Event Notification Report for March 02, 2023

AGREEMENT STATE REPORT - LEAKING SOURCE

The following information was provided by the New York State Department of Health via email:

"The New York State Department of Health (NYSDOH) conducted a routine inspection of lnficon, Inc. on March 30, 2023, and were made aware of a Ni-63 (2.4 mCi as of March 2, 2023) source that exceeded the 0.005 microcurie leak testing threshold and is considered leaking. Information on the source is below:

"Make: NRD, LLC
"Model: N1001 (SSDR: NY-0502-S-103-U)
"Serial Number: INF732
"Date of Sample Collection: 3/2/2023
"Leak Test Result: 1.47E-2 microcuries
"Analysis Report Date: 3/7/2023

"In accordance with lnficon's license, this source was obtained for secondary manufacturing and assembly into Micro Argon Ionization Detector (MAID) cells. lnficon detected this leaking source immediately following assembly prior to distribution in accordance with all regulatory requirements and the conditions of their license. Once it was determined that this source was leaking, personnel were notified, and the device was immediately quarantined. lnficon conducted removable contamination surveys around the device in question, however, they do not believe that any personnel or equipment may have been contaminated from this leaking source. Wipe test results are pending to date.

"Following the results of these wipe tests, the facility plans to dispose of this source and equipment. New York State Department of Health is in continued discussion with lnficon regarding next steps for this event.

"New York State Department of Health also contacted NRD, LLC (source manufacturer) to inform them of the leaking source and request an internal investigation to validate that this leaking source is an isolated occurrence. No information from NRD, LLC has been obtained prior to the date of this notification. New York State Department of Health continues to track this event with lnficon and NRD, LLC.

"No further information on the device, source or incident is available at this time. Any updates to this event will be provided as soon as feasible. This incident is tracked under Incident No.1433 by NYSDOH."

OFFSITE NOTIFICATION

The following information was provided by the licensee via email:

"At 1312 CST on March 2, 2023, Browns Ferry Nuclear Plant Units 1, 2, and 3 initiated voluntary communication to the state of Alabama and local officials as part of the Nuclear Energy Institute (NEI) Groundwater Protection Initiative (GPI), after receiving analysis results for leakage from a demineralized water storage tank that contained activity above the GPI voluntary communication threshold. All these results are significantly less than the limits established by the Nuclear Regulatory Commission (NRC) and Environmental Protection Agency (EPA) for effluents from the station. Further samples obtained of the water prior to entering the Tennessee River were less than detectable. The leakage source has been isolated and additional corrective actions are in progress. This condition did not exceed any NRC regulations or reporting criteria. This notification is being made solely as a four-hour, non-emergency notification for a notification of other government agency. This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi). There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

FITNESS-FOR-DUTY REPORT - SUPERVISOR FAILED FITNESS-FOR-DUTY TEST

The following information was provided by the licensee via phone and email:

"A non-licensed supervisor tested positive in accordance with the FFD [fitness-for-duty] testing program. The individual's authorization for site access has been terminated."

The NRC Senior Resident Inspector has been notified.

AGREEMENT STATE REPORT - LOST/ABANDONED SOURCE

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

"On March 2, 2023, staff with the Illinois Emergency Management Agency and Office of Homeland Security responded to a load of scrap metal that tripped portal monitors in Indiana and was returned under DOT SP-IN-IL-23-001.The load of scrap originated at B.L. Duke in Forest View, IL. Within that load, a small unidentified radium-226 source was identified. It was estimated to contain approximately 150 microcuries of activity. On June 14, 2023, the licensing division learned of the recovery and began an investigation into the applicability of reporting requirements. There are no discernable markings or serial/model numbers. Activity estimates (based on dose rate) would place the source at approximately 150 microcuries. Aside from this source having significantly less activity, this appears to be a Ra-226 radiography source from the early 30's/40's. As this source does not appear to be exempt, it is likely byproduct material as a discrete source of radium and subject to specific licensure. Therefore, it is being reported as a lost/missing source. The source has been placed into the Agency's orphan source collection program and will be disposed of as low level radioactive waste."
Illinois report number: IL230015

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.
