| Title | Tone Alert System Failure |
| Event Description | Vermont Yankee Control Room was notified by E-Plan personnel at 1638 [EDT] that the tone test initiated by the National Weather Service from Albany, NY, failed to activate tone alert radios via the Ames Hill NOAA transmitter and would be out for greater than one hour. At 1712 [EDT] the tone alert radios were functionally tested from the backup transmitter link (WTSA Radio Studio) satisfactorily verifying the ability to activate tone alert radios is available.
The licensee suspects a phone service change was not sufficiently tested. The licensee notified the NRC Resident Inspector.
On 6/13/13 at 1045 EDT, the Ames Hill transmitter was returned to service after restoration of the transmission link between Ames Hill and the National Weather Service. The licensee notified the NRC Resident Inspector. Notified R1DO (Dentel). |
