Title	Failure of Warning Horns
Event Description	At 0500 on 11/09/06, during a routine monthly test of the Criticality Warning System (CWS), a segment of the system covering the Dry Conversion Process (DCP) was found to have no functioning evacuation horns. Appropriate personnel were notified, the DCP processes were shut down, DCP personnel evacuated, and the area cordoned off. The activation of the evacuation horns in the balance of the plant were fully functional. A follow-up test was immediately scheduled for 0900. The building was evacuated and the emergency organization assembled in accordance with normal procedures. During this test, the DCP horns again failed to function. The Emergency Director determined that the processes stay shut down and all personnel remain out of the area while investigations and testing were conducted. The problem was located in the interface between the Data Acquisition Modules (DAM's) and the Auto-Call system that initiates the alarm signals. After a repair was completed, a re-test was completed which confirmed functionality of the DCP process area horns. Current plans are to resume normal operations beginning with the 1500 (evening) shift. This event is being reported within 24-hours pursuant to 10CFR70.50(b)(2) as a safety equipment failure. The licensee will notify NRC Region II.
