| Event Description | The following information was provided by the licensee via phone and email:
At 0911 EST, on 11/17/2025, it was discovered that both trains of the control room emergency ventilation system were simultaneously inoperable due to an unauthorized door breach of a door in the control room envelope; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D). At 0913 EST, the door was closed, and both trains of the control room emergency ventilation system were restored to operable. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. |
