EN Revision Text: AGREEMENT STATE REPORT - FOUND SOURCE

The following is a summary of information provided by the North Carolina Department of Health and Human Services, Radioactive Materials Branch (NCRAM) via phone and email:

The Florida Department of Health, Bureau of Radiation Control (FLBRC) responded to a call from the public and impounded 2 lead pigs possessed by a Florida resident. One lead pig held an estimated 50 mCi Ra-226 nasopharyngeal radium applicator with a 25 R/hr on contact dose rate. The second pig was empty. FLBRC determined that the lead pigs originated from a residence located in Rocky Mount, NC, owned by the family of the Florida resident. FLBRC informed NCRAM of the missing Ra-226 source. NCRAM located the second source, unshielded, in the garage of the North Carolina residence. The source in North Carolina was removed from the residence and is currently secured at NCRAM.

NCRAM reports dose rates of 400 mR/hr at 30 cm, and 50 mR/hr at 1 meter, for the found Ra-226 source. Exposures to members of the public are unknown, and the licensee is unknown.

An NMED written report will follow. All data is confirmed but preliminary.

The second source was picked up from NCRAM by SpectronRX and will be shipped for disposal.

Notified NMSS Event Notifications via 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.

AGREEMENT STATE REPORT - STUCK-OPEN GAUGE SHUTTER

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

"On September 17, 2026, the license notified the agency regarding a gauge whose source shutter mechanism had failed to function as intended. The gauge, a Texas Nuclear model 5205, contains a 100 mCi Cs-137 sealed source. The licensee reported that the gauge was discovered with the source shutter stuck in the open position. Open is the normal operating position. The discovery was made by the licensee on September 17, 2026, during a routine inspection.

"The licensee stated that there is no risk of additional radiation exposure to members of the public or radiation workers due to this on/off mechanism failure. The licensee has contacted a service provider to have the gauge repaired.

"Additional information will be provided in accordance with SA300 Reporting requirements."

Texas incident number: 10330
NMED number: TX260040

LEAKING SEALED SOURCE

The following information was provided by the licensee via phone:

On September 17, 2026, at 1300 CDT, the DHA radiation safety officer (RSO) at Fort Sam Houston was notified of a leaking 13.6 mCi Ni-63 sealed source from a gas chromatograph.

Wipes and leak tests were conducted. The wipes tested positive and the RSO is awaiting the results of the leak test. There were no reported exposures. The notification is being made in accordance with 10 CFR 31.5(c)(5).

Gas chromatograph information:
Manufacturer Agilent Technologies
Model: 7890A
S/N: US 13371009

OFFSITE NOTIFICATION

The following information was provided by San Onofre Nuclear Generating Station (SONGS) via phone and email:

"On September 23, 2026, between approximately 2000 and 2200 PDT, a planned wastewater transfer continued after the intended transfer period, resulting in an unplanned discharge of approximately 5,000 gallons into the Unit 2 storm drain/intake pathway rather than completing the intended controlled wastewater discharge path. The Unit 2 intake conduit leads to the Pacific Ocean. The source of the water was mostly groundwater, with some concrete cutting water.

"On September 24, 2026, at 1457 PDT, SONGS notified the San Diego Regional Water Quality Control Board of the unplanned discharge associated with the SONGS NPDES [National Pollutant Discharge Elimination System] permit. This NRC notification is being made under 10 CFR 50.72(b)(2)(xi) based on the notification to an offsite government agency.

"Samples were collected at three locations for analysis. [Total suspended solids] (TSS) was 16 mg/L and pH was 10.6. Oil and grease laboratory results are pending. Tritium was detected at an approximate level of 3000 picoCuries/L. The pH value is in excess of the permit level of 9. The remaining sample values were within limits. Based on these preliminary analytical results and currently available information, Southern California Edison does not believe the release poses a threat to ocean water quality."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

SONGS will notify NRC Region IV of this event.
