Event Notification Report for October 11, 2023

AGREEMENT STATE REPORT - DISCONNECTED RADIOGRAPHY SOURCE

The following information was provided by the New Mexico Radiation Control Bureau via phone:

On October 2, 2023, at 1430 MDT, a radiography camera source became disconnected from its cable while still inside the guide tube during operations at a fabrication facility in Loving, NM. The device was described as a QSA D880 Model A424-9 camera with a 79.7 Ci iridium-192 source, serial number: 76167M. The licensee reconnected the source and secured the source inside the device in the shielded position by 2100 MDT. There were no public or occupational overexposure related to the source being disconnected from its control cable.

AGREEMENT STATE REPORT - MEDICAL UNDERDOSE

The following information was provided by the Oregon Department of Health Radiation Protection via email:

"At 1000 PDT on September 21, 2023, during an administration of a split-dose of Y-90 [yttrium] SirSpheres to the liver, the first dose was not completely delivered to the patient. The second dose, same lobe but a different site, was delivered completely. (First prescribed dose: 7.2mCi; First delivered dose: 5.614 mCi)

"The physician does not believe additional treatment will be needed but the case will be discussed by the licensee in a follow-up conference. The senior radiologist believes there was a `clump of spheres' remaining at the hub of the syringe for the first dose, resulting in under-dosing the patient by more than 20 percent.

"Corrective action is still to be determined."

Oregon Event Report Number: 23-0051

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 - LOSS OF CONTROL

The following information was provided by the Florida Bureau of Radiation Control [the Bureau] via email:

"On October 4, 2023, a gamma density gauge (DensityPro Gamma Density System, Model Number 5201A, 20 mCi Cs-137) was discovered in a rejected load of scrap metal at NuCor Steel. The Bureau inspector took custody of the gauge and transported it to Orlando. Upon further cleaning, the description plate revealed a serial and model number. The gauge was determined to belong to James Hardie Building Products (licensee). The licensee will be contacted and further corrective actions will be referred to the materials group at the Bureau."

Florida Incident number - FL23-152

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.

FITNESS-FOR-DUTY VIOLATION

The following information was provided by the licensee via email:

A non-licensed employee supervisor failed a test specified by the fitness for duty testing program. The individual's authorization for site access has been terminated.

The NRC Resident Inspector has been notified.

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."

OFFSITE NOTIFICATION - SPURIOUS ALARM ACTUATION

The following information was provided by the licensee via fax:

"On October 10, 2023, at 1553 CDT, Cooper Nuclear Station (CNS) was notified of a spurious actuation of a single alert notification system siren in Nemaha, Nebraska. The CNS Emergency Alert System (EAS) was not activated. The actuation occurred during siren testing conducted at approximately 1545 CDT. No emergency conditions are present at Cooper Nuclear Station.

"A press release from Nebraska Public Power District is not planned at this time.

"This condition is reportable under 10CFR 50.72(b)(2)(xi) for any event or situation for which a news release is planned or notification to other government agencies has been or will be made which is related to heightened public or government concern.

"The NRC Senior Resident Inspector has been notified."
