PLANNED OUTAGE OF ERFIS, SPDS, ERDS, AND PPC
"On June 17, 2012, at approximately 1400 hours EDT, the Brunswick Nuclear Plant will be restoring the normal power supply configuration to the Emergency Response Facility Information System (ERFIS) uninterruptable power supply electrical bus 'A.' This will result in a temporary loss of the site ERFIS, Safety Parameter Display System (SPDS), Emergency Response Data System (ERDS), and Plant Process Computer (PPC) functions for both Unit 1 and Unit 2. Brunswick Units 1 and 2 had established an alternate power supply to the ERFIS UPS electrical bus 'A' on June 13, 2012 (i.e., EN 48019).
"During the loss of these functions, manual data transfer will be available to the NRC.
"This event is being reported in accordance with 10 CFR 50.72(b)(3)(xiii), for a loss of emergency preparedness capability. A follow-up notification will be made when the ERFIS, SPDS, ERDS, and PPC functions are restored.
"The NRC Resident Inspector has been notified of these actions."
* * * UPDATE FROM STUART BYRD TO PETE SNYDER AT 1757 EDT ON 6/17/12 * * *
Units 1 and 2 ERFIS, SPDS and ERDS have been returned to service. The PPC is expected to be returned to service at approximately 1900 EDT.
The licensee will notify the NRC Resident Inspector. Notified R2DO (Ayers).
