AGREEMENT STATE REPORT - DENSITY GAUGE SHUTTER FAILURE
The following is a summary of the information provided by the New Mexico Radiation Control Bureau via telephone:
A Berthold Model LB7440 density gauge (serial number 2110) installed in a mine was discovered to have a shutter stuck in the open position while removing the gauge from service. The gauge contains a 20 millicurie Cs-137 source. The licensee installed shielding on the gauge and placed it in a storage container. Radiation surveys around the container are between 0.032 and 0.0525 millirem. An authorized service company is scheduled to repair the gauge on March 27, 2023.

IL Event Number: IL230007

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.

EMERGENCY DIESEL GENERATOR ACTUATION

The following information was provided by the licensee via email:

"At 1736 EDT on March 23, 2023, during overcurrent testing of the '2B' [Emergency Safeguards System] ESS Bus, the work group was re-installing tested relays and inadvertently caused a '2B' ESS Bus lockout. This resulted in the '2B' ESS Bus deenergizing and a valid start signal provided to the 'B' Emergency Diesel Generator [EDG]. The 'B' EDG started and functioned as designed.

"This is being reported as an Unplanned Actuation of Systems that Mitigate the Consequences of Significant Events in accordance with 10 CFR 50.72(b)(3)(iv)(A).

"The NRC Resident Inspector has been notified."
