was escalated to ~ 87% on June 3; on that date a power _ reduction was initiated to ~ 50% power for inspectionHof 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 periodic 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, caused by an I/C technician pulling control power fuses instead of the instrument. power fuses required by his_ procedure.
Immediate reinstatement of the fuses stopped the rod drop signal before total runback was achieved.
