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.

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.

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."

"At 1605 EST on 11/12/21, it was determined that the RCS Pressure Boundary does not meet ASME Section XI, Table IWB-341 0-1, 'Acceptable Standards' due to a through wall leak of the Core Exit Thermocouple Nozzle Assembly.
"Measures have been taken to establish Mode 5 for corrective actions.
"This event is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(A).
"The NRC Resident Inspector has been notified.

The following information was provided by the licensee via email:
"On 11/12/2021 EN 55574 reported possible evidence of pressure boundary through-wall leakage observed on a Core Exit Thermocouple (CET) tube. On 3/10/2022, based on laboratory analysis of the affected CET tube section, FPL Engineering determined that there was no pressure boundary through-wall leakage associated with this event. Analysis identified that the leakage likely originated from an adjacent threaded compression fitting on a tubing joint. This condition complies with ASME Section XI requirements and is therefore not reportable. This follow-up NRCOC notification is a retraction of EN 55574."

EN Revision Text: LOST SOURCE
The following information was provided by the licensee via phone and email:
"Agilent Technologies manufacturers ECDs [Electron Capture Detectors], containing 15 millicuries each, of Ni-63 for use in Gas Chromatographs (for generation of ionized atmospheres for chemical analysis). We have a number of ECDs in use at our facility as addressed below for customer support and R&D. We are required by our license to perform wipe (swipe) tests every six months. The ECD in question was last wiped in August. We were in the process of performing our most recent wipe test last month (February) when we discovered the ECD and its host GC were no longer in the lab they were being used in. [Source was determined to be missing on February 22, 2022 at 1000 EDT when it could not be found for the scheduled swipe test.] We discovered quickly that the individual chemist with ownership of the ECD retired in November of 2021 [last date the device was accounted for]. Investigations to date have not been successful in recovering the ECD. Information pertinent to the incident to follow. I will also be submitting a letter to the appropriate address in one month if we are still unable to recover the ECD."
"ECD Model # G2397A
ECD Serial Number # U25487
Activity: 15 millicurie Ni-63
Facility security: Access to building is limited to those issued electronic badges. Labs are further secured by electronic access only to necessary personnel. [Therefore the source is not suspected to have been stolen.]"
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.

The following information was provided by the California Department of Public Health (RHB) via email:
"On March 22, 2022, at approximately 0834 PDT, the ARSO/Field Operations Manager of Southern California Geotechnical contacted RHB Brea concerning the moisture/density gauge, CPN, MC-1DR, serial number MD 20400784, (Cs-137 0.370 GBq, Am-241, 1.85 GBq) that had been found missing along with the Authorized User since 3/18/2022 when he was last seen at a jobsite at 1740 Mountain Avenue, Norco, CA and did not report for work on Monday, March 21, 2022. [ARSO/Field Operations Manager] has contacted emergency contacts of the Authorized User and the employment agency he was hired through with no response at this time. [ARSO/Field Operations Manager] has also notified Orange County Sheriff and filed a missing person's/stolen property report, reference number 22-009329. A copy of the theft report will be forwarded to the RHB Brea office to be included as part of this report. [ARSO/Field Operations Manager] will contact local newspapers to attempt to retrieve the stolen radioactive gauge as well as notifying local servicing vendors of radioactive gauges to be alert for the serial number of the stolen gauge in case it turns up for service. The investigation will continue to determine if the radioactive gauge and the Authorized User can be found. This is being reported to the NRC Operations Center as a 24-hour report under 10CFR30.50(b)(2) since the radioactive gauge has been lost and it can not be determined what condition the sources are currently in."
