| Title | Local Alarm Horn Was Found to Be Inaudible During Routine Testing |
| Event Description | At approximately 1345 EDT on 4/18/12, during routine testing on an outdoor Criticality Accident Alarm System (CAAS) Data Acquisition Module (DAM #22), the local alarm horn in the Wilmington Field Services Center (WFSC) building #3 inspection records area was found to be inaudible. The cause and extent of the condition is under investigation.
Personnel were removed from the inspection records area until compensatory measures were established. There are no active fissile material operations impacted by this discovery, thus no unsafe condition existed. This event is being reported pursuant to the requirements of 10CFR70.50 (b)(2). The licensee notified the NC Division of Radiation Protection and the New Hanover County Emergency Response Center.
Upon further review, GNF-A has determined that the reported condition (EN 47851) was not required to be reported by the plain letter of the regulation (10 CFR 70.50(b)(2)) and the filing of the report was inconsistent with industry practice. As such, this report is being retracted. GNF-A has entered the condition identified in the course of the monthly tests (i.e., areas where audibility of the CAAS should be enhanced) into its corrective action program and is addressing them accordingly. The licensee will notify NRC Region II (Thomas). Notified R2DO (Shaeffer) and NMSS (Stablein). |
