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."

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 - SOURCE LOST IN TRANSIT

The following information was provided by the New Jersey Radiation Materials Program (RMP) via email:

"On 2/7/2023, RMP staff was notified via the radiation safety officer that a Cardiogen generator with 100 mCi of Sr-82 and 71 mCi of Sr-85 was considered lost in transit by the common carrier. On 1/31/2023, the licensee sent the generator to a customer via a common carrier. Due to delays, the licensee's logistics team contacted the common carrier for a status update on the generator. On 2/7/2023, it was declared lost and its last location was at the common carrier hub in Memphis, TN."

AGREEMENT STATE REPORT - DAMAGED PORTABLE GAUGE

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

"On February 8, 2023, at approximately 1300 EST, the VRMP received a report via telephone from the licensee that a portable nuclear moisture/density gauge (Troxler Model 3440+, serial number 72924, containing 8 millicuries of cesium-137 and 40 millicuries of americium-241/beryllium) was damaged. At approximately 1115 EST on February 8, 2023, [the gauge] was hit by a 'Bobcat' compaction vehicle/machine on a temporary jobsite at a private residence. The source rod was not out at the time of the impact. The gauge is not functional as the housing and electronics sustained significant damage. The source appeared to remain intact within the safe position. The authorized user secured the area and immediately contacted his radiation safety officer (RSO) who was several hours away. The RSO then contacted the VRMP. The licensee was instructed to transport the gauge back to their storage facility in its transport container to expedite removal from the residential site before nightfall. At 1615 EST, the RSO confirmed the gauge had arrived at their office in Chantilly VA and was secured. The Virginia Office of Radiological Health will perform surveys of the gauge on February 9, 2023, and will conduct a reactive inspection to investigate the incident. This notification will be updated with additional information determined during the inspection.

"No members of the public have had close proximity to the gauge. Any potential exposure by the authorized user will be determined once surveys have been made."

EN Revision Text: AUTOMATIC REACTOR TRIP DUE TO TWO REACTOR COOLANT PUMPS TRIPPING

The following information was provided by the licensee via email:

"On February 14, 2023 at 1103 CST, Arkansas Nuclear One, Unit 1, (ANO-1) automatically tripped on reactor protection system actuation due to two reactor coolant pumps tripping.

"ANO-1 is currently stable in MODE 3 (Hot Standby) maintaining reactor coolant system pressure and temperature with main feedwater and steaming to the condenser.

"No additional safety system actuations occurred. All immediate actions were completed satisfactorily.
"There are no indications of a radiological release on either unit as a result of this event.

"This report satisfies the reporting criteria of 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A) for the reactor protection system actuation.

"The NRC Senior Resident Inspector has been notified.

"Unit 2 was not affected."

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

The licensee is investigating the cause of the two reactor coolant pump trips.

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).'
