Title	Damaged Gauge
Event Description	The following information was provided by the North Dakota Department of Environmental Quality (the Department) via email: On June 12, 2025, at 1647 MDT, the Department received a notification from Minn-Dak Farmers Cooperative reporting an equipment issue identified on June 11, 2025. The issue involved a fixed nuclear gauge (Thermo MeasureTech model 7063, S/N: 1519A), containing a 500 millicurie (original activity) Cs-137 sealed source. The Department is waiting for specific sealed source information. The facility is transitioning into a scheduled plant maintenance and cleaning downtime period. As part of this downtime, the radiation safety officer (RSO) planned to replace the referenced fixed gauge. During this process, it was discovered that the fixed tab used to secure the shutter arm in the locked-out position had broken off. Although the shutter mechanism remains operational, the gauge can no longer be properly locked out due to the missing tab. There is no visible damage to the source holder's structure or housing. The gauge continues to function securely in its installed position and does not present an operational safety concern. The last shutter check was in March 2025, and there was no indication of damage to the fixed gauge [at that time]. No overexposures occurred during this event. Currently, the RSO is in contact with the vendor for plans to remove and dispose of the gauge and replace it with a new gauge. This is reported per 10 CFR 30.50(b)(2). ND Event Number: ND250002
