The following was received from the state of South Carolina via email:
"The South Carolina Department of Health and Environmental Control was notified via telephone on 10/31/22 that three fixed gauging device shutters were stuck in the closed position. All three fixed gauging devices are Thermo Fisher Scientific Model 5197 gauging devices, serial numbers B7842, B7847, and B7841. The activity of each gauging device is 100 mCi of Cs-137. The licensee is reporting that all three fixed gauging devices are mounted 12-15 feet above accessible areas. No elevated exposure rates are being reported. Department inspectors will be dispatched to the facility. This event is still under investigation by the South Carolina Department of Health and Environmental Control."
South Carolina Event Number: To be assigned.

PART 21 REPORT - SOLA / HEVI-DUTY UNINTERRUPTIBLE POWER SUPPLY OUT-OF-SPECIFICATION
The following is a synopsis of information provided by Nutherm International via fax:
Nutherm was notified by the customer that a Sola / Hevi-Duty uninterruptible power supply provided under an Exelon purchase order did not power up properly. The unit was returned to Nutherm for failure analysis. Inspection of the internals showed damage to transistors. When energized, the output was out of specification.
This UPS had been supplied for use at Clinton Power Station.
No other units are impacted by this defect or failure to comply. This issue has been identified as a single failure on this component only. This issue will not impact any future procurements.

AGREEMENT STATE REPORT - FOUND MOISTURE DENSITY GAUGE
The following information was received via email from the Colorado Department of Public Health and Environment (the Department):
"During the afternoon of 10/31/22, an InstroTek model 3500 portable gauge was found by a member of the public and turned into Radiation Pros, LLC (specific license CO 1183-01). The isotopes are presumed to be 11 mCi cesium-137 and 44 mCi americium-241:beryllium, but the Department is awaiting confirmation. Radiation Pros, LLC contacted the Department to let us know that they have the InstroTek model 3500 on site and that they contacted InstroTek with the serial number of the portable gauge to find out who owned the gauge. InstroTek let Radiation Pros know that the gauge belongs to Geostruct Engineers, Inc. dba RMG-Rocky Mountain Group, radioactive material license number CO 758-01. Radiation Pros contacted Geostruct Engineers and let them know that they have the portable gauge. Geostruct Engineers picked up the InstroTek portable gauge and transported it back to the licensed location. This event appears to be unrelated to Colorado event CO210032 [EN 55510]."
Colorado Event Report ID No.: CO 220036
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.
