Event Notification Report for February 07, 2025

AGREEMENT STATE REPORT - MEDICAL EVENT

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

"The Agency was contacted after hours on 01/29/2025 by Rush University Medical Center to advise of a reportable underdose of radioactive material [that occurred on 1/29/2025]. Reportedly, the patient received only 40 percent of the prescribed therapeutic dose of Y-90 microspheres. Inspectors completed a reactive inspection [on 01/29/2025] and are awaiting additional details from the licensee. The patient will be re-treated and no adverse consequence is anticipated. Updates to this report will be made as they become available."

Illinois Item Number: IL250004

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.

AGREEMENT STATE REPORT - ORPHAN SOURCE

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

"On the afternoon of 01/29/2025, Agency staff responded to a radiation portal alarm at Alter Metal Recycling in Rockford, IL. The source of the alarm was found to be a generally licensed dew point measuring device, containing a radium-226 source [with 7 microcuries of activity]. A smear was taken and indicated no contamination. The device was impounded by the Agency, pending contact with the device owner and proper disposal. Updates to this report will be made as they become available."

Illinois Item Number: IL250005


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 - OCCUPATIONAL EXPOSURE

The following is a summary of information provided by the New Mexico Rad Control Program via phone and email:

On January 31, 2025, at 0955 MST, RAP (Radiological Assistance Program) Team 4 of the Department of Energy reported that an individual from Evolution Well Services went to Baptist Hospital in San Antonio, TX stating radiation poisoning from transporting radioactive material (fracking density gauge; 20 mCi of cesium) from Texas to Jal, New Mexico. The RAP Team 4 was asked by New Mexico to investigate and are in route to survey the vehicle carrying the gauge. The RAP Team 4 will report back to New Mexico with their findings. Developments will be updated as new information is received.

AGREEMENT STATE REPORT - ABANDONED SOURCES

The following information was provided by the Massachusetts Radiation Control Program via email:

"On 1/8/2024, area portal monitors at a dump site (Republic Services) alarmed. On 1/9/2025, a consultant was called and arrived at the scene. The consultant discovered an empty vial giving a dose rate of 4.1 mR/hr on contact. The vial had a marking which looked to have been removed before it was disposed.

"On 1/30/2025, three more vials were discovered in the same trash load. The vials were full of thin solid rods and maxed out the meter available at the dump site. The consultant was called back to the site and arrived on 1/31/2025. The consultant measured 40-50 mR/hr on contact for two of the vials, and 100 mR/hr on contact for the third vial. The dose rate with all of the vials in one bag measured 1.5 mR/hr at two feet from the bag. The consultant noted that the markings were removed from these vials, but a label reading 'radium' was still visible. The vials were placed in a secure location at the facility. A member of Massachusetts Division of Radiation Control staff was on-site on 1/31/2025, to ensure all material was handled appropriately.

"Assuming all of the vials contain radium-226, with a dose rate of 1.5 mR/hr at 2 feet, a rough calculation estimates approximately 0.7 mCi of radium-226 exists in the vials.

"This quantity of found material is immediately reportable to NRC pursuant to 105 CMR 120.281."

AGREEMENT STATE REPORT - PACKAGE CONTAMINATION LIMITS EXCEEDED

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

"On 1/31/2025, at approximately 1420 CST, the Agency was notified of a package received that exceeded limits from the radiation safety officer (RSO) at Baylor Scott and White Medical Center in College Station, Texas. The report was two cases from RLS Pharmacy in Temple were contaminated with Tc-99m. The initial results from wipe tests performed by the nuclear medicine technologist were 22.1k and 87.7k disintegrations per minute (dpm), respectively. No other contamination was present.

"There was no contamination found anywhere in the hospital or the courier vehicle. The courier vehicle and the courier were surveyed after returning to the pharmacy. Packages were surveyed prior to leaving the pharmacy and no contamination was present.

"Further Information will be provided in accordance with SA-300."

Texas Incident Number: 10164

Texas NMED Number: TX250008

AUTOMATIC REACTOR TRIP

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

"At 1002 EST, on February 5, 2025, with Unit 2 in mode 1 at 100 percent power, the reactor automatically tripped due to lowering 'B' steam generator level. All control rods fully inserted into the core and the auxiliary feedwater system automatically started as designed in response to the full power reactor trip. The trip was not complex, with all systems responding normally post-trip. There was no equipment inoperable prior to the event that contributed to the reactor trip or adversely impacted plant response.

"Operations responded and stabilized the plant. Decay heat is being removed by discharging steam to the main condenser using the condenser steam dump valves. Unit 1 is not affected and remains at 100 percent power and stable. Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). Additionally, this event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that resulted in a valid actuation of the auxiliary feedwater system.

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

FITNESS FOR DUTY

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

A non-licensed employee supervisor had a confirmed positive during a random fitness for duty test. The employee's unescorted access to the plant has been revoked.

The NRC Senior Resident Inspector has been notified.
