| Title | Emergency Planning Zone Siren Malfunction |
| Event Description | The MCR [Main Control Room] at Limerick Generating Station was informed by PEMA [Pennsylvania Emergency Management Agency] that EPZ [Emergency Planning Zone] siren #129 located at Maryland and Western avenues in Chester County was sounding. The siren maintenance contractor was contacted to silence and repair the siren. No plant emergency exists. The siren activation was caused by an equipment malfunction. The remaining sirens in the EPZ remain functional. An 'Event of Potential Public Interest' will be issued for this problem.
The NRC Resident Inspector, the State, and local officials will be notified of the siren malfunction. The state is expected to issue a press release.
The siren was not an EPZ siren but rather a local fire house siren. Therefore, the licensee is retracting this event. Notified the R1DO (Trapp). |
