AGREEMENT STATE REPORT - LOST/STOLEN PORTABLE GAUGE
The following information was provided by the California Department of Public Health, Radiologic Health Branch (RHB) via email:
"The radiation safety officer for Giles Engineering contacted the RHB in Sacramento to report a lost/stolen CPN portable nuclear gauge, model MC-1, serial number MD71003961. This gauge contains two radioactive sealed sources: 370 MBq (10 mCi) of Cs-137 and 1.9 GBq (50 mCi) of Am-241.
"The loss / theft occurred about on Friday August 9, 2024, while in Palm Springs at a job project. The CPN [brand] gauge was secured in the rear of the company pickup truck, locked inside the locked case. The gauge operator got stuck in deep sand at the job site, so he removed the security chain to get pulled out. He failed to re-secure the portable gauge to the pick-up truck and noticed it was missing while he was stopped at a local gas station. A police report was filed with Palm Springs police department. Maurer Technical Services and Instrotek were also notified."
California 5010 Number: 081224
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.

PART 21 - NON COMPLIANT CONTACTORS
The following is a synopsis of information provided by MPR Associates, Inc. (MPR) via fax:
On August 9, 2024, MPR received information that electrical contactors (Models AF80 and AF116) provided by Asea Brown Boveri Ltd. (ABB) contain a microcontroller. The fact that these contactors contain a microcontroller was not included in MPR's analysis during their commercial grade dedication process. Two contactors were supplied to Beaver Valley Power Station (ABB AF116-30-11-13) where one was installed in the excitation system for one emergency diesel generator. Five contactors were supplied to Davis-Besse Nuclear Power Station (ABB AF116-30-11-13), but none were installed.
MPR is currently working to provide information to support continued use of the installed contactors. MPR is also working to identify a replacement contactor that is suitable for the application.
