SUMMARY
JANUARY,1995 Oyster Creek entered January operating at 100% reactor power. On January 27 a power reduction to 75%
was perfonned to remove the A-Feedwater String. The feedwater string was removed from service to perform maintenance on V40085. Full power was reachieved on January 28. On January 31, the plant again reduced power to 75% to remove the B-Feedwater String to repair a leaking feedwater pump seal.
The plant generated 471,880MWh net electric and attained a MDC net capacity factor of 102.5%

MONTIILY OPERATING REPORT LICENSEE EVENT REPORT The following Licensee Event Report was submitted during the month of January,1995:
LER 94-022 On December 19, 1994, while perfonning a reactor startup following the 15R refueling outage, it was noted that the amount of nitrogen being added to the primary containment was higher than nonnal. It was subsequently detennined that leakage from the primary containment exceeded the Technical Specification limits. A reactor shutdown was initiated and an Unusual Event was declared. A subsequent evaluation detennined that the Drywell vent and purge valves were leaking past their seats. The valves were declared inoperable.
The reason for the seat leakage was detennined to be valve actuator misadjustment.
Immediate corrective action was taken to readjust the valve stroke length and perfonn a local i
leak rate test required to declare the valves operable. The reactor shutdown and Unusual Event were tenninated.
The cause of this event was detennined to be failure to comply with existing maintenance administrative procedures. Long term corrective actions are planned which will raise the sensitivity and understanding of maintenance personnel to the need for procedure compliance.
