SUMMARY

OF OPERATING EXPERIENCE DOCKET NO.0-2 UNIT Ginna Station Unit b'1 DATE COMPLETED BY LEWIS DEP MONTH A ril 1979 TELEPHONE 1-716-546-2700 Ext.291-205, at Ginna Low power physics testing were completed and unit was placed on the line on April 3.Turbine tests and physics testing were completed as power was escalated.

At 98%power, the condensate bypass valve opened, power was reduced to 92%.The low condensate pressure was due to the"A" condensate pump still undergoing annual overhaul and the discharge valve of the"B" condensate pump was not in the full open position due to a faulty position indicator.

On,Apiil 11, a relay on the main transformer fan coolers failed, load reduction was started and terminated when the fan coolers were reinstalled.

Operation at 92%continued due to condensate pump maintenance.

'4 s 0 GINNA STATION MAINTENANCE REPORT FOR APRIL, 1979 During April, normal inspection and minor maintenance was performed.

Major safety related maintenance included: 1.Replacement of a faulty bistable on Overpressure Protection Channel 452.2.Replacement of a bad batch board on Boric Acid Flow Channel 110.3.Replacement of a damaged valve diaphragm on the containment radiogas/particulate monitor pump return to containment.

4.Repair to the flow control valve FCV llOA for the normal flow path from the Boric Acid Tanks to the Reactor Coolant System.5.Replacement of a leaking 3 1/2" long piece of pipe adjacent to FCV llOA.In addition, the check valve next to this piece of pipe was also replaced as a preventive measure.
