AGREEMENT STATE - COURIER VEHICLE ACCIDENT

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

"The Department was notified at 0815 [CDT] on September 27, 2024, by the licensee, that one of their courier vehicles had been involved in a vehicle accident on I-35 North, between Denton and Valley View, Texas. The accident resulted in the death of a driver of an 18 wheeler but was not related to the presence of radioactive material (RAM). The courier driver was injured with a broken leg and was transported to the hospital with non-life threatening injuries. The roadway was shut down for several hours due to diesel fuel, oil, and debris from the collision. There was no radiological involvement as part of the closure. The shipment was six `ammo' boxes containing 10 doses of F-18. Five of the containers were located in the courier vehicle and transported to a nearby hospital. The packages were surveyed on arrival at the hospital by hospital staff and placed in a secure area to await the licensee's personnel. The five packages were subsequently retrieved by the licensee. The sixth package was ejected from the transport vehicle and was not transported to the hospital with the other five packages. The licensee retrieved and surveyed [the sixth] package at the accident scene. There was no contamination or release of RAM. The investigation [by the Department] continues."

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 - DAMAGED MOISTURE DENSITY GAUGE

The following information was provided by the Colorado Department of Public Health and Environment (the Department) via email:

"On 09/26/2024, the Department was notified by the CTL/Thompson, Inc. radiation safety officer (RSO) that a possible incident with a moisture density gauge occurred at a job site in Granby, CO. The RSO stated he had no further information to provide [about the event]. The Department compliance lead spoke with the RSO over the phone and identified the assistant RSO (ARSO) over that job site. [When contacted] the ARSO stated that a technician was driving on a job site when the incident occurred. The latches were closed on the transportation case, but not fixed with locks since additional testing was going to be performed. While driving over the uneven terrain of the job site, the truck jostled causing the tailgate to open and the transportation case flipped over towards the edge of the truck bed. The latches on the transport case released and caused the gauge (Troxler model 3430, 8 mCi Cs-137, 40 mCi Am-241/Be) to come out and land on the ground, resulting in damage to the gauge."

Colorado Event Report ID: CO240024

AGREEMENT STATE REPORT - STUCK SHUTTERS

The following information was provided by the Louisiana Radiation Protection Division via email:

"This event is considered an equipment failure with open shutters. The failure occurred while Syngenta Crop Protection was performing their required license condition shutter checks on August 29, 2024. There were two nuclear gauges that failed the shutter operational checks.

"The two nuclear gauges are in the failed open shutter position.

"The first gauge is a Texas Nuclear series 5100, model 5189 and serial number 51, with a source activity of 25 mCi [Cs-137] and the second gauge is a RONAN Engineering, model SA1-F37 and serial number 6268CM, with a source activity of 2000 mCi [Cs-137 and Co-60].

"Syngenta Crop Protection is planning to bring a third party to work on or replace the nuclear gauges. BBP Sales will be the third party. Syngenta Crop Protection plans on having BBP Sales out to the facility as soon as possible."

LA Event Report ID Number: LA20240010

AGREEMENT STATE REPORT - FOUND GAUGE

The following information was provided by the California Radiologic Health Branch (RHB) via email:

"RHB was notified on 9/30/24 that Los Angeles (LA) County Radiation Management recovered an InstroTek CPN MC-1 Elite number 31069 (containing nominally 50 mCi Am-241/Be and 10 mCi Cs-137 sources) from an apartment complex in Long Beach, CA. Long Beach Fire and Police Department responded to a call from the apartment complex management that the transportation box was left in their parking garage for approximately a week. An LA County health physicist verified that the box did contain a moisture density gauge, which is owned by Leighton and Associates according to transportation paperwork found inside the unlocked transportation case. The Cs-137 source rod was locked in the shielded location. The gauge was removed from the property and secured in a storage locker.

"RHB contacted the company radiation safety officer, who was unaware that the gauge was missing. Follow-up investigation is in process to determine how and when the gauge went missing and why the licensee was unaware that it was missing."

OFFSITE AGENCY NOTIFICATION

The following information was provided by the licensee via phone and email:

"At 1000 CDT, on October 3, 2024, Kewaunee Power Station was informed that the Wisconsin Department of Health Services (WDHS) was notified of an asbestos worker qualification issue specific to several workers at the Kewaunee Solutions Decommissioning Project. This notification was made by a subcontractor performing asbestos abatement work at the site and involves a lack of documentation of the worker qualifications.

"The NRC Regional Inspector has been notified."

LOSS OF SEISMIC MONITORING FOR EMERGENCY PLAN ASSESSMENT

The following information was provided by the licensee via phone and email:

"At 2235 on 10/03/2024, the Vogtle 1 and 2 seismic monitoring panel experienced an electrical fault, rendering the panel nonfunctional. Compensatory measures for seismic event classification have been implemented in accordance with Vogtle procedures.

"This is an eight-hour, non-emergency notification for a loss of emergency assessment capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the seismic monitoring panel is the method for evaluating that an operational basis earthquake (OBE) threshold has been exceeded following a seismic event. This is in accordance with Initiating condition `seismic event greater than OBE levels' and emergency action level HU2.

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

PART 21 - NON COMPLIANT CONTACTORS

The following is a synopsis of information provided by MPR Associates, Inc. (MPR) via fax:

On August 9, 2024, MPR received information that electrical contactors (Models AF80 and AF116) provided by Asea Brown Boveri Ltd. (ABB) contain a microcontroller. The fact that these contactors contain a microcontroller was not included in MPR's analysis during their commercial grade dedication process. Two contactors were supplied to Beaver Valley Power Station (ABB AF116-30-11-13) where one was installed in the excitation system for one emergency diesel generator. Five contactors were supplied to Davis-Besse Nuclear Power Station (ABB AF116-30-11-13), but none were installed.

MPR is currently working to provide information to support continued use of the installed contactors. MPR is also working to identify a replacement contactor that is suitable for the application.

AGREEMENT STATE REPORT - LEAKING SEALED SOURCES

The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:

"On September 26, 2024, the radiation safety officer at Bard Brachytherapy, Inc. (the licensee) notified the Agency of a contamination event within a restricted area presumably resulting from the receipt of leaking Pd-103 brachytherapy seed or seeds. Seventy-one (71) Pd-103 seeds (solid/sealed sources, Theragenics Corp. Model 200 TheraSeed), each with an approximate activity of 1.6 mCi, were received on September 26, 2024, from Theragenics Corporation for loading into a Mick applicator. No contamination was noted on the incoming package and the [transportation information] on the package label was verified. As a result, no exposures to the carrier or members of the public are anticipated. However, upon working with the Pd-103 seeds within the restricted area, personnel surveys evidenced contamination on PPE. At the time of notification, the process of assessing the extent of contamination and decontaminating had begun. Personnel surveys had been performed and indicated contamination on clothing/shoes, with no skin contamination reported.

"Agency staff performed a reactive inspection on September 27, 2024. Inspectors verified that contamination was limited to the restricted area (loading room) and that no contamination to the skin was identified. The licensee is working to quantify the contamination and assess any potential skin dose to workers. At this time, Agency staff do not anticipate any occupational exposures in excess of regulatory limits as a result of this incident. No public exposures resulted from this incident and all contamination was limited to restricted areas. All 71 seeds had been placed in secured storage and radiation safety staff had successfully cleaned contaminated areas (floor, bench top, equipment, chairs) and had placed contaminated clothing (shoes, lab coats, gloves, a shirt, a pair of jeans) for decay-in-storage. Regarding reportability, the licensee committed [to Illinois] to performing leak tests of the sources once assembled. Therefore, [Illinois-specific] reporting requirements apply. There may not be an equivalent NRC requirement. There was no limit on contamination within the restricted area exceeded by the licensee. It is unlikely the potential for uptake of more than one annual limit on intake (greater than 3 seeds) would have been feasible within 24 hours. Therefore, unless there is a reportable occupational exposure, this matter may not be NRC reportable. Regardless, the incident will be shared with Georgia program staff as well. This report will be updated with the information obtained from the licensee's written report."

Illinois item number: IL240022

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA FAILURE

The following report was received via email from the California Radiologic Health Branch (RHB),

"The Mistras Group's radiography crew was working at a temporary job site (inside a tank) on Friday, August 30, 2024. During the first exposure for the day at 0845 [PDT], the radiographer extended the source assembly and then felt the crank mechanism spin freely, causing the inability to retract the source assembly into the shielded position (a critical component failure). Emergency procedures were implemented; both radiographers extended their controlled radiation area boundary and monitored the area while the radiation safety officer (RSO) was notified at 0852. Source recovery personnel from Mistras Group's Torrance Lab arrived at 1040 to evaluate the situation. A recovery plan was discussed and implemented by the recovery radiographer. He entered the tank, opened the crank assembly, and determined the drive cable was not inside the housing. He opened the exposure side of the crank assembly and saw the end of the drive cable. He was able to retract the source assembly drive cable until the source assembly latched and locked inside the exposure device. This was accomplished at 1105. The RSO made a telephone notification to RHB at 1801 to report the event, but it went to voice mail, so he left his name and phone number. However, the voice mail was not forwarded and the RSO did not follow-up the next week to determine if his voice mail was received. A 30-day written notification of the event, per 10 CFR 34.101 was sent to RHB and received on September 28, 2024. Radiation exposures did not exceed 5 mrem for any involved personnel."

California Report Number: 093024

RADIOGRAPHY CAMERA FAILURE

The following is a summary of information provided by Mistras via phone:

A Mistras two-person radiography crew was working at a customer site with a 61 Ci Ir-192 source from an elevated platform. The crew went to retract the source, but it did not move after several attempts. The crew then realized the source was disconnected from the drive cable.

The crew expanded the radiography boundaries to limit exposure to 2 mR/hr. The crew notified site personnel and is monitoring the posted boundaries until the source is secured. Additional Mistras personnel are en-route to retrieve the source.

No personnel exposures due to the malfunction have occurred.

* * * UPDATE ON 10/02/24 AT 0900 EDT FROM MATT KIM TO ERIC SIMPSON * * *

The following is a summary of information provided by Mistras via phone:

On October 2, 2024, at 0120 EDT, a repair crew arrived onsite to perform repairs to the radiography camera. The crew successfully repaired the device and retracted the source into the shielded position at approximately 0320 EDT.

No personnel overexposures occurred due to the radiography camera failure.
