EN Revision Text: AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER FAILED IN THE OPEN POSITION

The following is a synopsis of an email received the Georgia Radioactive Materials Program (the department):

On March 10, 2022, the department received an email from the licensee's radiation safety officer (RSO), reporting a failed shutter on one of their sealed nuclear sources that occurred during their routine, semi-annual gauge inspection. The gauge contained 5 mCi Cs-137. The licensee performed a surface survey with readings in a 1 ft. radius. The readings ranged from 0.01 mR/hr to 0.1 mR/hr. The licensee also performed a leak test with results still pending. The licensee plans to dispose of the faulty gauge. No one was exposed during this incident.

Georgia Incident Number: 51

EN Revision Text: AGREEMENT STATE REPORT - LOST PACKAGE CONTAINING RADIOACTIVE MATERIAL

The following was received via email from the Massachusetts Radiation Control Program:

"At 1338 EDT today (3/18/2022), QSA Global, Inc. contacted the Radiation Control Program to report a potential missing package containing radioactive material. The package is a QSA Global 880 source changer and overpack containing a single Ir-192 source with an activity of 6.6 curies (assay date 2/15/2022), [serial number] SN: 31468M. The 880 source changer SN is C010.

"The package was shipped via common courier from Acuren Group, Inc. in Edmonton, Canada on February 15, 2022. On March 3, 2022, package was scanned at the common courier terminal in Memphis, TN (last known location). On March 9, 2022, Acuren contacted QSA Global, Inc. in Baton Rouge, Louisiana to inform them that the package could not be located.

"On March 11, 2022, Acuren contacted QSA Global, Inc. in Louisiana and the common courier for a status. The common courier initiated a search on March 11, 2022, that included the common courier main hub in Memphis, TN. The package could not be located.

"At 0930 EDT this morning (3/18/2022), common courier contacted the QSA Global Baton Rouge office and notified them that the package could not be located. At 1206 EDT today (3/18/2022) the Baton Rouge office contacted QSA Global, Inc. in Burlington, MA to notify them of the missing package.

"The Massachusetts Radiation Control Program considers this event as open pending further investigation."

* * * UPDATE AT 1834 EDT ON 03/22/22 FROM TONY CARPENITO TO THOMAS KENDZIA * * *

The following received via email from the Massachusetts Radiation Control Program:

"Upon Agency (Massachusetts Radiation Control Program) discussion with state of Tennessee, who had contacted the common carrier's Dangerous Goods Administration, the carrier reported on March 22, 2022, the package to be located at the carrier's Custom clearance area at its hub in Memphis, TN and the package is not missing."

Notified R1DO (Jackson) and NMSS Events Notification, ILTAB, and CNSNS via email.

THIS MATERIAL EVENT CONTAINS A 'Category 3' LEVEL OF RADIOACTIVE MATERIAL

Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

EN Revision Text: INSTANCES OF UNANALYZED CONDITIONS

The following information was provided by the licensee via email:

"As part of the extent of condition review for EN55770, [Urenco USA] UUSA identified historical instances where construction vehicles may have been allowed near buildings of concern and our process failed to identify if controls needed to be established for the activities planned. The hazards associated with those construction vehicles were not properly analyzed. UUSA failed to properly document and require controls and, during those times, available [Item Relied On For Safety] IROFS appear to be insufficient to meet the performance requirements in [10 CFR] 70.61.

"No unanalyzed vehicles presently exist near buildings of concern. This event has been entered in UUSA's corrective action program as EV 149990. The plant is in a safe configuration."

The licensee notified NRC Region 2 personnel.
