| Title | Turbine Trip Due to Main Transformer Fire |
| Event Description | The following information was provided by the licensee via email:
At 0810 EDT on August 27, 2022, with Unit 2 at 27% power, the operating crew received an annunciator for a Turbine Trip Without Reactor Trip. At 0812 EDT, a report came in from the field of a fire in the north yard due to an "A" Main Transformer upper bushing failure. The station fire brigade was dispatched and offsite assistance was requested. However, at 0842 EDT the fire was put out, prior to needing the offsite assistance. No Emergency Action Level threshold was exceeded for this event. The switchyard is in a normal alignment for providing offsite power to Unit 2. At 1015 EDT, the Virginia Department of Emergency Management (VDEM) was notified of the event. Additionally, a notification to the Virginia Department of Environmental Quality will be made due to approximately 100 gallons of oil reaching the ground. As such, this issue is being reported per 10 CFR 50.72(b)(2)(xi) for "'Any event or situation for which a news release is planned or notification to other government agencies has been or will be made.' The NRC Resident Inspector was notified. |
