On 01/11/2019 at 0958 EST, the Fermi 2 Act … On 01/11/2019 at 0958 EST, the Fermi 2 Active Seismic Monitoring system was taken out of service for planned maintenance. During the maintenance activity, the Active Seismic Monitoring System failed a planned surveillance test and was not restored to operability within 72 hours. Compensatory measures to provide alternative methods for event classification of a seismic event were implemented in accordance with the Fermi 2 Emergency Plan procedures prior to the start of the planned maintenance outage. The planned outage time to restore operability exceeded 72 hours on January 14th, 2019, at 0958 EST. Repairs have been completed, the Active Seismic Monitoring System has been declared Functional at 1037 EST, January 14th, 2019, and declared Operable at 1109 EST, January 14th, 2019.</br> </br>The loss of the Active Seismic Monitoring System is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR 50.72(b)(3)(xiii).</br>No seismic activity has been felt onsite and the United States Geological Survey (USGS) recorded no seismic activity in the area. </br>The NRC Resident Inspector has been notified.</br>Femi 2 has two seismic monitors, one on the Reactor Pressure Vessel Pedestal and one in the High Pressure Core Injection (HPCI) room. Only the HPCI room monitor was inoperable.Only the HPCI room monitor was inoperable. +
