At 1240 EST, on February 14, 2012, power w … At 1240 EST, on February 14, 2012, power was removed to a major portion of the Emergency Response Facility Information System (ERFIS) to perform a planned modification on Power Panel - 8. This work will install a new breaker in PP-8 requiring that the panel be de-energized for the maintenance. The expected duration of ERFIS inoperability is approximately 6 hours. 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. An additional message will be provided when the ERFIS is restored. It should also be noted that during the period of ERFIS inoperability, it is likely that the system could be restored within one hour to support Emergency Response Facility activation. This report is provided to conservatively cover the possibility that restoration within one hour may not be able to be accomplished if facility activation were to occur. The NRC Resident Inspector has been notified.</br>* * * UPDATE FROM KEN BOYD TO DONALD NORWOOD AT 1516 EST ON 12/14/2012 * * *</br>At 1240 EST, on February 14, 2012, the Emergency Response Facility Information System (ERFIS) computer system became inoperable.
