The following information was provided by … The following information was provided by the licensee via phone and email:</br>This 60-day optional telephone notification is being made in lieu of a licensee event report submittal as allowed by 10 CFR 50.73(a)(1). This notification is made pursuant to the reporting requirements specified in 10 CFR 50.73(a)(2)(iv)(A) for an invalid actuation of one of the systems listed in 10 CFR 50.73(a)(2)(iv)(B). </br>At approximately 1705 EST on December 5, 2024, an invalid actuation of emergency diesel generator (EDG) '2' occurred. It was determined that the run timing relay failed causing energization of the starting air solenoid valves ultimately resulting in EDG '2' spuriously starting and running with no demand and no auto-start signals.</br>The actuation was not initiated in response to actual plant conditions, it was not an intentional manual initiation, and there were no parameters satisfying the requirements for initiation of the system. Therefore, this event has been determined to be an invalid actuation.</br>During this event, the actuation of EDG '2' was complete. Initiation of attendant instrumentation/controls and supporting auxiliary equipment was as expected for the actuation being outside normal EDG start logic. Emergency bus 'E2' remained energized from offsite power and EDG '2' did not tie to bus 'E2'. </br>This event did not result in any adverse impact to the health and safety of the public.</br>The NRC Resident Inspector has been notified.
