The following information was provided by the Kentucky Department for Public Health & Safety, Radiation Health Branch (KY RHB) via email:
"KY RHB was notified by the Radiation Safety Officer (RSO) at Arkema via voicemail and email on 8/30/2022 at 1501 EDT, that on August 30, 2022, one fixed gauging device (Ronan Engineering SA1-F37, Serial Number M8107), containing 5 Ci of Cs-137 (source Serial Number not reported, assay date 08/1991) had developed a problem in that that the shutter arm was not moving freely to the closed position. The technician eventually moved the shutter arm to the closed position and verified radiation levels to be normal. The gauge is mounted on a tank, manned entry is currently restricted, and plant personnel have been notified that there is no access allowed to the vessel. No overexposures were reported due to the malfunction. All operational and maintenance activities related to the vessel will be delayed until the manufacturer (Ronan Engineering) repairs the shutter mechanism. The licensee has contacted the manufacturer/service provider to remediate this situation."

AGREEMENT STATE REPORT - LOST Y-90 MICROSPHERES
The following information was received from the Wisconsin Department of Health Services (the Department) via email:
"On August 31, 2022, the licensee notified the Department that they had lost control of licensed radioactive material. Per the licensee's report, on or about August 10, 2022, four sharps containers with yttrium-90 microsphere waste were inadvertently taken from the licensee's decay-in-storage room and placed in a locked room in the hospital's shipping department for disposal as biohazardous material. On August 15, 2022, the four sharps containers (approximately 60 millicuries of yttrium-90) were picked up by the hospital's biohazardous waste vendor, where they are assumed to have been autoclaved and disposed in a landfill. The licensee became aware of the loss on August 29, 2022. Based on the current activity of the sources (less than 1 millicurie) no attempt will be made to retrieve the material. No members of the public are expected to exceed public dose limits. A Department investigation is ongoing."
WI incident no.: WI220020
THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - LOST I-125 BRACHYTHERAPY SEEDS
The following information was provided by Illinois Emergency Management Agency, Radioactive Materials Branch (the Agency) via email:
"The Agency received a partial report via email from the licensee on September 1, 2022, indicating the potential loss of two brachytherapy seeds, accounting for a maximum estimated activity of 1.05 millicuries. The licensee has conducted an investigation and although the package appeared undamaged; believes the seeds may have been lost in transit from Atlanta Medical Center in Atlanta, GA. Requests for clarification and the nuclide (either I-125 or Pd-103) have not yet been returned. The amount and form of radioactivity would not be useful for illicit intent and there is no indication of intentional theft or diversion. While incomplete, this incident has the potential to be reportable and will be communicated to the United States Nuclear Regulatory Commission Headquarters Operations Officers today.
"On August 8, 2022, Bard Brachytherapy received a package from the Atlanta Medical Center. The package contained sources that were outside of the primary container and were lodged in the packaging foam. The shipping box looked undamaged from the outside, but three of the four primary containers were loose or open inside. The licensee counted the sources in the package and found 28. The return sticker included in the box from Atlanta Medical Center listed that 30 sources should have been returned. Surveys were conducted of the packaging material, the receiving and returns processing areas, and the path between to verify that the unaccounted-for sources were not in the Illinois facility. The counts were verified with the shipper and the licensee confirms two brachytherapy seeds (likely I-125) were most likely lost in transit."

INVALID SYSTEM ACTUATION
The following information was provided by the licensee via fax:
"Auxiliary Feedwater Pump #12 actuation and isolation of the Steam Generator Blowdown for 'A', 'B' and 'C' Steam Generators.
"Per 10 CFR 50.73(a)(1), the telephone notification is made under 10 CFR 50.73(a)(2)(iv)(A) for an invalid actuation. On 7/28/2022 at 1705 CDT, the Unit 1 Control Room received alarm SPQD0183 'SG LO-LO LVL TRN B ACT' and actuation of the Auxiliary Feedwater Pump #12 and isolation of the Steam Generator Blowdown for 'A', 'B' and 'D' Steam Generators. This event was classified as an unplanned entry into Technical Specification Shutdown LCO equal to or less than 24 hours 'Simple Restoration', due to the availability of CRMP.
"This alarm occurred several times and with each occurrence the alarm was short lived (1 second or less). Operations placed Auxiliary Feedwater Pump #12 in the Pull-To-Lock position to prevent starting of the pump with each alarm occurrence. During troubleshooting it was determined that SSPS Logic 'R' train was generating the intermittent alarm condition. A Logic board and a Safeguard Driver board were replaced which was identified as the possible cause. Operations performed applicable sections of the Logic test to ensure SSPS 'R' train operable.
"The event had no effects/consequences on the unit. The Logic board and Safeguard Driver board in SSPS 'R' train were both replaced as the possible causes, and therefore both boards were sent to Westinghouse to determine which board was at fault."
The NRC Resident Inspector has been notified.
