This event is being reported under 10CFR50 … This event is being reported under 10CFR50.72(b)(3)(xiii) for a major loss of offsite emergency response capability.</br>At 2325 Central Daylight Time (CDT) on 8/12/2007, Callaway Plant received a trouble alarm for the Emergency Operations Facility (EOF). Investigation revealed the EOF had lost one phase of incoming rural electric power which is believed to have been caused by a severe thunderstorm in the area. At 0001 CDT on 8/13/2007, the EOF diesel generator was started and aligned to provide power to all building loads. An EOF functionality evaluation was performed for a loss on normal power with the EOF being supplied from the diesel generator and pre-existing degraded air conditioning cooling capacity. The evaluation concluded that the EOF was fully functional.</br>At approximately 1000 CDT on 8/13/2007, maintenance personnel reported to the Control Room that the emergency ventilation system in the EOF was not functional based on the pressurization fans rotating in reverse. Three phase electrical loads at the EOF are incorrectly polarized apparently due to improper terminations at the diesel generator. If an emergency condition occurs during the time repairs are being made, the EOF will be utilized as long as radiological conditions allow. Procedure EIP-ZZ-C0010, EMERGENCY OPERATIONS FACILITY OPERATIONS, section 4.4, directs EOF management to evaluate the need to relocate operations to the Backup Emergency Operations Facility, as required. Affected emergency responders have been notified of facility conditions and a courtesy notification has been made to the State Operations Branch Chief.</br>The licensee has notified the NRC Resident Inspector.</br>* * * UPDATE PROVIDED BY KEITH DUNCAN TO JEFF ROTTON AT 1248 ON 08/14/07 * * *</br>The EOF (Emergency Offsite Facility) rural electric power was restored to the building at 1730 (CDT) on 8/13/2007. At 0059 (CDT) 8/14/2007 the EOF diesel work was completed, restored and retested satisfactorily. Building temperatures were verified to be at 85 deg F and lowering, this is within the 55-95 deg F range for functionality.
