LOSS OF EMERGENCY RESPONSE FACILITY INFORMATION SYSTEM
"At 0543 hours EST, on January 30, 2007, the Emergency Response Facility Information System (ERFIS) computer system became inoperable due to multiplexer (MUX) failure. At this point, it appears that the malfunction is due to a failure of the MUX power supply. Technical support personnel are currently working to restore ERFIS functionality.
"The ERFIS computer system provides monitoring and communications capability for plant data systems including the Emergency Response Data System (ERDS), Safety Parameter Display System (SPDS), Meteorological Data link system, and the Inadequate Core Cooling Monitor (ICCM). The loss of ERFIS requires alternate methods, as described in plant procedures, to be used for the above described functions. Therefore, it is expected that appropriate assessment of plant conditions, notifications, and communications could still be made, if required, during the time that the ERFIS computer system is inoperable. This report is being made in accordance with 10 CFR 50.72(b)(3)(xiii), which is any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability. As previously stated, alternate means remain available to assess plant conditions, make notifications, and accomplish required communications, as necessary.
"An update to this message will be provided when the ERFIS is restored."
The licensee notified the NRC Resident Inspector.
* * * UPDATE ON 01/30/07 AT 1729 EST BY HENRY CURRY TO MACKINNON * * *
ERFIS returned to service at 1700 EST. R2DO (M. Ernstes) notified.
The NRC Resident Inspector will be notified of this update by the licensee.
