REACTOR COOLANT SYSTEM PRESSURE BOUNDARY DEGRADED
The following information was provided by the licensee via email:
"On October 9, 2023, during the Palo Verde Nuclear Generating Station Unit 1 refueling outage, while performing a small nozzle inspection in support of boric acid walkdowns, boric acid leakage was found on the area of the weld of a pressurizer thermowell. At 1507 MST, non-destructive examination of the weld indicated leakage through the reactor coolant pressure boundary. The exam result constitutes welding or material defects in the primary coolant system that are unacceptable under ASME Section XI. This event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(A).
"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 SOURCE FOLLOWING VEHICLE ACCIDENT
The following information was provided by the North Dakota Department of Environmental Quality (DEQ), Radiation Control Program via phone and email:
The Radiation Safety Officer (RSO) for DMS Health Technologies Incorporated informed the North Dakota DEQ that a mobile nuclear medicine truck was involved in a vehicle accident around 1400 CDT, one to two miles east of Lakota, ND on Highway 2.
The RSO reported that a 10 mCi Co-57 sheet source was unaccounted for. One red ammo can containing a CS-137 and a Ba-133 source, as well as a 500 nanocurie rod source, were found undamaged at the scene.
North Dakota Highway Patrol is currently on the scene.
NMED Number: ND230002
National Response Center report number: 1381310.
* * * UPDATE ON 10/9/23 AT 1845 EDT FROM JANELL ANDERSON TO ADAM KOZIOL * * *
The licensee's RSO contacted North Dakota DEQ to report that the missing Co-57 source had been located at the scene of the vehicle accident.
Notified R4DO (Kellar), NMSS, ILTAB, and CNSC (email).
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.
