| Title | Division 3 Diesel Generator Inoperable |
| Event Description | The following information was provided by the licensee via phone and email:
At 1158 EST on 11/26/24, the Division 3 diesel generator was declared inoperable due to failure of the right bank air start motor during a planned monthly surveillance run. Troubleshooting of the issue is in progress. This condition could prevent the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). All other emergency core cooling systems were operable during this time. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: The Division 3 diesel generator supports high pressure core spray, a single train system. |
