The following information was provided by the licensee via email:
"At 1942 EDT on April 22, 2023, during the Beaver Valley Power Station, Unit No. 2 refueling outage, while performing examinations of the 66 reactor vessel head penetrations, it was determined that one penetration could not be dispositioned as acceptable per ASME Code Section XI. The reactor vessel vent line penetration will require repair prior to returning the vessel head to service. The indication was not through-wall as there was no evidence of leakage based on inspections performed on the top of the reactor vessel head. This event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(A).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified"
