fiONTHLY OPERATING REPR I The following Licensee Event Reports were submitted during the month of-l October. 1992:
~
LUL92-fl2 On September 12, 1992 whileperforminganElectromaticReliefValve(EMRV)
Pressure Sensor surveillance, the "As found" trip setpoints for the high pressure relief function on two EMRVs were above that specified in the Technical Specifications.
The cause of this occurrence is attributed to setpoint repeatability and instrument drift.
The design setpoint repeatability allows the "as-found" value to be within 2.5 psig of the Technical Specification limit.
Previous surveillance records indicate that these instruments frequently undergo additional drift within Technical Specification limits due to changing plant and envi,onmental conditions.
This occurrence is considered to have minimal safety significance as the automatic
?
depressurization function of the EMRVs is not affected by these pressure switches, all five EMRVs would have actuated to relieve pressure, and the Isolation Condenser System and turbine bypass valves were fully operable.- A calculation concludes that all EMRVs could exceed their Technical Specification-setpoints by 10 psig without an adverse effect on plant safety.
The pressure switches-w-, adjusted to actuate within the lechnical.
Specification limit.
A new pressure sensing system is to be installed in accordance with the Oyster Creek Integrated Schedule, which currently specifies the Cych 15 refueling outage for completion of this project.

h Will refueling or resumption of operation thereafter require a Technical-f specification change or other license amendment?
No important licenair) considerations associated with refueling, e.g.,
new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:
1.
General Electric Fuel Assemblies Fuel design -and performance analysis methods have been approved by the NRC.
2.
Exxon Fuel Assemblies - No major changes have been made nor are there any anticipated.
