SUMMARY
OF OPERATING EXPERIENCE 1995 i The following is a summary of Grand Gulf Nuclear Station (GGNS) Unit 1 operating !
l experience for the 1995 calendar year. During 1995, the reactor was critical for 7,039.9 ;
hours with the generator on line for 6,832.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.
On 3/16/95, a reactor scram occurred caused by a pinched-wire ground fault in RCIC minimum flow valve E51F019 and intermittent ground of backup scram valve C11F110A which energized during Division il surveillance (half scram existing). Immediate corrective l actions included reworking the ground on the RCIC valve and replacing the backup scram valve solenoid. Also the conduit going to the solenoid was sealed to prevent moisture i intrusion. (JC) [LER 95-004] - Curation hours - 37.3 l
l On 4/15/95, the reactor was shut down for Refueling Outage # 7. This outage was extended due to generator stator leak repairs. Duration hours - 1377.1 1
On 6/11/95, the reactor was manually scrammed to replace Reactor Recirculation Pump "A"
- 1 Seal. Duration time - 68.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. l l
On 6/14/95, the reactor was manually scrammed to replace Reactor Recirculation Pump "A" '
- 1 Seal due to second failure. Duration hours - 140.7 1
On 6/20/95, the reactor was taken off grid for L 'rbine overspeed test. Duration time - 6.8 l hours l A reactor scram occurred on 7/3/95. The scram was caused by a trip of Main Turbine and l Reactor Feedwater Pumps resulting from an invalid reactor-water-level-high trip signal i during surveillance of channel "B" (JC) [LER 95-007) - Duration hours - 37.7 On 7/12/95, a reactor scram was caused by a Main Turbine trip on low condenser vacuum resulting from failure of an HP condenser expansion joint. (SG) (LER 95-008) - Duration l hours 139.9 1 1 ;
i On 7/30/95, a reactor scram occurred due to failura of a current transformer on 500 kV generator output breaker J5228. (JC) [LER 95-010) - Duration hours 68.4 1
On 9/17/95, the reactor scrammed at low reactor water level caused by failure of the pump discharge check valve to close following a trip of Reactor Feed Pump Turbine "B" resulting from malfunction of pressure regulating valve PRV-4 in lube oil system. Both "B" and "A" discharge check valves were repaired to prevent a similar occurrence. (SJ) [LER 95-011)-

l FAILED FUEL INDICATIONS / INSPECTIONS - 1995 Failed fuel assessments performed during Cycle 8 indicate a single, medium-sized l fuel failure exists in the Grand Gulf core. '
The failure occurred on 9/9/95. Fuel Reliability Index peaked at 3061 Ci/sec and leveled at about 1000 Ci/sec.
l The failure appears to be in a second cycle bundle in core cell location 32-27. This cell contains two second cycle bundles. Current plans are to discharge both of l
these bundles during RFO8 (October 1996).
