SUMMARY
APRIL,1995 Oyster Creek entered April at 100% reactor power. On April 8 and 20, power was reduced by 5% to remove the second stage reheaters from service to perform troubleshooting and maintenance. The plant ended April at full load.
i During April, Oyster Creek generated 457,427 net MWH electric and attained a MDC net capacity factor of 102.8%.
I i
MONTIILY OPERATING REPORT LICENSEE EVENT RELTIRI LER 94-016R1 On September 12, 1994, Local Leak Rate Testing (LLRT) results indicated that Main Steam Isolation Valve NSO4B exceeded the leak rate limit of 12.08 3CFH at 20 psig as specified in the plant Technical Specifications. The leak mte was quantified as 36.91 SCFH at 20 psig.
The cause of this occurrence was attributed to a combination of component installation and wear. The safety significance of this event is considered minimal as the total penetration leakage would have been limited by Main Steam Isolation Valve NS03B in the same steam header. Maintenance was perfonned on the valve to restore seat integrity. The as left local leak rate test, performed prior to stanup, was satisfactory.
