Title | Ens Phone Lines Out of Service Due to a Failed Rectifier |
Event Description | At 1740 CST the control room was notified by a commercial phone provider that they had received alarms indicating the ENS communications lines were out of service. Attempts to use the ENS lines confirmed that the ENS system is not functioning at the site. Commercial lines with an 899 prefix are also not functioning. Alternate commercial lines are available and have been verified functional. The vendor has determined that the loss of the ENS lines are the result of a failed rectifier. It is currently not known when the ENS lines will be returned to service. Farley Nuclear Plant may be contacted via commercial line.
The licensee will notify the NRC Resident Inspector.
ENS line at Farley was repaired and successfully tested. The licensee will notify the NRC Resident Inspector. Notified R2DO (Henson) |
