OFFSITE NOTIFICATION DUE TO SANITARY SYSTEM DISCHARGE
"At approximately 1008 [EST] on 11/9/16, site personnel discovered a sanitary lift station overflowing in the protected area. The overflow entered a nearby storm drain that discharges into Outfall 13. The estimated release volume is approximately 10 gallons. The release has been stopped. At 1339 an initial notification was made to SCDHEC [South Carolina Department of Health and Environmental Control]. The cause of the overflow is still
under investigation. Functionality of the lift pump has been restored and cleanup is complete.
"The NRC Senior Resident has been notified."

INSUFFICIENT ALARM AUDIBILITY
"On November 9, 2016, at approximately 1115 hours (EST), the speaker system in Buildings 302, 303, and 306 West was identified as non-operational while performing a functional test of the system. This speaker system 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 speakers could adequately provide speaker coverage for all affected areas of these buildings. Special Nuclear Material (SNM) is processed, handled, or stored within the areas where the speaker system failed; these areas require 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 these areas with a resultant increase of postulated doses. Additionally, awareness of a fire event could have been delayed for these same personnel. A series of compensatory actions were taken including implementing a plant-wide stop-movement of SNM, limiting access to the affected areas to essential personnel, and establishing radio communications between the personnel in these areas and the personnel continuously monitoring the alarm station panel.
"On November 9, 2016, at approximately 1725 hours (EST), full compliance was restored by repairing a damaged cable and by successfully performing a speaker system test in the affected areas.
"The licensee notified the NRC Resident Inspector on November 9, 2016."
