EN Revision Text: AGREEMENT STATE REPORT - STUCK SHUTTER

The following information was provided by the New Jersey Department of Environmental Protection via email:

"On December 5, 2024, the licensee became aware of a shutter that could not fully close but was able to return to the fully open, operative position. The shutter failure was identified while performing a routine six-month fixed gauge shutter check. The fixed gauge is located eight feet above a walking platform which is only accessible to licensee staff via ladder, scaffolding or other means. No members of the public have access to this location.

"The shutter is currently in its normal, open position. No maintenance activities are scheduled which would require closure of the shutter.

"The licensee has a contract with the manufacturer and has scheduled them to assess this situation and make any necessary repairs.

"The shutter holder contains a Cs-137 sealed source (model A-2102) with maximum activity of 300 mCi.

"This event is reportable under 10 CFR 30.50(b)(2) [NJAC 7:28-51.1]"

Equipment information:
Model number: SH-F2
Serial number: 0362CG
Manufacturer: Vega Americas, Inc.

New Jersey Event Report ID number: To be determined

* * * UPDATE ON 1/19/2025 AT 1321 EDT FROM JACK TWAY TO SAMUEL COLVARD * * *

The following information was provided by the New Jersey Department of Environmental Protection via email:

"On January 8, 2025, the Phillips 66 contractor, Vega Americas Inc, removed the device with the stuck shutter and placed it into storage at the facility awaiting disposal. A new device was installed by the manufacturer in its place.

"The device serial number was originally reported as 0362CG. This serial number is incorrect. The serial number of the source is 37053G (50 mCi), which was installed in device model SHF1B, manufactured by Vega. The licensee is contacting Vega to obtain the correct device serial number.

"This incident is now considered closed by the state."

AGREEMENT STATE REPORT - MEDICAL EVENT

The following was provided by the Utah Division of Waste Management and Radiation Control (the Department) via email:

At 1000 MST, on 01/10/25, the Utah Cancer Specialists reported a medical event to the Department.

"A Patient was undergoing a Lutathera treatment (contains Lu-177). During treatment, the patient was to receive an amino acid infusion prior to the radiopharmaceutical administration, as per standard protocol. Initially, saline was started; however, the saline line remained clamped, preventing the amino acid infusion from commencing. Fifteen minutes after administering the radiopharmaceutical, it was observed that the amino acids had not been infused. Consequently, the Lutathera treatment was paused, the amino acid infusion was initiated, and subsequently, the Lutathera administration was completed."

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

The prescribed activity was 200 mCi of Lu-177 to the patient. The dose estimate, which is still being evaluated, falls under 10 CFR 35.3045 Subpart M.

Utah Event Report Number: UT250001

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 - DAMAGED SOURCE / UNPLANNED CONTAMINATION
The following information was provided by the Texas Department of State Health Services (The Department) via email:

"On January 14, 2025, the Department was notified by the licensee's radiation safety officer (RSO) who reported a source had been damaged. The RSO could not provide specific information on the source other than that it was a resin bead source containing 200 millicuries (original activity) of cesium - 137 contained in a plastic vial. The RSO stated they had been notified on January 13, 2025, at 1430 hours (CST) that the plastic capsule that contained the resin was found cracked and some of the resin had leaked out of the source and onto the floor. The area of the spill was isolated. They performed contamination surveys and found the contamination was contained in the room where the source was used. They surveyed all personnel who had entered the room and no individual was found to have been contaminated. The room was decontaminated and all but a few spots had been cleaned to background levels. The remaining areas were covered with a gel type material to trap the contamination and, when removed, should remove the contamination. The RSO will provide additional information on the source later.

"Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT: DAMAGED GAUGE
The following information was provided by the Texas Department of State Health Services (The Department) via email:

"On January 14, 2025, the Department was notified by the licensee that on January 13, 2025, a Vega model SH-F2 shutter failed to close during routine testing. The gauge contains a 1,000 millicurie (original activity) cesium - 137 source. Open is the normal operating position for the gauge. The licensee stated there is no risk of radiation exposure to members of the general public or radiation workers due to the failure. The licensee will contact a service provider to schedule repair of the gauge. Additional information will be provided as it is received in accordance with SA-300."

MANUAL TRIP WHILE SHUTDOWN

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

"At 0950 EST, with Unit 2 in mode 3 at 0 percent power, the reactor was manually tripped due to group 2 of control rod bank D failing to withdraw during rod drop testing. The trip was not complex, with all systems responding normally post-trip.

"Operations responded and stabilized the plant. Decay heat is being removed by the auxiliary feedwater and steam dump systems. Unit 1 is not affected.

"At the time of the event, Unit 2 was not critical. Therefore, this event is being reported as an eight-hour, non-emergency notification in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the reactor protection system.

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

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

Four controls rods failed to move on demand. All control rods inserted on the trip.

AUTOMATIC REACTOR TRIP

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

"At 0203 EST on 01/17/2025, with Unit 1 in mode 1 at 100 percent power, the reactor automatically tripped due to a main turbine trip. The trip was not complex, with all systems responding normally post-trip.

"Operations responded and stabilized the plant. Decay heat is being removed by discharging steam to the main condenser using the steam dump system and the auxiliary feedwater (AFW) system. Unit 2 is not affected.

"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). The expected actuation of the AFW system (an engineered safety feature) is being reported as an eight-hour report under 10 CFR 50.72(b)(3)(iv)(A).

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

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

The cause of the turbine trip is under investigation.
