| Title | Audibility of Alarm System |
| Event Description | A report was made to the facility Corrective Action Program (PIRCS) at 0839 [EST] on 2/21/2014 regarding difficulty hearing plant announcements and alarms in the recently renovated Building 110B restroom. Testing of the Public Address (PA) system confirmed that the PA system was difficult to hear. The speakers associated with the PA system are also used for annunciating the site criticality accident alarm evacuation warning. Subsequent testing of the criticality evacuation alarm indicated the alarm was difficult to hear as well. Safety management personnel were notified of the problem and the restroom was locked and posted with signs indicating the area was not to be occupied, pending resolution of the audibility issue.
The licensee notified the NRC Resident Inspector. |
