AGREEMENT STATE REPORT - STOLEN MOISTURE GAUGE
The following was received from the California Department of Public Health, Radiologic Health Branch (RHB) via email:
"On March 6, 2023, the Radiation Safety Officer for G3 Quality, Inc. contacted a Licensing Health Physicist (instead of an Inspection Health Physicist) within the California Radiologic Health Branch regarding a moisture density gauge that was stolen from a jobsite in Moreno Valley, California. The gauge is a Troxler model 3450, serial number 72761 (8 millicuries of Cs-137 (nominal) and 40 millicuries of Am:Be-241 (nominal)). On March 4, 2023, after arriving at the jobsite, the gauge operator took the gauge out of the transport case, placed the gauge on the bed of their vehicle to perform a standard count. After that was completed, the operator then walked over to the site supervisor to discuss the job, leaving the gauge sitting on the bed of the truck, outside of its transport case and without a lock on the handle. When he returned to the vehicle, the operator discovered the gauge was missing. After searching the area for the gauge, the operator contacted their supervisor. The Moreno Valley Police Department was contacted and a police report was made. The licensee has offered a reward for return of the gauge. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health.
"The reporting of this event was delayed due to a communication issue within the CA Radiologic Health Branch."
California NMED Number: 030623
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.

AUTOMATIC ACTUATION OF REACTOR PROTECTION SYSTEM (RPS)
The following information was provided by the licensee via email:
"At 0910 [CST], with Unit 2 in Mode 4 at 0 percent power, an actuation of a reactor scram on low charging water header pressure occurred during restoration from hydrostatic test conditions. All control rods were already fully inserted prior to the receipt of the scram signal.
"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the Unit 2 RPS system.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
