| Title | Loss of All Emergency Sirens for Greater than One Hour |
| Event Description | On September 19, 2006, at approximately 1208 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.59644e-4 months <br />, the Emergency Planning Department in conjunction with the Indian Point Energy Center (IPEC) Information Technology (IT) Department determined that all of the 156 sirens in the IPEC Emergency Planning Zone were unavailable due to an inability to activate the sirens through the siren computer operating system. The siren computer operating system was unavailable due to its Oracle Database not responding to a restart command during a routine bi-weekly reboot and preventive maintenance activity. Actions were initiated to recover the siren computer operating system and at approximately 1310 hours0.0152 days <br />0.364 hours <br />0.00217 weeks <br />4.98455e-4 months <br />, the system was determined to be recovered and a test verified that all 156 sirens could be activated. In accordance with the IPEC reporting procedure, the loss of 16 or more sirens that can not be returned to service in one hour, constitutes a major loss of the offsite notification capability that requires an 8-hour non-emergency notification in accordance with 10 CFR 50.72(b)(3)(xiii). The Emergency plan has route alerting and public radio announcement available as necessary to notify the public during the time the sirens were not capable of being activated. The condition was recorded in the IPEC corrective action program and actions initiated to investigate and correct the condition. The cause of the failure of the Oracle Database not responding is unknown at this time.
The licensee notified the NRC Resident Inspector and the State and Local Emergency Planning organizations. |
