AGREEMENT STATE REPORT - LOST SHIPMENT OF I-125 SEEDS
The following was received from the Florida Bureau of Radiation Control (BRC) via email:
"[The licensee] called the BRC at around 0945 EDT to report that a package [containing 53.91 mCi of I-125] of Brachytherapy seeds was lost by [the common carrier]. The package left the manufacturing facility, then the local facility, was picked up by [the common carrier] at 1706 on July 20, 2020, but was lost somewhere before Tampa. IsoAid checked the delivery status on July 21, 2020, but it was not scanned. Route intended to be Tampa to Memphis to New York to South Africa.
"There are 100 seeds loaded in 7 magazines, 6 magazines contain 15 seeds each, and a 7th magazine contains 10 seeds. These seven magazines are contained in a white leaded pig. The pig was packaged in a white box, 9" x 7" x 5" weighing about 4lbs. The package was labeled as Radioactive White - I, UN2915."
Florida Incident Number: FL20-085
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.

60-DAY OPTIONAL TELEPHONIC NOTIFICATION FOR TWO INVALID CONTAINMENT VENTILATION ISOLATION ACTUATIONS
"This 60-day telephone notification is being submitted in accordance with paragraphs 10 CFR 50.73(a)(1) and 50.73(a)(2)(iv)(A) to report two invalid Containment Ventilation Isolation (CVI) actuations at Watts Bar Nuclear Plant (WBN) Unit 1.
"On July 23, 2020, at 0956 Eastern Daylight Time (EDT), the Train A CVI actuated due to an invalid high radiation signal from 1-RM-90-130, Containment Purge Air Exhaust Monitor. Upon investigation, the high radiation signal was caused by a failed power supply. Corrective action included replacing the power supply, 1-RM-90-130 detector, and restoring the system to service.
"On August 7, 2020, at 2017 EDT, the Train A CVI actuated due to an invalid high radiation signal from 1-RM-90-130, Containment Purge Air Exhaust Monitor. Upon investigation, a small tear was identified in the foil covering the scintillation detector. This defect caused erratic indication and the system actuation. The foil was replaced and the system was restored to service.
"Prior to and following the invalid high radiation alarms, all radiation monitors except 1-RM-90-130 were stable at their normal values; therefore, the CVI was invalid. Control room operators performed appropriate checks and confirmed that all required automatic actuations occurred as designed. These events were entered into the corrective action program as CR 1625135 and CR 1628904.
"The NRC Resident Inspector was notified."
