EN Revision Text: AGREEMENT STATE REPORT - RADIOPHARMACEUTICAL LOST IN TRANSIT

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

"The Agency was notified by Medi-Physics, Inc., doing business as GE Healthcare on the afternoon of 11/3/2022, that a radiopharmaceutical package containing 1.5 millicuries of In-111 was reported as lost while in the care of a common carrier. This does not represent a significant public safety hazard and there is no indication of intentional theft or diversion. Details on the package and shipment are provided below. The Georgia program will be notified along with the US NRC Operations Center.

"The package was shipped on 10/28/2022, from the licensee's facility in Arlington Heights, Illinois to Jubilant Radiopharma in Macon, Georgia. The package made it to the common carrier hub. Thereafter, it could not be accounted for and was declared lost on 11/3/2022. The package activity was 1.5 millicurie at the time of shipment but has decayed to approximately 1.147 millicurie at this time.

"IL Item Number: IL220042"

* * * UPDATE ON 12/5/22 AT 1339 EST FROM GARY FORSEE TO ADAM KOZIOL * * *

"No changes in status of the package have been provided by the carrier. The package has now decayed to under 1.0 microcuries of In-111. This matter is considered closed."

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 - STOLEN MOISTURE DENSITY GUAGES

The following information was provided by the Colorado Department of Public Health and Environment (the Department) via email:

"At approximately 0715 MST on November 28, 2022, the Department was contacted by the [Company Radiation Safety Officer] CRSO of Kleinfelder, Inc. (CO 958-01) to inform the Department that two Troxler 3430 (SN 35349 & SN 35335) moisture density gauges were discovered to be stolen from their temporary job site. Each gauge had sealed sources containing not more than 9 mCi of Cs-137 and 44 mCi of Am-241:Be or 66 micro curies of Cf-252. An authorized user arrived at the temporary job site around 0530 MST to pick up supplies when they noticed the door to the container express (conex) box was open. Upon further investigation, it was discovered that both gauges were missing. The site was secured by a security fence and under video surveillance, and that footage is currently under review. The thieves broke the exterior lock to the conex box door and they broke a lock to a job box in the conex box that contained both gauges in their locked transport cases. The job box was also bolted to the ground but those bolts were left intact. The CRSO estimates that the gauges were last seen/used on November 23rd or 24th, but the date of the theft is unclear at this time. Additionally, multiple other contracted companies were targeted in this theft that presumably occurred during the Thanksgiving holiday weekend."

AGREEMENT STATE - STUCK SHUTTER

The following report was received via email from the Texas Department of State Health Services [the Agency]:

"On November 28, 2022, the licensee notified the Agency that it had discovered that the shutter on one of its Ohmart-Vega SH-F1A gauges had been stuck in the closed position since November 23, 2022. The gauge had been closed and locked out on November 22nd for work on the vessel. On November 23rd the gauge was placed back into service. Over the holiday weekend the unit operations had continued to get high readings which would indicate a buildup in the system or a closed shutter. On November 28th the gauge was checked. The licensee's radiation safety officer found the two bolts on the shutter handle were sheared and the shutter was in the fully closed position. No exposures have resulted from this event. An investigation is ongoing. Source: Cesium-137, 5 millicuries, SN: OV-0050 (this SN serves also as the gauge source holder SN). More information will be provided as it is obtained in accordance with SA-300."

Texas Incident Number: I-9966

AGREEMENT STATE REPORT - LOST EXIT SIGNS

The following information was provided by the Colorado Department of Public Health and Environment via email:

The licensee discovered two tritium exit signs were lost. The exit signs are Isolite Corporation model 2040-60G-20BK signs containing 23 Ci of tritium (H-3) each. This is being reported under Colorado Regulations Section 4.51.1.1 (10 CFR 20.2202(a)(1)(i)).

UNPLANNED CONTAMINATION

The following information was provided by the licensee via email:

"The plant is in a safe configuration.

"On December 4, 2022 at 0901 MST, water was discovered on the floor of the Liquid Effluent Collection and Transfer System (LECTS) room. A pump had catastrophically failed and resulted in leakage of 170 L of contaminated water from slab tank 3 to the inside of the slab tank berm. Upon arrival of the technician, the pump was stopped and the leak was isolated. Some of the water, estimated to be 10 L, leaked out of the berm. Access to this area was restricted at approximately 1100 MST by roping the area off and posting as a contaminated area. Dose rate readings in the area were taken and found to be less than 1 mr/hr and had not increased from previous surveys performed prior to the spill. Urenco USA (UUSA) expects the area will remain posted until after 1100 MST on December, 5, 2022, therefore the reporting requirement in 10 CFR 70.50(b)(1) will be met. The spill is in the process of being cleaned up.

"This issue has been entered in UUSA's corrective action program as EV 158739."
