Title | Emergency Operations Facility and Emergency Notification System Phone Out of Service |
Event Description | This is a non-emergency notification being made under 10CFR50.72(b)(3)(xiii) due to the potential loss of emergency preparedness capabilities due to the effects of hurricane Isaac.
At approximately 0735, the Emergency Operations Facility (EOF) diesel generator was discovered to be tripped and not available, leaving the primary EOF without AC electrical power and, therefore, unavailable since normal AC power was also lost due to weather conditions. Efforts to repair the EOF diesel generator have been initiated and personnel have verified the Alternate EOF is functional. State, local and federal agencies have been informed of the plan to use the alternate EOF in case of an emergency preparedness activation. With essential personnel being sequestered at the Waterford 3 power block, the critical EOF functions can be performed from the on-site Technical Support Center (TSC), which is housed within the Control Room ventilated envelope. At approximately 0620 CDT, Entergy Operations, Inc. Emergency Preparedness staff discovered that the NRC Emergency Notification Systems (ENS) was not working. NRC Headquarters was notified at approximately 0715 CDT and was given an alternate phone number to contact Waterford 3. The ENS phone had previously been verified functional at approximately 0330 CDT. The NRC Health Physics Network (HPN) telephone line was verified to be functional at 0922 CDT. The licensee notified the NRC Resident Inspector. |
