| Title | Rps and Pciv Actuation Due to Loss of Offsite Power |
| Event Description | On October 5, 2012, at 1303 hrs. EDT James A. FitzPatrick Nuclear Power Plant (JAF) experienced a loss of offsite power during its planned refueling outage. This resulted in the Reactor Power System (RPS) receiving a valid actuation of containment isolation valves in more than one system. All control rods were fully inserted when the full scram signal occurred. In addition, the four Emergency Diesel Generators (EDG) started in response loss of power but the EDG 'A' output breaker did not automatically close. Investigations are underway.
The following systems were automatically isolated: - Reaction Water Clean-up (RWCU) - Drywell Floor Drain - Drywell Equipment Drain The following systems were automatically actuated: - 4 Emergency Diesel Generators (EDG) All systems functioned as required except as noted above. JAF remains in Mode 5. In addition, a major loss of Emergency Response communication capability has occurred. Some of the systems not available include: Emergency Notification System (ENS), Health Physics Network (HPN), and commercial phone communication. The licensee has notified the NRC Resident Inspector.
On October 5, 2012, at 2011 hrs. EDT, James A. FitzPatrick Nuclear Power Plant (JAF) restored 345 kv backfeed qualified offsite power line and restored non-vital power. One of the two newly installed 115 kv Reserve Station Transformers experienced a lockout signal for an unknown reason which caused an isolation signal disconnecting offsite power. The Emergency Diesel Generators (EDG) started in order to provide vital power to plant systems. Both 115 kv Reserve Station Transformers have been removed from service and corrective actions are resolving this issue and the failure of the EDG 'A' output breaker to close. The EDGs are in standby. The current state of JAF is normal, Refueling Outage mode 5. In addition, Emergency Notification System (ENS), Health Physics Network (HPN), and commercial phone communication have been restored and verified functional. The Emergency Plan is functional. The NRC Resident Inspector has been informed. Notified R1DO (Trapp). |
