AGREEMENT STATE REPORT - LEAKING SOURCE
The information below was provided by the Georgia Department of Natural Resources via email:
"During a routine sealed source inventory check, Cardiac Consultants of Central Georgia, LLC, license GA 1629-1 discovered that one of their Cs-137 vials (S/N 1615-4-2) appeared to display signs of moisture within. This source's current activity is 0.15078 mCi. A wipe test was then performed. Results of the wipe test confirmed that this source was leaking. The area surrounding the source was surveyed and wipe tested as well. No sign of contamination was discovered. The leaking source has been contained and is secured in the licensee's hot lab in an appropriate shielded container. The licensee waits for a hazardous waste disposal quote before properly disposing. This incident occurred on May 11, 2023, and the licensee reported to the State on May 15, 2023. The State is waiting for the licensee to provide a copy of leak test results for the source of concern and confirmation of source disposal."

EN Revision Text: PART 21 - CAP SCREW IMPROPER LENGTH
The following information was provided by the licensee via email:
"This is a non-emergency notification required by 10 CFR 21.21(d)(3)(i). A written notification in accordance with 10 CFR 21.21(d)(3)(ii) will be provided within 30 days. Steam generator emergency feedwater header discharge isolation check valves (XVC01009A-EF, XVC01009B-EF, and XVC01009C-EF) were designed specifically for and supplied to VC Summer Nuclear Station (VCSNS) by Flowserve under purchase order 4500653391 to replace the previous valves in the emergency feedwater system during refueling outage 27. On May 11, 2023, after valve installation, but prior to initial service, the socket head cap screws were identified as being shorter than the required design length. Valve drawings indicate a design length of 1.25" while the socket head cap screws received were 0.875". The correct length cap screws were installed prior to initial service. VCSNS completed a substantial safety hazard evaluation and determined that the improper length of the cap screws constituted a substantial safety hazard. This deviation in cap screw length resulted in a partial engagement of the cap screw to the cylinder rod extension and could potentially affect valve operation.
"The NRC Senior Resident Inspector has been notified."
