Title	Loss of Tone Alert System
Event Description	On Thursday, March 29, 2012, at 2242 EDT, Oswego County notified Nine Mile Point (NMP) via the land line of a loss of the Tone Alert System as of 2105 (EDT). Site Emergency Procedures define a loss of Tone Alert System for greater than one hour as a significant loss of Emergency Communications (EPIP-EPP-30). This impacts the ability to readily notify a portion of the Emergency Planning Zone (EPZ) Population for the NMP and (James A. FitzPatrick) JAF Nuclear Power Plants. This failure meets NRC 8-Hour reporting criteria 10 CFR 50.72(b)(3)(xiii). Compensatory measures were verified to be available should the Prompt Notification System be needed. This consists of utilizing the Hyper-Reach system, which is a reverse 911 feature available from the county 911 center. The County Alert Sirens, which also function as part of the Public Prompt Notification System, remain operable. At 2300 EDT, Nine Mile Point received notification from Oswego County 911 that the Tone Alert System has been restored and is fully functional as of 2245 EDT. The licensee has notified the NRC Resident Inspector. The cause of the loss is still being investigated. * * UPDATE AT 1035 EDT ON 3/30/2012 FROM RYAN HAMILTON TO MARK ABRAMOVITZ * * * At 03:33 [EDT] on 3/30/12, Nine Mile Point was notified by the Oswego County Emergency Management Office (OGEMO) that the Tone Alert System had been out of service for greater than one (1) hour. This condition is considered a significant loss of offsite communication capability and is therefore a 50.72 8-hour non-emergency reportable condition per 10 CFR 50.72(b)(3)(xiii). The Tone Alert System failed at 0211 on 3/30/12 and was subsequently restored to service at 0328 on 3/30/12. This failure was the second such failure in a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. The first failure occurred at 2105 on 3/29/12 and was restored at 2245 on 3/29/12. The first failure was reported to the US Nuclear Regulatory Commission Operations Center at 0059 on 3/30/12. The cause of the Tone Alert System loss is being investigated by the OCEMO. Oswego County reported that the National Weather Service had verified the system was broadcasting as designed at 0540 on 3/30/12. During the time the Tone Alert System was unavailable, the county emergency sirens, the Hyper-Reach system which is a reverse 911 feature available from the county 911 center, and 'Route Alerting' where Local Law Enforcement personnel are able to assist in alerting affected areas of the Emergency Planning Zone were available as alternate mechanisms to provide emergency offsite notifications. The licensee notified the NRC Resident Inspector. Notified the R1DO (Newport).
