AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The following information was provided by the Florida Bureau of Radiation Control (BRC) via email:
"The Florida BRC received initial notification at 1830 [EST] from licensee (4696-7) UES Professional Solutions of a lost in transit density gauge. More information about this incident was received at 2000 from the licensee's radiation safety officer (RSO).
"The licensee's technician noticed the soil moisture density gauge was missing from the back of his pick-up truck around 1530 [on 11/19/2024] when he returned to the job site after lunch. He realized the tailgate was open and, when he went to close it, he noticed the gauge wasn't there. The technician last used the gauge during a subgrade test right before he went to lunch around 1430. He thinks the gauge was lost while at lunch. The technician called his supervisor at 1730, who contacted the RSO. The employee admitted that the gauge case was not locked, but the gauge was secure in the case. The RSO and technician retraced the route several times, but were not able to locate the gauge.
"The density gauge is a Troxler [model] 3430 with serial number 31852 [nominally containing 8 mCi of Cs-137 and 40 mCi of Am-241:Be]."
Florida Incident Number: FL24-111
* * * UPDATE ON 11/20/2024 AT 1522 EST FROM MARK SEIDENSTICKER TO ERNEST WEST * * *
"A Jacksonville area inspector responded [on 11/20/2024] and reported their findings. UES Professional Solutions terminated the employee [on 11/19/2024] and used GPS tracking to retrace the route, but did not find the gauge. The Jacksonville Police Department was notified and is also waiting on video surveillance footage from the [restaurant] where the employee stopped."
Notified R1DO (Bickett), NMSS Events Notification (email), and ILTAB (email).
* * * UPDATE ON 11/21/2024 AT 0710 EST FROM MARK SEIDENSTICKER TO TENISHA MEADOWS * * *
"At 1630 EST on Wednesday 11/20/2024, the RSO called and stated an individual found the gauge. The licensee has the gauge back in their possession and are sending it to Troxler for testing before returning to service."
Notified R1DO (Bickett), NMSS Events Notification (email), and ILTAB (email).
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 - STUCK SHUTTER
The following information was provided by the Louisiana Department of Environmental Quality (LDEQ) via email:
"On November 20, 2024, LDEQ was notified by Blue Cube Operations LLC, that during a semi-annual equipment inspection, it was determined that a level density gauge shutter was malfunctioning and would not fully close.
"The density gauge was a TN Technologies Inc. Model: 5201 serial number: B465, and equipped with a TN Technologies Inc. Cs-137 100 mCi source - serial number: GK-9492.
"No release or exposure to personnel [occurred]. Blue Cube Operations called the vendor to service the level density gauge. The vendor removed the fixed gauge from operations. The fixed gauge with source was secured and is waiting for disposal."

EN Revision Text: MANUAL REACTOR TRIP
The following information was provided by the licensee via phone and email:
"At 1350 [EST] on 11/19/2024, with Unit 1 in mode 1 at 100 percent power, the reactor was manually tripped due to an automatic trip of the `B' main feedwater pump turbine. The reactor trip was uncomplicated with all systems responding normally post trip. Operations stabilized the plant in mode 3. Decay heat removal is being accomplished by the steam dumps to the condenser.
"Emergency feedwater actuated due to low-low steam generator level, as expected.
"This event is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A).
"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 'B' main feedwater pump turbine trip is under investigation.
