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 is a summary of information provided by the New Mexico Environment Department via phone and email:

During an intravenous administration of 130 microcuries of Xofigo (Ra-223 dichloride) via the left hand, the patient experienced a burning sensation. The nuclear medicine technologist stopped the administration. The authorized user (AU) determined that an infiltration of Xofigo had occurred in the left hand of the patient and began intervention techniques (i.e., warm compress, massage, arm elevation, etc.). Shortly after the infiltration, the nuclear medicine technologist administered the remaining Xofigo dosage through the patient's right hand per the instructions of the AU. Count rate measurements and imaging was performed on the infiltrated site (patient's left hand) on June 3, 2026, and June 4, 2026. Activity and dosimetry calculations were performed, and results were confirmed on June 8, 2026. It was determined that 14 microcuries of Ra-223 infiltrated in the patient's left hand, which resulted in a dose of 3.2 Sv to the skin of the left hand. The licensee has performed a couple of follow-up visits with the patient to monitor symptoms and will continue observation over the next several weeks for any deterministic effects.


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 - DAMAGED SOURCE

The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:

"On June 9, 2026, the Department was notified by the licensee that a Troxler model 4640-B was run over at a job site, the plastic case was damaged, and the source rod appeared to be bent. Because the source rod appeared to be bent, they did not attempt to operate it. The gauge contained an 8 millicurie cesium-137 source. The radiation safety officer (RSO) stated the gauge would be returned to the normal storage area and on June 10, 2026, taken to the manufacturer for inspection. The RSO stated they were traveling to meet the technicians who were using the gauge and would perform radiation surveys of the gauge once they had possession of it. The RSO stated, based on the pictures, it did not appear that there was a risk of additional exposures. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - MEDICAL EVENT

The following information was provided by the California Radiation Control Program, specifically, the Los Angeles County Radiation Management via phone and email:

"The radiation safety officer at Kaiser Permanente Medical Care Program of Southern California contacted L.A. County Radiation Management on June 9, 2026, at approximately 1242 [PDT] to report a medical event that occurred on June 8, 2026.

"The event involved an underdose to a patient during the administration of Lu-177 Pluvicto to a patient. The prescribed dosage was 200 mCi, however, based on preliminary estimates, the patient received only approximately 10 to 15 percent of the intended dosage. An unknown amount of the radiopharmaceutical was spilled onto the disposable waterproof padding placed underneath the administration apparatus and a small amount was observed on the arm and clothing of the authorized user. Decontamination procedures were performed.

"Kaiser Permanente will conduct an investigation of the incident to determine the root cause and will develop and implement a corrective action plan. A follow-up written report will be submitted within 15 days in accordance with reporting requirements."

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA CABLE DRIVE FAILURE

The following information was provided by the New Mexico Radiation Control Program (the Program) via email:

"On June 9, 2026, at approximately 1200 MDT, a radiography crew operating a QSA Delta 880 camera with a 21 Ci Ir-192 source experienced a drive cable failure. The cable reportedly broke approximately 4 inches from the tip during operations. The event occurred southwest of Malaga, New Mexico.

"The radiographer immediately notified the radiation safety officer (RSO), who responded to the site and successfully performed source retrieval. The licensee is authorized for source retrieval activities. The source was fully returned to a safe and shielded position, and the device was secured. There was no indication of radiological exposure above regulatory limits, and no contamination or risk to the public has been identified at this time. The crank assembly associated with the failure was removed from service. Following retrieval, the equipment was evaluated by the RSO, and operations resumed using the device with the defective component no longer in use.

"Dosimetry reports have been requested for the RSO, radiographer, and assistant. A full written report is expected within 30 days.

"This event was reported to the Program at approximately 1151 MDT on June 10, 2026."

FITNESS FOR DUTY

The following information was provided by the licensee via phone and email:

"On June 15, 2026, at approximately 1749 [EDT], positive test results were confirmed on a random fitness for duty (FFD) test for a [contract] supplemental supervisor. The supplemental supervisor held unescorted access at Surry and North Anna Power Stations. No work on safety-related components was performed during this access period at Surry or North Anna. Individual was onsite to perform a walk down. Individual was denied unescorted access at Surry and North Anna Power Stations. FFD Evaluation will be submitted by the Dominion Energy Supervisor or designee at Surry and North Anna Power Stations.

"The NRC Resident Inspector was notified."

PART 21 - GENERAL ELECTRIC RELAY FAILURE

The following is a summary of information provided by the licensee via email:

Curtiss Wright (CW) is submitting an evaluation report of a potential defect of a CW supplied relay, General Electric part number: 12IAV69A1A.
On January 26, 2026, Constellation notified Curtiss-Wright about the failure of a relay that was provided to Constellation on July 18, 2025. According to Constellation, the relay passed pre-installation bench testing but failed the functional test after replacement.
Constellation found that the power was no longer applied to the relay and had blown bus fuses. Checks of the new relay (failed relay) showed that wires were crossed, which shorted out the circuit.
On May 14, 2026, the relay was received by Curtiss-Wright from Constellation and Curtiss-Wright verified Constellation's assessment to be correct.

Because CW cannot establish a root cause, the following action is recommended:

CW has modified the dedication plan to specifically inspect the wiring to confirm the wiring of new items is equivalent to the originally qualified test sample prior to functional testing.
These actions should preclude a possible recurrence of this failure mechanism.

CW has not supplied P/N: 12IAV69A1A to any other end users.
