of I

During normal startup, while conducting F-ST-4E ti tled "HPCI Sub-system Logic Functional Test" to satisfy the requirements of Technical Specifications Appendix A, Table 3-2.2, it was noted that a plug in instrument 02-3-LIS-72A was leaking. The other instruments moni toring the same parameter were veri fied operable (See LER-79-061/03L-0) before any attempt to repai r the leaking plug was made.

Since the other instruments were operable the event did not represent any significant hazard to the public heal th and safety.

In order to repair the instrument it was placed out of service and a jumper was inst.lled to place it in the trip condition until the plug had been removed and the adjustment screw beneath the plug had been tightened and the plug re-placed. This repai r was completed on the same day as the discovery.
