EN Revision Text: AGREEMENT STATE REPORT - STOLEN RADIOACTIVE GAUGES
The following information was received from Illinois Emergency Management Agency (Agency) via phone and E-mail:
"The Agency was notified early in the morning of 1/31/22 that an Illinois licensee (Lixi, Inc., IL-01339-01) operating in Anaheim, California under reciprocity had two radioactive gauges stolen from their rental car on the afternoon of January 30, 2022 [approximately 1600 PST]. Local law enforcement have been notified and responded. The gauges were padlocked preventing the sources from being used and the keys were not stolen. The California program has been notified and is copied on this correspondence. The licensee appears to have reported the theft in a timely manner.
"The stolen devices were portable fluoroscopes containing approximately 1 Curie of Gd-153 each and were taken from the Staybridge Suites parking garage at 1050 W. Ball Rd. in Anaheim. The police report is 22-15907. The devices were model number TG41 source holders with serial numbers 3217 and 3218. They are marked with the model number 'TG41' and will display 'ON' when the source holder is rotated to expose the source. The radioactive material within the device is in the form of a powder, contained within a tungsten capsule approximately 7mm x 10mm. The source cannot be removed from the device without special tools which were not stolen. If it were somehow removed, it would appear as a stainless steel capsule and is engraved with the word 'Radioactive' and the words 'Gd153', 'C-381' and 'MDSN/LIXI'."
Item Number: IL220003

The following update was received from the California Department of Public Health via E-mail:
"On Sunday, January 30, 2022, [at 2247 PST], the Lixi, Inc. RSO reported to CAL OES [California Governor's Office of Emergency Services] the theft of two Gadolinium-153 sealed sources used in their Lixi pipe profilers, source S/N: 11/21 (943.15 mCi) and source S/N: 12/21 (926.46 mCi), source holders S/N 3217 and 3218). The users had been inspecting pipes at an Albertsons distribution center located in Brea, CA for two weeks. The theft was discovered on Sunday evening, where the locked and alarmed rental GMC Terrain SUV was parked in the hotel parking structure (address above). The employees stored the Lixi profilers with the Gd-153 source holders attached to the Lixi profiler detector system with the sources locked in the shielded position. There was no sign of forced entry, police speculated the thieves had an electronic bypass system of some kind since four cars were broken into. The value of each Lixi profiler is $50,000 to $75,000. Hotel security is reviewing garage camera footage and will update the PD [police department]. The sources had Caution: Radioactive Materials labeling on them. A police report was made with the Anaheim Police Department (Number 22-15907). The licensee will submit a lost/reward ad in the local paper/website and gather additional information for the follow up investigation."

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.

EN Revision Text: AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The following is a synopsis of an email received from the State of Florida:
"[RSO] called and reported that a Nuclear Moisture Density Gauge fell out of the back of his pickup truck while traveling/transporting the gauge from the office to a work site at SR 64 and Dam Rd. The gauge was padlocked in its case and chained on each side of the case to eyelets in the back of the truck using padlocks to secure the chains. Upon arrival at the worksite (Manatee County) the truck tailgate was open and the gauge was missing. The padlocks securing the chains were broken. [RSO] retraced his travel route two times to look for the missing gauge. The gauge was NOT found. [The RSO] reported the incident to both the Manatee County's and Sarasota County's Sheriffs Departments. Sarasota County Sheriff Dept. Case number 22-8695 was issued."
Report identified the sources to be Cesium-137 (10 milliCuries) and Americium-241/Be (50 milliCuries).

EN Revision Text: AGREEMENT STATE REPORT - LOST X-RAY FLUORESCENCE INSTRUMENT
The following was received via email from the Massachusetts Radiation Control Program:
"Atlas ATC of East Hartford, Connecticut (ATC) reported on February 2, 2022, that a Protec LPA-1 x-ray fluorescence instrument, serial number 1331, containing a cobalt-57 sealed source of up to 12 millicuries, was mistakenly transported by an employee from their East Hartford, Connecticut storage location to an asbestos work site, on February 1, 2022, located in Springfield, Massachusetts and that the instrument is missing.
"ATC explained that the instrument was mistakenly transported to and not used at the Springfield, Massachusetts site because the site work was for asbestos analysis and not for lead paint analysis, and however may have somehow become missing at or near the Springfield, Massachusetts site, and that they will be searching the site for the missing instrument.
"ATC further explained that they thought that the instrument may somehow be registered with state of Connecticut and however that they were not familiar with any general or specific license that may have been issued by U.S. Nuclear Regulatory Commission regarding use or storage of the instrument, containing cobalt-57, in Connecticut.
"The reporting requirement is a 30-day telephone report and is of 105 CMR 120.281(A)(2), stolen, lost, or missing licensed radioactive materials in aggregate quantity equal to or greater than 10 times quantity specified in 105 CMR 120.297, Appendix C.
"The Agency considers this event to be open."

EN Revision Text: UNUSUAL EVENT DECLARED DUE TO VISUAL OBSERVATION OF SMOKE AND MULTIPLE FIRE ALARMS IN THE WEST PENETRATION ROOM
The following information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
At 0357 EST on 2/5/22, Oconee Unit 2 declared an Unusual Event due to a multiple fire alarms and visual observance of a smoke filled room in the West Penetration Room (EAL HU 4.1). Unit 2 automatically tripped and entered Mode 3. There was an indication that a release to the environment potentially occurred. Units 1 and 3 remained at 100% power.
The Licensee notified the NRC Resident Inspector, the State, and local authorities.
Notified DHS SWO, FEMA Operations Center, CISA Central, FEMA NWC (email), and DHS Nuclear SSA (email).
* * * UPDATE ON 2/5/22 AT 0748 EST FROM CHUCK CLEMONS TO LLOYD DESOTELL * * *
The following information was provided by the licensee via email:
"At 0343 EST on February 5th, 2022, with Unit 2 in Mode 1 at 100% power, the reactor automatically tripped due to Reactor Coolant Pump (RCP) Flux/Flow Imbalance caused by the simultaneous trip of all 4 RCPs. The cause of the loss of all RCPs is under investigation. The trip was not complex. There was no inoperable equipment prior to the event that contributed to it.
"Operations responded and stabilized the plant. Decay heat is being removed by the Reactor Coolant System (RCS) in natural circulation with normal feedwater flow.
"Due to the Reactor Protection System (RPS) actuation while critical, this event is being reported as a four hour, nonemergency notification per 10 CFR 50.72(b)(2)(iv)(B).
"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 Licensee notified the State and local authorities.
Notified R2DO (Miller)
* * * UPDATE ON 2/5/22 AT 0815 EST FROM CHUCK CLEMONS TO LLOYD DESOTELL * * *
The following information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
At 0811 EST on 2/5/22, Oconee Unit 2 terminated the notification of unusual event because EAL HU 4.1 criteria were no longer met. Unit 2 remains shutdown in Mode 3.
The licensee has notified the State and local authorities and will notify the NRC Resident Inspector.
Notified R2DO (Miller), IRD MOC (Gott), NRR EO (Regan), DHS SWO, FEMA Operations Center, CISA Central, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).
* * * UPDATE ON 2/7/22 AT 2342 EST FROM PATRICK GADSBY TO OSSY FONT * * *
The following information was provided by the licensee via email:
"The follow-up investigation determine that the cause of the trip was determined to be a failed fuse in an undervoltage monitoring circuit for the electrical bus powering the reactor coolant pumps. The trip of the reactor coolant pumps resulted in an automatic reactor trip as designed. The plant responded as expected. There was no fire. The response of the main feedwater system caused an expected increase in temperature in a standby portion of the system which caused the breakdown of the pipe coating producing smoke. There was no release to the environment. The reading of a single instrument was determined to be invalid and other indications supported the conclusion that no release occurred."

The following information was provided by the licensee via email:
"At 0343 EST on February 5th, 2022, with Unit 2 in Mode 1 at 100% power, the reactor automatically tripped due to Reactor Coolant Pump (RCP) Flux/Flow Imbalance caused by the simultaneous trip of all 4 RCPs. The cause of the loss of all RCPs is under investigation. The trip was not complex. There was no inoperable equipment prior to the event that contributed to it.
"Operations responded and stabilized the plant. Decay heat is being removed by the Reactor Coolant System (RCS) in natural circulation with normal feedwater flow.
"Due to the Reactor Protection System (RPS) actuation while critical, this event is being reported as a four hour, nonemergency notification per 10 CFR 50.72(b)(2)(iv)(B).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

The following information was provided by the licensee via email:
"The follow-up investigation determine that the cause of the trip was determined to be a failed fuse in an undervoltage monitoring circuit for the electrical bus powering the reactor coolant pumps. The trip of the reactor coolant pumps resulted in an automatic reactor trip as designed. The plant responded as expected. There was no fire. The response of the main feedwater system caused an expected increase in temperature in a standby portion of the system which caused the breakdown of the pipe coating producing smoke. There was no release to the environment. The reading of a single instrument was determined to be invalid and other indications supported the conclusion that no release occurred."
