| event text = On September 16, 2009, at approximately 1036 hours, as a result of a regularly scheduled test of the Indian Point Energy Center (IPEC) Alert Notification System (ANS) 18 of 172 sirens did not pass the test. The sirens were not tested and declared as functional within one hour and in accordance with the reporting guidelines the event is reportable under 10CFR50.72(b)(3)(xiii) as a major loss of offsite response capability (i.e., a loss of 10% or more of the total number of sirens for more than one hour). | | event text = On September 16, 2009, at approximately 1036 hours, as a result of a regularly scheduled test of the Indian Point Energy Center (IPEC) Alert Notification System (ANS) 18 of 172 sirens did not pass the test.

Preliminary investigations and troubleshooting determined 14 sirens failed to indicate via the ANS computer system successful siren activation due to an incorrect software data adjustment for these 14 sirens. ANS technicians corrected the software error for these 14 sirens and are continuing to investigate the cause of the failure of the remaining 4 sirens to activate. To validate that the software error for the 14 sirens was corrected, a functional test of 1 of the 14 sirens was conducted. The test indicated the siren was functional but investigation and troubleshooting is continuing to validate this. | Preliminary investigations and troubleshooting determined 14 sirens failed to indicate via the ANS computer system successful siren activation due to an incorrect software data adjustment for these 14 sirens.
