Event Notification Report for March 05, 2025

AGREEMENT STATE REPORT - DAMAGED RADIOGRAPHY CAMERA

The following report was received via email by the Tennessee Division of Radiation Health:

"During a scheduled work visit to the TVA Cumberland City facility, a radiography crew was descending an outside set of stairs covered with ice. The worker slipped on the stairs and released the camera which dropped approximately 20 feet to the ground. The team surveyed the area to ensure it was safe to approach the device. After ensuring the device was secured, it was placed into an overpack and transferred back to the licensee's facility. A minor amount of damage was incurred to the rear of the device. The team had no indication that the source was compromised.

AGREEMENT STATE REPORT - MEDICAL EVENT

The following information was received from the California Department of Health (CDPH) via email:

"The radiation safety officer for Hoag Hospital in Irvine called the California Office of Emergency Services to report a potential medical event that occurred during a research treatment that involved a targeted alpha radionuclide therapy. The authorized user prescribed 289 microcuries of Ac-225 in the form of FPI-2265 also known as [225Ac] PMSA imaging therapy; however, the Biodex pump used to administer the dose leaked, and only approximately 80 microcuries were administered.

"The treatment was for metastatic castrate resistant prostate cancer primarily located in bone marrow. CDPH will conduct an investigation of the circumstances of the medical event."

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 - STUCK SHUTTERS

The following report was received from the Texas Department of State Health Services (the Department):

"On February 26, 2025, the Department was notified by the licensee that during routine testing, the shutters on three nuclear gauges were found stuck in the open position. Open is the normal operating position for the gauges. The gauges are all Texas Nuclear gauge models; a '5200' model containing a 20 millicurie source, a '5201' model containing a 100 millicurie source, and a '5208' model containing a 4,000 millicurie source. All sources are cesium - 137 sources. The licensee reported that there is no risk of additional radiation exposure to members of the general public or radiation workers due to this on/off mechanism failure. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident Number: I-10173

HPCI DECLARED INOPERABLE

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

"At 1044 EST, Unit 2 high pressure coolant injection (HPCI) system was declared inoperable per technical specification 3.5.1.C.1 during planned surveillance testing due to test equipment failure and subsequent inadvertent isolation of the outboard HPCI turbine exhaust line vacuum breaker primary containment isolation valve. The test equipment was removed, and the vacuum breaker isolation valve was re-opened. HPCI was restored to operable status at 1351.

"Due to inoperability, the system was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72.(b)(3)(v)(D).

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

DEGRADED CONDITION

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

"At 1803 EST on 03/03/25, it was determined that the reactor coolant system pressure boundary does not meet American Society of Mechanical Engineers (ASME) section XI, Table IWB-341 0-1, 'Acceptable Standards' due to a through wall leak where the thimble tube connects to penetration number 6. The cause of this event is currently being investigated. This event is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(A).

"The NRC Resident Inspector has been notified."

FITNESS FOR DUTY - PROGRAMMATIC FAILURE

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

"On March 4, 2025, fitness-for-duty (FFD) program administrators identified a site employee who was required to be part of the FFD program random testing pool, had been inadvertently removed from it on August 5, 2024. The employee's protected area access has been placed on hold in accordance with the station process. The issue has been placed into the site corrective action program for further review and evaluation to determine the cause. This event notification is being made in accordance with 10 CFR 26.719(b)(4)."

The NRC resident inspector has been notified.

EN Revision Text: AGREEMENT STATE REPORT - DAMAGED FIXED GAUGE

The following information was provided by the South Carolina Department of Environmental Services (the Department) via phone and email:

"The licensee informed the Department on February 14, 2025, via telephone, that it had discovered damage (tear) to the film covering the window of the source side of a fixed gauging device. The licensee discovered this event on February 14, 2025. The licensee reported that a representative from the manufacturer of the fixed gauging device was on-site and repaired/replaced the source side window on February 14, 2025. The licensee reported that the the fixed gauging device shutter closed as expected, and the licensee did not report any ongoing health and safety concerns or overexposures.

"The fixed gauging device is a Thermo EGS Gauging LLC, Model TFC-185 (source holder serial number KA2196), housing a 1250 mCi Kr-85 sealed source. The sealed source is a Isotope Product Laboratories Model NER-588. This event is still under investigation by the Department."

THIS MATERIAL EVENT CONTAINS A 'Category 2' LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
