EN Revision Text: LOSS OF COMMUNICATIONS AND ASSESSMENT CAPABILITIES
The following information was provided by the licensee via email:
"On 02/06/2023 at 0416 EST, the Constellation Emergency Response Organization (ERO) Notification Database System uploaded data files into the Mass Notification System (Everbridge) which is used to notify ERO personnel when activated. At 0630, the individual reviewing the uploaded files discovered that the data files did not upload properly and that Everbridge may not notify all ERO individuals within the required 10 minutes of system initiation. Constellation resolved the issue by 0752.
"During the time period of 0416 to 0752, control room operators would have been unaware that the ERO notification was not successful. Therefore, this issue constitutes a loss of offsite communications capability and is reportable under 10 CFR 50.72(b)(3)(xiii), 'The licensee shall notify the NRC as soon as practical and in all cases within eight hours of the occurrence of any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability (e.g., significant portion of control room indication, Emergency Notification System, or offsite notification system).' This loss of offsite communications capability affected all Constellation nuclear stations.
"There was no impact on the health and safety of the public or plant personnel. Each affected station NRC Resident Inspectors have been or will be notified."
The effected plants are Braidwood (EN 56352), Byron (EN 56354), Calvert Cliffs (EN 56355), Clinton (EN 56356), Dresden (EN 56361), FitzPatrick (EN 56362), Ginna (EN 56363), LaSalle (EN 56364), Limerick (EN 56360), Nine Mile Point (EN 56359), Peach Bottom (EN 56358), and Quad Cities (EN 56357).

EN Revision Text: AGREEMENT STATE REPORT - EXCESSIVE EXPOSURE
The following information was provided by the Louisiana Department of Environmental Quality (LDEQ) via email:
"LDEQ was notified by the Acuren Inspection Radiation Safety Officer (RSO) via the DEQ Radiation Hotline at approximately 1240 EST on February 6, 2023, concerning a possible industrial radiography camera excessive exposure. According to the RSO, at approximately 1025 at the Shell Norco Refinery, a possible excessive exposure occurred. Two radiographers did not crank the Ir-192 source completely back in the camera. The first radiographer had his hand close to where the source was located for approximately 10 seconds. The estimated whole-body exposure for both radiographers is 448 mR and the worst-case exposure to the hand for one of the radiographers is 96.86 R. The licensee is currently doing a reenactment to have a better idea of the potential exposures. The licensee is sending the radiographers for a blood count. The camera is a QSA Global 880 Delta (s/n D13733) with 41 curies of Ir-192 (s/n 54759)."

EN Revision Text: AGREEMENT STATE REPORT - LOST BRACHYTHERAPY SEEDS
The following information was provided by the Illinois Emergency Management Agency, Division of Nuclear Safety, Radioactive Material Branch (DNS-RAM) via email:
"DNS-RAM was notified on 2/6/23, by Bard Brachytherapy (IL-02062-01) that a package of radioactive brachytherapy seeds was lost while in the care of a common carrier. The package was shipped on 2/3/2023, from the licensee's facility in Carol Stream, IL to Centrum Radiotherapie in Kortrijk, Belgium. Total package activity at the time of shipment was 65.62 millicuries of I-125 (ninety STM-1251 seeds, each at 0.430 millicuries). DNS-RAM is currently seeking updated information on the last reported location of the package - which is believed to have been in South Africa. This does not represent a significant public safety hazard and there is no indication of intentional theft or diversion.
"Updates will be provided as they become available."
Illinois Event Number: IL230003
* * * UPDATE ON 2/9/23 AT 1201 EST FROM GARY FORSEE TO ADAM KOZIOL * * *
The following information was provided by the Illinois Emergency Management Agency, Division of Nuclear Safety, Radioactive Material Branch (DNS-RAM) via email:
"Licensee advised this morning that the package has been located. Updates will be provided as they become available."
Notified R3DO (Szwarc), NMSS Events Notification, and ILTAB (email).
* * * UPDATE ON 2/15/23 AT 1331 EST FROM GARY FORSEE TO KAREN COTTON * * *
"This matter is considered closed."
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.

"On 02/06/2023 at 0416 EST, the Constellation Emergency Response Organization (ERO) Notification Database System uploaded data files into the Mass Notification System (Everbridge) which is used to notify ERO personnel when activated. At 0630, the individual reviewing the uploaded files discovered that the data files did not upload properly and that Everbridge may not notify all ERO individuals within the required 10 minutes of system initiation. Constellation resolved the issue by 0752.
"During the time period of 0416 to 0752, control room operators would have been unaware that the ERO notification was not successful.

The following information was provided by Constellation via email:
"On 02/06/2023 at 0416 EST, the Constellation Emergency Response Organization (ERO) Notification Database System uploaded data files into the Mass Notification System (Everbridge) which is used to notify ERO personnel when activated. At 0630, the individual reviewing the uploaded files discovered that the data files did not upload properly and that Everbridge may not notify all ERO individuals within the required 10 minutes of system initiation. Constellation resolved the issue by 0752.
"During the time period of 0416 to 0752, control room operators would have been unaware that the ERO notification was not successful. Therefore, this issue constitutes a loss of offsite communications capability and is reportable under 10 CFR 50.72(b)(3)(xiii), 'The licensee shall notify the NRC as soon as practical and in all cases within eight hours of the occurrence of any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability (e.g., significant portion of control room indication, Emergency Notification System, or offsite notification system).' This loss of offsite communications capability affected all Constellation nuclear stations.
