AGREEMENT STATE REPORT - LOST SOURCES
The following report was received from the Texas Department of State Health Services (the Department) via phone and email:
"On November 15, 2024, the Department was notified by the licensee that the location of three 5 mCi (original activity in October 2021) Ge-68 rod sources could not be determined. The sources were supposedly shipped back to the manufacturer in the fourth quarter of 2022, but no receipt record was available from the manufacturer to show the sources were received. The missing paperwork was discovered during an inventory verification audit in May of 2024 by the consulting physicist. Since that time, there were many staff changes. The new technologist had been working to clean up issues and has tried to contact all the parties involved, but could not find the paperwork. Consequently, the licensee declared them lost and reported them as such to the Department on November 15, 2024. The licensee stated the sources do not pose a risk of additional exposure to any worker or member of the public. Additional information will be provided in accordance with SA-300."
Texas Incident Number: 10144
Texas NMED Number: TX240043
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.

MANUAL REACTOR TRIP
The following information was provided by the licensee via phone and email:
"At 1001 EST, on November 15, 2024, with Unit 1 in mode 1 at 100 percent power, the reactor was manually tripped due to three control element assemblies fully inserting into the core. The trip was uncomplicated with all systems responding normally post trip. Operations stabilized the plant in mode 3. Decay heat is being removed by the steam bypass control system and main feedwater. Unit 2 was not affected.
"This event is being reported pursuant to 10 CFR 50.72 (b)(2)(iv)(B).
"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 insertion of the three control rods is suspected to be caused by an electrical failure; however, the cause is still being investigated.

UNANALYZED CONDITION
The following information was provided by the licensee via phone and email:
"At 1305 CST, on November 15, 2024, it was determined that division 2 cables for the '12' emergency diesel generator start circuitry are routed through a division 1 area without adequate fire barrier separation. 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. A fire impairment and hourly fire watch have been established for the affected fire zones. Therefore, this event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72 (b)(3)(ii)(B).
"The NRC Resident Inspector has been notified."
