| ENS 56924 | 12 January 2024 14:28:00 | The following information was provided by the Minnesota Department of Health (MDH) via email: The MDH was notified on 1/12/2024, by PPL Group LLC, a representative for ERP Iron Ore, LLC Plant 2, of a missing/lost fixed gauge from the licensee's location listed above. PPL Group LLC contracted a waste broker to dispose of the registered generally licensed devices located at the plant. The completed inventory indicates that one device is missing. The missing device is a Berthold model LB74400-CR, serial number 0240/12 containing a 50 mCi Cs-137 source (assay date of 3/20/2014). MDH will do an inspection next week and will continue to keep the NRC informed of the status of our investigation. 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.

| ENS 55317 | 17 June 2021 17:20:00 | The following was received from the Minnesota Department of Health via email: On 5/21/2021 TSI, Inc. received two of three boxes containing radioactive material shipped from NRD, LLC, 2937 Alt Boulevard, Grand Island, NY, 14072. The third package, containing paperwork for 1 NRD model P-2042 static eliminator with an activity of 5 millicuries of Po-210, was received repackaged on the same date. TSI, Inc. contacted NRD and (the common carrier) to inquire about the status of the missing static eliminator. The (common carrier) website indicates that they were unable to deliver the package in question. TSI contacted (the common carrier) who has to date been unable to locate the static eliminator. TSI plans to request that a formal investigation be performed by (the common carrier). The investigation was ongoing at the time of this notification.

| ENS 52608 | 13 March 2017 17:11:00 | The following information was obtained from the state of Minnesota via email: Minnesota Dept. of Health (MDH) was notified by phone message March 10, 2017. The message was retrieved March 13, 2017 by the RAM (Radioactive Material) unit Supervisor. MDH visited the site March 13, 2017 and gathered the following information regarding the source holder. Category: External EMS Housings Source Model: P-2608-100 (Co-60) Gauge Model: LB 300 ML Manufacture Date: 10/2013 Manufacturer: Berthold Systems, Inc. Source Number: 1816-10-13 (mold housing 12) Original Activity: 1.5 mCi Current Activity: 1.4050 mCi The licensee is a steel processor and the incident involved molten steel encasing the source holder, locking the shutter in an open position. This is not a typical occurrence. The licensee is working with a consultant (Applied Health Physics) to develop a plan for removing the source holder from the mold and determining whether the source holder is repairable or if it needs to be disposed of. |
