Title	Invalid System Actuation of Emergency Core Cooling System Components
Event Description	This report is being made in accordance with 10 CFR 50.73(a)(1), which states in part, 'in the case of an invalid actuation reported under 10 CFR 50.73(a)(2)(iv), other than the reactor protection system (RPS) when the reactor is critical, the licensee may, at its option, provide a telephone notification to the NRC Operations Center within 60 days after discovery of the event instead of submitting a written LER. On December 14, 2005, at 0616 hours0.00713 days <br />0.171 hours <br />0.00102 weeks <br />2.34388e-4 months <br /> EST, a failure of the left channel load sequencer resulted in an invalid actuation of components associated with the left channel design basis accident (DBA) sequencer. Components in the emergency core cooling system were among the components actuated. Therefore, this event constitutes a partial actuation of the emergency core cooling system, which is reportable under 10 CFR 50.73(a)(2)(iv)(A). All components actuated by the event functioned satisfactorily as would be expected for this equipment failure and operating status of the plant at the time of the event. The licensee notified the NRC Resident Inspector.
