SUMMARY

South Texas Project Unit-2 began the reporting period operating at full power. On July 9, reactor power was reduced to approximately 87-percent to allow tube leak repairs on feedwater heater 25B. Repairs were completed and the unit was returned to full power on July 12, at 1400.

On July 13, reactor power reduced to approximately 45-percent when Open Loop Auxiliary Cooling Water (OLACW) Pump 21 tripped due to a grounded cable. He loss of OLACW Pump 21 in conjunction with OLACW Pump 23 being out of service for scheduled maintenance left the unit with one of three OLACW pumps operating.

The grounded cable on OLACW Pump 21 was repaired and the unit returned to full power on July 15, at 1100, l
