Event Notification Report for February 08, 2023

AGREEMENT STATE REPORT - OVEREXPOSURE TO THE FETUS

The following report was received by the Louisiana Department of Environmental Quality [the Department]:

"On January 31, 2023, University Hospital & Clinics, Inc. notified the Department of a Nuclear Medicine Event. A patient back on October 26, 2022, was being treated with thyroid ablation with isotope I-131 with an activity of 30 mCi. The patient was found out to be pregnant at eleven weeks at the time of treatment. The physicist determined that the fetus received 5 rads."

Louisiana Event Report Number: LA20230001

AGREEMENT STATE REPORT - LIQUID RADIOACTIVE CONTAMINATION

The following information was provided by Utah Department of Environmental Quality, Division of Waste Management [the Division] and Radiation Control, via email:

"On January 31, 2023 at 1600 MST, the Intermountain Heart Institute, Cardiac Molecular Imaging Coordinator reported to the RSO [Radiation Safety Officer] that at 1445 MST a technologist, removing a Rb-82 (rubidium-82) generator from service, found liquid radioactive contamination in the bottom of the well chamber of the Infusion System. A syringe was used to remove the saline from the well of the Infusion System and the liquid was placed in the liquid radioactive liquid waste storage. Decontamination procedures were followed. The Infusion System well was wiped dry with paper towel(s). All radioactive waste was placed in approved radioactive waste storage. Wipe test(s) were performed.

"This incident has no impact on patient treatment. All Quality Control procedures passed while the generator was in use which verifies that patient treatments were within all requirements.

"The manufacturer was contacted for assistance and it is planned that the generator will be shipped back for investigation. We will follow the manufacturer's instructions for the shipment. A new generator has been placed in the Infusion System so that patient care can continue today.

"The Division will investigate this matter and update the record upon completion of the investigation."

AGREEMENT STATE REPORT - STOLEN GAUGE

The following information was provided by the Iowa Department of Public Health (Iowa HHS) via email:

"During the night or early morning of January 31, 2023 - February 1, 2023, a Troxler portable nuclear gauge (model 3430, containing 9 millicuries Cs-137 and 44 millicuries Am-241:Be) was stolen from the truck of a licensee in Shellsburg, Iowa. It was reported that the employee had an early morning nuclear job on the day of February 1, 2023, in which he took the device home. Upon the early morning of February 1, 23, when the employee went to leave for the job, he discovered that the truck had been broken into. Items in the cab and all materials' testing equipment in the bed of the truck had been stolen, including the licensed portable nuclear gauge.

"The cause is still under investigation. Corrective actions will be determined.

"The Licensee notified the local sheriff's office. Iowa HHS will follow-up to support the response and provide assistance as needed and will update this event as they investigate."

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.

EN Revision Text: AGREEMENT STATE REPORT - EXCESSIVE EXPOSURE

The following information was provided by the Louisiana Department of Environmental Quality (LDEQ) via email:

"LDEQ was notified by the Acuren Inspection Radiation Safety Officer (RSO) via the DEQ Radiation Hotline at approximately 1240 EST on February 6, 2023, concerning a possible industrial radiography camera excessive exposure. According to the RSO, at approximately 1025 at the Shell Norco Refinery, a possible excessive exposure occurred. Two radiographers did not crank the Ir-192 source completely back in the camera. The first radiographer had his hand close to where the source was located for approximately 10 seconds. The estimated whole-body exposure for both radiographers is 448 mR and the worst-case exposure to the hand for one of the radiographers is 96.86 R. The licensee is currently doing a reenactment to have a better idea of the potential exposures. The licensee is sending the radiographers for a blood count. The camera is a QSA Global 880 Delta (s/n D13733) with 41 curies of Ir-192 (s/n 54759)."

EN Revision Text: PRIMARY CONTAINMENT DEGRADED

The following information was provided by the licensee via email:

"At 1738 EST on 02/07/2023, while in mode 5 at 0 percent power, it was determined during local leak rate testing (LLRT) that the primary containment leakage rate exceeded the allowable limit defined in 10 CFR 50, Appendix J, 'Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors.' Both primary containment isolation valves in a penetration failed LLRT requirements which represents a failure to maintain primary containment integrity.

"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."
