SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 0-2 UNIT Ginna Station Unit //I DATE September 12, 1979 COMPLETED BY Andrew E. McNamara TELEPHONE 1-716-546-2700 Ext. 291-205, at Ginna MONTH August, 1979 The Unit remained shutdown until 0700 on 8/4/79, to comply with requirements in NRC IGE Bulletin 79-13.

The Unit maintained ~ 100% Reactor Power Level during the Report Month, with the following exceptions:

On 8/5, during performance of the Turbine Overspeed Trip Test, the Reactor tripped due to loss of condenser vacuum;- causing a Turbine Trip.

On 8/27, the Reactor Power Level was reduced to w97% to perform a periodic test on the Auxiliary Feedwater System Flow.

On 8/31, a Reactor Power Level reduction was initiated due to the Boric Acid Tanks concentration being out of specifications. The Reactor Power Level was restored to 100% when the Boric Acid Tank concentrations were retest/d and found within specifications..

GINNA STATION MAINTENANCE REPORT FOR AUGUST 1979 During August, normal inspection and minor maintenance was performed.

Major safety related maintenance included:

1. Replacement of the starter, batteries, battery cables and lugs on the diesel fire pump after the failed starter damaged these components.

2. An inspection of the diesel fire pump and right angle drive.

3. Installation of a spare limitorque operator on valve 3505, main steam to the turbine driven auxiliary feedwater pump.

4. Installed a spare relief valve in the 1B charging pump to replace 284.

5. Installed a spare pressurizer master controller PC 431K after operator problems were notetl with the existing controller.
