EN Revision Text: AGREEMENT STATE REPORT - LOST GAUGE
The following information was provided by the Texas Department of State Health Services via email:
"On September 4, 2025, the licensee reported that one of its technicians lost a Troxler 3440 moisture/density gauge. The gauge contains a 40 millicurie Am-241 source and a 10 millicurie Cs-137 source. The radiation safety officer (RSO) stated the gauge was being used at a field site.
"The technician needed to go to the bathroom and placed the gauge into its transport case. The technician locked the transport case, placed it into the back of the truck, and put a locking cable through one of the transport case handles. The technician left the area and, when he arrived at the convenience store, he found the tail gate down and the case and gauge missing. The cable that was through the handle was still secured to the truck and through the case handle, but the handle had been pulled off the case. The technician contacted the RSO and informed him that the gauge was missing.
"The RSO stated the technician and a manager had looked for the gauge. They handed out cards with their contact information to the workers at the job site and contacted local law enforcement. The licensee does not believe any individual would receive any significant exposure due to this event.
"Additional information will be provided as it is received in accordance with SA-300."
TX incident #: 10224
TX NMED # TX250042
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 - UNABLE TO RETRACT SOURCE
The following information was provided by the Wisconsin Department of Health Services Radiation Protection Section (the Department) via email:
"On September 23, 2025, the Department received notification that, on the same date, the licensee was unable to retract a radiography source containing approximately 12.5 curies of Ir-192 into the fully shielded position. The licensee could not immediately determine the cause of the event. The QSA 880 Delta radiography camera was secured inside a locked fixed radiography vault, and the boundaries of the restricted area were under continuous surveillance by a radiographer. On September 24, 2025, the licensee was able to successfully retract the source to the fully shielded and secured position. The licensee is [removing] all the associated equipment [from] service and inspecting the equipment to determine cause of the event. The Department will perform an investigation."

AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The following information was summarized from the State of Florida Bureau of Radiation Control (BRC) via email:
On September 24, 2025, BRC received a report from the licensee regarding the loss of control of a moisture density gauge on the same date. The initial report was that the device had been stolen, but subsequent video footage indicated that the issue was loss of control due to failure to secure the gauge for transport in a truck. The gauge and case are missing but locked. The licensee believes the gauge was lost between a job site in North Port, FL, and Sarasota, FL. The incident has been referred to materials and inspection for investigation.
The device is a Instrotek model number 3500 and contains 10 mCi of Cs-137 and 44 mCi of Am-241/Be.

The following is a summary of information provided by the Colorado Department of Public Health and Environment (the Department) via email:
The Department received a notification from the licensee that one (1) exit sign containing 7.62 Ci of tritium was lost in Boulder, Colorado.
Manufacturer: Isolite Corporation
Model Number: 880-12-6
Isotope: H-3
Activity: 7.62 Ci
Event Report ID No.: CO250029
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 - MEDICAL EVENT
The following information was provided by the California Department of Public Health, Radiologic Health Branch (RHB) via email:
"The University of California Los Angeles (UCLA) reported to RHB that a reportable medical event (underdose) had occurred on September 24, 2025. A patient was to receive 200 mCi of Lu-177 Lutathera for a neuroendocrine tumor via an intravenous line and a mechanical infusion pump. However, it was calculated that the patient only received 80 mCi of the intended dose.
"The registered nurse starts the IV (3-way connections), and the patient receives amino acids for the first hour. Next, a certified nuclear medicine technologist (CNMT) connects the syringe of Lutathera and connects it to the pump. It takes 45 minutes to complete the infusion, and the pump increases its pressure over time. Upon returning to remove the syringe and restarting the amino acid drip, the CNMT noticed the IV had leaked onto the chux [pad] and a small part of the patient's arm skin. The medical radiation safety officer (RSO) was notified and reported to the patient's treatment room. The patient's arm was decontaminated, and the medical physicist calculated the patient had approximately 2-4 mCi on their skin (estimated 30-60 rem skin dose). The Lu-177 contaminated chux materials were collected and evaluated by the nuclear medicine department to contain approximately 120 mCi of the leaked dose.
"UCLA's initial investigation indicates that the increasing pressure from the infusion pump allowed the IV connection to become loose and leak. RHB will continue to follow-up with UCLA and receive their full event report."
California 5010 Number: 092425
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

AGREEMENT STATE REPORT - VEHICLE CARRYING NUCLEAR GAUGE INVOLVED IN AN ACCIDENT
The following information was received via email from the Virginia Radiation Materials Program (VRMP):
"At approximately 1020 EDT on September 26, 2025, VRMP was notified of an automobile accident involving a vehicle carrying a portable nuclear gauge. At approximately 0820 EDT on September 26, 2025, a Troxler model 3430 portable nuclear density/moisture gauge (S/N 36802), containing 9 mCi of Cs-137 and 44 mCi of Am-241, was in a vehicle that was struck from behind in Chesterfield, VA. While a relatively minor accident, once it was noted that the radioactive material was present, the Chesterfield Hazardous Material team responded.
"The vehicle was isolated (300-meter perimeter), and the highway was shut down for approximately 2 hours. The authorized user notified his supervisor (assistant radiation safety officer (RSO), who then notified the RSO. The [assistant RSO] went to the site to evaluate the gauge. She notified VRMP. Per the assistant RSO, the gauge was appropriately blocked, braced, and secured in the trunk of the car when it was rear-ended. The car sustained damage but there was no apparent damage to the case or gauge.
"The licensee and the hazmat team surveyed the case/gauge and readings were within acceptable ranges indicating no source exposure. The case/gauge was moved to another of the licensee's vehicles and returned to the licensee's storage facility for further evaluation. There were no injuries as a result of the accident and no radiation exposures.
"VRMP will follow up with an investigation."

AGREEMENT STATE REPORT - LOST SOURCE
The following information was provided by the Florida Bureau of Radiation Control (BRC) via email:
"The radiation safety officer (RSO) with Citrus Cardiology Consultants in Crystal River, Florida, called the BRC this afternoon regarding a lost 94.6 microcurie Ge-68 source, S/N 2509-89. The RSO said the source is used in a BQC Styrofoam pillow for tuning a positron emission tomography (PET) camera. The RSO said an installer for their new PET camera, out of Houston, Texas, used the Ge-68 source with a Styrofoam pillow to tune the new PET and left the source and pillow in their hot lab. The pillow is approximately two feet long and crescent shaped.
"The RSO said nobody associated with the hot lab saw the BQC pillow, the source, or the box it supposedly came in. The installer has reciprocity with Florida. The company is Catalyst MedTech in Houston, Texas."

TWO TRAINS OF ECCS INOPERABLE
The following information was provided by the licensee via phone and email:
"On October 2, 2025, at 1651 CDT, essential cooling water pump '1C' tripped. Essential chiller '1C' and cascading equipment, including emergency core cooling system (ECCS) train '1C,' was declared inoperable.
"Essential chiller '12A' and cascading equipment, including ECCS train '1A,' was concurrently inoperable for ongoing maintenance.
"This condition resulted in an inoperable condition on 2 out of 3 safety trains for the accident mitigating functions, including the train 'A' and train 'C' high head safety injection (SI), low head SI, containment spray, electrical auxiliary building heating ventilation and air conditioning (HVAC), and essential chilled water. All 'B' train safety related equipment remains operable. There was no impact on the health and safety of the public or plant personnel.
"The repair timeline is unknown. We have already entered the configuration risk management program to mitigate additional maintenance induced risk with a risk informed completion time of October 19, 2025, at 1140 CDT. We are limited by TS 3.7.7.C to restore 1 train of control room HVAC by October 5, 2025, at 1651 CDT.
"This condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been notified."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
The 'C' emergency diesel generator is unavailable due to the loss of cooling water. Maintenance on the ECCS train '1A' is partially complete and operators are working to restore the train to an operable status prior to the technical specification deadline. The essential cooling water pump trip was due to a hot spot causing the pump to overheat. The cause of the hot spot is still under investigation.
The following information was provided by the licensee via phone and email:

All 'B' train safety related equipment remains operable. There was no impact on the health and safety of the public or plant personnel.
"The repair timeline is unknown. We have already entered the configuration risk management program to mitigate additional maintenance induced risk with a risk informed completion time of October 19, 2025, at 1140 CDT. We are limited by TS 3.7.7.C to restore 1 train of control room HVAC by October 5, 2025, at 1651 CDT.
"This condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been notified."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
The 'C' emergency diesel generator is unavailable due to the loss of cooling water. Maintenance on the ECCS train '1A' is partially complete and operators are working to restore the train to an operable status prior to the technical specification deadline. The essential cooling water pump trip was due to a hot spot causing the pump to overheat. The cause of the hot spot is still under investigation.
