LOCAL ALARM HORN WAS FOUND TO BE INAUDIBLE DURING ROUTINE TESTING

"At approximately 1315 EST on 3/7/12, it was discovered during routine testing on an outdoor Criticality Accident Alarm System (CAAS) Data Acquisition Module (DAM #21), that the local alarm horn in the Wilmington Field Services Center (WFSC) building #1 in-vessel tooling refurbishment area was inaudible. The cause of the condition is under investigation.

"Personnel were removed from the in-vessel tooling refurbishment area until compensatory measures were established. There are not active fissile material operations impacted by this discovery, thus no unsafe condition existed.

The licensee notified the NC Division of Radiation Protection and New Hanover County.
