| Title | Emergency Siren Test Failure |
| Event Description | On November 12, 2003, at approximately 1003 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.816415e-4 months <br />, during an annual emergency preparedness siren test, the five sirens from New Hanover County, NC, did not respond to the signal sent by the New Hanover County Emergency Operations Center (EOC). The sirens were subsequently tested from the Brunswick Nuclear Plant (BNP) Emergency Offsite Facility (EOF) and responded as required. Maintenance activities are in progress to restore New Hanover County EOC siren initiation capability. Initiation capability will be maintained at the BNP EOF until the capability is restored to New Hanover County. Of the remaining 31 sirens tested, 30 successfully passed the annual test and are considered to be operable. The additional failed siren blew a control power fuse during the test and has since been repaired, tested, and returned to operable status. The resident inspector has been notified.
The safety significance of this event is considered to be minimal. Both Units 1 and 2 are operating in Mode 1 under normal parameters. Compensatory measures are in place to ensure the affected sirens will initiate if required. Activities to restore siren initiation capability are in progress.
Repairs and retesting have been completed and, as of 1530 ET 11/12/03, New Hanover County EOC siren initiation capability has been restored. Notified R2DO (J. Pelchat) |
