Title	77 Out of 108 Prompt Notification System Sirens Failed Their Monthly Test
Event Description	On August 1, 2007, at 1200 Eastern Daylight time the prompt notification system (PNS) monthly test was performed and 77 of the 108 PNS sirens were not responsive to the test. This is considered to be a major loss of offsite response capability. Testing is being performed to ensure operability of the PNS sirens, trouble shooting has not identified the current problem with the system. 34 of the 77 sirens have been successfully tested and testing of the remaining sirens is being conducted. State, Local and the NRC Resident Inspector have been notified of this by the licensee.
