CRITICALITY ACCIDENT ALARM SYSTEM SPEAKER FAILURE
"At approximately 1320 [EDT] one speaker in the Low Enriched Uranium (LEU) area was identified as not operating when a series of Public Address (PA) announcements were made. Strobe lights, however, were functioning in the area. At 1430 compensatory measures were established to limit access in the affected area to only those personnel with radio communication with the alarm room. At 1600 the system was tested and it was confirmed that the Criticality Accident Alarm System (CAAS) was not audible in the LEU area. No other areas were effected. On August 13, 2019 at approximately 1726, full compliance was restored when the speaker was replaced and satisfactorily retested. The most recent audibility test of this area had been satisfactorily performed on August 6, 2019 at approximately 1100. The licensee notified the NRC Resident Inspector on August 13, 2019 at approximately 1653."
