AGREEMENT STATE REPORT - DOSE LIMIT EXCEEDED FOR GENERAL PUBLIC

The following information was received from the state of Arkansas via email:

"UAMS (University of Arkansas for Medical Sciences) reported to Arkansas Radiation Control Program on May 27, 2022, that three (3) persons (radiation workers), acting under verbal orders, volunteered to be injected as test subjects for the evaluation of two (2) different PET/CT scanners with F-18 FDG.

"As part of an investigation, radiation exposure calculations were performed, and results submitted for review. It has been determined that the limit for public dose as defined in 10 CFR 20.1003 and stated in RH-1208.a., was exceeded.

"Reporting Requirement: Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation RH-1504.a.2.d and 10 CFR Part 20.2203(a)(2)(iv).

"The NRC HOO was notified by email of this discovery on July 5, 2022."

* * * UPDATE ON 2/15/2023 AT 1348 EST FROM ANGELA MINDEN TO KAREN COTTON * * *

"The University of Arkansas for Medical Sciences (UAMS) reported that three radiation workers volunteered to be injected with F-18 FDG (fluorodeoxyglucose) and scanned in order to compare the image quality of an existing and a new PET/CT scanner. The events occurred between 4/13/2022 and 4/15/2022. As part of the investigation, radiation exposure calculations were performed by a contractor of the licensee, and the results were submitted for Arkansas Department of Health review. The activities of F-18 FDG received by the three physicians were 408.85 MBq (11.05 mCi), 392.2 MBq (10.6 mCi), and 403.3 (10.9 mCi). TEDEs of 24.1 mSv (2,410 mrem), 25.1 mSv (2,510 mrem), and 20.1 mSv (2,010 mrem) were received from x-ray and F-18 FDG combined, respectively. The PET-only TEDEs were 6.1 mSv (610 mrem), 5.2 mSv (520 mrem), and 6.3 mSv (630 mrem), respectively. The estimated doses exceed the limits for an individual member of the public and are therefore considered a reportable event under RH-1504.a.2.D. [10 CFR 20.2203(a)(1)(iv)]."

AGREEMENT STATE REPORT - OCCUPATIONAL DOSE LIMIT EXCEEDED

The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:

"The Agency received written correspondence on February 16, 2023, indicating a worker at a Romeoville, IL nuclear pharmacy (Sofie, RML IL-02074-01) received a whole body dose that exceeded the occupational limits in 32 Ill. Adm. Code 340.210. The exposure occurred over the course of 2022 and no adverse health impacts are anticipated. Specifically, the information provided indicates a quality control production associate received 5,090 millirem over the course of 2022, exceeding the occupational limit of 5,000 millirem.

"The licensee has conducted an investigation and believes the cause is related to both a management deficiency and equipment issues. New duties assigned in July of 2022 resulted in increased exposure which was apparently not reviewed and/or assessed at a frequency sufficient to limit occupational dose. Additionally, dose delivery equipment reportedly failed at some point in 2022, resulting in the use of equipment with insufficient shielding. The licensee identified corrective action as more frequent dosimetry exchange, repair of equipment (timeline unspecified) and reassignment of duties.

"This is a reportable incident under 32 Ill. Adm. Code 340.1230 and was reported to NRC the same day (2/16/23). The licensee provided timely notification. In the next week, IEMA inspectors will perform a reactionary inspection to assess the adequacy of the licensee's investigation and corrective action, compliance with Agency regulations and root cause determination."

AGREEMENT STATE REPORT - UNPLANNED CONTAMINATION EVENT

The following information was provided by the Pennsylvania Department of Environmental Protection (Department / DEP) via email:

"On February 16, 2023, the licensee informed the Department of a contamination event involving Cobalt 60. It is reportable as per 10 CFR 30.50(b)(1).

"On February 16, 2023, the licensee received an exclusive use shipment of boxes of equipment from Dresden Nuclear Station. Upon surveying the conveyance after unloading, the licensee found a small area of contamination approximately 2" x 2" in surface area on the bed of the trailer outside of where the boxes were positioned. The licensee isolated the trailer at its facility, decontaminated the area of contamination, resurveyed the trailer, and released it. The licensee informed their client, Dresden Nuclear Station, of the issue. The DEP is currently in contact with the licensee and will update this event as soon as more information is provided.

"The Department will perform a reactive inspection. More information will be provided as received."

EN Revision Text: OFFSITE NOTIFICATION TO STATE AGENCY

The following information was provided by the licensee via fax:

"At 1618 EST on February 20, 2023, North Anna Power Station notified the Virginia Department of Environmental Quality (DEQ) that water discharged into Lake Anna following hydrostatic testing of tanks associated with a new on-site sewage treatment plant had exceeded the project's general permit (VAG83) pH value.

"Hydrostatic test water discharge activities to Lake Anna began on February 20, 2023 at 0900 EST. A pH sample was collected at 0955 EST on February 20, 2023 and determined to have a pH of 9.1 which exceeded the maximum permit pH of 9.0. Discharge ceased after the reading was collected. Approximately 354 gallons were discharged to Lake Anna. A follow-up ambient pH sample result of 7.8 was collected on February 20, 2023 at 1401 EST from Lake Anna in the vicinity of the discharge pipe. No evidence of dead fish, foam, or other negative environmental impacts were observed.

"This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi) for 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site fatality or inadvertent release of radioactively contaminated materials.'"
