| Title | Lost Radioactive Material in Transit |
| Event Description | The following information was provided by the licensee via phone:
On March 5, 2026, at 1224 CST, River Bend declared a radioactive materials shipment lost after it was supposed to be delivered by February 2, 2026. The last time the shipment was scanned in the tracking system was on February 11, 2026, at the [common carrier] distribution warehouse in Pearl, MS. The device is a digital acquisition unit inside a Pelican case which contains 122 microcuries of Co-60. River Bend plans on notifying the State of Mississippi regarding the lost material. Because the quantity of radioactive material lost exceeds 10 times the quantity specified in appendix C to part 20, this is being reported as a non-emergency loss of licensed material. The NRC Resident Inspector has been notified. 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.
