Event Notification Report for October 20, 2023

AGREEMENT STATE REPORT - MISSING RADIOPHARMACEUTICAL PACKAGE SHIPMENT

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

"The Agency was notified October 12, 2023, by GE Healthcare in Arlington Heights, IL to advise that a radiopharmaceutical package was missing [during shipment]. The last known location was a shipping facility in Fort Worth, TX when it was last scanned by shipping personnel on October 10, 2023, at 0035 CDT as 'arrived.' This package does not represent a significant public safety hazard and there is no indication of intentional theft or diversion.

"The 16 cm cubed package was labeled Yellow-II (TI of 0.1), UN2915 and contained a single 10 mL shielded vial. The activity of indium-111 was 1.535 mCi at the time of shipment but has since decayed to approximately 0.6 mCi. It was reportedly offered for shipment on October 9, 2023, for delivery to a customer in Carrollton, Texas on October 10, 2023. Upon failure to arrive, the licensee initiated a search, and after a review of online tracking data and conversations with shipping personnel, GE Healthcare logistics were informed that the shipping facility has initiated a search for the package and that it is currently unaccounted for in their system. The shipping facility's tracking system last showed the package as 'arrived' as of 0035 CDT on October 10, 2023."

Illinois Incident Number: Il230029

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 - STUCK SOURCE
The following information was provided by the Maryland Department of the Environment Radiological Health Program (MDE/RHP) via email:

"On October 11, 2023 at 1558 EDT, the Maryland Department of the Environment Radiological Health Program was contacted via phone from the Radiation Safety Officer (RSO) of Testing Technologies, Inc. (TTI), and reported that a source disconnect had occurred on 10/10/2023, at about 1000 EDT while working at College Park, Maryland. TTI has an active authorization and reciprocity recognition to practice industrial radiography in Maryland with US NRC license (number 45-25007-01). TTI has a Virginia (Maryland reciprocity license number 94-031-01) and an NRC license; and they are also authorized to retrieve sources. The radiography device was QSA Global, Sentinel 880, device serial number D6011, which contains 50 Ci of Ir-192.

"The incident occurred when the TTI radiographer was taking images of a pipe in the well and while cranking back at finishing, the source became stuck at about the half-way position. The radiographer was aware that the source disconnection from the tube had happened and the source was lodged in a 14 feet deep hole. The radiographer later retrieved the source. The radiographer reported the incident to the TTI RSO.

"The RSO reported that there was no exposure to the public. A dose of 40 mrem was received by the radiographer.

"MDE/RHP will finalize a reactive investigation."

AUTOMATIC ACTUATION OF AUXILIARY FEEDWATER SYSTEM

The following information was provided by the licensee via email:

"On October 18, 2023, at 1116 [EDT], with Unit 1 in Mode 5, an automatic actuation of the 1A auxiliary feedwater motor driven pump occurred when an incorrect action resulted in an automatic start signal. This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the auxiliary feedwater system.

"Feedwater is not needed for plant conditions, and the 1A auxiliary feedwater pump did not feed the steam generators. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

AUTOMATIC REACTOR TRIP

The following information was provided by the licensee via email:

"On 10/19/2023, at approximately 1110 [CST], with Unit 1 in mode 1 at 100 percent power, the reactor automatically tripped. All control rods fully inserted into the core following the trip. All safety functions operated as designed. The cause of the trip is being investigated.

"Operations responded and stabilized the plant. Auxiliary feedwater actuated as expected. Decay heat is being removed by the steam generator through the steam generator power operated relief valve. The trip was complex as non-safety related power was lost to both Unit 1 and Unit 2. Unit 1 is currently in mode 3 and on natural recirculation as both reactor coolant pumps are without power. Unit 2 is currently in a refueling outage with all fuel in the spent fuel pool (SFP). SFP cooling was lost for approximately 70 minutes. No impacts to the SFP temperature were observed.

"Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). Due to the actuation of the auxiliary feedwater system following the reactor trip, this event is being reported as a specified system actuation in accordance with the reporting criteria of 10 CFR 50.72(b)(3)(iv)(A). There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

* * * UPDATE ON 10/19/2023 AT 1646 EDT FROM MARTIN CABIRO TO ERNEST WEST * * *

The second paragraph of the original report is amended as follows to correct information regarding the spent fuel pool for Unit 2:

"Unit 2 is currently in a refueling outage with all fuel in the spent fuel pool (SFP). SFP cooling was maintained at all times with one train of SFP cooling. The second train lost power and was restarted approximately 70 minutes [after power was lost]. No impacts to the SFP temperature were observed."

LOSS OF SEISMIC MONITORING CAPABILITY

The following information was provided by the licensee via phone and email:

"Reporting due to loss of emergency preparedness capabilities. Seismic monitoring capability is non-functional due to loss of power. These monitors do not have a credited compensatory measure.

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The NRC Resident Inspector has been notified. The licensee intends to notify state and local officials.
