At 1445 on September 8, 2004, while in Mod … At 1445 on September 8, 2004, while in Mode 3 after an unplanned reactor trip during tropical storm Frances, Crystal River Unit 3 experienced a re-actuation of the B-Train of the Emergency Feedwater System. The Emergency Feedwater System had previously actuated during a Loss of Offsite Power experienced during Hurricane Frances and the B-Train actuation had procedurally been bypassed as part of the plant recovery. While In the process of restoring a Main Feedwater Pump to an operating condition, the signal bypassing the B-Train Emergency Feedwater actuation was momentarily removed due to unusual plant conditions present during recovery from the loss of power This resulted in the re-actuation of the B-Train of Emergency Feedwater. This condition is 8-Hour reportable per 10CFR50.72(b)(3)(iv)(B)(6). The re-actuation of the B-Train of Emergency Feedwater did not have a significant impact on plant operation and the associated equipment has been returned to a standby condition.</br>The licensee informed the NRC Resident Inspector.</br>* * * RETRACTION FROM JOHN ADDISON TO BILL HUFFMAN AT 1402 EDT ON 9/30/04 * * *</br>The following information was provided by the licensee via facsimile:</br>At 1823 (hrs.

The Emergency Feedwater System had previously actuated during a Loss of Offsite Power experienced during Hurricane Frances and the B-Train actuation had procedurally been bypassed as part of the plant recovery. While in the process of restoring a Main Feedwater Pump to an operating condition, the signal bypassing the B-Train Emergency Feedwater actuation was momentarily removed due to unusual plant conditions present during recovery from the loss of power. This allowed for a re-actuation of the B-Train of Emergency Feedwater based on a loss of Main Feedwater Pump signal. However, the two Main Feedwater Pumps had not been operating since the loss of offsite power that occurred on 9/6/04. The A-Train Emergency Feedwater System had been operating continuously since the initial actuation on the loss of offsite power and continued to operate during and after the re-actuation of the B-Train. Re-actuation of the B-Train has been determined to be an invalid actuation in accordance with the guidance of NUREG-1022, and therefore EN 41027 is retracted.</br>The licensee has informed the NRC resident inspector.
