On August 17, 2016 at approximately 1739 h … On August 17, 2016 at approximately 1739 hours (EDT), one speaker in Building 120 was identified as non-operational while performing a functional test of the system. This speaker is designed to annunciate alarms generated from the Criticality Accident Alarm System (CAAS) required by 10CFR70.24, alarms generated from the Fire Alarm Control Panel, and Public Address System announcements. Additional functional testing identified that no redundant speaker could adequately provide speaker coverage for all affected areas of this building. Special Nuclear Materials are not processed, handled, or stored within the area where the speaker failed; however, this area requires evacuation in the unlikely event of a nuclear criticality accident as described in the NFS Emergency Plan. There were no actual radiological or other nuclear safety consequences. The potential consequence was that in the event of a nuclear criticality accident, evacuation could have been delayed for those personnel within Building 120 with a resultant increase of postulated doses. A series of compensatory actions were taken to restore compliance including installation of a temporary speaker and limiting equipment operation to limit background noise. On August 18, 2016, at approximately 1100 hours (EDT), full compliance was restored as demonstrated by successfully performing a speaker test in the affected area.</br>The licensee notified the NRC Resident Inspector on August 18, 2016.NRC Resident Inspector on August 18, 2016. +
