TWO CRITICALITY ALARM HORNS FAILED TO SOUND DURING TESTING
"At 1030 on 2-2-01 the PSS was informed that the two Criticality Accident Alarm System (CAAS) pneumatic horns for building C-337-A failed to sound properly during testing. The system is required to be operable according to TSR 2.4.4.3.b for the prescribed modes of operation. Even though the system was declared inoperable at the time of the failure it is possible that the system would not have performed its intended safety function had it been required prior to being declared inoperable. The two horns were replaced and satisfactorily tested.
"This event is reportable under 10 CFR 76.120(c)(2) as an event in which equipment required by the TSR is disabled or fails to function as designed."
The NRC resident inspector has been informed of this event.
