UNANALYZED CONDITION
The following information was provided by the licensee via phone email:
"On September 4, 2025, at 1110 EDT, it was determined that the units are in an unanalyzed condition. A review of DC control circuit protection schemes identified circuits which are uncoordinated due to inadequate fuse sizing. This results in a concern that postulated fire damage in one area could cause a short circuit without adequate protection, leading to the unavailability of equipment credited for 10 CFR 50 Appendix R safe shutdown. This condition is not bounded by existing design and licensing documents; however, it poses no impact to the health and safety of the public or plant personnel. Therefore, this event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(B).
"Compensatory actions for affected fire areas have been implemented.
"The NRC Senior Resident Inspector has been notified."

SECONDARY CONTAINMENT HATCH LEFT UNSECURED
The following information was provided by the licensee via phone and email:
"On September 4, 2025, at 0855 CDT, Grand Gulf Nuclear Station operators discovered the enclosure building roof hatch was unsecured and open approximately 1 inch. This resulted in inoperability of secondary containment.
Following discovery, the hatch was immediately closed and latched. Secondary containment operability was restored at 0940 CDT.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(D) as an event or condition that could have prevented fulfillment of a safety function.

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.

AGREEMENT STATE REPORT - LOST EXIT SIGN
The following information is a summary of the report provided by the Maine Radiation Control Program (Maine RCP) via email:
At 0856 EDT, on September 4, 2025, the radiation safety officer (RSO) for the University of Maine Orono contacted the Maine RCP and reported that a tritium exit sign located underneath the UMaine Orono stadium bleachers was discovered to be missing. The current activity would be approximately 17.5 Ci due to decay.
The RSO contacted the members of the University of Maine Facilities Maintenance department, as well as contractors working on site, and it was relayed that heavy construction had been occurring in the facility during the last two months, and that the sign may have been damaged during cleaning. It was surmised that the sign was likely disposed of in the trash, but this could not be directly confirmed by anyone. The RSO will continue to gather additional information that will be included in a written report to be submitted within 30 days.

AGREEMENT STATE REPORT - STOLEN GAUGE
The following information was provided by the California Department of Public Health, Radiologic Health Branch (the Department) via email:
"On September 4, 2025, at 0930 PDT, the radiation safety officer (RSO) notified the Radiologic Health Branch that a CPN moisture density gauge had been stolen from a locked trailer at their construction jobsite. The construction manager noticed the company's trailer was unsecured and notified NMG Geotechnical. The gauge was secured within an internal locked cabinet inside the trailer, inside its locked transportation case that has the company name and contact number affixed. The gauge's trigger lock was confirmed to be engaged.
"The City of Carlsbad Police Department was notified, and a theft report was recorded. Maurer Technical Services was also notified. NMG Geotechnical will post a reward for information leading to the return of the stolen equipment. The Department will continue to investigate this event. "

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."
