Event Notification Report for June 16, 2022

AGREEMENT STATE REPORT - LOSS OF TWO TRITIUM EXIT SIGNS

The following is a synopsis of information received via E-mail:

Upon inventory inspection, Frenchman Valley discovered that two tritium exit signs that had been in their possession had been replaced. The property was then thoroughly searched twice and the signs were not located. The whereabouts of the signs are unknown and no replacement records were found.

The signs were manufactured by Isolite. Both signs were model SLX60. The serial numbers were 12-01067 and 12-01068 with each sign containing 8 Curies of tritium.

Nebraska Item Number: NE220002


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.

AGREEMENT STATE REPORT - SOURCE DETACHED FROM PORTABLE GAUGE

The following information was received via E-mail:

"During the morning of 6/16/22, a portable gauge user noticed that the tub and the radioactive source were detached from the gauge cable and stuck approximately 5 ft. underground when the user was trying to retrieve the tub and the source back to the gauge. The portable gauge is a CPN model 503, serial number 50543, containing 50 mCi of americium-241:beryllium. The sealed source is not compromised.

"This event occurred in Kersey, Colorado."

PART 21 REPORT - FAILURE OF AN ARNOLD MAGNETICS POWER SUPPLY

The following is a synopsis of information received via facsimile:

On June 16, 2022, vendor Nutherm International, Inc. was informed that a defect caused the failure of Arnold Magnetics power supply PBM-24-106. The unit had been supplied by Nutherm to a nuclear power plant. The unit failed on or before March 15, 2022 during a 24-hour burn in period and was returned to Nutherm which did an inspection and analysis. Nutherm then returned the unit to Arnold Magnetics, the manufacturer, which completed further analysis. The manufacturer determined the unit failed due to the EMI filter assembly not functioning as designed as a result of the manufacturer's assembler not installing no-mex paper and thus not in accordance with manufacturer's procedure. Both the manufacturer and Nutherm have initiated corrective actions to prevent recurrence.

One facility is listed as being affected: TVA - Browns Ferry. Nutherm notified the affected facility on June 17, 2022.

AGREEMENT STATE REPORT - SHIPMENT LOST THEN FOUND

The following was received from the Illinois Emergency Management Agency (IEMA) via email:

"Representatives for Bard Brachytherapy contacted IEMA at close of business on 6/16/22 to report a shipment of I-125 brachytherapy seeds in route from their Carol Stream, IL facility to Tortola in the British Virgin Islands could not be accounted for after a flight change in Miami, FL. The shipment consisted of two overpacks: One containing five boxes with 350 seeds and a cumulative activity of 241 mCi, and one containing four boxes with 385 seeds and a cumulative activity of 265 mCi. The licensee shipped the packages on 6/7/2022 to O'Hare airport where they were received [and] placed on a commercial flight to Miami. After arrival at Miami, the packages missed two different flights scheduled for Tortola. After an inquiry by the licensee, the carrier reported the package could not be immediately accounted for.

"The incident was reported to IEMA shortly before 1600 CDT and then notification was received at 1627 CDT that the packages were located. This matter is considered closed.

"There were no breaches to packages reported and no resulting public exposures. The packages remained incident to transportation and secure.

"Due to the activity involved (A > 1000x the value in Appendix C to 10 CFR Part 20), the loss is immediately reportable under 32 Ill. Adm. Code 340.1210 and 10 CFR 20.2201(a)(1)(i). Unlike missing shipments of lesser activity, a review of SA-300, Appendix A reporting requirements doesn't give the same caveat that the package must still be missing at the time of reporting."

AGREEMENT STATE REPORT - LOST SHIPMENT

The following was received from the California Department of Public Health Radiologic Health Branch (CDPH/RHB ) via email:

"On 06-29-2022, Mistras Group determined that their shipment containing radioactive materials was officially declared lost. This is not a NSTS [(National Source Tracking System)] level source.

"The RSO [(Radiation Safety Officer)] for Mistras Group Inc. notified CDPH/RHB that a QSA source changer, QSA model 650L, No. 201 containing a QSA Global, Inc. iridium-192 source, model A424-9 No. 683G (radioactivity content on 06-29-2022 was 4.5 curies) shipped on 06-16-2022 had not arrived at QSA Global, Burlington, MA in a timely manner. The [Common Carrier] tracking number indicates the package arrived at the [Common Carrier] hub in Memphis, TN on 06-17-2022, but was delayed with an expected delivery on 06-22-2022.

"On 06-20-2022, QSA Global notified Mistras Group that only two of their three shipments had been received.

"On 06-22-2022, the [Common Carrier] reported the package remained delayed.

"On 06-25-2022, a missing Dangerous Goods (DG) investigation was opened to trace the package. DG was provided a picture of the missing package.

"On 06-27-2022, the [Common Carrier] administrator notified Mistras Group that the package was not located in the hub of the [Common Carrier], Memphis, TN.

"On 6-28-2022, the [Common Carrier] DG personnel notified Mistras Group that the package was not found at LAX [(Los Angeles International Airport)]."

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.
