MANUAL REACTOR TRIP
The following information was provided by the licensee via email:
"On 10/12/23 at 2127 EDT, with the Unit 1 in Mode 1 at 100% Power, operators identified degrading condenser vacuum and manually tripped the reactor. All control rods inserted as expected. The trip was not complex, and all systems responded normally post-trip. The cause of the degraded condenser vacuum was an unexpected closure of the condenser air ejector regulator. The cause of the air ejector regulator going closed is not fully understood and is being investigated.
"Following the SCRAM, Operators responded and stabilized the plant. Decay heat is being removed by the Main Steam System through the Atmospheric Relief Valves (ARVs) and Auxiliary Feed Water (AFW) systems. Due to the Reactor Protection System (RPS) actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B) and an eight-hour non-emergency notification per 10 CFR 50.72(b)(3)(iv)(A) for a valid specified system actuation.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

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.
