EN Revision Text: AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following information was provided by the Louisiana Radiation Protection Division (LDEQ) via email:
"On September 3, 2025, at approximately 1605 CDT, the radiation safety officer (RSO) for the licensee, Raba Kistner, Inc., notified LDEQ concerning an incident in which a Troxler model 3430 soil moisture density gauge, S/N 28457, was rolled over by a bulldozer. The incident occurred at the University of Louisiana at Lafayette New Iberia Research Center at approximately 1515 CDT. The RSO reported that during a direct transmission density measurement, in which the source was submerged in approximately eight inches of soil, the gauge was run over by the bulldozer. The gauge source rod was tilted in the soil approximately 45 degrees from the normal. It could not be determined if the source rod was bent, and no attempt was made to retract the density source into the safe position. The gauge possessed two sealed sources, an 8 mCi Cs-137 source, S/N 750-2469, and a 40 mCi Am/Be-241 source, S/N 47-25460. Both sources are approximately 28 years old. The gauge operator is currently maintaining an exclusion area of approximately 30 feet in radius about the gauge, which had a housing that was partially broken apart during the rollover. No radiation surveys have yet been performed of the gauge or surrounding area. The gauge manufacturer was contacted at time of reporting. The RSO will notify the LDEQ of incident status changes."

AGREEMENT STATE REPORT - PACKAGE MISSING IN TRANSIT
The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:
"On September 4, 2025, the Agency received a notification from GE Healthcare in Arlington Heights, IL, to advise of a radiopharmaceutical package missing in transit. The package was shipped via [common carrier] on Thursday, August 21, 2025, for delivery to Mayo Clinic of Rochester, MN. The package contained 1 vial of ln-111 Oxyquinoline product calibrated at 1.0 mCi per vial. There has been no indication that the package was damaged or that the contents were separated from its packaging.
"The last tracking information has documented receipt at the [common carrier] Memphis sort facility on Thursday evening August 21, 2025, at 2251 CDT, but after no movement, it is believed this package is lost at the Memphis sort facility. The activity at time of shipment was 4.089 mCi, making it reportable to the NRC within 30 days. Updates will be made as they become available."
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.

EN Revision Text: AGREEMENT STATE REPORT - TRANSPORTED PACKAGE EXCEEDS LIMITS
The following report was received by the Louisiana Department of Environmental Quality (LDEQ) via phone:
On September 8, 2025, LDEQ was notified by QSA Global in Port Allen, LA, that they received a package with readings of 1 R/hr on contact of the external surface of one side of the package. Upon opening the package, it was found to contain two nuclear gauges, both with their shutters in the locked open position. One gauge was laying on its side and was most likely the cause of the 1R/hr reading. The gauges were a Thermo Fisher gauge, model 5202, serial number B3308 (500 mCi Cs-137) and a Kay-Ray gauge, model 7063P, serial number S92L3001 (200 mCi Cs-137).
The package was received from TaTa Steel Limited in Odissa, India and was shipped via [common carrier].
* * * UPDATE ON 09/09/2025 AT 1303 EDT FROM JAMES PATE TO JOSUE RAMIREZ * * *
The following is a summary of information provided by the Louisiana Department of Environmental Quality (LDEQ) via email:
On September 3, 2025, QSA Global, Inc. received a package for disposal from India.
The sources were received from Juda Wet Processing Plant Kendujhar Keonjhar, Orissa, 758034 India.
The update included the transportation path for the shipment within the United States.

AGREEMENT STATE REPORT - LOST SOURCES
The following information was provided by the Illinois Emergency Management Agency (the Agency) via phone and email:
"As a result of an ongoing Agency investigation into unresponsive general licensees, the Agency became aware that two (2) generally licensed gas chromatography devices containing 15 millicuries of Ni-63 are missing.
"Reportedly, on or about February 2023, Morton Grove Pharmaceuticals (Morton Grove, IL) ceased operations and improperly auctioned the two generally licensed devices, along with all other assets.
"The licensee failed to properly transfer or dispose of the devices, two Agilent Technologies model G23974 (s/n U10800 and s/n U12506). Agency inspectors conducted a site investigation on August 27, 2025, and confirmed no lab equipment is on site.
"The quantity of radioactive material involved, while unlikely to be dangerous to the public, is reportable within 30 days to the Agency and the U.S. NRC. Efforts to identify the buyers of the devices through the auction company have been unproductive and, absent additional information, the investigation is closed."

AGREEMENT STATE REPORT - LOST I-125 SEED
The following information was received from the Massachusetts Radiation Control Program (the Agency) via email:
"On August 11, 2025, three radioactive iodine-125 sealed sources (seeds) were removed from a patient receiving a radioactive seed localization procedure. The licensee expected to remove four I-125 seeds, which were placed in the patient on August 8, 2025, but only located three of the seeds.
"The missing seed was not located after extensive surveys of the patient, staff, and all areas where the seed may have been misplaced. The seed has not been located at this time.
"This is a 30-day reporting requirement per [Code of Massachusetts Regulations] 105 CMR 120.281(A)(2), missing licensed radioactive materials in aggregate quantity equal to or greater than 10 times quantity specified in 105 CMR 120.297, Appendix C.

MANUAL REACTOR TRIP
The following information was provided by the licensee via phone and email:
"At 2020 CDT [on 9/14/2025], [Comanche Peak] Unit 2 reactor was manually tripped due to a malfunction of the electro-hydraulic control (EHC) system on the main turbine. All auxiliary feedwater pumps started due to steam generator `Lo-Lo' levels post trip. This event is being reported in accordance with 10 CFR 50.72(b)(2)(iv)(B) for a reactor trip and 10 CFR 50.72(b)(3)(iv)(A) for an actuation of auxiliary feedwater. Unit 2 is being maintained in hot standby (mode 3) in accordance with integrated plant operating procedures. Decay heat is being rejected to the main condenser via the steam dump valves."
The NRC Resident Inspector was notified.
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
Unit 1 was not affected. The cause of the malfunction of EHC is unknown and under investigation. All rods fully inserted upon the reactor being tripped.
