Event Notification Report for March 31, 2023

AGREEMENT STATE REPORT - POSSIBLE OVEREXPOSURE OF RADIOGRAPHER

The following information was received from the Louisiana Department of Environmental Quality (the Department) via email:

"On March 23, 2023, Nondestructive & Visual Inspection, L.L.C. notified the Department that there was a possible overexposure. The event occurred on March 21, 2023. The industrial radiography crew was working with a SPEC 150 (serial number: 2256) with 80 Ci of Ir-192. The source serial number was EA1810. The industrial radiography crew was working on a pipeline in Red River Parish, Louisiana.

"The industrial radiographer was not wearing his dosimetry badge, pocket ion chamber, and rate alarm meter when he realized the radiation source had not been cranked back into a shielded condition and was out to the end of the source guide tube with a collimator.

"The radiographer has had bloodwork done to send to REACT for testing. The calculation for exposure ranged from 1.8 rem to 21 rem. The industrial radiography source is now secured and properly shielded within the SPEC 150 camera."

Louisiana Event Report ID No.: LA20230005

AGREEMENT STATE REPORT - FOUND SOURCE

The following information was received from the California Department of Public Health, Radiologic Health Branch (RHB) via email:

"On March 16, 2023, SA Recycling reported the discovery of a radioactive source within a bin of shredded metal from their onsite operations when it was screened at the scale-house radiation detectors. The container was dumped out and the contents sorted using tools by SA Recycling personnel until the source of the radiation was located. RHB was notified of the event after the sorting was completed using a Ludlum 3 with a 44-10 NaI detection probe and the source had been removed to a secure onsite storage area.

"The next day a state inspector visited the site and verified the radioactive source was in a secure location. The source was put in a lead shielded container by the inspector and left in the locked storage area (the dose rate on the lead storage container was approximately 0.25 mR/hr). On March 23, 2023, the source was determined by inspectors to be Gd-153 with an approximate activity of 100 mCi.

"The source will be taken into the custody of the State, and a dose assessment will be made of the SA Recycling personnel involved in the search for the source."

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 - DISCONNECTED RADIOGRAPHY SOURCE

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

"The New Mexico Radiation Control Bureau received a report from the licensee that, as they were conducting radiography work in a pipeline in southern New Mexico near Carlsbad, a source disconnected. While the source was being cranked back into the radiography camera, it disconnected. The area around the camera has been secured and only the licensee personnel are on location to keep the perimeter and the source secured while they await a crew to arrive to retrieve, secure, and return the source to the camera. A formal report will follow in a separate email."

OFFSITE NOTIFICATION DUE TO ON-SITE FATALITY

The following information was provided by the licensee via email:

"At approximately 0037 CDT on March 30, 2023, a non-responsive individual at South Texas Project (STP) Electric Generating Station was transported offsite for treatment at an offsite medical facility. The offsite medical facility notified STP Nuclear Operating Company that the individual had been declared deceased as of 0103 CDT.

"The fatality was not work-related, and the individual was outside of the radiologically controlled area.

"This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi) as a four-hour, non-emergency notification for an on-site fatality and notification of another government agency. OSHA will be notified.

"The NRC Resident Inspector has been notified."
