CALIFORNIA AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE DENSITY GAUGE
The following information was received from the State of California via email:
"[A Troxler] Moisture Density Gauge (Serial #18330) was stolen from a parked vehicle at a residence. An unknown subject cut a security cable then took the yellow box containing the device and associated equipment. The box was in the rear bed of a pickup truck. The police department has been notified and are enroute to investigate."
The Troxler contained an 8 mCi AmBe-241 source and a 48 mCi Cs-137 source.
California Report No.: 5010070618
* * * UPDATE ON 7/10/18 AT 1024 EDT FROM KENNETH FUREY TO BETHANY CECERE * * *
The following was received by email from the State of California:
"The Troxler 3440, serial #18330 reported stolen on July 6, 2018 was recovered by the Rancho Cordova Police Department on July 7, 2018 at 2000 PDT after it was dumped in the Walmart parking lot in Rancho Cordova. [A representative] of Youngdahl Consulting took possession of the gauge."
Notified R4DO (Pick), NMSS Events Notification, ILTAB, and CNSNS (Mexico) by 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.

TRANSFORMER FAILURE CAUSES LOSS OF OFFSITE POWER TO UNIT 2
"At 1201 [CDT], Station Auxiliary Transformer 242-2 experienced a bushing failure, resulting in a loss of offsite power to Unit 2. The 2A and 2B Diesel Generators started and sequenced loads onto the Unit 2 ESF buses appropriately. All other buses normally powered from the Station Auxiliary Transformers automatically transferred to the Unit Auxiliary Transformers. ESF Bus 241 and 242 Undervoltage Relays actuated to start the Diesel Generators and the 2A Auxiliary Feedwater Pump started on the 2A Diesel Generator sequencer. ESF Battery Charger 212 tripped at the same time, which was an unexpected condition. DC Bus 212 was cross-tied with DC Bus 112.
"This notification is being made under 10 CFR 50.72(b)3(iv)(A) due to the actuation of both Unit 2 Diesel Generators and the 2A Auxiliary Feedwater Pump.
"The NRC Senior Resident Inspector has been notified."
Currently, offsite power was restored via the Unit 1 Unit Auxiliary Transformer. Both Unit 2 Emergency Diesel Generators have been secured. DC Busses are still cross-tied.
The licensee is currently in a 72-hour shutdown action statement for the loss of offsite power and a 7-day action statement for having the Unit 2 DC Bus cross-tied to Unit 1.
