REACTOR COOLANT SYSTEM (RCS) PRESSURE BOUNDARY DEGRADED
"At 0130 [EDT] on April 24, 2020, during the Beaver Valley Power Station, Unit 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. Penetration 37 will require repair prior to returning the vessel head to service. The indication was not through wall and there was no evidence of leakage based on inspections performed on the top of the reactor vessel head. The examinations were being performed to meet the requirements of 10 CFR 50.55a(g)(6)(ii)(D) and ASME Code Case N-729-4 to find potential flaws/indications before they grow to a size that could potentially jeopardize the structural integrity of the reactor vessel head pressure boundary. 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."

AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER TEST FAILURE
The following was received from the Commonwealth of Virginia via email:
"On April 24, 2020, a licensee reported that the shutter of a fixed gauge used to measure the level of material inside a process vessel was stuck in the open position. This incident was identified on April 24, 2020, during the biennial leak testing of the source. The gauge is a Ronan Engineering Company, device (Model SA-1, serial number SO-VA-7063), and Source (Model SA1-F37, serial number M7451), containing 40 mCi of Cs-137. The report indicated that the impacted site personnel were notified immediately and barriers were erected to prevent access to the gauge area. Based on the report, there was no public exposure or environmental release from this event. The licensee has contacted the manufacturer (Ronan Engineering Company) for further investigation and to fix the problem.
"The Virginia Office of Radiological Health will review the licensee's written report and determine if additional actions are needed to be taken."
