| Title | Loss of Communication - Federal Telephone System (Fts) |
| Event Description | At 1315 [EDT] on Wednesday March 12, 2014, while performing monthly communications testing, Pilgrim Nuclear Power Station (PNPS) discovered that portions of the Federal Telephone System (FTS) were not functioning as designed. Specifically, the Emergency Notification System (ENS), is not available from the Control Room or Technical Support Center/ Operations Support Center (TSC/OSC) while the Health Physics Network (HPN), the Reactor Safety Counterpart Link (RSCL), and the Protective Measures Counterpart Link (PMCL) are not currently available from the Technical Support Center/ Operations Support Center (TSC/OSC). All four of these systems were confirmed to be available from the Emergency Operations Facility (EOF). The initial investigation has determined that the failure has not impacted the entire FTS, but may have the potential to impair the licensee's ability to communicate in the event of an emergency.
Immediate actions are being taken to restore the system to functional status and applicable plant procedures have been entered to determine any further mitigating actions. Members of the Emergency Response Organization have been notified of the failures and the need to utilize commercial phone lines as a compensatory action. The NRC Operations Center has been contacted and informed of these communication system failures. It cannot be determined at the time of this notification as to when the system will be restored to full functional status. This event had no impact on the health and/or safety of the public. The licensee has notified the NRC Senior Resident Inspector. This notification is conservatively being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss of certain emergency response communication capabilities as provided by the FTS. The NRC Resident Inspector has been notified. The licensee will notify the state.
Federal Telephone System (FTS) communications testing was completed at 1130 EDT on March 14, 2014. The FTS System has been restored to full functional status. The Emergency Response Organization (ERO) has been informed. The licensee has notified the NRC Senior Resident Inspector and the Commonwealth of Massachusetts. Notified R1DO (Ferdas). |
