Frequently, a situation is encountered in which the technical specification setpoints established by the plant safety analysis are judged to be unacceptable from a plant operational standpoint. This report documents the application of the Electric Power Research Institute (EPRI) Reactor Analysis Support Package (RASP) Light Water Reactor (LWR) setpoint analysis guidelines to provide justification for relaxing the high pressure setpoints at the Oyster Creek Nuclear Generation Station. More Specifically, the plant operation's staff determined that it was desirable to provide increased margin for measurement uncertainties in the high pressure instrument and safety valve setpoints. Previous experience had indicated that there was insufficient margin to justify the desired setpoints using conventional deterministic inputs to the safety analysis and plant performance evaluation process. Therefore, it was determined that the RASP LWR setpoint analysis guidelines, which incorporated the use of a statistical combination of uncertainties methodology, would be used to establish an acceptable set of high pressure setpoints. This report documents the results of applying the RASP setpoint analysis guidelines to provide justification for an acceptable set of high pressure setpoints for the Oyster Creek station. 14 refs., 53 figs., 28 tabs.
