A MONTHLY OPERATING REPORT MARCH 198f,
'The following Licensee Event Report was submitted during the month'of
- March 1988:
LER 88-004 - ISOLATION CONDENSER ACTUATION PRESSURE SENSORS EXCEED SETPOINT LIMIT During routine surveillance testing, the Isolation Condenser automatic actuation pressure sensors RE15B, RE15C, and RE15D tripped at values greater than those specified in Technical Specification 2.3.E.
The sensors were adjusted to trip within the desired setpoint limits. This event had no effect upon public health or safety.
The installed sensors have a desi ned accuracy of + 7.5 psig, and have a 8
history of setpoint drift. An analog trip system has been selected as the I
most appropriate way to minimize setpoint drift and improve setpoint repeatability. The sensors being considered for the analog system will' have l
an accuracy that will significantly improve setpoint repeatability. The l
analog trip system is planned to be installed in accordance with the Integrated-Living Schedule.

bO.VfHLY OPERATING REPORT - blARCH 1988 s
JMj C..:N: :
At. the beginning of the report period, Oyster Creek was operating at
. approximately 666 bWe.
Brief ' power reductions were required during the month to perform turbine valve testing.
On March 3, three (3) spurious half-scram signals were received from a reactor high pressure. scram sensor due to vibration.. Reactor pressure was reduced to 1000 psig to increase the margin to the scram setpoint.
On March 9, power was reduced to 628 hWe to replace generator brushes on a reactor recirculation pump.
On March 10, power was further reduced to replace a main steam line flow transmitter, power supply and square root converter.
Following completion of repairs, the reactor recirculation pump was returned to service and power was increased to mr.ximtn generator
- load, t
On March 18, a brace was installed on the instrument rack in the area of the reactor high pressure scram sensor to dampen vibration.
Reactor pressure was increased and maintained at 1010 psig.
On March 21, power was briefly reduced to approximately 633 bWe to I
perform a reactor cleanup system valve in-service test and backwash and precoat a cleanup system filter.
Maximum generator load was maintained for the balance of the report period with an average gross generat6r~1oad of 664 hWe.
