LOSS OF EMERGENCY RESPONSE DATA ACQUISITION AND DISPLAY SYSTEM
"On 10/24/2005 at 12:14 hours, Saint Lucie Units 1 & 2 lost both of the computer trains associated with Emergency Response Data Acquisition and Display System (ERDADS). This is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) as a major loss of emergency assessment capability. Other means to monitor critical data exist in each unit. Troubleshooting and restoration work is in progress."
The licensee notified the NRC Resident Inspector.

INOPERABLE START-UP TRANSFORMERS; HIGH SWITCHYARD VOLTAGE DUE TO HURRICANE WILMA
"At 2300 on October 24, 2005, both unit 3 and unit 4 start up transformers were declared inoperable and Tech Spec 3.8.1.1.e action statements were entered. With both units being energized from their respective start-up transformers, the high voltage limit is 241.5kV in accordance with 0-ONOP-004.6, Degraded Switchyard Voltage. System Operations reported switchyard voltage at 243.5 kV and 242.5 kV for unit 3 and unit 4 respectfully. System Operations was requested to lower switchyard voltage to within limits. At 0015 on October 25, 2005, switchyard voltage being lowered to within the switchyard limits and both start-up transformers were declared operable. The high switchyard voltage is due to hurricane Wilma's impact on the Florida service area that has [led] to low system load with cooler weather conditions."
The NRC Resident Inspector has been notified.
