Event Notification Report for November 18, 2022

AGREEMENT STATE - RADIOACTIVE SOURCE FOUND IN SCRAP YARD

The following information was provided by the Commonwealth of Virginia Radioactive Materials Program (RMP) via email:

"On November 3, 2022 at 0935 EST, the RMP received a call from Gerdau Metals Recycling Company that a load of scrap metal being received set off the radiation monitoring detector. The load was dumped and surveyed with a hand held survey meter. A Cs-137 dose calibrator reference source (E-vial) was found among the scrap metal in its accompanying lead shield complete with markings. The highest radiation measured on contact was 1.3 mR/hr.

"On November 4, 2022, the RMP inspector visited the site and performed a general survey to ensure that there are no other sources in the scrap metals. It was confirmed that there are no other sources in the load. The source was marked as an Amersham Model CDR.562 Cs-137 source S/N CB557 with an initial activity of 260 microcuries on 13 December 1990. The decayed activity as of 11/4/2022 is about 124.5 microcuries. The RMP inspector coordinated with a local medical physicist and determined that this source was on the list of the inventory, which was conducted in April 2007, of one of the local diagnostic medical imaging centers, whose license was terminated in January 2009. The source was supposed to be transferred to another local hospital during the termination of the license. Currently, the RMP is working with Gerdau Metal Recycling Company and a local health physicist for the proper disposal of the source. The report will be updated."

Virginia Event Report ID: VA220004

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 - PATIENT UNDERDOSE

The following information was received from the Arizona Department of Health Services (the Department) via email:

"On November 10, 2022, the Department received notification from the licensee about a medical event involving Y-90 Theraspheres. A patient was prescribed a dose of 150 Gy but was delivered 79.05 Gy, a percent dose delivered of 52.7 percent. The Department has requested additional information and continues to investigate the event."

Arizona Incident No. 22-014

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.

EN Revision Text: ALERT - SEISMIC EVENT FELT ONSITE

The following information was provided by the licensee via fax:

"An Alert has been declared at Urenco USA. An Alert is the official designation for an emergency which is contained on the URENCO USA site. No public protective actions are recommended at this time. A seismic event was detected near the facility. A 'vibratory' ground motion is felt in the Control Room, recognized as an earthquake, and verified by field personnel."

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

On 11/16/2022 at 1445 MST, Urenco USA declared an Alert (EAL SA.1) due to a seismic event felt onsite. The Headquarters Operations Officer was notified of the Alert at 1657 EST (1447 MST). No radioactive release had occurred. No structural damage had been detected. A 5.4 magnitude earthquake occurred in western Texas with an epicenter 90 miles southwest of Hobbs, New Mexico, a town close to the facility. Plant personnel are conducting walkdowns of the site.

The licensee notified state and local authorities.
